Thunderstorm activity across the state was much tamer than in recent weeks with unseasonably dry conditions over much of Iowa. Only stations in north-central Iowa reported positive departures in the range of 2.00-4.00 inches. Temperatures remained warmer than average, though moderated from last week; the statewide average temperature was 77.4 degrees, 2.4 degrees above normal.

Poor air quality gradually improved through Sunday (5^th) afternoon as variable, light winds increased under mostly sunny skies and temperatures in the low to mid 80s. Spotty thundershowers formed in eastern Iowa towards the evening hours, leaving behind 0.21 inch of rain in Ottumwa (Wapello County) and 0.23 inch in Nashua (Floyd County). Patchy fog was reported from western to southeastern Iowa around sunrise on Monday (6^th) with morning temperatures in the upper 60s and low 70s. Daytime conditions were mostly sunny with highs in the mid 80s with southerly to easterly shifting winds west to east across the state. A cluster of storms pushed into north-central Iowa in the hours before sunrise on Tuesday (7^th), though the complex quickly dissipated. Totals were very isolated with only a handful of stations observing rainfall; Estherville (Emmet County) registered 1.07 inches to 1.20 inches in Swea City (Kossuth County). Partly sunny skies developed into the afternoon with temperatures in the mid to upper 80s and light winds. Clouds hung around into Wednesday (8^th) as winds shifted to a southerly direction. Showers and thunderstorms skirted the Iowa-Minnesota border during the morning hours as southerly flow pumped low-level moisture into the Upper Midwest. Afternoon temperatures returned to the 80s with dew points pushing into the 70s. A surface front moved into the unstable airmass over the evening hours, firing a line of strong thunderstorms in northeastern Iowa with broken segments in western to central Iowa; several 60-mph wind gusts were observed. The line consolidated as it moved southeast with additional development in west-central Iowa. The complex fell apart by 7:00 am on Thursday (9^th), with the highest amounts occurring across central and northeastern Iowa. Rainfall totaled 2.33 inches in Ames (Story County), while totals at three gauges in Osage (Mitchell County) ranged from 3.32 to 4.79 inches. A swath extending from east-central to western Iowa also registered 0.75–1.25 inches of rainfall.

Afternoon temperatures were seasonal in the low 80s, with lower relative humidity and mostly cloudy skies. Scattered thundershowers developed over eastern Iowa and persisted into Friday (10^th) morning. Additional showers moved through southern Iowa as a low pressure center pushed through northern Missouri. Atmospheric conditions in the afternoon hours were conducive to funnel clouds across northern and eastern Iowa; a brief touchdown was reported near Swaledale (Cerro Gordo County). Thunderstorms continued to pop up over southern Iowa after midnight before moving off as the disturbance traveled east. South-central and southeastern stations reported the most rainfall with 1.40 inches in Murray (Clarke County) and 2.46 inches in Ottumwa. Most stations reporting rainfall had at least a few tenths of an inch. Saturday (11^th) was a pleasant, sunshine-filled day with highs in the low to mid 80s and light easterly winds. Starry skies held into Sunday (12^th) morning with temperatures in the mid to upper 60s and patchy fog.

Weekly precipitation totals ranged from no measurable amounts at multiple eastern and northern stations to 4.88 inches in Osage. The statewide weekly average precipitation was 0.66 inch; the normal is 0.97 inch. Lamoni (Decatur County) reported the week’s high temperature of 93 degrees on the 8^th, six degrees above normal. Greenfield (Adair County) reported the week’s low temperature of 53 degrees on the 11^th, 11 degrees below normal.

Iowa Secretary of Agriculture Mike Naig commented on the Iowa Crop Progress and Condition Report released by the USDA National Agricultural Statistics Service. The report is released weekly April through November.

Additionally, the Iowa Department of Agriculture and Land Stewardship provides a weather summary each week during this time.

“Late last week, parts of central Iowa received 8-11 inches of rain in just 36 hours, more than twice the rainfall typically expected during the entire month of July. There have been widespread reports of flooded fields and basements, swollen streams and rivers, and impacts to roads and other infrastructure. Our hearts go out to the lowans and communities affected by the flooding as recovery efforts continue,” Secretary Naig said. “At the same time, other areas of the state, including drought-affected portions of northwest and north-central Iowa, received much-needed rainfall. Looking ahead, the forecast calls for additional chances of thunderstorms across much of the state through midweek, with warmer and drier conditions expected through mid-July.”

Weather summary

A “Ring of Fire” pattern around the periphery of the persisting heat dome brought several days of active weather with thunderstorms delivering significant rain totals to northwest, central and northeast Iowa. Some stations reported nearly 250 percent of normal, which represents more than two months’ worth of rainfall over just 36 hours. Unseasonably warm temperatures held on with the warmest conditions in eastern Iowa; the statewide average temperature was 79.0 degrees, 6.0 degrees above normal.

A line of severe thunderstorms sped across northern Iowa before dissipating over the state’s far eastern extent during Sunday (28^th) afternoon. Britt (Hancock County) experienced a 58-mph wind gust while 2-inch hail was reported in Delmar (Clinton County). A wide swath of north-central to northeast Iowa collected at least 1.00 inch with 2.85 inches in Nashua (Floyd County). Starry skies were visible into Monday (29^th) with southerly winds, high dew points and air temperatures on the mid to upper 70s. Winds became gusty by the afternoon hours as temperatures rose into the upper 80s and low 90s. A line of stronger thunderstorms moved into northwest Iowa after sunset, bringing strong wind gusts and heavy downpours.

Fostoria (Dickinson County) observed a wind gust of 75 miles per hour while Ireton (Sioux County) reported 1.45 inches of rain. Several stations in the northwest registered 0.75 to 1.25 inches with lesser totals farther east. Afternoon conditions were similar to the previous day with winds shifting slightly to the southwest. Stronger storms redeveloped after midnight on Tuesday (30^th) along the Iowa-Nebraska border and pushed into the northwest corner. More showers fanned out across the state’s northwestern one-third through the day as instability built up. Initial isolated thunderstorms fired during the late evening hours with some cells becoming severe warned; a short-lived weak tornado was spotted by a chaser near Stacyville (Mitchell County). Thunderstorms continued across northern Iowa into Wednesday (1^st) with morning temperatures holding in the 70s.

A more compact line of severe thunderstorms moved into northeastern Iowa into the early afternoon hours, bringing 3.5-inch hail to Maynard (Fayette County) along with a few high wind reports. Additional thunderstorms blossomed over central Iowa along existing outflow boundaries into the evening hours, feeding off ample atmospheric water vapor. Thunderstorms overspread much of the state on Thursday (2^nd) with concentrated, slow moving cells training over the same locations and saturating soil profiles. As the complex slowly dissipated, streams and rivers became inundated with runoff with stations collecting more than a month’s worth of rainfall. Nearly 200 stations had at least 2 inches with 42 over 3 inches. The highest totals were found from Nevada (Story County) which reported 6.50 inches to two Polk City (Polk County) gauges that registered 8.90 to 9.41 inches; the statewide average rainfall over the 24-hour period was 1.30 inches. 

Friday (3^rd) morning was generally quiet with patchy fog over northern Iowa and cloud cover east. Temperatures held in the upper 60s and low 70s with light and variable winds.

Winds shifted northerly later in the day as a weak cold front dropped through the state.

Daytime highs were more comfortable, reaching into the low 80s with less surface humidity.

Anomalous mid-level moisture was an ample source for thunderstorms to reform in southwest and southeast Iowa toward sunset. Storms filled in across central Iowa into the early morning hours of Saturday (4^th), producing moderate to heavy rain over soaked landscapes.

Story County became the bullseye for the heaviest amounts with five stations in Ames measuring between 4.20 to 6.36 inches. Nearly 120 stations hit 1.00 inch with 43 stations at 2.00 inches and a statewide average of 0.83 inch. Iowans celebrating the 250th anniversary of the signing of the Declaration of Independence had to dodge scattered thunderstorms over northern and eastern Iowa toward dusk. Fireworks, no wind and higher dew points led to air quality issues into Sunday (5^th). Rainfall totals were generally under a few tenths of an inch, though Le Claire (Scott County) reported 1.02 inches with 1.86 inches in Clarence (Cedar County).

Weekly precipitation totals ranged from no measurable amounts at multiple southern stations to 10.99 inches in Polk City (Polk County). The statewide weekly average precipitation was 2.53 inches; more than double the normal 1.10 inches. Little Sioux (Harrison County) and Sioux City Airport (Woodbury County) reported the week’s high temperature of 97 degrees on the 28th and 29th, respectively, on average 12 degrees above normal. Sanborn (O’Brien County) reported the week’s low temperature of 56 degrees on the 5th, six degrees below normal.

Overall cooler conditions held across Iowa through the reporting period as a heat dome developed over the southeastern United States towards the weekend; the statewide average temperature was 68.2 degrees, 3.9 degrees below normal. Portions of northwest and southeast Iowa experienced wetter than normal conditions with the rest of the state drier than normal.

Moderate showers persisted throughout Sunday (21st) afternoon in central and eastern Iowa as a low pressure center exited the state. Most stations across eastern Iowa received totals in the 0.50-0.75 inch range with the highest totals along the Iowa-Illinois border where nearly 15 stations observed at least 2.00 inches. Keokuk Lock and Dam (Lee County) registered 2.02 inches while Muscatine (Muscatine County) reported 2.55 inches with a statewide average of 0.54 inch. Monday (22nd) morning dawned with light northerly winds and temperatures in the mid to upper 50s with patchy fog in central to northeast Iowa. Daytime conditions were partly cloudy with variable winds and highs in the mid to upper 70s. Overcast skies developed into Tuesday (23rd) over portions of northern Iowa, helping hold morning lows in the low to mid 60s. Temperatures in southern and western Iowa held in the low to mid 50s under clear skies. Wind turned southerly and became gusty through the day as clouds increased, helping temperatures push into the upper 70s and low 80s with rising humidity. A cold front moved into the northwest corner after midnight on Wednesday (24th), producing scattered showers and thunderstorms that propagated southeast across the state into late morning. Stations over the state’s northern one-third reported general totals in the range of 0.10-0.25 inch with isolated pockets of higher totals in western and northeast Iowa; Hornick (Woodbury County) collected 1.24 inches while 1.29 inches was observed in Lansing (Allamakee County). Isolated strong thunderstorms fired over northeast Iowa as the front moved out of the state, leaving behind moderate rainfall totals from 0.22 inch in Asbury (Dubuque County) to 0.49 inch in McGregor (Clayton County).

Spotty thundershowers formed in southwestern Iowa around sunrise on Thursday (25th), quickly dissipating over a few hours. Conditions were pleasant with highs rising into the mid to upper 70s and mostly sunny skies statewide. Scattered showers formed in western Iowa towards the evening hours and pushed across portions of southern and northern Iowa into Friday (26th) morning. Rainfall ended after noon with most stations having measurable amounts over northern Iowa picking up at most 0.10 inch. Locations in southwest Iowa recorded higher totals with widespread 0.25 inch reports; two Decatur County stations had the highest totals with 0.23 inch in Davis City to 0.31 inch at Lamoni Municipal Airport. Thick stratus clouds overspread much of the state early on Saturday (27th) with fog and drizzle reported across southern Iowa and overall temperatures in the upper 50s north to low 60s south. Cloud cover persisted all day with southeasterly winds and pleasant temperatures in the 70s, though humidity values were above 80 percent. Barometric pressure dropped in the northwest as an intense cluster of thunderstorms pushed across the South Dakota border. Hail and high winds were reported along with moderate to heavy rainfall with interspersed downpours. Thirty northwest to north-central stations observed 1.00 inch of rainfall, six of them at or above 2.00 inches; Sibley (Osceola County) had 2.15 inches with 2.73 inches in West Bend (Palo Alto County).

Weekly precipitation totals ranged from no measurable amounts at several central and southwestern stations to 3.16 inches in West Bend. The statewide weekly average precipitation was 0.72 inch; the normal is 1.20 inches. Mapleton (Monona County) reported the week’s high temperature of 90 degrees on the 27th, seven degrees above normal.

A less active pattern compared to previous weeks brought one day of severe weather and then widespread, spring-like rainfall by the end of the week. Rainfall totals were highest over southeast Iowa. A shift to cooler temperatures also greeted Iowans with negative departures approaching seven degrees; the statewide average temperature was 67.8 degrees, 4.3 degrees below normal.

Chilly northwesterly winds and stratocumulus clouds slowly gave way to pleasant conditions through Sunday (14^th) afternoon. Temperatures pushed into the upper 60s and low 70s as winds became gustier under mostly sunny skies. Winds died down and turned westerly overnight into Monday (15^th) under starry conditions and morning lows in the 50s. Daytime temperatures were near-seasonal, warming into the upper 70s with spotty cloud cover. Showers and a few thunderstorms pushed across the state from the evening to overnight hours as a weak cold front swept southeast. Most stations that had measurable totals observed less than 0.10 inch, though West Point (Lee County) registered 0.17 inch. Winds swung back around to the northwest, becoming gusty into Tuesday (16^th) afternoon with clouds clearing in eastern Iowa and temperatures in the mid to upper 70s. Winds turned southerly towards midnight as a strong low pressure disturbance propagated along the Iowa-Minnesota border towards sunrise. Initial thunderstorms in northwest Iowa coalesced into a line along the low’s attendant cold front and quickly strengthened over north-central Iowa. As a strong rear-inflow jet pushed into the center of the line, the squall bowed out and intensified. Heavy rain and severe wind gusts were reported along the path from 64 mph near Storm Lake (Buena Vista County) to 75 mph in Walford (Linn County); the strongest gust of 94 mph was observed near Marshalltown (Marshall County), producing crop and structural damage. The line increased in aerial extent in southeastern Iowa where widespread flash flood warnings were issued. The complex exited eastern Iowa around noon on Wednesday (17^th). Additional severe thunderstorms fired in northeastern Iowa by the late afternoon hours, producing a longer track EF-2 rated tornado in Elon (Allamakee County) which crossed the Mississippi River into Wisconsin. A swath of stations from north-central to eastern Iowa reported higher totals with nearly 130 stations hitting at least 1.00 inch; more than 25 stations picked up more than 2.00 inches with 2.55 inches in Ely (Linn County) to 2.95 inches in Story City (Story County). Notably, four stations in Muscatine County reported totals from 3.25-4.33 inches.

Thursday (18^th) dawned with clouds north and clear skies south with morning lows in the upper 50s to low 60s. Cloud cover increased over the state with afternoon temperatures holding in the mid 70s. Clear skies persisted into Friday (19^th) with calm winds and morning temperatures in the low 50s north to low 60s south. Scattered showers crossed the state through the daytime hours as another cold front moved through Iowa. Behind the front, temperatures were in the low 60s while upper 70s were found in southeast Iowa. Rain totals reported at 7:00 am on Saturday (20^th) were generally light, though airports in Ames (Story County) and Waterloo (Black Hawk County) registered 0.23 inch and 0.41 inch, respectively. Afternoon conditions were pleasant with ample sunshine and highs in the mid to upper 70s. Clouds increased over southwestern Iowa around sunset as moderate showers spun into the state. Showers overspread southern Iowa into Sunday (21^st) where most southwest stations collected between 0.75 to 1.50 inches; Council Bluffs (Pottawattamie County) received between 2.98 to 3.09 inches at two stations.

Weekly precipitation totals ranged from a trace near Carroll (Carroll County) to 4.41 inches in Muscatine (Muscatine County). The statewide weekly average precipitation was 1.66 inches; the normal is 1.20 inches. Lamoni (Decatur County) reported the week’s high temperature of 89 degrees on the 17^th, five degrees above normal. Airports in Sioux City (Woodbury County) and Spencer (Clay County) reported the week’s low temperature of 43 degrees on the 15^th, on average 16 degrees below normal.

Weather summary

An active pattern over Iowa brought multiple waves of severe weather, including a derecho and tornadoes. Heavy rain across portions of the state also produced localized flooding and unseasonably high rainfall totals. Temperatures remained above average with departures in the four to six degree range; the statewide average temperature was 73.2 degrees, 4.2 degrees above normal.

A low pressure system moving through eastern Iowa continued to bring showers and a few thunderstorms across eastern Iowa into Sunday (7^th) afternoon. Scattered showers also brought measurable but lower totals over western Iowa. Most stations in eastern Iowa reported at least 0.50 inch with the highest totals from 2.00 inches in Iowa City (Johnson County) to 3.56 inches in Elma (Howard County). Southeasterly winds, overcast conditions and temperatures in the low 70s persisted on Monday (8^th) morning with showers lingering in eastern Iowa. Skies cleared across western Iowa into the afternoon hours with clouds and light rain hanging on in eastern Iowa. Daytime highs varied from the upper 80s west where sunshine was present to mid 70s east. Rain totals reported at 7:00 am on Tuesday (9^th) were highest in east-central Iowa where 2.20 inches were observed in Parnell (Iowa County) and 3.03 inches in Vinton (Benton County). Daytime conditions were mostly sunny with gusty southerly winds and temperatures in the mid 80s to low 90s; dewpoints in the upper 60s and low 70s pushed heat index values into the low 100s.

A low pressure center pushing northeast into Minnesota fired strong thunderstorms along the cold front over northwest Iowa into the morning hours on Wednesday (10^th). A secondary complex of thunderstorms formed ahead of the surface boundary where moisture, lift and instability were ample. The thunderstorms coalesced into a squall line as they approached the Iowa-Illinois border. Widespread wind gusts above 58 mph were observed as the line pushed across Illinois and farther east; this line would later meet the criteria for a derecho. Several hours later, the cold front slammed into an unstable airmass and quickly fired severe thunderstorms from south-central to eastern Iowa. Several weak tornadoes were observed in Decatur and Davis counties along with large hail and strong wind gusts. A second low pressure disturbance followed the wake of the previous day’s activity, as rapidly developing thunderstorms intensified into a tornado-warned line in southwest Iowa by daybreak on Thursday (11^th). Several tornadoes were spawned along with co-located straight-line wind gusts and isolated large hail; Essex (Page County) measured a 90-mph wind gust while large grain bins were crumpled and thrown off their footings near Villisca (Page County). Nearly 45 stations from southern to eastern Iowa registered at least 2.00 inches with the highest totals of 4.15 inches in Davis City (Decatur County) to 6.63 inches in Russell (Lucas County); the statewide average rainfall was 0.90 inch.

As the squall line approached eastern Iowa, it began to bow out, producing numerous straight-line wind reports. Winds turned northwesterly behind the passing system, with the atmosphere over southeastern Iowa recovering from morning convection, again becoming highly unstable. Strong southeasterly winds were aided with low-level wind shear as thunderstorms reformed into the afternoon hours. One additional tornado, “needle-like” in appearance, was observed near Ainsworth (Washington County). The line lost some strength as it moved out of Iowa before sunset. Rain totals registered on Friday (12^th) showed almost 140 stations hitting at least 1.00 inch. Stations farther east experienced the highest amounts with 2.50 inches in Fayette (Fayette County) and 2.85 inches in Monticello (Jones County). The daytime hours were pleasant as temperatures rose into the upper 70s and lower 80s with sunshine and westerly winds. Another round of showers and thunderstorms along a cold front moved through Saturday (13^th) with many stations over the state’s southwest half collecting amounts in the 0.25-0.75 inch range. Sunday (14^th) dawned with lows in the upper 50s and low 60s with gusty northwesterly winds and fair weather cumulus over northern Iowa.   

Weekly precipitation totals ranged 0.04 inch at Spencer Municipal Airport (Clay County) to 7.44 inches in Russell. The statewide weekly average precipitation was 2.37 inches; the normal is 1.27 inches. Several stations reported the week’s high temperature of 95 degrees on the 9^th, on average 15 degrees above normal. Cherokee (Cherokee County) and Spencer Municipal Airport reported the week’s low temperature of 47 degrees on the 14^th, on average 11 degrees below normal.

June began with unseasonably wet conditions across a southwest to northeast swath of Iowa. Beneficial rains fell after the 35^th driest May in 154 years of statewide records. Unseasonable warmth persisted with the highest departures from central to western Iowa; the statewide average temperature was 72.8 degrees, 5.9 degrees above normal.

Light rain was reported into Sunday (31^st) afternoon from central to northeast Iowa. Stronger thunderstorms fired along the state’s western border after sunset. There were a handful of reports of large hail and straight-line winds, causing some isolated tree damage. Locally heavy rainfall was also reported at multiple stations with 1.00 inch in Persia (Harrison County) to 2.16 inches in Bedford (Taylor County). Monday (1^st) dawned with morning lows in the 60s, mostly clear skies and light winds generally out of the east. Afternoon temperatures rose into the upper 80s in west-central Iowa which helped fuel isolated thunderstorms that produced some large hail. While rainfall was concentrated over a smaller area, Perry (Dallas County) collected 0.61 inch while two stations in Jefferson (Green County) registered 0.80 to 1.12 inches. Winds held easterly into Tuesday (2^nd) with morning temperatures in the upper 50s southeast to mid 60s northwest with a few passing clouds in central Iowa. Daytime conditions were pleasant, as highs reached into the upper 70s and low 80s with low relative humidity and ample sunshine. Winds swung to the south overnight into Wednesday (3^rd) becoming gusty by the afternoon hours across southern Iowa. Afternoon conditions were mostly clear except for clouds pushing into southwestern Iowa and statewide temperatures in the low 80s.

Clouds increased over western Iowa through the early morning hours on Thursday (4^th) as a low pressure center pushed along the Iowa-Minnesota border. As the attendant cold front swept across the state through the daytime hours, a line of showers and thunderstorms consolidated as it moved into central Iowa. Some embedded cells produced moderate to heavy rainfall as the line advanced into eastern Iowa. More than 130 stations reported at least an inch with nearly 30 collecting at least two inches. The highest totals were found from central to northeast Iowa; Story City (Story County) observed 2.50 inches with two Buchanan County stations, Independence and Winthrop registering 3.52 and 4.00 inches, respectively. Northwestern and southeastern stations reported measurable totals, though generally in the 0.25-0.50 inch range with an overall statewide average of 0.84 inch. Friday (5^th) began with foggy conditions over much of the state due to overnight rainfall, light winds and ample low-level humidity. Morning temperatures varied from the mid 60s northwest to low 70s southeast. Skies remained mostly cloudy through the day with southwesterly winds and temperatures in the low 80s. Slow-moving thunderstorms fired over southern Iowa during the evening hours after ample heating and in the presence of anomalous atmospheric water vapor availability. Several cells became tornado warned, though no touchdowns were reported. Very heavy rain fell across Lucas County, where flooded basements and washed-out roads were reported. Williamson observed 3.40 inches with 4.09 inches in Chariton and 4.62 inches in Russell.  Conditions stabilized into Saturday (6^th) morning with clear skies and light, variable winds. Ideal weather persisted throughout the day with temperatures warming into the 80s. Light showers spun into southern Iowa by daybreak on Sunday (7^th) with unseasonably warm morning temperatures in the low 70s statewide.

Weekly precipitation totals ranged 0.03 inch in Sac City (Sac County) to 5.52 inches in Russell (Lucas County). The statewide weekly average precipitation was 1.17 inch; the normal is 1.18 inches. Several stations reported the week’s high temperature of 93 degrees on the 6^th, on average 15 degrees above normal. Elkader (Clayton County) reported the week’s low temperature of 41 degrees on the 3^rd, 11 degrees below normal.
