Exceedingly wet conditions were reported across broad swaths of Iowa with numerous stations observing 400-600% of normal rainfall through the reporting period. Warm temperatures also persisted with positive departures in the six to nine degree range over southern Iowa; the statewide average temperature was 71.2 degrees, 5.5 degrees above normal.

Sluggish thunderstorms in northwestern Iowa expanded south and east into Sunday (6^th) afternoon, covering much of the state’s central one-third. Much of the complex dissipated into the evening hours, though another line of thunderstorms formed in western Iowa in the overnight hours of Monday (7^th). This line moved slowly into central Iowa and dissipated after noon. Much of western Iowa received at least 0.50 inch with multiple stations in west-central Iowa collecting 2.00 to 4.00 inches; Greenfield (Adair County) reported 3.02 inches with 4.18 inches in Corning (Adams County) and 4.79 inches in Guthrie Center (Guthrie County). Afternoon conditions were pleasant as clouds cleared with temperatures in the upper 70s and low 80s with southeasterly winds. Cloud cover increased over northwestern Iowa into the early hours of Tuesday (8^th) as a cold front entered the state. Showers and thunderstorms moved over northern Iowa throughout the day as the front sagged from the southwest to northeast. A stationary front farther south slowed the advance of the cold front, funneling anomalous atmospheric moisture from west-central to central Iowa. Training thunderstorms brought significant rainfall totals to numerous stations along with severe-warned thunderstorms, producing swaths of wind damage in Polk County. Numerous flash flood warnings were issued as the line slowly approached the Iowa-Missouri border by Wednesday (9^th) morning. Nearly 100 stations recorded at least 2.00 inches with nearly 20 stations above 4.00 inches in central Iowa; Clive (Dallas County) reported 4.10 inches with 5.21 inches in Norwalk (Warren County) and 5.87 inches in Des Moines (Polk County). The statewide average rainfall was 1.40 inches, more than 0.50 inch above the weekly 30-year climatological average. With full frontal passage through the daylight hours, temperatures held in the upper 70s and low 80s with light west-northwesterly winds and some lingering clouds over the state’s southern quarter.

Thursday (10^th) dawned clear with variable wind direction from west to east and a range of temperatures from low 50s north to mid 60s south. Afternoon highs rose nicely into the low 80s across the state with lower relative humidity and ample sunshine. Starry skies were visible into Friday (11^th) morning with morning lows in the 50s and a shift to a southerly wind direction. Daytime temperatures returned to the lower 80s as wind speeds increased northwest as a quick-moving cold front dropped through the state. Several stations observed rainfall from thundershowers that formed along the surface front after sunset with general totals under 0.20 inch; Westfield (Plymouth County) collected 0.51 inch from a more organized storm. Winds shifted to the northwest into Saturday (12^th) with pleasant daylight temperatures in the 70s under mostly sunny skies. Scattered showers developed across western Iowa after midnight with morning temperatures in the mid to upper 50s.

Weekly precipitation totals ranged from 0.23 inch in Nora Springs (Floyd County) to 7.76 inches in Guthrie Center. The statewide weekly average rainfall was 2.05 inches, more than double the normal of 0.84 inch. Shenandoah (Page County) reported the week’s high temperature of 100 degrees on the 8^th, 19 degrees above normal. Spencer Municipal Airport (Clay County) reported the week’s low temperature of 44 degrees on the 24^th, seven degrees below normal.

“The first week of September was one of the hottest on record, setting up some muggy conditions for attendees at the Farm Progress Show. As we headed into the Labor Day weekend, parts of northern Iowa received much-needed rainfall that will help chip away at longer-term soil moisture deficits,” Secretary Naig said. “Farmers are busy chopping silage and preparing for harvest as we wait for corn and soybeans to dry down and fully mature. We’re keeping an eye on the outlooks, which show more seasonal temperatures and better chances of rainfall as we move into mid-September.”

The weather headline for the reporting period was unseasonably hot temperatures, producing one of the warmest starts to September on record. Conditions across Iowa’s southern half were 12 to 15 degrees above normal with slightly cooler conditions north due to more cloud cover and rainfall. The statewide average temperature was 79.8 degrees, 11.1 degrees above normal.

Showers and a few thunderstorms continued across eastern Iowa into Sunday (30^th) afternoon. There was a broad range of afternoon temperatures, from the low 90s southwest to upper 70s northeast. Rain totals were generally between 0.25 to 0.50 inch with pockets of higher totals in the northeast; McGregor (Clayton County) observed 0.50 inch with 0.58 inch in Marion (Linn County). Winds shifted southwesterly overnight into Monday (31^st) with morning lows in the upper 60s to mid 70s north to south. A few scattered showers moved through Iowa during the late morning hours, though totals were light and isolated. Daytime conditions were mostly sunny with mid to upper 80s over northern Iowa and low to mid 90s across the southern part of Iowa. Overnight lows bottomed out in the upper 60s and low 70s with areas of fog due to light winds, clear skies and high dewpoints. Afternoon conditions on Tuesday (1^st) were similar to the previous day with winds turning easterly across western Iowa as a strong disturbance rode a strong ridge that was in place over the southern United States. Strong thunderstorms pushed into northwestern Iowa after sunset, with some cells becoming severe and tornado-warned; no tornadoes were observed but there were several strong wind gusts with a 81-mph reading in Hawarden (Sioux County) and 87-mph gust in Britt (Hancock County). Northwest stations collected the highest amounts with 1.00 inch in Orange City (Sioux County), 1.72 inches in Rock Rapids (Lyon County), and 2.00 inches in Le Mars (Plymouth County). Thunderstorms continued from north-central into eastern Iowa through much of Wednesday (2^nd) with daytime temperatures from the mid 80s north to upper 90s south. Northern Iowa received the most rain with 0.80 inch in Lake Mills (Winnebago County) to a 1.12-inch report in Lake Park (Dickinson County).

Scattered thunderstorms developed into Thursday (3^rd) from southwest to northeast Iowa with morning lows in the 70s and southerly winds. Rainfall dissipated by the late afternoon hours with general totals under a few tenths of an inch with higher totals in west-central Iowa; Schleswig (Crawford County) recorded 0.65 inch while 1.10 inches was observed in Sac City (Sac County). Clouds held from central to northeast Iowa through Friday (4^th) with isolated thunderstorms firing later in the day. Some of the storms were severe-warned along the Iowa-Wisconsin border where large hail and gusty winds were observed. Two stations in Allamakee County, Monona and Postville, observed 1.03 and 1.14 inches of rainfall, respectively. A complex of thunderstorms fired along an existing outflow boundary and moved into northwest Iowa before sunrise on Saturday (5^th). Several stations reported more than 1.00 inch of rainfall before the disturbance dissipated; Rock Rapids (Lyon County) had 1.60 inches with 1.88 inches in Massena (Cass County). Daytime conditions were quiet with upper 70s north to low 90s south under easterly winds. Compared to the last several mornings, Sunday (6^th) dawned with cooler temperatures, in the mid to upper 60s east, with mostly cloudy skies and widespread fog.

Weekly precipitation totals ranged from no measurable amounts at multiple southern stations to 3.05 inches in Sioux Center (Sioux County). The statewide weekly average rainfall was 0.37 inch, while the normal is 0.88 inch. Donnelson (Lee County) and Lamoni (Decatur County) reported the week’s high temperature of 100 degrees on the 1^st and 3^rd, respectively, on average eight degrees above normal.

Unseasonably dry conditions returned to the state with most stations reporting below normal rainfall. A shift to a more seasonal weather pattern brought near normal to slightly warmer conditions across Iowa through the reporting period; the statewide average temperature was 71.1 degrees, 0.5 degree above normal.

A complex of showers and few thunderstorms pushed across southern Iowa through Sunday (16^th) afternoon before dissipating in the evening hours. Daytime temperatures were in the upper 70s to low 80s with northerly winds and scattered cloud cover. Rain totals were generally a few tenths of an inch, though Keokuk Lock and Dam (Lee County) reported 0.64 inch while 0.75 inch was observed near Council Bluffs (Pottawattamie County). Foggy conditions developed over portions of the state on Monday (17^th) with morning lows from the mid to upper 50s north to low 60s south. Afternoon conditions were pleasant with highs in the upper 70s and low 80s with light winds and ample sunshine. Clouds increased over western Iowa into the early morning hours of Tuesday (18^th) as showers crossed into Iowa; moderate to heavy rain fell across the extreme southwest corner after sunrise with additional development in eastern Iowa. Isolated severe-warned storms also fired across portions of northern and eastern Iowa later in the afternoon through sunset along with heavier showers in the southeast. Overall rain totals were highest in the southern corners, with 1.35 inches in Sidney (Fremont County) to 1.47 inches in Augusta (Lee County). Many southern stations observing rainfall also registered amounts in the 0.25- to 0.75-inch range. Wind shifted northerly overnight as a stationary front held across southern Iowa. Another round of stronger thunderstorms moved into southwestern Iowa on Wednesday (19^th) morning with thunderstorms firing east to west along the surface boundary through the day; a weak land spout was observed near Marsh (Louisa County) later in the afternoon. Daytime temperatures held in the 70s statewide as clouds cleared and winds shifted northeasterly.

Thursday (20^th) was a mostly sunny day for much of the state with stronger southerly winds in western Iowa. Highs stayed in the low 80s with a few showers moving through northeastern Iowa by nighttime. Friday (21^st) dawned with temperatures in the 60s, light southerly winds and partly cloudy skies east and foggy conditions west. Conditions warmed into the mid 80s with higher dewpoints and more unstable air in eastern Iowa. A narrow line of thunderstorms, some severe warned, developed later in the afternoon. Several stations registered higher totals from 0.51 inch in Le Claire (Scott County) to 0.62 inch in Camanche (Clinton County). Fog was reported over northern Iowa on Saturday (22^nd) morning with morning temperatures ranging from the mid 50s northwest to mid 60s southeast. Winds swung back around northerly as a cold front cleared the state; daytime temperatures were in the upper 70s to low 80s north to south. Starry skies persisted into Sunday (23^rd) morning with lows in the 50s.

Weather summary

A large dome of high pressure over the southern United States set up a “Ring of Fire” pattern over Iowa. This atmospheric configuration channeled several waves of thunderstorms, some severe, through Iowa. Rainfall was widespread and well-above average over swaths of the state, leading to the wettest week of the growing season. Conditions were also unseasonably warm with a statewide average temperature of 76.7 degrees, 4.8 degrees above normal.

Thundershowers pushed out of eastern Iowa on Sunday (9^th) afternoon as skies cleared across western Iowa, where temperatures rose into the upper 70s and low 80s. Winds shifted to a northeasterly direction overnight into Monday (10^th) with morning lows varying from the upper 60s north to mid 70s south and patchy fog. Clouds developed over northern Iowa into the afternoon hours, holding daytime highs in the lower 80s; sunshine and southerly wind pushed temperatures into the upper 80s and low 90s farther south. A stationary front draped west to east over Iowa was a focusing mechanism for stronger storms that formed after midnight and expanded across northern Iowa into Tuesday (11^th) morning. Scattered cells consolidated in eastern Iowa, where a squall line developed as a rear-inflow jet began strengthening the mesoscale convective system (MCS). A wind gust of 75 mph in Independence (Buchanan County) was the beginning of what would later be classified as a derecho; the line pushed several hundred miles through the Ohio Valley and dissipated in Virginia. Along with very heavy rain and severe wind gusts in eastern Iowa, two EF-1 tornadoes spun up near Greeley (Delaware County), causing damage to vegetation and outbuildings. Many gauges in eastern Iowa reported at least 0.50 inch with nearly 50 stations at or above 1.00 inch; North Liberty (Johnson County) and Belle Plaine (Benton County) observed the highest totals of 2.33 and 2.48 inches, respectively. Another line of severe thunderstorms pushed into western Iowa by sunrise on Wednesday (12^th) taking a similar but more southerly path through the state. A secondary complex of strong thunderstorms formed in east-central Iowa and sped out of the state by the early afternoon as the disturbance farther west lost energy. Late day conditions were muggy with high dewpoints and temperatures in the upper 80s and low 90s in western Iowa along with ample instability.

A nearly mirror-image MCS with a broader precipitation shield accelerated into Iowa early on Thursday (13^th). The entire complex spanned much of the state with several severe and tornado-warned storms in western and central Iowa; no tornadoes were observed. The southern extent of the squall line dove into southeastern Iowa, producing strong wind gusts and isolated, torrential downpours. The systems exited the state by around noon with clearing conditions in Des Moines (Polk County) for the opening day of the Iowa State Fair. Rain totals for the preceding 36 hours were heaviest from central to western Iowa and then pockets in eastern Iowa; nearly 50 stations collected 2.00 or more inches with 3.05 inches in Gilbert (Story County) to 4.31 inches in Schleswig (Crawford County) and statewide average of 0.90 inch. Winds shifted easterly through the evening and nighttime hours with an ample atmospheric moisture supply for thunderstorms to reform along a surface boundary in west-central Iowa after midnight. Storms expanded west and east, producing multiple flash flood warnings due to heavy rainfall from training storms, as the complex expanded into northern Iowa. The heaviest rainfall dissipated by late Friday (14^th) morning with showers persisting through the day under overcast skies. Daytime temperatures were unseasonably cool, holding in the low to mid 70s across much of Iowa. In addition, 20 stations reported the heaviest totals at 7:00 am on Saturday (15^th) from 3.06 inches in Pella (Marion County), 5.01 inches in Norwalk (Warren County) to 5.31 inches in Wapello (Louisa County). Stations north and south of this swath had general totals of 0.50 to 1.00 inch with a statewide average of 1.03 inches. Showers persisted over southern Iowa before falling apart. Temperatures rose into the upper 70s and low 80s with variable winds and a low-level stratus deck. Scattered showers and a few thunderstorms formed ahead of a cold front transiting the state into the evening hours, with stronger storms in the southeast corner. Twenty-five southeastern stations observed the highest totals, from 1.84 inches in Mount Union (Henry County), 3.05 inches at Burlington (Des Moines County) to 3.49 inches in Fort Madison (Lee County). Sunday (16^th) dawned with foggy conditions, light northwesterly winds and morning temperatures in the upper 60s north to low 70s south.

Weekly rain totals ranged from 0.36 inch in New Market (Taylor County) to 9.45 inches in Wapello. The statewide weekly average rainfall was 2.60 inches, nearly triple the normal of 0.88 inch. Lamoni (Decatur County) reported the week’s high temperature of 95 degrees on the 11^th, nine degrees above normal. Greenfield (Adair County) reported the week’s low temperature of 48 degrees on the 12^th, 15 degrees below normal.

Several rounds of showers and thunderstorms brought well-above normal rainfall across portions of the state. All modes of severe weather were also reported, particularly in eastern Iowa. Cloud cover, rainfall and wildfire smoke held temperatures below to near-normal from west to east across Iowa; the statewide average temperature was 74.5 degrees, 0.4 degrees above normal.

Variable winds and mostly sunny skies prevailed through Sunday (2^nd) afternoon with highs in the lower 80s. Winds turned southerly into Monday (3^rd) morning with dense fog over portions of southern Iowa with lows in the 60s. Southerly winds increased throughout the day as a cold front approached from the west. Daytime temperatures held in the low 80s with passing clouds and some haze. Showers and a few thunderstorms moved into western Iowa after midnight and continued across the state through Tuesday (4^th). The front slowed as a low pressure center over Missouri intensified, shifting more moisture into southwestern Iowa. After midnight, two areas of moderate rainfall were found in the southeast corner along with more development farther west; this complex intensified as embedded thunderstorms became severe-warned with large hail and strong wind gusts. Under cloud cover and rainfall, morning lows on Wednesday (5^th) held in the mid to upper 60s with upper 50s over northern Iowa. Thunderstorms continued from central Iowa into the southeastern reaches of the state until the system fully exited by Wednesday (5^th) afternoon. Continuous rainfall over southern Iowa led to some flash flood warnings along with more than a month’s worth of rainfall; Seymour (Wayne County) collected 4.26 inches with 4.63 inches in Creston (Union County) and 5.72 inches in Murray (Clarke County). Over 150 stations observed at least 1.00 inch with more than 50 receiving at least double that amount and a statewide average of 0.96 inch. Light easterly winds developed overnight into Thursday (6^th) with widespread fog and temperatures from the low 50s northwest to upper 60s south east. Afternoon conditions were partly cloudy with pleasant temperatures in the mid to upper 70s and light southerly winds.

Friday (7^th) was an active severe weather day across the state with widespread fog and heavy dew starting the day as temperatures held in the mid to upper 60s. Ample low-level moisture and atmospheric instability ahead of a strong cold front were ideal ingredients for a complex of severe thunderstorms from north-central through eastern Iowa. The most significant event was a longer track EF-2 tornado near Fairbanks (Buchanan County) along with an EF-1 in Prairieburg (Linn County).  The remains of the complex lost energy and pushed out of southeast Iowa just before midnight. Rainfall totals reported at 7:00 am on Saturday (8^th) were highest from east-central to northeast Iowa; Mason City (Cerro Gordo County) observed 2.21 inches while Nashua (Floyd County) hit 2.24 inches. There were also a swath of stations into southeastern Iowa that had widespread totals from 0.75 to 1.00 inch. A warm front pushing north into Iowa was a focusing mechanism for additional thunderstorm development into Sunday (9^th) morning. A slow moving cell brought heavier downpours over Fort Dodge (Webster County) where four stations reported between 2.00 and 2.38 inches. A broad swath from north-central into southwest Iowa also received general totals in the 0.75-1.50 inch range. Morning temperatures were in the upper 60s northeast to upper 70s southwest.

Weekly rain totals ranged from 0.04 inch near Dubuque (Dubuque County) to 5.77 inches in Murray (Clarke County). The statewide weekly average rainfall was 1.87 inch; the normal is 0.88 inch. Des Moines International Airport (Polk County) reported the week’s high temperature of 91 degrees on the 9^th, seven degrees above normal. Spencer Municipal Airport (Clay County) reported the week’s low temperature of 47 degrees on the 8^th, 14 degrees below normal.
