Severe weather was the headline through the reporting period with several rounds of thunderstorms producing all modes of hazardous weather, including large hail, flash flooding and several tornadoes. This was also the third consecutive week of above-normal rainfall for much of Iowa. Temperatures were well above average with positive departures approaching 14 degrees from central to southeast Iowa; the statewide average temperature was 60.3 degrees, 11.4 degrees above normal.

Showers streamed across Iowa’s eastern half through Sunday (12^th) afternoon while sunny skies and gusty southerly winds held over northwestern Iowa. Rainfall was highest along a narrow south-central to northeast band with 0.69 inch at Rathbun Dam (Appanoose County) to 0.95 inch in Peosta (Dubuque County); general totals where rain fell were in the 0.20- to 0.40-inch range. The first of four severe weather days occurred across northern Iowa on Monday (13^th) as a low pressure center transited the Iowa-Minnesota border. Afternoon temperatures pushed into the upper 70s in the presence of ample low-level moisture and wind shear. A few weak tornadoes developed later in the evening along with pockets of large hail and locally heavy rainfall; Ringsted (Emmet County) registered 0.97 inch while Lake Mills (Winnebago County) collected 1.42 inches. Tuesday (14^th) dawned unseasonably warm in southern and eastern Iowa where morning air temperatures and dewpoints were in the low to mid 60s. A secondary low pressure center pushed through central Iowa as the attendant cold front clashed with warm, unstable air to the east, firing strong to severe thunderstorms. The storms raced east into the evening hours, producing two EF-1 tornadoes in Masonville (Buchanan County) and Dubuque (Dubuque County). Large hail was also widespread in eastern Iowa with a 3.5-inch hailstorm reported in Elma (Howard County). Stronger storms training over the same locations also produced very heavy rainfall; six stations hit 2.00 inches or more with 2.45 inches in Hartford (Warren County) and 2.78 inches in Sully (Jasper County). Much of Iowa’s southeastern two-thirds reported totals of a few tenths of an inch with a statewide average of 0.51 inch.

Severe weather on Wednesday (15^th) was dominated by large hail across much of southern Iowa along with isolated straight-line wind reports in the southeast corner.  Significant rainfall occurred at more than 30 stations where at least 1.00 inch was observed. Many locations in eastern Iowa picked up more than 0.75 inch with multiple tenths of inch farther west. The statewide average rainfall was 0.55 inch with the highest total of 1.93 inches in Vinton (Benton County). Thursday (16^th) was a pleasant day with morning lows in the upper 40s and low 50s under clear skies with a light westerly wind. Winds turned southerly into the afternoon hours, boosting highs into the upper 70s southeast to mid 80s northwest. Clouds increased overnight into Friday (17^th) as a strong low pressure center pushed into northwest Iowa. A cold front rapidly moved through western Iowa as instability, wind shear and moisture ramped up from central to eastern Iowa. Initial discrete supercells fired in eastern Iowa, well ahead of the surface boundary. Frontal-based thunderstorms were able to overcome the low-level cap and rapidly intensify just east of Des Moines (Polk County). Thunderstorms merged along the front as several became severe and tornado warned. Washington (Washington County) reported structural damage to farm buildings from a tornado. Straight-line winds became the dominate severe weather mode as the front moved closer to the Mississippi River; Cascade (Dubuque County) measured an 86 mph wind gust. Moderate to heavy rainfall was widespread in eastern Iowa with 1.02 inches in Ottumwa (Wapello County) and 2.35 inches in Wayne County. Saturday (18^th) into Sunday (19^th) was much less active with partly cloudy skies and much cooler temperatures.

Weekly precipitation totals ranged from no accumulation in Rock Rapids (Lyon County) to 4.34 inches at Bellevue Lock and Dam (Jackson County). The statewide weekly average precipitation was 1.27 inches; the normal is 0.87 inch. Lamoni (Decatur County) reported the week’s high temperature of 89 degrees on the 15^th, 26 degrees above normal. Lake Park (Dickinson County) reported the week’s low temperature of 23 degrees on the 18^th, 12 degrees below normal. Four-inch soil temperatures varied from the upper 40s north to mid 50s south as of Sunday.

The first reporting period of the season was unseasonably warm and wet as an active storm track brought several rounds of showers and thunderstorms, some severe, across Iowa. Temperatures were generally several degrees above average with the warmest conditions over southern Iowa; the statewide average temperature was 48.0 degrees, 4.4 degrees above normal.

Gusty southerly winds helped boost Sunday (29th) afternoon highs into the upper 60s and low 70s with generally clear conditions. Overnight lows at sunrise on Monday (30th) held in the upper 30s northwest to mid 50s southeast. Daytime conditions were well above average with temperatures from the mid 80s to low 90s with blustery winds out of the south; the statewide average temperature was 84 degrees, 30 degrees above normal. Scattered thunderstorms formed from central to eastern Iowa through the evening hours, bringing locally heavy rain, vivid lightning, and small hail. Cedar Rapids (Linn County) reported 0.71 inch, while 1.52 inches were observed in Dallas Center (Dallas County). Tuesday (31ˢᵗ) morning thunderstorms moved out of eastern Iowa as a cold front passed through the state. Wind speeds increased and shifted to a northerly direction, with afternoon conditions varying from the 50s in the north to the upper 60s in the south under mostly sunny skies. Showers moved into southern Iowa after midnight on Wednesday (1ˢᵗ), followed by a brief lull into the late morning hours. Winds also shifted to an easterly direction as a large-scale low-pressure system approached the state. Moderate rainfall became more widespread through the nighttime hours and overnight, with nearly 120 stations observing at least one inch. The highest totals were found across northwest, central and southeastern Iowa; Le Mars (Plymouth County) collected 1.50 inches, Ames (Story County) recorded 1.87 inches, and Earlville (Delaware County) recorded 1.95 inches; the statewide average was 0.86 inch, over 130% of the normal weekly total.

Thursday (2nd) was an active severe weather day for portions of southern and eastern Iowa as a warm front became a focusing mechanism for severe thunderstorms. Afternoon temperatures pushed into the low 70s with dew points in the mid 60s, providing enough instability for all modes of severe weather. Three-inch diameter hail was reported in Martinsburg (Keokuk County) along with an EF-1 tornado with winds approaching 105 mph near Welton (Clinton County). Moderate to heavy rainfall was again reported at many stations with the highest totals in north-central, northeast and a swath of southeast Iowa: New Hampton (Chickasaw County) registered 1.01 inches while Wellman (Washington County) observed 1.57 inches; the statewide average was 0.70 inch. Winds swung back to northerly as the cold front crossed Iowa with morning lows on Friday (3rd) near freezing north to the low 40s south. Another low pressure center moved across the Iowa-Missouri border through the day, producing some morning thundershowers and then some stronger storms in the southwest, ahead of the low’s triple-point. Large hail was observed in southwestern Iowa, but the ingredients for a bigger severe weather outbreak did not come together. Thunderstorms streamed into northern and eastern Iowa as another cold front swept through Iowa. Rainfall totals reported at 7 a.m. on Saturday (4th) were exceedingly high within a west-central to northern swath with 1.98 inches in Boone (Boone County) to 4.60 inches in Decorah (Winneshiek County); more than 70 stations observed at least an inch. Afternoon conditions were chilly with a brisk westerly wind and highs in the low 40s under cloud cover. Sunday (5th) dawned with most stations in the upper 20s and low 30s.

Weekly precipitation totals ranged from 0.55 inch in Rock Rapids (Lyon County) to 6.43 inches in Decorah. The statewide weekly average precipitation was 2.31 inches; the normal is 0.65 inch. Clarinda (Page County) reported the week’s high temperature of 91 degrees on the 30th, 33 degrees above normal. Sioux City (Woodbury County) reported the week’s low temperature of 24 degrees on the 30th, six degrees.

Unseasonable warmth persisted through the final reporting period of the season with temperatures approaching eight degrees above normal in northwestern Iowa; the statewide average temperature was 43.8 degrees, 6.1 degrees above normal. Most Iowa stations reported measurable rainfall with locations across northern Iowa registering slightly above average wetness.

Cloud cover dotted the skies over western Iowa through Sunday (16ᵗʰ) afternoon with light, variable winds and temperatures in the mid 40s north to low 50s south. Monday (17ᵗʰ) dawned with light easterly winds and clear skies over most of the state, with morning temperatures holding in the upper 30s and low 40s. Southeasterly winds became gusty through the daytime hours as a low pressure center moved from Kansas into Missouri. Rain showers formed ahead of the system across western Iowa into the evening hours as spotty thundershowers popped up in north-central Iowa. Showers increased in coverage over much of Iowa’s northern two-thirds into Tuesday (18ᵗʰ) morning, with moderate rainfall observed in northern and eastern Iowa. Dewitt (Clinton County) observed 0.75 inch, with 1.00 inch in Webster City (Hamilton County) and 1.03 inches in Fort Dodge (Webster County). Widespread totals south and west were in the 0.20–0.50 inch range, with less than a tenth of an inch over southern Iowa. Overcast conditions continued through the rest of the day, with highs varying from the upper 30s over northern Iowa to low 50s along the Iowa-Missouri border.

Winds shifted back to an easterly direction overnight into Wednesday (19ᵗʰ), with extremely dense fog observed statewide at sunrise. Morning lows did not retreat appreciably from the previous day’s temperatures, aided by thick stratus above the fog bank. With increased surface heating from the rising sun, low-level atmospheric mixing helped dissipate the fog through the afternoon hours, though redevelopment occurred into the evening. Daytime conditions remained cloudy, with temperatures in the 40s and light southerly winds. Foggy conditions returned on Thursday (20ᵗʰ) morning, with temperatures in the mid to upper 30s west to mid 40s east. Afternoon conditions remained cloudy across the state, with fog lingering and temperatures four to six degrees warmer than the morning minimums. Stars were finally visible over northern Iowa into Friday (21ᵗʰ), where temperatures dropped into the upper 20s and low 30s with light northerly winds; farther south, stubborn cloud cover persisted. Spotty showers developed across southern Iowa through the day as a surface boundary lifted north from Missouri. Rain totals were generally light, from 0.20 inch in Numa (Appanoose County) to 0.26 inch in Randolph (Fremont County). Morning conditions were overcast and foggy in northeastern Iowa on Saturday (22ⁿᵈ), with fog extending into south-central Iowa under clear skies. Overall temperatures were in the upper 20s and low 30s but warmed into the mid 50s to low 60s by the afternoon hours with gusty westerly winds prior to sunset. Clear skies were reported at sunrise on Sunday (23ʳᵈ), with patchy frozen fog and lows ranging from the mid 20s in northwest Iowa to low 30s farther southeast.

Weekly precipitation totals ranged from no accumulation at multiple stations in southern and northwest Iowa to 1.03 inches in Fort Dodge. The statewide weekly average precipitation was 0.20 inch, while the normal is 0.43 inch. Multiple stations reported the week’s high temperature of 59 degrees on the 17ᵗʰ, on average 12 degrees above normal. Several stations recorded the week’s low temperature of 22 degrees on the 22nd and 23rd, on average two degrees below normal.

September’s last full reporting period continued the recent unseasonably warm streak, with temperatures approaching 10 degrees above normal in northwestern Iowa. The statewide average temperature was 67.5 degrees, 8.1 degrees above normal. Rainfall was also below normal at most of Iowa’s reporting stations, with widespread departures of 0.50–0.75 inch.

Light showers dissipated across southwestern Iowa by Sunday (21ˢᵗ) afternoon as daytime highs rose into the upper 70s and low 80s under southerly winds. A few severe-warned thunderstorms developed over northwestern Iowa after sunset, though they dissipated within a few hours. Several stations reported moderate rainfall totals, including 0.44 inch in Ireton (Sioux County). Additional thunderstorms formed along the northeastern portion of the Iowa–Minnesota border by sunrise on Monday (22ⁿᵈ), with Decorah (Winneshiek County) receiving 0.48 inch. A west-to-east oriented surface boundary shifted south through the day as highs reached the mid 80s with persistent southerly flow. By the late afternoon, sufficient instability had materialized along the front over northern Iowa, allowing strong thunderstorms to develop. There were several reports of one-inch hail, with hailstones up to two inches observed in Sutherland (O’Brien County). Individual cells merged into a line that slowly moved into central Iowa as additional storms formed in west-central Iowa. Although the line weakened as it advanced into southern Iowa, moderate rain showers continued into Tuesday (23ʳᵈ) morning. More than 30 stations recorded at least an inch of rainfall, with the highest totals in pockets of northeastern Iowa and from west-central to southwestern Iowa. A gauge in Dubuque (Dubuque County) measured 2.13 inches, while 2.22 inches fell in Jefferson (Greene County). Outside of these amounts, much of the state’s southeastern half recorded between 0.20 and 0.60 inch.

“Last week, many areas of the state received several rounds of rain, which tapped the brakes on fall field work. Upcoming forecasts show a switch back to warmer and drier conditions through the end of September. Farmers who have corn and soybeans ready to go will likely take full advantage of that window to make progress on harvest,” Secretary Naig said. “I also want to remind all Iowans that this is National Farm Safety and Health Week. Whether you’re on the road, in the field or working around the farm, please keep safety top of mind. Farming comes with long, stressful days and real economic challenges right now. I encourage everybody to take care of their mental health and check in on their family members and neighbors, too.”

A nearly stationary cut-off low pressure system spun over the Upper Midwest throughout the reporting period, bringing above-normal rainfall to much of Iowa’s western three-quarters. Unseasonal warmth also persisted, with positive departures in the 10- to 12-degree range in eastern and southern Iowa. The statewide average temperature was 71.6 degrees, 8.6 degrees above normal.

Sunday (14ᵗʰ) afternoon was the warmest of the reporting period, with daytime highs in the mid-80s to low 90s under sunny skies; the statewide average high was 90 degrees, 14 degrees above normal. Scattered thunderstorms developed over central Iowa into Monday (15ᵗʰ) morning and continued into northeastern Iowa during the day. Temperatures rebounded into the upper 80s, with some locations in the southeast reaching the 90s. Additional storms formed in eastern Iowa toward evening before dissipating around sunset. Eastern Iowa recorded the highest totals: 1.98 inches in Sigourney (Keokuk County) and 1.99 inches in Mount Auburn (Benton County). Outside of these amounts, a broad swath of 0.25-to-0.75-inch totals extended from east-central to northeast Iowa. Winds shifted southeasterly into Tuesday (16ᵗʰ), bringing mostly clear skies and morning lows in the mid to upper 60s. Pulse thunderstorms developed intermittently throughout the day as the cut-off low pressure system provided energy and instability. With little steering flow, some storms in central and northern Iowa produced locally heavy rainfall and hail. Totals ranged from 2.13 inches in Burt (Kossuth County) to 4.25 inches in Fort Dodge (Webster County). Much of west-central Iowa received at least 0.75 inch, with another pocket of heavier rainfall in northeastern Iowa. Showers and thunderstorms persisted in western and northern Iowa into Wednesday (17ᵗʰ) morning, then shifted into central and eastern Iowa after noon. Temperatures varied widely, from the low 70s northwest to the low 90s southeast. Some storms were severe warned for hail and strong winds. The complex weakened as daytime heating ended, dissipating by nighttime. Four stations reported nearly half of their monthly rainfall in a single day, with totals from 2.01 inches in Carlisle (Warren County) to 2.37 inches in Eagle Grove (Wright County).

Thursday (18ᵗʰ) began with widespread, locally dense fog produced by warm surface temperatures, ample low-level moisture, and light winds. With the existing unsettled pattern, showers and a few thunderstorms continued across much of the state, though many stations reported lighter totals. In Jefferson (Greene County), two gauges measured 1.54 to 2.10 inches, while in Marshalltown (Marshall County), two additional gauges collected 1.30 to 1.39 inches. Many other stations reported between 0.10 and 0.40 inch, and the statewide average was 0.21 inch. Overcast skies persisted into early Friday (19ᵗʰ) as the stubborn low center over the Dakotas streamed showers into Iowa, particularly in the afternoon and evening. Light to moderate rain continued across southern Iowa through the morning of Saturday (20ᵗʰ) and lasted much of the day. Afternoon temperatures were pleasant, in the upper 60s to low 70s, though sunshine was limited. Southeastern Iowa recorded the heaviest rainfall at 7:00 a.m. on Sunday (21ˢᵗ), with amounts ranging from 1.00 inch at Mount Ayr (Ringgold County) to 2.30 inches in Milton (Davis County).
