Weather Summary
By: Justin Glisan, Ph.D., State Climatologist - 09/14/2021

After a stretch of wetter than normal weeks, unseasonably dry conditions returned to Iowa over the reporting period; only a handful of stations observed measurable rainfall, though these totals were well below normal. Generally warmer temperatures were also felt across much of the state with positive departures over three degrees observed across southern Iowa. The statewide average temperature was 68.5 degrees, 1.2 degrees above normal.

Winds switched to a westerly direction through the afternoon on Sunday (5th) as highs remained comfortably in the low 80s statewide. Very spotty showers popped up over northwestern Iowa but dissipated by the evening hours; several stations reported very light rainfall with a trace observed near Eagle Grove (Wright County) to 0.22 inch at two gauges in Lyon County. Overnight lows into Monday (6th) ranged from isolated upper 40s northwest to upper 50s southeast with spotty dense fog observed at multiple stations. Southerly winds and sunny skies throughout the day pushed temperatures into the mid to upper 80s. Conditions remained clear and unseasonably warm through early morning with lows in the upper 60s; Guthrie Center (Guthrie County) reported a low of 71 degrees, 17 degrees above average. Upper-level wild fire smoke led to hazy conditions after sunrise on Tuesday (7th) as a cold front approached Iowa's northwest corner. The front moved through central Iowa by noon, shifting winds to a northerly direction and clearing the sky of lingering smoke. As the front moved out of southeastern Iowa, isolated thundershowers formed along the Iowa-Illinois border but did not produce measurable rainfall. Behind the cold front temperatures dropped into the low to mid 50s under starry skies. Gusty northwesterly winds built in on Wednesday (8th) under brilliant sunny skies as very pleasant conditions and high pressure dominated the Upper Midwest. Daytime highs reached into the 70s with cirrocumulus clouds pushing though eastern Iowa.

Overnight lows into Thursday (9th) were chilly in northwestern Iowa, where low 40s were reported. The rest of Iowa experienced clear skies and lows in the upper 40s to low 50s southeast; the statewide average low was 49 degrees, five degrees below normal. Another comfortable day was in store for Iowa as afternoon highs remained in the mid to upper 70s with light, variable winds and generally clear skies; partly sunny skies were observed in eastern Iowa as a large low pressure center north of the Great Lakes spun cumulus clouds into the region. Under light southeasterly winds, overnight lows into Friday (10th) stayed warmer than the previous morning, spanning the mid 50s east to low 60s southwest. An end-of-week heat-up began during the afternoon as southerly winds and sunshine boosted highs into the mid to upper 80s. Saturday (11th) morning temperatures stayed in the upper 50s and low 60s with patchy fog at some stations. A weaker low pressure system began transiting the state though the afternoon hours as temperatures rose into upper 80s and low 90s; the statewide average high was 88 degrees, 11 degrees above normal. Light showers formed along the low's attendant cold front with totals reported at 7:00 am on Sunday (12th) ranging from 0.01 inch at multiple northwestern Iowa stations to 0.05 inch at Rock Rapids (Lyon County).

Weekly precipitation totals ranged from no accumulation at a majority of stations to 0.22 inch near Lester and Rock Rapids (Lyon County). The statewide weekly average precipitation was 0.01 inch while the normal is 0.83 inch. Perry (Dallas County) observed the week's high temperature of 93 degrees on the 11th, 15 degrees above normal. Battle Creek (Ida County) and Spencer Municipal Airport (Clay County) reported the week's low temperature of 44 degrees on the 9th, on average eight degrees below normal.
