It was a hot week across Iowa with temperatures averaging 6.2 degrees above normal. The hottest weather came during the first one-half of the reporting week but temperatures stayed above normal everywhere and on every day for the remainder of the week. Temperatures across western/southwest Iowa averaged 8 to 10 degrees above normal with Little Sioux recording highs of 98 degrees or higher on four days. Eastern/northeastern sections were ‘only’ 4 to 6 degrees hotter than normal. Rainfall was infrequent but locally heavy. Thunderstorms were widely scattered across the northern two-thirds of the state on Monday (13th) with the bulk of the week’s rain falling on Tuesday (14th) when thunderstorms rumbled across all but far southwest and south central Iowa. Damaging winds were reported from 15 counties, mostly across the north, on Tuesday afternoon and evening with gusts to 73 mph measured at the Estherville Airport. Thunderstorms also occurred across far northwest Iowa and along the Nebraska border on Friday night into Saturday morning. These weekend storms brought widespread high winds to northwestern Iowa with 69 mph gusts at the Sioux City Airport and 68 mph at the Le Mars Airport. Weekly rain totals varied from none over much of southwest and south central Iowa to 5.46 inches near Nora Springs in Floyd County.
