September began unseasonably cool and dry for the state with measurable but below-normal rainfall in northern Iowa; southern Iowa stations reported no measurable totals. Temperatures across eastern Iowa were up to eight degrees below normal through the reporting period with a statewide average temperature at 62.4 degrees, 6.3 degrees below normal.

Sunday (1st) afternoon was mostly sunny with northerly winds and high temperatures in the 70s. Winds became variable into Monday (2nd) morning with upper 40s and low 50s observed statewide under cloudless skies. A southerly shift in the wind helped bring temperatures back to the mid 70s with persisting clear conditions under a stable dome of high pressure. Patchy fog was observed in central Iowa around sunrise on Tuesday (3rd) with upper 40s reported in eastern Iowa; temperatures were several degrees warmer farther west where winds were more southerly. Afternoon highs rose into the upper 70s across much of the state as southerly winds increased in strength with gustier conditions in northwest Iowa. Overnight lows into Wednesday (4th) varied from the mid 50s northwest to upper 40s southeast. Daytime highs pushed into the low 80s in western Iowa in advance of a cold front moving southeast through the Upper Midwest; mid to upper 70s were observed in eastern Iowa.

Scattered showers and a few thunderstorms developed along the cold front as it entered northwest Iowa into the early morning hours of Thursday (5th).

Charles City (Floyd County) observed 0.39 inch while Northwood (Worth County) added an additional 0.22 inch at 7:00 am on Friday (6th) after an initial 1.12 inches was reported the previous morning.
