First Days of August Forecast

Only one more day remains of July, then we hit the month of August; which often features some of the warmest temperatures of the year. By the looks of the forecast, it is likely that we come into the month with temperatures in the 90s and a chance of thunderstorms as well...

Tonight will remain dry with lows in the lower to mid 60s from east to west across the state. Expect clear skies once again on Tuesday, with temperatures rising a couple more degrees; highs in the upper 80s to low 90s throughout. Moisture will begin to work its' way in as well on Tuesday, which will only allow the nighttime temperatures to drop into the mid to upper 60s from east to west across the state.

Wednesday will bring the first slight chances of afternoon thunderstorms in the picture for western Iowa. Highs during the afternoon should reach into the lower 90s across much of the state. Expect thunderstorms to develop during the evening hours in areas of SD/NE/MN along a frontal boundary; these storms should move into northwestern Iowa during the nighttime hours and may also affect other portions of the northwestern half of the state by sunrise. Lows during the night should remain in the mid to upper 60s.

The speed of the system moving through will play an important role in any thunderstorm chances on Thursday, currently only slight chances across the state during the day and into the nighttime hours. Highs on Thursday won't change much, upper 80s to lower 90s from northwest to southeast. Lows from the mid 60s in the northwest to near 70 in the southeast where the best chances of rain remain in the forecast.

We'll finish off the week with another nice day, but another fast moving storm system on the horizon. Some showers/thunderstorms may be possible, especially across northern Iowa on Friday night. Highs in the upper 80s & lower 90s; lows in the mid to upper 60s. The weekend comes in with plenty of questions for the forecast, mainly in terms of precipitation as we seemingly enter a regime of isolated thunderstorms/showers across the state. Still plenty warm and somewhat humid throughout the weekend, although those isolated storms may play with some of the weekend plans.
