Heavy Rain Mid Week 9/21

Heavy Rain Possible Northwest Iowa

It was another beautiful day across the state. Highs climbed into the mid to upper 70’s, which is just a few degrees above normal. The main forecast concerns this evening will be the chance for fog across western Iowa, and light rain across northern Iowa. Any rain that does develop this evening will be very late, or near sunrise Tuesday. Not expecting a whole lot of rain, but just enough that a few places to the north may see wet pavement Tuesday morning. Fog may also develop this evening across western Iowa, which may reduce visibilities.

The attention then turns to the Wednesday and Thursday time frame as a decaying tropical system currently across the southwestern United States will be tracking off to the northeast. This will bring the potential for heavy rain across northwest Iowa, with the rest of the state remaining dry during this period. Rainfall totals over northwest Iowa are currently forecasted to range from a half an inch to an inch and a half.

Iowa 8 to 14 Day Temp OutlookIf you are enjoying this weather, the good news is it looks to stick around for the next two weeks. In the latest 8-14 day temperature outlook released by the Climate Prediction Center, there is a 70% probability that Iowa will see above average temperatures during this time frame. This would mean that above average temperatures will be with us through the first week in October. Looking ahead to the weekend, temperatures will be in the 70’s with full sun, so another chance to get outdoors and enjoy the weather!
