So far this week, temperatures have been more summer like as highs have been in the 80’s. Strong south winds have been helping drive our temperatures up, however, change is on the way. A low pressure system will be passing to our north across Minnesota during the day Thursday. Extending to the south from this low, will be a cold front.
Thursday will be a partly sunny day, with temperatures warming back up into the 80’s. As the cold front begins to sag into the state, storms will begin to develop across north central Iowa, with storm development likely after 5pm. Storms will continue to develop to the south along the cold front as the night goes on. A few of these storms may be severe, with damaging winds and large hail the primary threat.
This front will stall out across southern Iowa Thursday evening, which will be the focus point for additional thunderstorms on Friday. Right now there are a lot of questions around the severity of storms on Friday, but heavy rains will be likely. Where this front stalls out, will be where the heaviest rainfall totals will add up. After the rain moves out of the state late Friday, average temperatures move back into the state by Saturday.
