Storms Tonight with Heavy Rain and Hail

June 21, 2016

A warm front, southwest of Iowa early this afternoon, is forecast to move northeast across the state.

4

As it does, rain and storms will develop later this evening. The storms are expected to develop around 10 or 11 pm and become widespread in just a couple of hours. The initial storms could produce large hail and heavy rain. Then the threat turns to more of a flooding rain situation. Widespread 1-2″ of rain is expected with isolated higher amounts to near 5″. This is the reason why a Flash Flood Watch is in effect tonight.

Flash Flood Watch

Flash flood guidance shows the ground could only handle a little more than 2″ of rain in 3 hours. Some places might see more than that.

Here is the rain forecast for Tuesday evening to Wednesday evening. Most of this rain will fall tonight.

The storms will be widespread overnight and eventually ending between 7-9 AM Wednesday.
