It’s been a rainy stretch of weather across eastern Iowa in the past week. With more heavy rain on the way, there is a threat for flash flooding across much of the area. The map below shows how much rain the ground can handle within a 3 hour period before flash flooding occurs. Much of the area can only handle an inch and a half to 2 inches.
Here is how much rain the WPC is forecasting for the area. This is through tonight, and the bullseye of just over 3 1/2 inches across eastern Iowa. Keep in mind, thunderstorms with heavier rain could drop heavier amounts within a short period of time.
With the heavy rain potential, a Flash Flood Watch goes into effect at 4 PM Wednesday, and lasts through Thursday morning for much of the KWWL viewing area.
Here’s a check of Storm Track 7 Live Doppler Radar (~2PM). It’s showing some strong thunderstorms with heavy rain tracking east through the area.
Right now, these storms are below severe limits. Later this afternoon and evening that we need to keep an eye out for severe weather as a warm front tracks through the area. We’ll keep an eye on it and break in on KWWL if need be.
