DES MOINES, Iowa — It has been a sad 24 hours of severe weather in the U.S., with many tornado fatalities across the Ohio Valley and surrounding areas. More severe weather is possible in Oklahoma and Texas Saturday.

Our weather has been quiet, cool, and breezy, with a welcome reappearance of the sun Saturday afternoon. Things get more interesting Sunday night, as your weather timeline shows.

Lows Saturday night will be chilly. It’s possible that valleys in the far northern tier of counties in Iowa could see patchy frost!

We’re at a marginal risk for storms late Sunday night in the WHO 13 viewing area. These look to move in after 11 p.m. and linger into the early morning hours on Monday.

Chances for severe weather increase in southern and parts of central Iowa late Monday, as shown in the images from the Storm Prediction Center and Colorado State University below. Enough energy will be present in the atmosphere late in the day in southern Iowa to fuel thunderstorms, with the main threat coming in the form of hail.

The slideshow below walks you through storm timing. Much-needed rain chances will be with us intermittently in the early morning hours on Thursday.

At this point, the hydrologists at the National Weather Service office in Johnston tell us the flooding potential across central Iowa is low after two weeks of mostly dry conditions. We’ll be here to monitor things, but yards, fields, and gardens should be happy! Highs for the next six days follow the European computer model’s rainfall prediction through Thursday morning.

Your WHO 13 7-day forecasts follow. We look to stay in this cooler regime through the end of May, as shown in the extended graphics below. I don’t put a lot of stock in monthly forecasts, but I thought I’d throw them in for you to look at. They show June being a bit warmer than average, with normal precipitation amounts expected.
