DES MOINES, Iowa – Severe weather is possible this evening into the overnight hours.

Meteorologist Megan Salois said temperatures Tuesday afternoon reached the lows 90s, with heat index values of nearly 100-degrees, and will help with thunderstorm development.

“The moist atmosphere in Central Iowa will lead to strong destabilization along a cold front in northwest Iowa,” Salois said. “Northern Iowa is where we will see the bulk of the thunderstorm activity this evening. So if you do have outdoor plans in the Ames and Des Moines Metros this evening, it will be hot but still should be dry.”

Salois said that it will not be until after midnight that the cold front will push further south and bring storms into the middle section of the state. The storms will be scattered through Central Iowa during the drive time into work on Wednesday. A few of these storms may still produce heavy rain, but the severe potential will not be as strong at that time.

Moisture will continue to feed in and along the front during the day on Wednesday, leading to on and off showers and storms through the day tomorrow. There could be some locally high amounts of rain near 2” or greater in few spots.

Much drier air with lower temperatures arrives on Thursday with some sunshine and highs back in the low 80s.
