It may be late March, but we are still talking winter weather across much of Iowa for tonight and tomorrow!
Most of us stay dry this morning, but scattered rain showers will quickly fill in this afternoon especially in northern and eastern Iowa. Today's highs will be in the mid to upper 40s. The precipitation becomes widespread tonight. Scattered showers and thunderstorms are expected across southwest Iowa. With cool air filtering into northeast Iowa, rain will transition to heavy snow.
A Winter Storm Warning has been issued for much of north central and east central Iowa from this evening through Saturday afternoon. A Winter Weather Advisory is in effect late this evening through 1 pm Saturday for Hamilton, Hardin, Humboldt, Jasper, Marshall, Poweshiek and Story Counties.
The rain/snow line should move south to Des Moines before sunrise Saturday morning. Light snow showers will continue for much of the morning before clearing to the east tomorrow afternoon. When it is all said and done, those in the warning area could receive 5-10" while those in the advisory are looking at anywhere from 1-5". Des Moines likely won't pick up more than an inch, and most of that won't stick to the roads.
Sunday looks dry, but more rain returns on Monday and Tuesday of next week. We could have the right setup for a few strong to severe thunderstorms, especially in southern Iowa. Temperatures throughout the extended forecast will mainly be in the 40s and 50s.
Have a good day!
