A strong late winter storm system will affect much of northern Iowa Wednesday into Thursday. This storm system will bring a variety of weather to the state through Thursday. A strong storm system will lift out of the southwest U.S. and across southern Iowa Wednesday through Thursday. Colder air will move in behind the system beginning across northern Iowa Wednesday afternoon through all of Iowa by Thursday morning. The storm may bring heavy snow to portions of northern Iowa, especially along the Minnesota border and thunderstorms, some of which may be strong to southern Iowa.
A winter storm watch is in effect from Wednesday morning through Thursday. Rain will transition to snow Wednesday morning. Moderate to heavy snow will be possible Wednesday afternoon and evening. Snowfall accumulations of 4 to 8 inches of snow with isolated higher amount are possible.
Strong northeasterly winds between 25 and 35-mph gusting as high as 45-mph will be possible Wednesday morning and continuing into Wednesday evening. Visibility within areas of snow may be reduced under one half mile Wednesday. Significant impacts to travel will be possible for the Wednesday evening commute and through Thursday due to snow. Some power outages will be possible Wednesday night through Thursday due to heavy wet snow and gusty northeast winds.
There remains some uncertainty in the track of this spring storm and the narrow corridor of heavy snow that may be possible within it. Any shift in the storm track may change the location of heavy snow.
Across southern Iowa, the chance for severe weather exists Wednesday afternoon. Because of this, the statewide tornado drill scheduled for Wednesday morning has been postponed until Thursday. Strong to severe storms, with the possibility of a tornado or two can not be ruled out across southwest and south central Iowa.
