Midweek severe weather

March will go out like a lion for some in the Midwest with the possibility of severe weather late Wednesday afternoon and evening.  It's not going to be a major factor for us, but for areas from Fairmont, MN down through Des Moines, IA and out towards Omaha and Lincoln, NE could experience strong thunderstorms producing hail and gusty winds late Wednesday.

Strong south winds will not only bring 70 and 80 degree weather up through the Plains and Midwest, but also an increase in moisture.  A strong low pressure system will pull a cold front through the central Plains Wednesday afternoon.  Ahead of the front, thunderstorms will be likely as they interact with a strong jet stream and low level jet overhead.  Those thunderstorms could form into a squall line and shift east overnight Wednesday. 

Scattered showers and thunderstorms will be possible for northern Illinois and southern Wisconsin after 10pm, but the severe threat will remain low for us.
