ORIGINAL POST: Saturday morning’s extensive cloud cover, which limited the heating and energy from the sun—one of the components for stronger thunderstorms—has helped to lower our already small severe weather threat.
Minimal-to-Low Severe Risk
With the cold front pushing its way across the Mississippi River accompanied by light showers, the best chance for strong-to-severe weather appears to be focused east of Interstate 39. This is great news, considering this system produced tornadoes in Iowa on Friday. I’ve lowered our Threatrack to Level 1 west of I-39 and kept it at Level 2 east of I-39, where a few storms from central Illinois could brush our eastern coverage area.

Until the cold front passes, pop-up showers and thunderstorms will contain heavy downpours with potentially small hail. An isolated stronger storm may also contain gusty wind. By dinnertime, the front should be east of our area. Keep it tuned to the weather blog for more updates as necessary.
