Strong Storms Possible Ahead Of Cold Front Today

A cold front is expected to push eastward across Wisconsin today, exiting far eastern Wisconsin by sunset. The best chances for storms will be across southeast Wisconsin this afternoon. There is some uncertainty over how widespread the storms may be as much will depend on how much clearing we get today.
Very unstable conditions ahead of the front, combined with weak to modest wind shear aloft, may allow for some strong storms to develop.
The Storm Prediction Center has a Marginal Risk of severe storms forecast for parts of southern Wisconsin. This means that an isolated severe storm is possible. See the map below.
Damaging winds and large hail would be the main hazards, if any of the storms become strong.
