Batten down the hatches tonight southern Wisconsin.

According to the National Weather Service:

An isolated threat for strong to severe storms with damaging winds and perhaps a brief tornado exists for southern Wisconsin and northern Illinois this evening.  The primary threat is for damaging straight-line winds, but a brief tornado can't be ruled out according the The Storm Predication Center in Norman, OK.

Unseasonably warm and humid air pushed north into southern Wisconsin in the early afternoon hours of December 3, 2012, which set the stage for thunderstorms.

Here is the story: The Storm Prediction Center.

Severe weather spotters should send severe weather reports via E-spotter, telephone, or Twitter.  However, we may miss a report via Twitter, so use E-spotter or the telephone.
