Expecting a real ass kicker storm in Wisconsin Wednesday night & overnight into Thursday. The SPC has placed an ENHANCED RISK for portions of Wisconsin.

The combination of a large instability pool, strong wind shear, and somewhat organized low pressure system could lead to severe weather, potentially some pockets of widespread wind damage. Hail and tornadoes possible too. Parameters will be as strong as they get for Wisconsin.

I am concerned about this system and will be watching closely.

How are the parameters shaping up? I see the SPC has upgraded us to "MDT" Yikes, quite rare for our area!
