Does someone have the technology to take a look at the cell just southeast of Madison? It has an odd shape, but I doubt it's a tornado. I'm just curious if it's indicative of anything.

Do you mean the cell southEAST of Madison?? It has the look of a mini supercell but doesn't have any apparent significant rotation as per KMKX radar on the GRanalyst

Yeah, that's what I meant as I corrected it. The right side looked a tad suspicious as a triangular piece was cut out. I don't know how to determine rotation on radar very well, so if I see a little hook of any sort, I would question its significance.

Well it is in very tight to the radar so unless it is more evident it can difficult to discern what is going on. When in a PDS watch area and conditions are ripe like tonight, you would be plenty justified to watch any hook or notch.

The storm that passed over Manitowoc WI that is crossing Lake Michigan heading in the general direction of Manistee Michigan looks better now than while over land, I wouldn't write off these storms crossing the lake yet.

its not that i'm writing off the chance of svr, wouldn't surprise me at all to see some wind damage across western mi with temps still in the 70s keeping some instablity around, its just what could have been if the storms were a few hours quicker, if something could have went up ahead of the cold front, etc. When you see numbers like ehi of 8, supercell comp. of 28, and sig. tornado number of 6-8 you just kinda hang your head and think if only.......

edit: to clear things up a little, yes with those numbers things could go boom in a big way once the storms reach land, but to me nighttime tornadoes are useless because A: they don't provide the photographic element that i want on a storm/tornado and B: they are 10x more dangerous to chasers/spotter/general population.

The 700 mb temps in the warm sector were almost summer like.
