wisconsinwx Posted July 17, 2011 Share Posted July 17, 2011 Does that cluster just south of MSP have any chance of intensifying as it moves ESE? The current storm mode doesn't seem to be as linear as first thought; most of the storms are supercellular in nature. Link to comment Share on other sites More sharing options...

Thundersnow12 Posted July 18, 2011 Share Posted July 18, 2011 Looks like it could produce very soon. It most likely will not IMO. its updraft is sucking in cooler near sfc air parcels as its behind the boundary put out by the big supercell which just gusted out and weakened significantly.

Thundersnow12 Posted July 18, 2011 Share Posted July 18, 2011 Actually looking at things a bit now, if anything thats going on currently gets to us down here, it will be the storms/complex in northern WI that will continue southeastward until it hits the instability gradient and follow that southward into southern WI/northern IL. These things in situations like this sometimes travel to the right a bit of the mean wind as well. Link to comment Share on other sites More sharing options...
