wisconsinwx Posted April 17, 2013 Share Posted April 17, 2013 With the 12z GFS indicating the secondary low moving through SC Wisconsin tomorrow afternoon, I would think the risk of severe weather is there as far north as Milwaukee. Link to comment Share on other sites More sharing options...

SchaumburgStormer Posted April 17, 2013 Share Posted April 17, 2013 Starting to hear thunder here. Getting quite dark to the southwest. Looks like the warning near DKB was dropped. Still looks like a solid boomer rolling through DKB.

frostfern Posted April 17, 2013 Share Posted April 17, 2013 I think the complex over Eastern Iowa is going to morph into an elevated MCV. There is nice backing wind at 850 ahead of it.

Hoosier Posted April 17, 2013 Share Posted April 17, 2013 0-1 km shear looks very impressive tomorrow...hodos do tend to flatten out above that but any QLCS could certainly have considerable damaging wind potential at the very least.

BOWING SEGMENTS AND EMBEDDED SUPERCELLS WILL BE FAVORED...ESPECIALLY WITH NRN EXTENT GIVEN THE DEGREE OF SHEAR. POTENTIAL WILL ALSO EXIST FOR DISCRETE SUPERCELLS DEVELOPING AHEAD OF THE QLCS AS MLCIN BECOMES MINIMAL. THIS WOULD SEEM TO BE MORE PREVALENT WITH SRN EXTENT WHERE LARGE-SCALE ASCENT WILL BE PROGRESSIVELY WEAKER. SWATHS OF WIDESPREAD DAMAGING WINDS APPEAR PROBABLE ALONG WITH A ROBUST TORNADO RISK /SOME OF WHICH COULD BE SIGNIFICANT/.
