weatherwiz Posted November 17, 2013 Share Posted November 17, 2013 All the best ingredients are coming together over IL and then eventually into IN as well...the amount of instability present right now across IL is quite alarming given shear/helicity values in that area. 0-1km bulk shear values are exceeding 40-45 knots (That's completely insane) where you have SBcapes running >1000 J/KG, LI values as low as -4C to -5C, and 0-3km cape values exceeding 100-125 J/KG...plus this region is right on the nose of a 90kt MLJ streak. This is pretty to watch unfold. Link to comment Share on other sites More sharing options...
Geos Posted November 17, 2013 Share Posted November 17, 2013 If the NE IL storm heads the way it's supposed to it should enter WI southwest of Kenosha and towards the city or just north, which exactly where I need to go, but going to wait it out.

wisconsinwx Posted November 17, 2013 Share Posted November 17, 2013 Tornado warning extended east towards RAC/just north of ENW. Looking at the movement on radar, wouldn't be surprised if the cell makes a run at the Milwaukee Metro. Looks like it's moving just a tad N of due NE.

OUGrad05 Posted November 17, 2013 Share Posted November 17, 2013 These types of events are always scary for me. Many people especially in the upper midwest like this don't associate mid november with tornadic supercells. I hope people are paying attention, this setup is just potent as hell. I suspect we'll see these other areas get boxed up shortly. Link to comment Share on other sites More sharing options...
