Severe Weather Thursday
Things are shaping up for a severe weather outbreak over northern Illinois and southern Wisconsin on Thursday. The GFS model is showing a frontal system moving across the area, which combined with some good instability and an upper level jet should produce some widespread severe thunderstorms across the region.
The Storm Prediction Center has put a risk of severe weather across the region in their extended outlook:
… It appears that the severe threat will shift from the Plains on Day 4 (Wednesday, June 6th), into the mid-Mississippi Valley on Day 5 (Thursday, June 7th), as a fairly strong shortwave trough - accompanied by a belt of 60+ KT west-southwesterly mid-level flow - shifts northeastward across the Plains and into the upper Great Lakes region. Associated cold front will likely support vigorous storm development Day 4 over the Plains, then again Day 5 as the boundary becomes more northeast-southwest oriented over the Midwest. With a moist and unstable airmass forecast to be in place beneath a belt of strong west-southwesterlies aloft, numerous severe storms appear likely.
Stay tuned for more updates over the next day or two.
