Severe Storms To Impact The Ohio Valley And Midwest

StormTrackerWx.com is tracking more severe weather across the Ohio Valley and Midwest this afternoon and evening.

The shortwave that aided in yesterday's convection over the high Plains will shift east into Iowa today.  This feature will serve as focus for severe development across Central Iowa, Missouri, and Illinois, where substantial deep layer shear will be more than sufficient for supercells capable of producing large hail.  Given the amount of low and deep layer vertical shear present, a few tornadoes will also be possible.

Rapid development and intensification is forecast further downstream of the trough axis across the Ohio Valley.  Sufficient daytime heating will promote steepening mid level lapse rates, with the potential for a very unstable air mass to develop across the region this afternoon.  As the shortwave propagates eastward, discrete cells over Illinois will likely evolve into a bowing MCS (Mesoscale Convective Complex), with damaging straightline winds and torrential downpours possible.

Additional severe weather is forecast across this region tomorrow, with cooler temperatures expected by the weekend.
