Friday Forecast...........Chances for Severe Weather

A thunderstorm watch has been issued for South-western Indiana and Southern Illinois. I expect a thunderstorm watch to be issued for our area later today. The main threats will be large hail, wind gusts up to 60mph, and an isolated weak tornado.

The chances for severe weather are thanks to an incoming cold front associated with a strong low pressure system. Also, temp in the mid 70s and dew points in the 60s will allow for an unstable air mass. Also, the upper low has a cold pocket which will allow for towering cumulus clouds to develop. Wind shear is also more than sufficient to allow for super cells to form.

Currently: We are in between 2 waves of rain. This will allow for some sun to show for the next few hours. This will warm our temps into the mid 70s. Rain/thunderstorms will start up again after 4.
