Risk Of Severe Storms Next 36 Hours

Scattered, strong storms are possible later tonight in western/northwestern Indiana…and the heavy rain from downstream leftovers may dampen the Thursday morning commute for some.

Based on latest computer model data, the Storm Prediction Center decided to upgrade western Indiana to a Moderate Risk of severe storms for Thursday.  This is an area where atmospherice wind shear/instability will be maximized…and offers the greatest threat to produce damaging wind/tornadoes.  However, all of Central Indiana is under a Slight Risk for severe storms late Thursday/predawn Friday.


All modes of severe weather are possible with an elevated risk of damaging wind, flooding rain and tornadoes along the leading edge of the squall line.


By Friday 7am rain amounts may approach/exceed 3″ in locations where storms “train” from southwest to northeast.  So river flooding and street flooding are likely.


It appears the main timing of severe storms for the WTHR viewing area will be between 6pm Thursday and 2am Friday.  Below is a series of hi-res FutureTrak 13 images…don’t focus on exact time of arrival yet (which is subject to change in any given area), but the idea is that this will be a late event for the squall-line.


By 7am Friday morning a cold front will push the severe threat, and warm air out of the state.   Thursday highs near 80° will be contrasted by temps tumbling into the 40s Friday afternoon!

The chilly air lingers into the first half of the weekend, with Saturday morning lows dipping into the 30s for the Race For Cure.  But the weekend will also be bright, as the cool air is dry.
