Monday Night Severe Weather Update.

Good evening and welcome in to IndyWx.com!

We continue to closely monitor radar and satellite trends tonight and keep a close eye on severe developments to our west.  As the video discusses, the clouds and rain from earlier today have helped in a big way from at least limiting what today “could have been” from a severe perspective.

That’s not saying we’re signaling the all-clear by any stretch of the imagination, it’s just saying that the clouds and rain from earlier have helped to keep us from really destabilizing the local atmosphere and the clearing we’re seeing now may be too little too late in regards to widespread severe weather here.

All of that said, keep a close eye on local radar tonight and remain weather aware.  The dynamics at play could result in a thunderstorm turning severe rather rapidly tonight and we’ll continue to closely monitor.

Strong to potentially severe thunderstorms will impact central Indiana during the overnight period:

Keeping A Close Eye On Severe Potential This Evening…

The region is still very much under the gun for potential severe weather this afternoon and tonight.  That said, the severe threat across central Indiana is highly dependable on just how easy we’re able to shake the clouds and rain this morning.  Sometimes modeling (even high resolution data) struggles with this.

The Storm Prediction Center (SPC) outlines the region for a Slight Risk of severe weather- again the primary threat time lies this afternoon into tonight.

Latest high resolution data suggests we’re able to clear things out this afternoon and introduce sunshine to help add heat and further destabilize our local atmosphere (not a good thing), which would help lead to rather robust thunderstorm development.

Note the simulated satellite data showing the dreaded clearing from now through the afternoon:

Latest high resolution data suggests potential super cell thunderstorms begin to fire to our west as early as 4-6pm.  We’ll keep a close eye on things.

Bottom line, a significant severe weather threat is present this evening into tonight.  We’ll hope the clouds and rain linger longer than modeling currently projects as this would greatly limit the potential heating and destabilization and subsequent severe risk.  That said, it’s important to note current data does suggest we break into afternoon sunshine.

Greatest severe risks here appear to be large hail, damaging straight line winds, and a possible tornado.  Be sure to have a way to get the latest weather information this afternoon and tonight.  Stay safe out there!
