Tracking Active (Potentially Severe) Weekend Weather

We're in for a bumpy ride this weekend.

Good Evening,

I’m tracking two organized and potentially Severe clusters of thunderstorm activity that are expected to affect Greater Lafayette over the next 36 hours. A well-defined line of storms that has already triggered numerous Severe Thunderstorm and Tornado Warnings across parts of Oklahoma, Texas, Louisiana, Arkansas and Missouri will gradually make its way towards the Wabash Valley overnight.

Current model data suggests that the remnants of this potent line of storms will reach our southwestern counties by 2:00 A.M. ET Saturday. The organized, but unlikely Severe storms will continue on through the morning before exiting our easternmost counties between 8:00 A.M. ET and 9:00 A.M. ET tomorrow morning.

Plans on attending with the Purdue Challenge 5K or Spring Fest on Purdue’s campus tomorrow? Don’t fret; while there’s expected to be a few scattered showers throughout the morning and afternoon, I’m not anticipating anything more than some intermittent rain for Tippecanoe County through the late afternoon. It appears as though the heaviest rainfall tomorrow afternoon will affect the areas north of Lafayette.

That being said – Another, more potent system of thunderstorms is expected to form across potions of Central Illinois tomorrow evening before reaching Greater Lafayette before midnight. Strong convective energy directly ahead of the advancing low will further intensify the cluster of storms during the predawn hours Sunday. Some of the cells embedded within this complex of storms may generate hail larger than an inch in diameter along with damaging wind gusts of 60 mph and possibly isolated tornadic rotation.

In anticipation of Saturday night’s storms, the Strom Prediction Center of America has placed a good portion of the viewing area under a Marginal (1) to Slight (2) Risk for Severe Weather. While all of us may see large hail and strong winds, the areas highlighted in yellow (the Slight Risk) will see the greatest chance for isolated tornadic development. Remain weather aware over the next two nights.

The last of the organized storms, along with the associated low, will likely push east of the viewing area by 9:00 A.M. ET or so Sunday morning. As a result, temperatures at the surface will begin to fall. In fact, any lingering rainfall that afternoon and evening will gradually transition into a wintry mixture and even light snowfall by Monday morning! Let the spring weather roller coaster continue!
