High Heat Fuels a Severe Weather Threat

The threat of Severe Weather returns to the Tri-State.

Temperatures once again surged into the upper 80s and low 90s across the Tri-State earlier today. While temperatures haven't exactly been record-breaking, they've routinely topped out between 8° and 10° above the norm for this time of the year in recent days. Our abnormally warm weather however, may be on its way out of the Ohio Valley. A cold front approaching the Midwest overnight will allow cloud cover and rain chances to settle back in over the region early Wednesday morning - the added cloud cover and moisture will only allow temperatures to reach the mid to low 80s tomorrow (we'll reach 83° in Evansville). While we may see a few showers and storms Wednesday afternoon, the returning warmth Thursday will drive temperatures back into the mid to upper 80s. Expect the resurgence of heat to fuel additional thunderstorm activity late Thursday into early Friday.

In fact, the Storm Prediction Center has placed the entire region under a threat for Severe Weather during the predawn hours Friday. A passing core of low pressure will drag a cold front across the Mississippi Valley beginning late Thursday night; that cold front will interact with the ample amount of heat and humidity at the surface and produce a well-developed line of thunderstorms that is currently expected to reach the Tri-State around midnight early Friday morning. That line of storms may be organized enough to generate damaging straight-line winds, large hail and even tornadic rotation. The latest model data suggests that the threat of Severe Weather may linger for portions of the Tri-State through 6AM Friday.

Periods of scattered rainfall may continue to affect the Ohio Valley into Friday afternoon, but with the aforementioned low exiting the region it's unlikely those rain chances will last much longer than that. With the last of the rainfall on its way out, drier and cooler weather will return to the Tri-State; Friday's anticipated high of 79° will mark our coolest afternoon in over a week. Believe it or not, temperatures will fall even lower for your Saturday - not only will Saturday's high of 70° be about 11° below average for that date, but it will mark our coolest day since May 13th! As for the remainder of our Holiday weekend, both Sunday and Memorial Day look more mild; expect highs closer to the upper 70s and low 80s and plenty of sun those two days.

We woke up to dry and cold conditions this Tuesday morning. Unfortunately, there won’t be any drastic changes this afternoon. Increasing cloud cover will be likely as a cold northerly flow continues ushering in chilly air. Highs won’t be going very far, we’ll likely only reach the mid to upper 30s Tri-State wide. We’re tracking a little bit of winter weather out to our north and west. Skies will be mostly cloudy tonight with a chance of flurries/light rain. It won't be a big snow by any stretch, but you could see some flurries flying Tuesday night into Wednesday morning around the Tri-State. Don't expect more than a dusting, with greater chances falling north of I-64.
