Southerly Winds, Heat & Humidity to Return

After a stretch of gorgeous weather throughout the Tri-State, the unbearable heat and humidity heads for the Ohio Valley.

Posted: Aug 4, 2021 5:44 PM

Temperatures across the Tri-State continued to trend higher this afternoon - peak temperatures topped out in the mid 80s for most of us as Evansville hit its highest temperature in a week; we recorded an afternoon high temperature of 85° in Evansville earlier today. Despite the added heat this afternoon, if you have plans out and about this evening, you're in the clear - it should be another absolutely gorgeous night up and down the Ohio Valley. After seeing the mercery dip to around 80° at dinnertime, we'll fall to 71° by 10PM before dwindling back down into the upper 50s and low 60s early Thursday morning.

The core of high pressure responsible for all of our gorgeous weather of late will continue to keep the skies clear both overnight tonight and for our Thursday ahead - unfortunately, that high will push to our east by tomorrow afternoon, allowing southerly winds to settle back in across the Tri-State. While we'll kick off our Thursday morning with a low temperature of 61° in Evansville, the presence of that weak southerly wind flow will allow us to match Wednesday's high temperature of 85° by our lunch hour. The mercury won't stop there however, we'll continue to see temperatures climb higher through the remainder of the afternoon - much of the region (Evansville included) will see peak temperatures near 87° on Thursday, but some of us south of the Ohio could record high temperatures in the low 90s!

The weekend ahead looks like a scorcher. Southerly winds will continue to pump more Gulf heat and humidity northward through the upcoming weekend; during that period temperatures will reach back into the mid to low 90s. Worse yet, the added humidity will make those temperatures feel a whole lot hotter - Friday's anticipated high of 89° will feel more like 91°. We'll hit an actual temperature of 91° in the River City come Saturday, but that could feel as hot as 94° and Sunday's high of 93° could have a "feels like" temperature near 100°. The latest model data continues to support the possibility of Monday being even more unbearable - current projections indicate that we could kick off the next work week with a temperature in the mid to upper 90s with heat indices between 100° and 105°!

The combination of sunshine and southerly winds will make for another abnormally mild day throughout the Ohio Valley - expect an afternoon high temperature near 69° this afternoon. Friday evening looks as though it will be just as pleasant; after seeing the upper 60s earlier in the day, we'll dip to 60° by 5 PM before falling towards 54° around 7 o’clock. We are however, watching a passing low pressure system and accompanying cold front that is expected to pass through the Tri-State late Friday evening and early Saturday morning.
