Yet another mild day for the Tri-State; afternoon highs reached back into the mid to upper 80s throughout the Ohio Valley earlier on, but at least we're headed into a pleasant evening. After seeing the mercury dip toward 83° or 84° around dinnertime, we'll bounce back down to 75° or so around 10PM before bottoming out in the mid 60s area wide early Saturday morning - we'll fall to 65° in Evansville during the predawn hours Saturday. Even with a morning low 3° below the norm, temperatures tomorrow morning will be warm enough to give the mercury a bit of a running head start Saturday, especially with an ample supply of sunshine and southerly winds. The combination of the two will lead to our first 90° of the month and our hottest day in over a week.
Worse yet, that aforementioned southerly wind will pump not only more heat into the Ohio Valley, but also more of that gulf humidity. The added moisture will make tomorrow's high of 90° feel more like 92° at times Saturday afternoon. Sunday looks even more uncomfortable - We'll tip the scales that afternoon at 93° in the River City (our hottest day since June 28th) under partly cloudy skies, but due point values inching closer to 70° could make it feel more like 97° that day. It looks as though Mother Nature will double down on this trend next week; current model data indicates that afternoon highs between Monday and next Saturday will range between 93° and 97° each day. Heat indices for each one of those afternoons could easily peak near 105°.
