Dangerous Heat Returns

Temperatures in the 90s and heat indices approaching 105° return to the Tri-State.

It's been a brutally hot start to our work week - the mercury jumped to its highest point in a week and a half earlier this afternoon. Worse yet, heat indices (those "feels like" temperatures we always talk about) reached above 100° at times earlier on. As a result, the National Weather Service expanded a Heat Advisory to include the majority of the Tri-State for not only the start of our week, but through Thursday at 7PM. It's expected that between now and then, conditions will become dangerously hot in spots with "feels like" temperatures pushing north of 105° at times. As for the remainder of this evening, conditions will remain clear, muggy and mild - temperatures will dip toward the upper 80s around dinnertime before only falling as low as 72° early Tuesday morning.

Tuesday looks as though it will be a degree or two hotter throughout the Ohio Valley; the latest model data suggests that Evansville will reach up toward 94° with a heat index of 102°. Scattered cloud cover will linger atop the Tri-State through our Tuesday and our midweek alike; one thing to note about our Wednesday ahead, temperatures will again be warmer. Current model data supports projected high temperatures come Wednesday topping 95° for the first time this year - as of right now, we're anticipating an afternoon high of 97° in Evansville with a heat index of 105° that day. If that forecast holds, not only will it be our hottest day of 2021, but our hottest day in the River City since July 22nd, 2017, when we hit 98°.

It was another chilly start across the Tri-State; while we only dipped as low as 43° in Evansville, many others across the Tri-State fell into the upper 30s earlier this morning. The cool air didn't linger long however, temperatures quickly reached back into the mid 70s across the region this afternoon - higher pressure camped out over the southeastern quarter of the country will continue to keep the skies above the Tri-State clear while gradually driving temperatures higher over the next few days. Despite our anticipated southerly winds this evening, you may still want to grab a jacket before your head out to dinner; after seeing a temperature near 64° around dinnertime, we'll fall off toward the mid to upper 50s by 10 o'clock. Overnight lows will again dwindle into the mid to low 40s for the majority of the Ohio Valley early Tuesday morning.
