One More Very Hot Day, Strong Hump Day Storms
HEAT INDEX VALUES 105-110 TOMORROW; BACK TO NORMAL TEMPS END OF WEEK
After seeing highs in the upper 90s the past couple of days with heat index values in the 105-110 range across the area, we’ll see one more very hot day before we see some relief. A cold front currently over the Ohio and Tennessee river valleys will meander south, bringing an end to the stifling heat. Don’t get me wrong, it will still be warm towards the end of the week, but back to normal summertime levels with highs in the 90-94 range and lows 70-75 as opposed to the oppressive upper 70s we’ve seen the past few mornings.
The relief will come at a price tomorrow, as the entire viewing area has a marginal risk of severe weather. The main risk is damaging downburst winds from the incredible amount of heat energy and instability in the atmosphere; the hail risk is very small, and winds aloft are extremely unfavorable for any rotating storms, much less tornadoes.
After showers and storms are likely tomorrow, the chance for rainfall will decrease drastically for the end of the week as the cold front clears the area. It will get hung up somewhere near the Florida border, however, and with it still relatively close by, we can’t totally rule out a stray shower or thunderstorm on any given day through the weekend.
