Another scorcher today, and sunshine dominates the weekend forecast

It's going to be another hot one, folks. A heat advisory is in effect this afternoon for Giles,

Lawrence, Wayne and Hardin counties in Tennessee. Heat indices could reach 107°. An excessive heat warning is in effect for Tishomingo County, Mississippi as well as Lauderdale, Colbert, Franklin and Lawrence counties in Alabama through this evening. Heat indices could reach 114° in these counties.

Here's a look at future heat index values, valid at 3:00 p.m. Thursday. Stay indoors if you can.

Will storm chances bring any relief to the heat? Probably not. Rain chances this afternoon are spotty at best for North Alabama, and I don't think Southern Tennessee will see a drop in the rain bucket this afternoon. Most of us will stay dry under a partly cloudy to mostly cloudy sky.

After today, the Tennessee Valley will see nothing but sunshine through the weekend. Rain chances are minimal to non-existent. Without a chance of rain and a lack of clouds, this weekend will be hot. Air temperatures could hit the triple digits Sunday and Monday. Heat index values will be warmer than 100° for the next several days.

The next decent rain chance for the Tennessee Valley is Tuesday and Wednesday. I threw in a 20% chance for afternoon storms Monday, in typical summertime fashion. But by mid-week, we will see another front move through, providing us with slightly higher rain chances.
