Warm air dominates much of the eastern half of the USA as high pressure continues to hang across the region. That trend again continues through today and Wednesday with highs both days in the low to mid 80's. In fact, Chattanooga could see highs nearing the mid to upper 80's by tomorrow afternoon.
Looking below, high pressure will continue to shift east today allowing for southerly flow overnight tonight and into Wednesday. This will increase temperatures as well as dew points, setting up shop for rain tomorrow night and into Thursday. A chance for moderate to heavy storms (including lightning, gusty winds, and small hail) will be possible Thursday afternoon.
We aren't expecting any severe weather as the better parameters (though marginal) will hang west of East Tennessee. This should be a pretty quick moving system bringing a range of 0.5" and 1 inch Wednesday night through Thursday night. A few isolated to scattered showers hang around for Friday before better opportunities into Saturday.
The biggest news will be the heat today and tomorrow. Temperatures well above the average are in the forecast so be sure to practice heat safety. Even with temperatures in the 80's heat related illnesses can strike if you aren't careful.
