Good Wednesday. Look for another warm and humid day with a high of 92 and a few spotty showers here and there. The rain chance today is 30%. East of Chattanooga, in the Blue Ridge, the rain chances are a bit higher at 60%.
I think we may get some more widespread rain Thursday afternoon as a front passes through. Thursday's high will reach 90 and the rain chance will be 60%.
Friday the front will be to our east so our rain chances will be a bit lower. I would still expect one or two showers, though.
The weekend will bring in another front that will stir things up a bit. Through the day Saturday and Sunday we will have periods of rain on and off that could bring us 1" to 2" of rain by the end of the weekend.
Next week looks pretty amazing. Monday through Wednesday we will have mostly sunny skies with lower humidity and highs in the upper 80s.
