We have some good news for your Thursday! In addition, to the gradually warming temperatures, the drought monitor shows back to normal conditions for nearly the entire state. We are still sitting abnormally dry around Chattanooga, but overall the last bit of rain and snowfall has brought the state back to normal.
As we work into the afternoon, highs will top out in the mid 40's with clouds building. A system will continue to develop bringing rainfall to our friends in the east (Carolinas and up the coast) but we will stay dry here in the valley. Working into tonight, the Smokies could see a shower or two, otherwise we will clear out by Friday afternoon. Looking at model guidance cloud cover below, lighter shades indicate increased cloud cover overnight. By tomorrow afternoon, darker shades return, suggesting sunny skies. High's to end the work week will be in the low to mid 50's.
The surface map shows the development of the system to our south. Moisture will soon be advected into the Carolinas through the day bringing rainfall in overnight. As for east TN we will see clouds through the night (locking in some warmer low's) before clearing out by Friday afternoon and into the weekend. A high pressure system to the west will bring in sunny and dry conditions for the weekend, where we will see high's near 60 on Sunday.
That will do it for today, so have a good one!
