Happy hump day! Showers have stayed at bay so far today but a few scattered showers are possible this afternoon. Looking at the surface map below, the main system is just to our west. We'll see heavy showers and storms overnight before MUCH needed drier air works in Friday and the weekend.
It is important to note the SPC has a slight risk of severe weather tonight across middle TN, Chattanooga, and parts of the central valley. The main threat with these storms will be damaging winds but isolated spin up is possible as well. Be weather aware tonight as heavy rains can create flashing flooding and heavy winds can easy topple over trees. In addition to the severe potential, we are under a flash flood watch until 7am tomorrow.
As you can see, model guidance suggests some scattered showers this afternoon otherwise we'll stay mostly cloudy. Working overnight tonight and early into Thursday, a strong line of showers and storms will work through bringing heavy downpours and gusty winds. Expect showers to end entirely by the mid-morning hours tomorrow with cooler air to follow. A cold front will decrease temperatures throughout the day, so bundle up! In addition to the cold front, expect breezy conditions as well with gusts up to 20 mph.
Rain totals with this next system are around the one inch mark for east TN with locally higher amounts possible in heavier cells. With an already saturated ground and the chance for heavy rain, flash flooding can be a concern overnight.
I know more rain isn't something we want to hear but much better weather follows Friday and the weekend. Stay weather aware and safe tonight and check back in for updates!
