Storms Possible....

Well starting off mild with temperatures across the area in the upper 70s to lower 80s. The quasi-stationary frontal boundary that aided in the development of storms that caused all the wind damage from Connecticut down to Texas is still west of the Tennessee this morning.

SimuAWIPS Frontal Analysis 6:30 AM/Radar at 8:55 AM
I do expect as frontal boundary continues to approach the region some showers and thunderstorms will form out ahead of the main boundary. The question this morning is how much will the atmosphere be able to recover in order to get development across East Tennessee. Right now NAM, RAP, and WRF models are indicating storms moving into the Valley around 2 PM and the HRRR shows some activity at 2 PM with more through 5 PM.  Expecting marginal instability but weaker upper level support, so little in the way of severe weather today. Main threat with these storms will continue to be damaging winds with stronger storms. I will continue to monitor throughout the day for development. Tomorrow will be drier as weak boundary moves through the area with highs in the lower 90s. The biggest affect from the frontal boundary will be the drier nights with lows getting back into the upper 60s. Sunday another drier day with highs in the lower 90s. Chances of storms increase Monday through Wednesday with best chance right now Wednesday.
