Temperatures will drop into the 40s after sunset under a clear sky. Expect light winds overnight with patchy fog and a low around 38 degrees.
We are tracking a developing winter storm that is crossing the Rockies tonight. It will produce blizzard conditions over parts of NW Kansas and SW Nebraska on Wednesday. Heavy snow will track from Nebraska into Iowa Wednesday afternoon and evening.
We will be on the warm and wet side of this storm. Expect breezy south winds late Wednesday across the Tennessee Valley with no rain through Midnight Wednesday night. Afternoon highs will be in the middle to upper 60s.
Early Thursday morning a squall line of thunderstorms will be on the move. This line will track east and cross the Alabama / Mississippi state line between 6am and 8am and continue to track east for the rest of the morning and into the early afternoon hours. Within this line of storms there will be the potential for damaging straight line winds up to 60 mph and enough shear for a quick spin up small tornado. It is possible parts of North Alabama could be placed under a tornado watch due to the low level shear in the atmosphere. However, the primary threat will remain damaging wind gusts.
The rain will be gone by 3pm and temperatures will drop into the 40s by sunset on Thursday. They will fall below freezing by sunrise Friday. It will turn much colder into the weekend. Morning lows around 25 early Saturday with afternoon highs Friday and Saturday only in the 40s.
A look ahead to next week shows another storm system that will likely bring rain back into the Tennessee Valley for Christmas.
Have a great night.
