The Weather Authority is closely monitoring a cold front that will bring the return of rain and storms to the Tennessee Valley. A cold front is forecast to track into northwest portions of Alabama early Thursday morning. This line will then move eastward through the late morning and early afternoon. Heavy rain and strong storms will be possible, especially along and east of I-65. The Tennessee Valley will have the threat of storms between 7 a.m. and 1 p.m.
The Storm Prediction Center has highlighted parts of Alabama and Georgia for the risk of severe storms associated with this system. The majority of the Tennessee Valley has been included in a Slight Risk (level 2 out of 5) for the development of strong to severe storms.
The main severe threat will be damaging winds. Rainfall amounts of 0.25 to one inch will be possible across our area. This could lead to power outages and trees down. While the tornado threat is low, it’s not zero, so stay weather aware. We’ll watch for any embedded circulations in the line.
Gusty Winds Outside Of Storms
With a strong low-level jet and a tight pressure gradient associated with this cold front, winds will be strong outside of any storms. Sustained winds Wednesday night through Friday will be between 10 to 20 mph. Wind gusts will be between 35 and 40 mph.
On the back side of this system, there’s a chance of a rain/snow mix Thursday night and light snow on Friday. Temperatures by Friday afternoon will only be near 40 degrees. Watch bridges and overpasses if you have to head out because they cool quicker. Snow amounts could range from nothing to 0.50 inches in the higher terrain.
