Behind a cold front, temperatures will plummet across the Tennessee Valley. High temperatures on Tuesday will struggle to get much higher than the lower 30s.
With the falling temperatures, some of the rain will likely change over to a brief period of sleet or snow tonight and early Tuesday morning. This will likely occur after midnight and come to an end before the morning commute.
I don’t expect any accumulation on the roads because the pavement will simply be to warm. Road temperatures are not expected to drop below freezing until after the vast majority of the precipitation has come to an end. Through much of the overnight, pavement temps will be in the 30s and 40s. The only accumulation I expect would be very light on the grass and other elevated surfaces.
The Big Issue
The big issue tomorrow will be the wind. Sustained winds will be 15 – 25 mph. This will create a big wind chill.
Waking up Tuesday morning with a sustained wind of 15 – 25 mph means a wind chill well into the single digits.
Through the rest of the afternoon, we hold onto that wind keeping wind chills in the teens and 20s.
While temperatures will dip down into the 20s tonight, and only rebound into the 30s tomorrow afternoon the worst cold will come Wednesday morning.
Many will start the day in the teens and lower 20s. From there we rebound into the mid-40s Wednesday afternoon.
