Skies are beautiful and clear this afternoon, but looks are often deceiving this time of year. Temperatures even this mid-afternoon are still down around January standards, in the mid to upper 40s in southern Tennessee and in the lower 50s for northern Alabama. Winds are also brisk today, out of the north to northwest at 10 to 20 mph. This is making it feel like it's in the lower 40s.
Clear skies and a wind that will calm down after dark means that temperatures will drop quickly. We look to drop into the 30s not long after sunset, and then we're headed for the mid to upper 20s for most everyone by daybreak on Tuesday. However, some of our naturally colder valley and sheltered locations could easily drop to the lower 20s.
High pressure will be overhead for Tuesday, and that means that sunny skies will continue. However, temperatures will still be chilly, only reaching the upper 40s and lower 50s. That high pressure shifts east of the area on Wednesday. We get a southerly wind because of that, and under partly sunny skies, we look to climb into the 55 to 60 degree range by afternoon. Thanksgiving day on Thursday features a big cold front that brings rain to the area, especially from the late morning into the early evening. All that looks to be gone by Black Friday, with a return back to sunny skies and highs in the mid to upper 40s.
Thanksgiving travel weather looks a bit unsettled in spots, but not overly disruptive. Showers will be located on the cold front from the Ohio Valley into the Southeast, with maybe a few thunderstorms along it from Louisiana back into Texas. The Great Lakes may see a bit in the way of lake effect snow showers. The Pacific Northwest has a new frontal system that looks to bring in rain, with snow in the higher elevation areas. Otherwise, the rest of the nation looks relatively quiet.
