Wednesday will be a close repeat of today, with (potentially dense) fog early. The main difference? Temperatures reaching the lower 60s during the afternoon…a great treat!

Latest HRRR Model Loop
Wet weather will come to an end later this afternoon, just in time for the evening rush hour. Temperatures will be unseasonably cool in the 40s, dropping into the upper 30s overnight.
Cloud cover will be intermittent today, with cold temperatures being the main story. Most places around Davidson/Williamson Counties will struggle to reach the upper 20s!
One last, brisk night is in store with forecasted lows in the teens, followed by a “warm up” Sunday and beyond. There’s just one speed bump in the way…
GOES 16 Loop from this morning
If you were out the door early, WOW was it cold. Some Middle Tennessee locations set local low temperature records, like Crossville at 1ºF. Sunshine should help our area rebound into the middle 20s today, and winds will be dying down. Thus, the Wind Chill Advisory ends at noon.
As it turns out, we can go pretty low. Believe it or not, today’s official forecast high of 36ºF will be the highest temperature of the entire forecast period. Yikes!
European Model – 850mb Temperature Pattern Through Next Sunday
Most thermometers were reading in the teens this morning, but thanks to dry air, we will warm up into the middle 30s this afternoon. A few passing clouds are expected throughout the day, with a steady increase in cloud cover by Friday afternoon and evening. Saturday, temps will begin their nose dive in the mid-30°s, too cold for paintball or any other reasonable outdoor activity, then Saturday night we’ll plunge below freezing and stay there for the next four days.

Temperatures will fall tonight as more dry, cold air digs into Middle Tennessee. Highs on Wednesday will struggle to reach the freezing mark, so make sure to bundle up!
Since writing the blog this morning, NWS Nashville has since gone ahead and issued a Flash Flood Watch for Friday and Saturday:

The latest hydrologic outlook from NWS Nashville says it all:
Rain will likely start after sunset tonight and continue through the day on Wednesday. Rain will finally come to an end, but only briefly, early Thursday morning.
Side note: GOES 16 is back as GOES EAST!
Preliminary satellite this morning shows a few passing clouds over Tennessee, but nothing to keep the sun from shining. Temperatures this afternoon will soar into the 50s, a nice warmup for mid December.
