Still chilly this week but temps slowly moderate. Precipitation chances too at times.

We expect another chilly night to start out December here in the Tennessee Valley. It definitely feels like the Christmas season! Clear skies and calming winds overnight will allow temperatures to drop below freezing right after sunset, and then we drop into the 20s overnight. Overnight lows will be in the lower to mid 20s, but I can't completely rule out an 18 or 19 degree reading in some of our naturally colder valleys and other rural areas.

Temperatures will moderate a fair amount as we head through the rest of the week and the weekend, but they will still be chilly. Afternoon highs will climb into the lower 50s on Wednesday and then hang out between the mid 40s and lower 50s for the rest of the week and weekend. Overnight lows will generally range from the low to mid 30s as we head forward.

Our next weather system approaches the area late Wednesday night and Thursday. Early Thursday morning, as precipitation first begins, I can't rule out a few sleet pellets or snowflakes briefly mixing in with the rain, but temperatures will be above freezing and warming going forward. That will ensure that everything will be rain as we head through the morning, with periods of showers lasting well into the evening and overnight Thursday night.

Models are conflicted, but there is enough credibility to leave a chance of showers in for Friday into Saturday as well as another disturbance moves through. We also can't rule out a light wintry mix overnight Friday night as temperatures drop into the 30s. At this time, we expect no accumulation or travel issues.
