Low to medium chance of a rain/snow mix late this afternoon into the evening hours on the Cumberland Plateau. No accumulation expected.
Very chilly air will continue to build in with a widespread hard freeze this weekend.
Dry with a gradual warming trend next week.
I made a couple of changes to the short term forecast based on the persistent depiction of a light rain/snow mix on the Cumberland Plateau later today. As another bout of energy swings around the base of the upper trough to our north, it looks more than likely that our eastern counties will get clipped. Temperatures should be such that the falling precipitation starts as light rain, but as temperatures fall, I can see flurries start to mix in late this afternoon. While accumulations on the ground are not expected, I would not be surprised to see pictures and get reports of some collecting on cars and elevated surfaces this evening. The energy and moisture necessary for this to occur should exit the area by midnight. Look for chilly temperatures to settle in tonight, but with the cloud cover, our coldest morning lows will likely come Sunday morning.

Light showers are continuing to stream in from the north currently. We could continue to see isolated showers in areas east of I-65 overnight, but chances are decreasing as the night wanes on. Low temperatures tonight will bottom out in the low 30s to upper 20s, with clearer skies west of I-65, and more clouds in the east.
Friday won't be much warmer, as this air mass sets up over Tennessee for the weekend. 850mb temperatures are below zero, indicating a frigid temperature trend in our future. Highs for Friday will warm into the 40s and low 50s. Something that has to be mentioned is the chance for flurries on the Cumberland Plateau as a longwave trough continues to slowly push east Friday afternoon and evening. No meaningful accumulation or impacts are expected from these snow showers, as temperatures will be above freezing while it is precipitating. That being said, worst case scenario would be some light accumulations on colder surfaces.

A bigger story for us is the anticipated hard freeze this weekend. This will be our first widespread hard freeze, so make sure you are taking care of pets, outdoor or exposed pipes, sensitive plants, and checking on people around you who may be sensitive to the cold. Lows this weekend will be in the mid 20s areawide, with highs in the 50s continuing into the start of the work week.
After our exciting flurries in the east, a surface ridge will build in over Middle Tennessee for the work week. Highs will warm into the 60s by mid-week, with lows staying chilly in the 30s and 40s. This surface high will also help keep us precipitation free, which is not anticipated to help the ongoing drought.
