TWO SHOTS OF RAIN SHOWERS
Friday: A few rain or snow showers, especially towards the higher terrain. Much colder and breezy. Highs 40-48. West wind 5-15 mph.
Friday Night: Scattered snow showers or flurries. Cold and breezy. Lows 21-27. Northwest wind 5-15 mph.

StormTrack 5 meteorologists are tracking a broad area of Arctic high pressure settling into the Great Lakes after a strong cold front. A strong cold front has moved through the region, producing showers and thunderstorms yesterday. In the wake of this front, we are left with cold and breezy conditions. I don’t expect many breaks in the clouds through the day, so temperatures will be in the mid to upper 40s…a near 30 degrees colder than yesterday!
Lingering moisture will combine with the falling temperatures to provide a chance of scattered rain or snow showers today and tonight. A light snowfall accumulation of around 1" or less is possible across the higher elevations. High temperatures today and tomorrow will be around 15° to 25° below average for late March!
A hard freeze is expected Saturday and Sunday mornings. That’s why a Freeze Watch is in effect for our lower elevations. Mountain counties in northeast Tennessee and southwest Virginia will fall below freezing, but are not included in the watch. That’s because not much vegetation is currently blooming in those areas. Remember to take plants, pets and valuables indoors during a hard freeze. This will be our first freeze in nearly three weeks!
Lows Sunday morning may drop into the upper 10s to lower 20s, thanks to clear skies and calm conditions. The record low Sunday morning is 19 set in 1966.
The second half of the weekend will remain fairly cool, but not as cold as Saturday! As high pressure builds south, warmer air will return to the region early next week. Expect winds to turn from the southwest on Sunday and supply us with a mild and sunny day to wrap up the weekend.
Clouds will be on the increase during the evening as a storm system to the north drags a cold front out way. A fast-moving front will bring a brief shot of showers again on Sunday night and Monday.
Tuesday and Wednesday will see high pressure moving warmer air into the region from the south. This will moderate temperatures, and send them into the 60s to near 70 degrees. As another storm system to the north comes into play, both forecast models are in disagreement. What this storm system means to us now is that there’s a chance at rain showers on Thursday with temperatures still near the average for this time of year.
Recap: Highs in the 40s to around 50 on Friday, and 30s to around 40 Saturday and 50s Sunday, and near 60 Monday. Mid 60s to near 70 at times Tuesday through Thursday. Lows 35-42 tonight, 20s Friday night and upper teens to low 20s Saturday night, and 30s Sunday and Monday nights…40s Tuesday and Wednesday nights.
Our average high is 62°, low 37°.
