We are tracking a strong cold front in the StormTrack 5 Weather Center. Ahead of this system will we see partly cloudy skies overnight with lows in the mid 30s. Be alert for area of dense fog overnight into Friday morning.
StormTrack 5 meteorologists are tracking a wintry setup in the Tri-Cities Friday night into Saturday. A storm system will move through the Great Lakes in conjunction with a cold front that will head our way. Scattered rain showers will develop Friday afternoon ahead of the front.
If you have any outdoor Halloween plans on Friday, the earlier the better. Friday evening and night may be a little wet for the trick or treating.
Cold air will pour into the region Friday night changing to rain to snow (first in the mountains about 2500 feet by midnight and later in the Tri-Cities). Later on in the evening to overnight, temperatures will drop near or below freezing for most, with higher elevations achieving this quicker than the valleys. The wind direction from northwest will help produce lift especially across the higher elevations.
Snowfall totals look light for the valleys (below 2000 feet). Any accumulations in the Tri-Cities will be around 1 inch or less and mainly on the grass, cars, decks, and other elevated surfaces.
Snowfall for the middle elevations (2000 to 3000 feet) will likely be 1 to 3" with locally heavier amounts. Our forecast data is indicating quite a bit of snow accumulation is possible above 3000 feet. This would include places like High Knob, Whitetop, and Roan Mountain. Snowfall totals above 3000 feet will likely be 3 to 6" with more than 6 inches possible above 4000 feet. Roads across the higher terrain could become hazardous so be on the alert for snow and ice covered roads in these areas Friday night and Saturday. Snowfall totals will greatly depend on elevation.
On Saturday we expect flurries or snow showers in the area. In the valleys, the snow will mix with or change to rain showers during the day while snow showers will continue in the mountains, especially for the snow-prone northwest facing slopes. Gusty winds and cold temperatures will make it feel like winter Saturday! Flurries should taper off Saturday evening.
Clearing skies Sunday. We will be chilly though as the low pressure area with our departing system joins forces with a high in the Great Lakes to bring a cold northerly flow. The departing low will likely become a Nor'easter for the New England states as it strengthens and moves off the coast.
Monday and Tuesday, temperatures warm up as the Great Lakes high slides east and we pick up that warming south to southeasterly flow again. Highs will be near normal in the afternoons.
A new system will increase our chances of rain on Wednesday with mostly cloudy skies.
Don't forget to set your clocks back an hour before you go to bed Saturday night. Daylight saving time ends Sunday morning at 2:00 am. Finally a chance to get back the hour of sleep we lost in back in March!
Highs will be in the lower 50s Friday with lower 40s Saturday, upper 40s Sunday and the 60s Monday through Wednesday. Lows will be in the low to mid 30s tonight and Friday night with 20s Saturday night and Sunday night before warming back into the 30s and low 40s Monday night through Wednesday night.

Our normal high is 65°, low 39°.
