Weather Summary:

We are tracking a strong cold front in the StormTrack 5 Weather Center. Ahead of this system, clouds are on the increase.  Be alert for area of dense fog this morning.


StormTrack 5 meteorologists are tracking a wintry setup in the tonight into parts of tomorrow. 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 this afternoon ahead of the front.

If you have any outdoor Halloween plans on today, the earlier the better. This evening and night may be a little wet for the trick or treating.  Make sure to bring the coats and umbrellas.

Cold air will pour into the region behind the cold front tonight changing the rain to snow (first in the mountains about 2500 feet by midnight and between midnight and 3 AM Saturday in the Tri-Cities). Temperatures will drop to near or below freezing tonight, 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 up to 3" are possible for the valleys (below 2000 feet). Any accumulations in the Tri-Cities will be mainly on the grass, cars, decks, and other elevated surfaces.

Snowfall for the middle elevations (2000 to 3000 feet) will likely be 2 to 5" 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 around 3000 to 4000 feet will likely be 3 to 7" with locally heavier amounts. More than 6 inches possible above 4000 feet with mountain tops above 5000 feet possibility getting more than a foot!

Roads across the higher terrain will become hazardous, so be on the alert for snow and ice covered roads in these areas tonight and tomorrow. *Snowfall totals will greatly depend on elevation.*

Tomorrow, 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, as low pressure continues to dive to the southeast.

Clearing skies Sunday. We will be chilly though as the low pressure area with our departing system joins forces with high pressure in the Great Lakes to bring in cold air from the north.  Overnight lows will likely be in the teens to mid 20s, depending on elevation.

We rebound quickly Monday and Tuesday, as temperatures warm up.  The Great Lakes high pressure system 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 today and lower 40s tomorrow, upper 40s Sunday and the 60s Monday through Wednesday. Lows will be in the low to mid 30s tonight and tonight 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°.
