We are tracking a strong cold front in the StormTrack 5 Weather Center. This front and its associated low pressure system have since passed through the region, aiding us with cooler air and snowfall through the mid-day hours.
StormTrack 5 meteorologists continue tracking this wintry setup into parts of the afternoon with the higher elevations favored for heavier snowfall and higher accumulations, though the numbers have come down given the recent trends in observations.
Cold air pouring in behind the front has allowed for a transition from rain to snow for almost the entire area. Winds coming from the northwest are pushing the cold air up the mountains, which is part of why these locations will see higher accumulations into the middle of the day today. Some left over snow flurries and showers are possible, but don't seem to pose too much of an additional accumulation threat.
Snowfall totals of a dusting to around 2" 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 1" to 4" 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, Sam's Gap, 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 getting a foot or more!
Roads across the higher terrain will likely become hazardous, so be on the alert for snow and ice covered roads in these areas through parts of the day. *Snowfall totals will greatly depend on elevation.* Something else worth noting is that power outages and downed trees are possible across the higher terrain. Due to the wet snow falling on trees still covered by foliage, this could become a potential hazard...especially in higher elevations.
Skies will remain partly to mostly cloudy overnight while temperatures plummet back down in to the mid to upper 20s. Breezy conditions will stick around, meaning wind chill values in the upper teens to low 20s are possible. Make sure that you keep the extra layers handy throughout the weekend.
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. Lows Sunday night will likely be in the mid teens to mid 20s, depending on elevation. Wind chills will be a factor through Saturday with wind chills in the 20s for the Tri-Cities and 10s in the mountains at times.
We rebound quickly Monday and Tuesday, as temperatures warm up. The Great Lakes high pressure system slides east and we pick up on warmer air arriving from the south. Highs will be near normal in the afternoons. A new system will increase our chances of rain on Wednesday into Thursday with partly to mostly cloudy skies.
After this system passes through, we are left with a pleasant end to the week. Partly cloudy skies and high temperatures feeling pretty mild: mid to upper 50s.
Don't forget to set your clocks back an hour before you go to bed tonight. 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 near 40 today, mid 40s Sunday, and in the 60s Monday through Thursday. Lows will be in the low to mid 30s tonight and 20s Saturday night and Sunday night before warming back into the 30s and low 40s Monday night through Wednesday night.
