Northwest Flow To Bring First Snowflakes Of Season To High Elevations In WNC Sunday Night
Itβs that time of the year again, where cold fronts begin to move in from the northwest and excess moisture gets strained out along the Appalachian mountains on the backside. Northwest flow. These events are where higher elevation locations receive snowfall, but as downsloping occurs into the valley these flakes are limited. A strong front will push through WNC late Sunday night, bringing the chance for the first accumulating snowfall of the season above 4500β. Only a dusting to 2β will be possible for the highest of elevations, but nonetheless, flakes will be flying in the High Country. Check out the most recent NAM 3km Snowfall Map for Sunday night & Into Monday.
High Winds Likely
Winds will pick up as the frontal passage occurs tomorrow evening, and will gust to 45mph around the Asheville area, and in locations above 3500β winds could gust over 60mph. Below you can see the most recent NAM 3km peak wind gusts for Monday Morning. Talk about a rough morning, Monday will be bitter cold around WNC! Bundle up if you have something outside planned.
The GFS model depicts the front moving through very nicely. Below you can see how the air moves in from the Northwest, just after a slight bit of precipitation over WNC moves out. I am expecting scattered showers tomorrow during the day before the frontal passage, then winds will switch and come out of the NW with authority. Several WNC Webcams should be showing snowfall late tomorrow, and a dusting will be possible on the Banner Elk, NC Camera!
Total Precipitation Expected Tomorrow
As this moisture starved front moves through, some southerly flow will bring in a few scattered showers as Sunday progresses. These showers will be light, but if outdoor activities are planned they could be hindered. Below you can see the total precipitation depiction for WNC. Locations along the Blue Ridge Escarpment will see higher totals with this southerly flow, but most all locations will see less than a half inch of precipitation.
Winds Will Pick Up Around Noon Tomorrow
The map below shows you the progression of the winds over the next 60 hours. Today (Saturday), will be a very nice day around WNC, but around noon tomorrow we will begin to see higher gusts of wind invade the mountains of WNC. It would be wise this afternoon to secure any outdoor accessories that could blow away.
