Another Round Of Northwest Flow Snow For WNC
Yes, another round of Northwest flow is on the way, and some high elevations locations are going to get hammered with 6”-12”+ inches of snowfall Sunday and into Monday. This will replenish the snow that has melted over the past few days with the temperature increase/rain. This flow looks to be very stout, similar to the one we saw last week, but it seems to be a bit more intense. The timing is also a bit more conducive for accumulation to occur as the main moisture will move in at sunset instead of sunrise. I suspect that locations around Asheville and just north could rake in another 1-3”, similar to the last event. Rates will not be as strong though as temps will remain in the low 30’s as snow falls. Therefore I can see this being a wet snow that sticks to everything. Below is my projected accumulation map for this event as well as a projected radar from the 12z NAM 3km.
Heavy Rain/A Few Rumbles of Thunder Today For WNC
Areas South of Asheville will see consistent rainfall throughout most of the day today as the front moves through. Most models show around an inch of rainfall possible for Hendersonville and as you get closer to Asheville those totals diminish to .6”-.7” of precip. Below you can see the most recent Nam 3km precipitation totals through this evening. The ground is already very wet so some flash flooding could occur.

Snowfall Timing
When will snow begin around WNC? Most models suggest that snow will begin in the high elevations above 3500’ around 8-10am, and then by 1-2pm snow showers will begin to drift into valley locations like Asheville and Waynesville. I expect this snow to pick up in the valley floor areas as the sun sets, so it would be wise to be where you need to be on Sunday evening by 4-5pm. Snow will really become heavy for most locations north of I-40 as the sun sets around 6pm. Check out the most recent NAM3km simulated radar and snowfall projection.
