Another frontal passage will occur during the afternoon on Sunday, and with it could be a strong line of storms. Below you can see the most recent NAM 3km depiction of the system as it pushes through later in the afternoon on Sunday. High winds, lightning, and even isolated hail are possible with this system as well as flash flooding across the area. Watch below at the end of the run and you can see the line of storms enter WNC.
High Winds Likely Sunday
Winds will blow out of the South on Sunday before the frontal passage, and gusts will reach over 40 mph in some locations. Below you can see the NAM 3km in the early afternoon. Notice how most stations in WNC are showing +40mph peak gusts during those times. Also notice how the wind barbs are positioned out of the South.
Another Freeze Likely To End Next Week
Do not plant your tender veggies just yet in WNC, another frost is likely on the way to end the week next week. Models indicate that temperatures in the upper 20’s will be possible both Thursday and Friday of next week. Prepare to bring in or cover sensitive vegetation that you have planted ahead of this frost to protect your plant investment. Below you can see the GFS projected temperatures for early Friday morning in WNC. BRRRRR… hopefully this will be our last frost but they are possible through early to mid May.
Chance For Snow Showers Around WNC Late Next Week
Models are indicating that there is a chance for some snow showers late next week around WNC as a cold front moves through. There is still great uncertainty, but it does appear as though at least for the higher elevations that wintry weather is not done for the season. Heavy snow will be possible above 3500’ with this system and even several inches of snow could accumulate in isolated areas. I’ll have more info on this later next week, but here is what the GFS shows for Thursday morning of next week.
