Long Range Models Show Pattern Change, Arctic Air For Southeast Late Next Weekend

Some rain/snow showers are possible around WNC this evening and into tomorrow, with higher elevation locations(above 3500’) seeing some form of accumulation. I don’t expect to see totals much over 3” though even in the highest elevations. I have moved my focus towards the pattern change that will occur late next weekend. Long range models are hinting at a Polar Vortex displacement, and that would allow extremely cold air to move into the Southeast beginning next Sunday.

How Cold Are We Talking?

Some models have indicated that low temperatures could push into the negatives digits around WNC, but we are still 8-10 days away from that cold..so a great deal can change. Below you can see the most recent GFS FV3 temperature depiction for Sunday morning. It drops temps into the low teens, with Northwest Flow moisture streaming in off the Great Lakes.

The storm depicted is interesting because its a strong arctic front that pushes through the area. Some models have indicated that it could move farther south, and that leaves the door open to a more wintery solution in WNC. So what you need to know is that I have my eye on next weekend and a strong(more winter like) pattern change that looks to occur. I will be doing a live in-app update at 5:30pm today so be sure to download the app and tune in. I will also be discussing a shortwave front that will move through WNC Thursday into Friday. This front could bring some snow showers to higher elevations locations, so be sure to join me as I cover the possibilities!
