6pm fast update 12/7/17- What is going on..Snow expected

 Model data has trended to a more snowy look.

Why?

1.Low in the Gulf was progged to head NE to a spot off the NC coast but be weak. A Clipper system and it's upper air energy didn't look to interact much. The model runs that showed snow had some level of interaction

2. Last night ALL data trended away from a low being close enough for snow.

3. Noon data showed more interaction or phasing between the clipper system over The Great Lakes and our storm in the Gulf. The result is a slower system that is stronger ( Maybe sub 1000 mb east of Hattaras)

4, Snow may be in southside mid morning, up to 460 by mid afternoon, but that's just the teaser.

5. The bulk of our accumulating snows will come overnight into Saturday. There may even be a lull the bulk of Friday evening.

Best guess
East of 81 Roanoke to Lynchburg 2-4
Southside  3-6. (Martinsville, Danville
West of 8 1 1-3

If the trends continue, we could up those especially in the Roanoke and Lynchburg area.. and at some point mixing could be an issue in Southside areas.

Please share this with family and friends.


Rapidly changing data.. expect a ton of data tonight.
