From WxSouth on Facebook.
The Plot thickens. The European Model (and now GFS too) continue to show a strong piece of energy dropping in behind the initial rainfall in the Southeast Thursday night. At the same time this is going on, a new piece of the Polar Vortex is plunging due south through Wisconsin Friday . Its a strange setup, and a testament to the new strong Ultra-Ridge in the Western Part of North America. If that ridge builds so tall, the tables turn quickly for the Eastern States, with a Snowstorm coming up the East Coast. Right now though, this is so complicated and has timing issues of the various pieces, the models can hardly resolve it this far out.
But I'd keep informed of the weather along the East Coast, from Georgia up the East Coast for Thursday night and Friday. I have much more breakdown on the temperature profiles, moisture transport, and question how far west to pull the moisture in the Cold air at wxsouth.com.
The chances are growing though for the first snow flakes of the season for part of NC, Virginia and further north....followed by a slug of intense cold air (which has it's own snow seperately in TN, KY, WV) on Friday night and Saturday. Trends on models will mean everything from this point on, as anything is possible, from full phasing, to a nudge eastward, but the map below shows the area I'm watching.
