Scenario maps for possible weekend storm



These are the scenario maps for this weekend's possible storm. Scenario A shows a moisture loaded low comes out of the Gulf of Mexico and turns into a full blown Nor'Easter I would put about 45% confidence into this happening at this point. Scenario B shows a storm come out of the Gulf and head NE OTS because of two supressing HP's and that gives no one north of virginia anything, and NC mountains end up with Ice and/or Heavy snow, I would put about 35% confidence in this happening and the other 15% into maybe and appalachian mountain runner and 5% on no storm for anyone at this point.

Possible Weekend Northern Mid-Atlantic Winter Storm


Ok so this is what is going on, We have a couple of factors from keeping this a widespread Major Snowstorm, First off is the track, The track is going to be influenced by a High pressure placement. This storm is going originate in the Gulf of Mexico and it is going to gather a LOT of moisture. What I think is going to end up happening is, there is going to be a storm that heads toward the appalachian mountains and will eventually transfer its energy to the Virginia coast spreading heavy rain from Eastern Texas to louisianna and up to Southern Virginia, at which time it transfers its energy to the coast and spreads Ice and rain up the coast to NYC while spreading Heavy snow inland from NNJ to Central PA but snow all the way to eastern Ohio. Problem is, is that according to the models there is going to be a high pressure right near Boston,MA but it is not strong so for anyone south and east of Allentown, PA will end up being rain and/or Ice. Thats all that I have right now, as for most storms nearly a week out there is a lot more questions than answers and on wednesday I will probably do another update on the storm.

6:40 p.m. Second to last Snow map for Clipper January 7th-10th



Here is my second to last snow map for the Alberta clipper that will cross the country and affect the mid-west and Mid-Atlantic. A clipper that is currently affect montanna will cross the country over the next 48 hours and will drop advisory level snow across the PA, WV, NW NJ, MD, DE. Although there is not going to be a lot of qpf, there will be rather high liquid to snow ratios at a clip of 20-30:1 across the Northern Mid-Atlantic.
