NEW YORK [WABC] — A combination of two weather systems will roll into the Northeast and Mid-Atlantic States later today and tonight.

The feature which is the stronger of the two, a low pressure system, is destined to slide along the Southeast Coast and exit the East Coast late tonight via the Carolinas.

The so-called ‘weaker’ feature is associated with an impulse of jet stream energy which is now sliding across the Midwest and into the Great Lakes region.

As mentioned yesterday, these two entities will be competing with each other for moisture, and the southernmost wave is going to be the one that will be able to churn out the most precipitation — which will be getting distributed over Virginia, southern portions of the Delmarva Peninsula and in the Carolinas.

But nonetheless, the consensus amongst the recent U.S. based models reveals that there will be as much as 0.05″ of liquid that will fall on the Tri-State Area late tonight and tomorrow morning.
Assuming all of this is snow, it appears that many places will get a fresh coating to perhaps as much as a full inch.

This may cause some headaches just prior to tomorrow morning’s rush, and untreated surfaces may become slick in a hurry.

So, folks should be prepared to allow extra travel/commute time for tomorrow.

Our maps will reveal that this general ‘coating to an inch’ can happen almost anywhere, although we would not be too surprised if some communities in central or South Jersey had a little more than an inch.

As that low pressure system in the southern branch of the jet stream heads out to sea early tomorrow, it will be leaving behind the upper-level feature, which will be lagging behind in the eastern Great Lakes.

At this point, it appears that any prolonged period of snow associated with that will be confined to upstate New York tomorrow afternoon, while our skies become partly sunny.

Dry weather should prevail tomorrow night and Thursday, and then the focus of our attention will be turning to Friday and Saturday.

Last night’s model output (especially of both primary U.S. based models and the European) is starting to look a bit more like those solutions that the Canadian/GGEM have suggested all along >>> a low pressure system in the South will reach the southern Appalachians before it dies out.

But a secondary, coastal storm will develop and it will rapidly gain strength on Saturday.

While the Canadian is still the most “bullish” on a significant snow storm all the way up to southeastern New York State this weekend (it projects a 972-millibar low pressure system about 75 miles east of Atlantic City early Saturday night), both the G.F.S. and the European are starting to indicate that precipitation will probably occur farther north than what these models were indicating yesterday.

There’s still a lot of time to watch, but we want to at least see more consistency and consensus-building before we make a guarantee that there will be a ‘plowable snow’ around here this weekend.
