Summary: Cold high pressure will remain over the region today and tomorrow. A cold front will move through tomorrow evening. Low pressure will affect our area Friday and Saturday.
Today will be windy and cold, with highs only reaching the mid 20s. Northwest winds gusting to near 35 mph will make it feel much colder. A Wind Chill Advisory is in effect until noon for areas along and north and west of I-95.
A cold front will slide through tomorrow evening. Scattered flurries will be possible during the afternoon and evening as the front passes through. Highs will be in the low to mid 30s.
Thursday will be the “calm before the storm” with highs in the mid 30s under mostly sunny skies.
Low pressure will be approaching the area from the southwest on Friday. Every major model has been in agreement for several days now that this storm will pass by to our southeast and produce significant snowfall in our area. While the exact track is still unknown, it is becoming increasingly likely that most of the state will see heavy snow, developing Friday morning and lasting into Saturday evening.
Here is the 6z GFS, used to illustrate the potential timeline of the storm:

As with every major winter storm, the exact track will determine the rain/snow line, the axis of heavy snowfall and any icing possibilities. These details will be worked out over the next two days, but be prepared for a high impact event that will feature heavy snow, strong winds, coastal flooding and possible ice accumulations that will cause disruptions not only for our area, but for a majority of the northeast as well.
I anticipate having a first call snowfall forecast map posted by tomorrow evening and will post intermediate updates on Facebook, Twitter and Google+.
