Synopses
Today, the northerly flow keeps the entire northeast below normal for temperatures today. Clouds and snow showers push in on Wednesday when the first piece of energy comes up from the south. The remainder of the energy gathers itself Friday and could ride up the coast as a nor'easter. It is looking more likely that there will be a storm, but exact track is still very uncertain.
Short term
Our entire state should be sunny but cold today since we are under the influence of the eastern side of a large high pressure system and its accompanying northerly flow. Wednesday, energy starts to build along the gulf coast and an initial piece looks to break of and head north. This initial storm doesn't appear very strong and the ridge of high pressure should remain strong enough to keep it mostly to our south. Southern regions of our state should see some snow or perhaps even rain showers.
Long term
On Thursday, clouds remain prevalent across the state. The remainder of the energy along the gulf coast starts to organize and move up the eastern seaboard. Friday could be interesting day weather wise across Pennsylvania and the entire northeast. This is beginning to look like it could be a classic Nor'easter. Models vary on track and strength with the GFS taken the most aggressive stance, showing a very potent low right along the coast. If the low stays farther off shore, eastern regions will see the bulk of the precipitation; rain to snow and rain along the immediate coast. If the low tracks further west, the axis of heavy snow shifts westward into central and western pa. Eastern Pa would probably see mostly rain in this instance. In any case, the storm system deserves close attention over the coming days. By Saturday, all precipitation should have wrapped up leaving us with lingering clouds and a fresh shot of cold air.
