Winter Weather Advisories Much of Eastern Pennsylvania to

Southern New England Monday Night into Tuesday

The first Winter Weather Advisories are up for areas from Maryland northeast into Southern New England. This includes the big cities of Washington DC, Baltimore, Philadelphia, & New York City. Additional Winter Weather Advisories will likely go up for the rest of Southern and Central New England later today. These advisories cover the overnight period into Tuesday.

What is expected to happen is a general 2 to 3 inch snow fall and while the map shows what seems to be a uniform perspective, there probably will be some variations in some some areas. There could be the odd 4 inch amount here and there and on the other hand along the immdediate coast, it could wind up being an inch or less. There are no issues to worry over during today however. We will see sunshine and probably some high clouds coming in later on. Temperatures today in general will top out in the upper 20s in colder areas well inland and mostly lower 30s everywhere else. Radars are quiet for the time being.

Low pressure on an arctic frontal boundary is moving across the South and Southeast US and we do have a large area of Winter Storm Warnings in effect across the Tennsessee Valley and northeast up the Appalachians. Some of these areas could get 6 inches or more of snow but much of that heavier snow accumulation is being helped along by bitter cold temperatures behind the arctic boundary.

Eventually we do see a broad low developing along the Carolina coast that heads northeast but the system doesn’t strengthen very much if at all so we will see spreading northward tonight through New Jersey into Southern New England and the end from south to north Tuesday morning. Most of the snow accumulation will come from this first push. During the day tomorrow we see snow for areas inland for awhile before tapering off and ending.

Colder air follows Tuesday night into Wednesday with lows Wednesday morning in the teens and lower 20s. Wednesday looks to be a nice day sky wise with sunshine but a cold day temperature wise as highs at best will be in the upper 20s and lower 30s. Thursday attention turns to another arctic boundary with very cold air behind it. This allows for a stronger system to develop beginning Thursday night and lasting into Friday night and early Saturday. There are issues with this system as it seems to have a tough time getting going and it doesn’t really develop until it is well offshore.

It does seem that some snow will fall from this later Thursday into early Saturday morning and it will come with falling temperatures through the 20s and into the teens as the last shot of arcric air arrives. I think this system has the pottential to produce some 4 to 6 inch amounts and it will be fluffy powdery snow verses the heavier wet type. Behind it for this weekend is what will be the last shot of very cold which will be here for Saturday into Sunday. Temperatures will drop to the teens and single digits Friday night and highs will only be in the teens to near 20 Saturday. However by early next week, temperatures will be head up into the 40s as a warmer pattern takes over.
