Good Morning,

The workweek is getting off to a dry and chilly start this morning... Since late last night, the satellite imagery has been showing a band of clouds associated with some warmer air aloft spreading out across upstate New York and central/southern New England...

Conversely, areas which are located farther to the south have been mostly clear, which is allowing the temperature to drop into the 20s in parts of southern New Jersey, southeastern Pennsylvania and Maryland early today... It’s not very often that you can say "Baltimore is colder than Binghamton", but today is starting out just that way...

There will be a decent amount of sunshine today, and it won't be as chilly as yesterday was... Most temperatures will be in the mid and upper 40s this afternoon...However, while a high pressure system will bring us dry weather today and most of tonight, there is 'trouble just around the corner' waiting for us tomorrow...

A low pressure system that will be developing in the Tennessee Valley later today will begin to streak eastward into the Carolinas by early tonight... This wave of low pressure, albeit weak and moving at a fairly quick pace, is expected to spread a shield of precipitation as far north as southern New England by early tomorrow afternoon...

At this juncture, it looks like the swath of the heaviest precipitation will develop late tonight in the panhandle regions of West Virginia and western Maryland and stretch out to the east tomorrow along the I-81 corridor... This would imply that Hagerstown, Maryland, as well as Harrisburg, PA and most places between Philadelphia and the Poconos (as well as interior sections of northern and central New Jersey) will get a period of wet snow tomorrow that will accumulate an average of 1-3 inches...

While most of this will accumulate on non-paved surfaces, there is still a concern that in those places where snow begins close to daybreak tomorrow, some slick conditions may prevail...

Along the I-95 corridor, which includes the bigger cities and most coastal communities, the models are all suggesting that temperatures in the boundary layer will be 'marginal' for snow — in other words, these places are more likely to see snow occur briefly tomorrow morning "at the onset of precipitation" before it mixes with rain, or it could start off either as a period of plain rain, or a "wintry mix"...

Either way, it appears that the bulk of the precipitation will be occurring during the daylight hours, and the quantitative amounts are expected to average 0.10" - 0.20" in the Tri-State Area, with the highest amounts probably focused squarely on western and central New Jersey...

All of this precipitation should briefly change over to snow tomorrow afternoon, and then end as flurries early tomorrow night... Therefore, some wet roads and sidewalks could become slippery tomorrow night if they are untreated, with most low temperatures expected to be near or below freezing...

There will be a small, slushy accumulation of snow tomorrow in the Tri-State Area... While most of this will occur during the daytime, and paved surfaces will just be wet, grassy surfaces and car tops can get as much as 3 inches in some northern and western suburbs...

The pattern becomes much less complicated during midweek... Although it will be chilly, that wave of low pressure should be racing out into the Atlantic Ocean by early Wednesday morning... In its wake, there will be some sunshine for both Wednesday and Thursday, and temperatures will be in the lower and middle 40s for the most part... Friday is also looking dry...

Have a good day!!!
