Snow Tuesday As Upper Air Disturbance Swings In From The West

We are basically in between 2 weather systems here in South Central Pennsylvania and North Central Maryland. There is a coastal low to the east and an upper air disturbance to the west. Between the 2 systems we will be sitting and clouds and some breaks of sun today with highs into the 40s. The map below shows the snow forecast for our area. The system to the east will have no impact. The system to the west could produce a coating to a couple of inches on Tuesday.

You can see on the satellite picture below the clouds with the low to the east are offshore and then we have the clouds around the Great Lakes with the second system.

The coastal low will impact Long Island, Coastal Connecticut, and Coastal New Jersey. The back edge should reach about NYC overnight into Tuesday morning. Then the western system comes across on Tuesday and produces a coating to an inch or so from the city west. Temperatures tonight will settle in the upper 20s and lower 30s and highs Tuesday just in the low to mid 30s. Skies should clear Tuesday night with lows in the teens to low 20s and Wednesday will be sunny but cold with highs just into the 30s.

Another front with another wave will be approaching for late Thursday. This system continues to look less and less impressive as we get closer and closer to it. For now we we will call for clouds arriving Thursday with highs in the 40s. The some rain that changes to snow Thursday night into Friday but again this doesn't appear to be anything to be overly concerned with. Another shot of cold air follows for the weekend.

NATIONAL WEATHER SERVICE SNOW FORECAST MAPS FOR ALL OF THE NORTHEAST AND MIDDLE ATALNTIC STATES ARE UPDATED AND POSTED HERE ON METEOROLOGISTJOECIOFFI.COM THESE MAPS UPDATE AUTOMATICALLY THROUGHOUT THE DAY.
