Discussion              

A messy day is in store for the region with a snow/rain combination and sleet can join the mix at times. Precipitation will overspread the area this morning and temperatures will drop from early day highs in the lower 40’s into the middle 30’s and they should remain there for the remainder of the day. Small accumulations of snow are possible of a coating to an inch or two; primarily, on grassy surfaces in suburban locations to the north and west. However, in some of the higher elevation locations to the far north and west (e.g., western Chester, western Montgomery and Upper Bucks) perhaps 2 or 3 inches can accumulate on grassy surfaces. Low pressure will push from the Tennessee Valley early today to southeastern Virginia and then to a position out over the open waters of the western Atlantic Ocean by later in the afternoon.

Looking ahead, it looks like there will be a very active cold frontal passage early this weekend. That next strong cold front will come with pre-frontal rains and possible strong thunderstorms and post-frontal extreme winds are likely as is a changeover to accumulating snow across interior sections of the Mid-Atlantic/NE US. In fact, there is the possibility for some post-frontal accumulating snow all the way down into the I-95 corridor and even as far east as coastal sections of the northeastern quadrant of the nation. Very cold air for this time of year will envelope the entire region for the Saturday night/Sunday time period.
