The disturbance that produced a trace to two inches of snow throughout the Philadelphia and New York City metropolitan areas is now exiting well out into the Atlantic. High pressure over the Mississippi Valley this morning will be in control through tomorrow with clear skies and relatively mild conditions.
Any snow on the ground this morning will be melted away as temperatures rise into the mid 40's to lower 50's for highs by this afternoon. Temperatures will range from the lower to upper 20's for lows tonight and lower 40's to lower 50's for highs tomorrow.
A disturbance will approach on Friday night from the Mississippi River Valley. This disturbance will begin to interact with an arctic cold front that will approach from the central Great Lakes.
While the two disturbances will interact off the New Jersey coast by early Saturday morning, the overall pattern will continue to support a progressive storm track. As such, while snow is expected on Saturday morning, accumulations of one to three inches with local amounts up to four inches will be expected.
This low pressure system will exit as fast as it enters with clearing skies by Saturday afternoon. An arctic air mass will take hold Saturday afternoon through Sunday with clearing skies and below normal temperatures. Temperatures will range from the lower to upper 10's for lows and upper 20's to upper 30's for highs.
High pressure will remain in control on Monday and Tuesday with moderating temperatures. Another disturbance will approach by Wednesday with scattered snow showers in the morning. Temperatures will range from the upper 10's to mid 20's for lows and lower to upper 40's for highs.
