An active weather pattern is developing for the Philadelphia and New York City metropolitan areas that will bring rain and snow to the region.
For today, a stationary front with waves of low pressure will produce periods of rain through this afternoon. As the low pressure systems consolidate off the New Jersey coast this afternoon, the stationary front will drop south as a cold front with colder air moving into the region. As a result, temperatures will fall from the morning highs of the 50's into the 30's and 40's this afternoon. Most locations can expect a chilly rain, however for locations above 1,000 feet in elevation, rain will mix with snow at times with minor accumulations on cold surfaces.
Tonight, the low pressure system will exit and high pressure will take hold with clearing skies and falling temperatures. Temperatures will fall into the upper 20's to upper 30's for lows tonight and then rebound into the mid 40's to lower 50's for highs tomorrow. Temperatures will average well below normal for this time of year.
A stronger area of low pressure will approach the northern Mid Atlantic on Saturday morning with rapidly increasing clouds and periods of moderate to heavy rainfall expected. As the low pressure system moves over the New Jersey coastal waters, periods of heavy rain and windy conditions can be expected. Meanwhile, for elevations above 1,000 feet, the rain will mix with and change over to snow with accumulations of 1 to 4 inches with locally higher amounts possible. Temperatures will remain well below normal with lows in the mid 20's to upper 30's and highs in the upper 30's to lower 50's.
High pressure will return once again for Sunday and Monday with clearing skies, dry conditions, and below normal temperatures. Another area of low pressure will bring the threat for periods of rain for Wednesday as well. Temperatures will range from the mid 20's to mid 30's for lows and upper 40's to upper 50's for highs.
