As a warm front continues to lift north towards New England today, variable to overcast cloud cover and areas of fog can be expected.  Well above normal temperatures will be in place through tomorrow with a pleasant yet cloudy preview to Spring.

With variable cloud cover in place and winds shifting to the southwest at 5 to 15 mph, temperatures will rise to well above normal levels for this afternoon.  Afternoon high temperatures will range from the upper 30′s to lower 40′s over the northern interior and mid to upper 40′s throughout the rest of the Philadelphia and New YorK City metropolitan areas.

Tonight, as more warm air invades, fog will redevelop throughout the region.  The fog will become locally dense with visibility falling below 2 miles in many locations.  The fog will create travel problems in the early and mid morning hours.  Temperatures will fall into the upper 30′s to lower 40′s for lows, which are the what afternoon highs should be.  Temperatures will skyrocket tomorrow afternoon under the influence of southwesterly winds at 5 to 15 mph and variable cloud cover.  Temperatures will jump into the mid to upper 50′s over the northern interior and upper 50′s to lower 60′s along the coast.  A few locations may even push into the mid 60′s over the southern Delaware River Valley.

A powerful cold front will put an end to the abnormally warm weather with very heavy rain and strong winds late tomorrow night into Thursday morning.  Widespread moderate to heavy rainfall can be expected on Thursday morning with wind gusts exceeding 40 mph at times.  Rainfall amounts of one to three inches can be expected as the cold front moves through.  Temperatures on Thursday morning will range from the mid to upper 40′s.  Temperatures will hold steady through Thursday afternoon before falling through the 30′s in the evening.

Cold air returns for Friday through early next week as an Arctic high pressure takes hold from the St. Lawrence River Valley.  A series of disturbances will move through the Philadelphia and New York City metropolitan ares with a threat for scattered snow showers each day.  Temperatures will return to near to slightly below normal levels with lows in the mid 10′s to lower 20′s and highs in the upper 20′s to mid 30′s.  The warmest conditions can be expected along the coast.
