Light snow threat returns to northern Mid Atlantic

11/26/12 8:15 AM

Clouds will be on the increase today as an area of low pressure over the southern Plains organizes and races towards the Delaware coast by tomorrow afternoon.  Winds will be from the north at 5 mph while temperatures will rebound into the upper 30’s to lower 40’s over the interior and mid 40’s along the coast.

Clouds will continue to increase tonight on through tomorrow morning with winds from the northeast at 5 to 10 mph.  Temperatures will fall into the upper 20’s to lower 30’s over the interior and mid 30’s along the immediate coast.

By tomorrow afternoon, rain and snow showers will develop and expand in coverage.  The precipitation will be light and will gradually change over to all snow just away from the coast.  Minor accumulations of one to two inches can be expected along the Delaware River and a trace to an inch of snow is expected elsewhere. There is a threat for higher snowfall totals for central and southern New Jersey and southeastern Pennsylvania if some mesoscale or small scale influences come into play, but this threat is low at this time.  The bulk of the precipitation will be between 1 PM tomorrow through 3 AM Wednesday with the best chance for accumulating snowfall after 5 PM tomorrow.  Temperatures will rise into the mid to upper 30’s over the interior and lower to mid 40’s along the coast for highs before the precipitation begins to develop.  Temperatures will fall into the upper 20’s to mid 30’s by tomorrow evening making for slick road conditions.

High pressure will take hold by Wednesday afternoon with clearing skies and winds from the northwest.  High pressure will remain in control through Friday with tranquil weather conditions and below normal temperatures.  Temperatures will range from the mid 20’s to lower 30’s for lows and upper 30’s to mid 40’s for highs.  The warmest locations will be found in urban locations and along the coast.

An area of low pressure will bring the threat for showers on Saturday and Sunday along with warmer conditions for the weekend.  Temperatures will range from the mid 30’s to lower 40’s for lows and upper 40’s to lower 50’s for highs.
