January 10th, 2012 Forecast

The weak southern system that is spreading some showers of rain and snow across the Mid Atlantic will scoot away tonight, with sunny skies returning for all on Tuesday.  Those of you north of the Turnpike were wondering about "what southern system" since the sun was out for much of the day in the burbs as well as in the city from time to time.

The nice weather won't last unfortunately as a storm system moves in late Wednesday, continuing into Thursday with a period of rain that could be heavy at times late Wednesday night and early Thursday morning.   That storm system will then usher in a colder pattern for the end of this coming week and the weekend, with a persistent round of chill ahead.

Tonight:  Precipitation is possible until about 10 or 11 PM for those generally south of Philadelphia.  It wouldn't surprise if a coating of snow accumulated across parts of New Castle County into the Pinelands after sunset but anything of substance is highly unlikely.   Clouds linger around for much of the night, with clearing expected towards morning.  Lows in the 20's in the coldest spots, low 30's in the city with light winds.

Tuesday:  Skies will quickly go mostly sunny during the day and it's shaping up as a nice January day.  Highs get to upper 40's north of Philly, around 50 in the city, low 50's south.  West breezes at 10 mph could occasionally nudge higher but with sunshine it won't feel too chilled out.

We'll update more on the Wednesday night storm tomorrow but the cliffs' notes version is generally a rain event with the potential for over an inch of rain for much of the Delaware Valley.  Temperatures will moderate Wednesday night as the storm moves into the region, with mid 50's possible Thursday morning as a steady if not heavy rain falls.
