March 31st, 2012 Forecast

A somewhat normal spring week is ahead as temperatures return to close to normal.  The next issue on the horizon would be precipitation.  While not officially in a drought watch or warning, the Philadelphia area is already over 4 inches below normal, mostly accounting for the lack of snowfall melt missing from the winter months.  We'll get some help this week, as a few unsettled days leave the chance of rain.

The first of those rain chances comes tonight.  Skies will gradually increase in cloudiness with rain showers moving in from west to east after about midnight.  Temperatures around the Philadelphia Metro will remain fairly mild, in the mid-40s.  The showers will carry over into Saturday morning, however by midday, the majority of the precipitation should move off.  Skies will remain mostly cloudy, and winds might be gusty for a period of time long the shore. 

Sunday, temperatures will be warmer with more sun and less clouds.  However, there is a lingering chance of showers as a quick moving high pressure system dives to our south.  This gives a low pressure the chance to move easterly, just to our north.  This weak low pressure will drag a cold front through the region Sunday night.  While this front lacks moisture, there is still a chance of showers associated with it's passing, especially to the north.

As the front moves off, temperatures rebound nicely on Monday.  From there, weather computer models have a differing of opinion as to the timing and strength of the next system to come in.  Timing is from Monday night into Wednesday, and the strength could be anywhere from scattered showers on one day to steadier showers on Tuesday with scattered showers on Wednesday.

The latter half of the work week looks calmer.  Temperatures Thursday and Friday look like their hovering just at the 60-degree mark with partly to mostly sunny skies.  Friday night the next systems look to toss a few showers in towards evening and in to the weekend.
