Forecast for Monday, December 10, 2012

A warm front will be slowly lifting northward tonight into early on Monday. Periods of rain will accompany waves of low pressure riding along the front. When it is not raining, areas of fog are likely to form. The fog will dissipate on Monday, likely followed by clouds and peaks of sunshine. If the low clouds lift relatively fast, temperatures could take off and approach the upper sixties and lower seventies across the southern portion of our area with sunshine. Towards Mount Pocono, the warm front may have some trouble lifting north of here. Temperatures could be stuck in the forties and fifties if this scenario ends up being the case with fog, showers, and overcast skies. There remains a potential for a temperature bust should this front even fail to lift through the Philadelphia Metropolitan Area. Right now, we believe it will move north of Philadelphia and thus are forecasting a mild day for December standards. 

A strong cold front will move through Monday Night into Tuesday Morning. A pre-frontal line of showers and scattered thunderstorms is likely to develop. Areas that do warm into the upper sixties and lower seventies have the best potential for a thunderstorm. Any thunderstorm could contain small hail and gusty winds. Lingering showers on Tuesday should end in the morning, followed by afternoon clearing. A blustery wind may also be around on Tuesday.  

The cold front stalls out offshore on Wednesday and some energy may develop along this front. It could throw back some clouds, most likely south and east of Philadelphia. There could even be some light showers along the coast. Right now, we are going with sunnier conditions N&W of Philadelphia. Thursday and Friday appear to be dry at this time, followed by another storm system for the weekend.
