Forecast for Monday, September 24, 2012

The coldest night in months is expected tonight. There is the threat for some frost in the Pine Barrens and in the typically colder locations North and West of Philadelphia, especially the Pocono Mountain area. Lows tonight in the Pocono Mountains will definitely drop into the thirties. The Pine Barrens may briefly drop into the thirties, but for the most part this area should stay barely above 40 or 41 degrees. The city tonight of course will be the warmest locale, but even here the temperature may drop below 50 degrees for a few hours around dawn.

Monday and Tuesday look great with plenty of sunshine. A few clouds may move in by later on Tuesday as a warmer air begins to flow up from the south in response to an approaching cold front that will arrive on Wednesday. On Wednesday, this front could create some showers and thunderstorms in our region with gusty winds. At this point, it appears this front should clear the region by early Thursday leaving us with clear skies by daybreak.

Another series of fronts and associated low pressure will impact us this weekend, although there isn’t much agreement in the overall setup. Without much agreement, I decided not to get too fancy by just forecasting mostly cloudy skies and rain showers.
