Synopsis: The front that pushed through the region today will move completely out of the picture in the coming hours. Drier air has spread in its wake and will keep conditions traquil until another feature comes into play on Thursday. Showers and a stray thunderstorm can be expected with the passage of another frontal system. The weekend is setting up to be a wet one, with te approach of a deepening trough.
Short Term: A cold front passed through the area today, and looks to be almost completely out of the picture. The front did not rid us of this warm muggy airmass, as temperatures and dew points remained almost unchanged after the front passed. Some cloudiness still exists in western portions of the state, though points east have cleared out nicely. Stubborn cloudiness will leave as well by sunset, leaving partly cloudy skies overnight for just about the entire state. This allows for some radiative cooling. Unlike the warm, uncomfortable temperatures the commonwealth experienced last night, temperatures look to dip into the lower 60's for tonight. A frontal system will approach tomorrow, one that is not very well represented on model guidance. Timing looks to be late afternoon into evening. A few showers and thunderstorms can be expected out ahead of the front, but nothing too serious.
Long Term: A weak area of high pressure will squeeze in behind a departing front. This will leave Friday to be a quite day, weather-wise. Upper level flow will shift to the SW Friday night into Saturday, ahead of a deepening upper level ridge. There is good model agreement that a strong cold front will move through Saturday evening. Strong storms and rain will be the main threat with this. Unlike the front today, this will bring a dramatic change in air mass. There is also good agreement that the eastern seaboard will see a prolonged period of pleasent and dry conditions next week!
