Wednesday: Fog to start, then becoming mostly sunny. Warmer with a high near 75 degrees. Northeast winds will shift from the southeast at 5 to 10 mph. The shore will remain in the lower 60s with extra clouds and fog.
Thursday: Morning fog is possible, otherwise, expect mostly sunny skies. Thursday doesn't look to be as warm as originally thought due to the possibility of early clouds and fog, but we should still finish the day in the upper 70s. The record high is 80 degrees, set back in 1948. Believe it or not, the ECMWF model has a couple of 82-90 degree contours in Maine for Thursday, but it only has a 68-75 degree contour for the Delaware Valley. I think we should at least get into the upper 70s, however.
Friday: Hazy sun with a 40 percent chance of pop-up thunderstorms in the afternoon. Friday now looks to be the day with record warmth, and highs will be in the lower to mid-80s. These very warm temperatures will be caused by the approach of a backdoor cold front, and after the front passes Friday night into Saturday, it will be much cooler for the weekend. The record high for Friday is 78 degrees, set back in 1938.
