While we were expecting to celebrate the return of the sunshine to our skies today, that celebration was unfortunately delayed for most of us. While much of New Jersey saw at least some sunshine, an obstinate overcast, and even a brief shower or a few sprinkles hung over much of eastern Pennsylvania throughout the day. The stubborn clouds refused to budge, and temperatures once again were stuck in the 40s for the fifth straight day. Our average high for mid-November are in the mid-50s, so the cooler than average pattern continued yet another day. In fact, today was our eighth consecutive day of below average temperatures.

November can be notorious for persistent clouds, due in part to the low sun angle this time of year that is too weak to burn through the low-level moisture and deck of stratocumulus clouds that results. However, if at first, you don't succeed, try again. As a weak area of high pressure builds in overnight into Wednesday, we'll try to bust more breaks in the clouds into tomorrow.

The clouds that lingered through Tuesday evening will break enough to allow temperatures to drop into the upper 20s overnight. The sprinkles that we experienced in spots during the afternoon and evening hours on Tuesday have ended, but that patchy fog overnight may be enough to have you throwing on your windshield wipers.

Wednesday will be a dry day with partial sunshine overhead. Temperatures will crawl toward 50 degrees during the afternoon. Clouds may increase towards evening ahead of a cold front, one fairly lacking in terms of moisture ahead of it and cold air behind it. However, that front will be enough for some extra clouds and a few rain showers later Wednesday night. Due to the clouds, it will be much less cold Wednesday night as low temperatures remain closer to 40 degrees.

Clouds will again try to break for some sunshine on Thursday in the wake of the cold front's passage, although a rain or even a Poconos snow shower may still pop up or linger. It will turn increasingly windy on Thursday, as winds may gust over 30 miles-per-hour as a modest shot of slightly cooler air arrives for the end of the week. Friday may finally be the day we see those coveted and difficult to attain mostly sunny skies, although it will be brisk and cool sunshine with highs in the mid to upper 40s.

Our next weather maker arrives to start the weekend, as a warm front will approach and produce some clouds and occasional showers for at least part of the day on Saturday. The temperature forecast is tricky, because some mild air will lurk just to our south on the warm side of that front. However, it's unclear just how much if any of that warmth we can tap into. Likewise, just how much of the day will be wet will be determined by the location of that front on Saturday.

Next comes the cold front, which is expected to sweep through the area later Saturday night. Ahead of that front will come another chance for some showers, and if there is any warmth around, perhaps a rumble of thunder. Behind this cold front will be a more sizable shot of colder air, which will ride some blustery breezes into the area early next week. 
While colder than average, the forecast does look mostly dry early next week with no major storms in the near future. Another reinforcing shot of cold could also be in the cards towards Thanksgiving, which right now also looks to feature below average temperatures. There are early signs of some unsettled weather by the end of Thanksgiving week with a chance of rain or snow, but that's still a bit beyond the reach of the seven-day forecast.
