We will enter the weekend with little change in our weather pattern, but changes will arrive by late Sunday. It looks like we will wake up Saturday to low clouds again due to the onshore moist flow from the Atlantic, but clouds will burn away around midday. There will be some local midday and afternoon thunderstorm development along the sea breeze front as it pushes inland, but the chance of rain is only about 25% at most on Saturday, and much less than that near the Atlantic beaches. Highs will reach the mid 80’s inland, but the coast will see only the mid 70’s, with winds from the south at 10-20 mph in the afternoon.
Sunday will be much the same, but after 3 PM the rain chance will begin to climb as a cool front approaches from the north. It now looks as if this front will arrive later than expected earlier, and I think that the Dover races will likely be dry. There is some concern for a thunderstorm after 3 PM Sunday afternoon. Evening thunderstorms are also possible, and it will be cooler, with widespread rain and thunder Monday into Tuesday as the front passes. It will turn cooler Monday and and a strong onshore flow will develop by later Monday, bringing beaches down to the low/mid 60’s at best.
The NOAA 5 day rainfall forecast is below, and you can see we will see some much needed rain, most likely from late Sunday into early Tuesday afternoon.
