I have been referring to today’s weather conditions as “classic autumn weather”. The day began clear and crisp with the low angle, early morning, sunshine enhancing the fall colors. A large area of high pressure stretches up and down the East Coast. It is responsible for this weather and it will pretty much remain, in place, until a cold front crosses the area on Thursday. But there will be a couple changes before the cold front arrives.

First a warming trend will get underway tomorrow and continue until cooler air arrives on Friday. But the other change may be more noticeable. There will be a shift to easterly and northeasterly winds for the next two days. This will bring the air flow directly from the Atlantic ocean. Not a strong enough flow to suppress air temperatures but enough of one to promote the development of more cloud cover than sunshine.
By Thursday, ahead of the front, southerly winds will develop. This swing in the wind direction will boost temperatures on Thursday well into the 60s, under partly sunny skies.. But as mentioned above, a cold front later Thursday will put the skids on the warming trend. The front will likely cause scattered showers to develop across the region, as well.
