The quiet pattern continues and will last through Friday before some changes take place. High pressure northeast of New England and low pressure far to the southeast will combine to cause a weak to moderate east to northeast flow over southern New England through Wednesday as a weak upper trough moves in from the west. This will promote a variably cloudy sky through Wednesday night along with cool air, but with no precipitation, conditions will be excellent for traveling just before Thanksgiving Day. The holiday itself on Thursday will be a very nice one as a narrow high pressure area builds overhead, and this high will push offshore on Black Friday, resulting in a fair and milder day, conducive to heavy mall traffic and lots of money spending.
The remainder of Thanksgiving weekend will see some changes take place. A strong cold front will approach then cross the region Saturday and Saturday night. A band of rain showers will accompany the front as the air will still be mild ahead of it. But a sharp shot of cold air will come in as the front passes (exact timing remains to be seen but best guess is Saturday evening for the front to cross the region). Most of the moisture will be offshore rather quickly so the chance of snow showers on Sunday is remote, at best. But if any moisture is around it would be cold enough to support snow showers.
Looking into early next week, a fair and cold Monday should be followed by a threat of unsettled weather Tuesday (too early to be sure on rain vs. snow, or the significance of the event).
