"The first snowflakes of the season may be seen across northern New England and northeastern New York state, especially in the mountains where some of the ridges and peaks could see a light accumulation from late Thursday to Friday," AccuWeather Senior Meteorologist Adam Douty said.
AccuWeather Global Weather Center – September 20, 2022 - AccuWeather meteorologists say that the strongest wave of cool air since May will arrive across the Northeast just in time for the official start of fall, which begins at 9:03 p.m. EDT Thursday with the autumnal equinox.
During the transition to fall, the sun’s direct rays will pass over the Equator and then continue to move southward as fall continues into mid-December.
And, right on cue, the air will turn chilly enough to send people reaching for long sleeves, jackets and fleeces as lows will plummet into the upper 30s and 40s across the interior and the 50s in many of the Interstate 95 cities from New York City all the way down to Philadelphia, Washington, D.C., and Richmond, Virginia, during the latter part of this week and into this weekend.
Daytime high temperatures will trend downward significantly. For example, in New York City, following highs in the lower 80s on Wednesday, temperatures are likely to be in the upper 70s on Thursday. The temperature drop will be even more noticeable as highs on Friday and Saturday are projected to top out in the 60s. A breeze stirring during the daytime hours on Thursday and Friday will contribute to AccuWeather RealFeel Shade™ levels 10 degrees or lower than the actual temperature.
