Mild Start, then Snow in the Interior Northeast

December 13, 2022 // Article by: Steven Weinstein

November started off on a rather mild and quiet note, but a pattern flip towards the middle of the month then ushered in a colder airmass which featured many frosty and sub-freezing nights. While some areas north and west of the I-95 corridor saw their first flakes of the season, most notable was a mixed and accumulating snowfall event that occurred across the interior portions of the Northeast and the higher elevations of the Berkshires, Poconos, and Catskills during the middle of the month. Drier stretches were also prominent, with a number of smaller rain producing systems closing out November. One such system brought numerous reports of damaging wind gusts across portions of New England.

Despite an overnight system into the 1st, the beginning of the month was dry and pleasant as high pressure dominated overhead. Daily record high temperatures in the upper 70s to the low 80s were also set during this timeframe across many locations, and a few monthly records were even set in Bridgeport, CT and Islip, NY! A weak cold front then brought light rain to parts of the East Coast on the 6th and 7th. This was then followed by a cooler but drier stretch before moisture and the remants of Hurricane Nicole approached from the south, merging with an approaching system from the west.  This system brought a bout of rain to the Northeast on the 11th - 13th. Rainfall amounts generally ranged from 1-2", but gusty winds also occurred across parts of New England that led to spotty tree and power line damage. Additionally, further south across Southeast VA on the 11th, many tornado warnings were issued and funnel clouds sited, with a brief EF-0 tornado even touching down in King and Queen County, northeast of Newtown, VA. The passage of this system marked a major pattern change as much chillier conditions arrived afterwards.

With the colder air in place, this was quickly followed up by another system on the 15th and 16th. While many were actually on the warmer side of this system and saw rainfall totals of around 1", and spots along the Jersey shore seeing 2"+, portions of the Interior Northeast were on the colder side and saw more of a wintry mix and even some accumulating snowfall.  Most notable were snowfall totals of 2-4" in the Poconos, though amounts of 1-2" were also common across much of the Upper Hudson Valley, Northern CT, and the Worcester hills in MA. A quick hitting disturbance on the 18th then brought additional snow showers and even a few snow squalls to the Mid-Atlantic and C, which produced dustings to a few tenths of snow accumulation in spots.  Some dustings of snow even occurred with snow showers extending all the way down into Northern MD.

A generally quieter weather pattern then prevailed throughout the latter part of the month and up until the Thanksgiving holiday, although it remained quite cold at times with many locations setting daily record low temperatures in the teens and 20s on the night of the 21st. A few additional rain makers then closed out the month as temperatures moderated once more. The most notable system was a potent cold front on the 30th, which brought localized rainfall amounts of 1"+ to parts of New England and very strong to damaging wind gusts of 45 - 60 mph. These winds were strongest across portions of MA, RI, and CT where scattered wind damage occurred.

Overall, November finished on a milder note with the average high and low temperatures running 2 - 5 degrees above normal. However, it certainly felt much more like winter at times owing to a pattern shift mid-month and many sub-freezing nighttime lows.  From a precipitation standpoint the month ended with many locations across the Mid-Atlantic and Northeast in a slight precipitation deficit of 0.5 - 1" below the normal. Conversely, portions of Southeastern VA actually finished the month in a slight precipitation surplus, at 0.5 - 1" above the normal values.
