Christmas Day Update:
Good afternoon and Merry Christmas! While Santa didn't bring any snow for Christmas Day this year, he does have some in store for tomorrow. Over the past 24 hours models have bumped the storm north a bit which brings heavier snowfall farther north and east into Connecticut. We have updated our forecast to reflect the latest trends and our current thinking. The area 4-8" has now pushed about 30 miles to the northeast covering most of central and western CT. The 2-4"/1-2" area was also pushed east accordingly.
Details:
The National Weather Service has issued a Winter Storm Warning for all of Fairfield, New Haven and Litchfield counties for 4-8". Winter Weather Advisories were issued for Hartford and Middlesex counties.
Snow breaks out in far western Connecticut tomorrow night just after dark between 5-7pm. Snow quickly spreads east and covers the entire state by around 8-9pm. There will be a small 2-4 hour window of moderate to heavy snow from 8pm to around midnight. Thereafter, heavy snow breaks down and becomes light to moderate. Temperatures will be cold in the 20s and upper teens so snow will stick to all untreated surfaces very quickly. Light snow will taper off just before daybreak and should end completely by 7AM. Saturday will be cold with temperatures only reaching to around freezing.

Wednesday 7PM Update:
Our forecast for Friday Night into very early Saturday is on track. Evening models are consistent with showing a plowable snowstorm for the majority of Connecticut with the focus on southwestern areas. We've seen a slight bump north in model trends this evening which may mean more snow farther north and east. However, with uncertainty amongst all the models and general spread, the forecast remains unchanged. We will issue a final update suite of maps and a blog post like tomorrow evening. If there are any drastic changes we will be sure to let you know!
Original Post:
Season's Greetings! We are monitoring another winter storm targeting Connecticut and the NYC Metro area. This storm is expected to be significantly colder than the recent slushy conditions from Tuesday, with no anticipated rain/snow line.
A Winter Storm Watch is currently in effect for the NYC Metro and Fairfield County. We anticipate that this watch or an advisory may be extended to include Litchfield and New Haven counties. A watch is issued when snowfall of 6 inches or more is expected, while an advisory is issued for expected snowfall of 3 inches or more.
This storm will approach from an unusual direction, moving from northwest to southeast, contrasting with the typical southwest trajectory of storms. Snow is projected to begin in the western part of the state between 5-7 PM and will progress slowly eastward. During the hours between 9 PM and 1 AM, the snow is expected to intensify, with snowfall rates reaching 1-2 inches per hour within a specific band. Areas within this band could see accumulations of 6 inches or more, while regions to the east of the band may experience significantly less snow. The snow is expected to conclude by daybreak, with the primary weather concern thereafter being cold temperatures and wind chills approaching zero at times.
Snowfall amounts will generally increase closer to Fairfield County, potentially exceeding 6 inches. In contrast, areas closer to the northeastern corner of the state may only see a light coating to an inch. The precise location of the heavy snow band is crucial for the forecast, and any deviation from current projections could result in forecast adjustments. Wishing you and your loved ones a Merry Christmas! Our final update will be provided on Christmas evening.
