First Widespread Accumulating Snow of the Season

The first widespread accumulating snow of the season is knocking on our doorstep in less than 24 hours. Now, before everyone gets too excited (or concerned) this won't be a classic New England nor'easter with high winds and very heavy snow. Rather, we are looking at an overall light event with a couple to a few inches of snow for most of the area. The National Weather Service has already issued a Winter Weather Advisory for coastal Connecticut as well as coastal MA, RI, southern NY and most of NJ. This may be expanded further inland to include all of Southern Connecticut later today.

National Weather Service Advisories

Forecast: Snow breaks out later tonight before midnight, west to east and expands across Southern New England during the overnight hours. Snow will become moderate at times and possibly heavy across the extreme southern coast. Some light rain or rain/snow mix may be possible at the start especially at locations right along the water. We are watching an area of heavy snowfall banding that may make its way into southern Connecticut. For now we are forecasting a general 1-2" for the northern half of the state and 2-4" in the southern half, mostly south of I-84. Areas farther south and east have the best chance for seeing up to 4".

12/13/25 8:30AM Radar & Snowfall Trajectory

With the persistent cold weather we've had for the first half December, snow will accumulate quickly on all surfaces. Untreated roads will become slick and snow covered. The heaviest snow will occur just before and around daybreak and come to an end northwest to southeast mid-morning. Snow should be completely done by noon tomorrow. Cold, dry air moves in behind the system with high temperatures on Sunday only reaching in the upper 20s to around freezing.

While this isn't a blockbuster event by any means, the combination of cold temps and moderate snowfall will make travel somewhat difficult Sunday morning. Luckily this is occurring on a weekend, but if you do plan on traveling use caution and allow for extra time.

Here is our current forecast snowfall amounts for Southern New England, Tri-State Area, Connecticut and New York/New Jersey Metro. This will likely be the final call but if there are any dramatic changes in the forecast we will issue a short-fused update later today or very early Sunday morning.

We'll keep you updated on any changes to the forecast.
