Light Snow Coming Tuesday...Winter Storm Post Christmas?

We are monitoring another light snow event approaching Connecticut. Like the Sunday storm last week, we will see some more light accumulations. The early onset of snow is likely to result in school closures and/or delays throughout the state, mainly inland. The immediate shoreline and lower elevations along I-91 may have a difficult time accumulating snow, therefore we don't expect closures here, possibly delays.

Northeast Overview for Tuesday, December 23rd

Tuesday Details:

Snow is expected to begin early Tuesday morning, arriving between 4 to 8AM across the state. Snow will first enter SW CT and spread northeast through the early morning hours. Snowfall will persist throughout Tuesday, tapering off between 1 to 5PM. Temperatures are anticipated to rise above freezing in most areas, excluding higher elevations above 500 feet. Roads should be primarily wet by Tuesday afternoon.

Snow accumulation will be significant enough to require plowing in most areas away from the shoreline and especially in hill towns. The highest amounts will occur in inland SW CT, NW CT and NE hills. There is the possibility some localized areas may receive more than 3" but it will be the exception. We expect most towns to fall in the 1-3" range. If you are near the Coating-1/1-3" line expect around an inch of snow. The immediate shoreline may struggle to accumulate any snow at all on paved surfaces with temperatures in the mid-30s.

Regarding the likelihood of a White Christmas:

Officially, a White Christmas is defined as having 1" or more of snow cover at 7AM or snowfall accumulating 1" or more during the calendar day. The likelihood of this happening is almost 100% if your area receives 2" or more of snow on Tuesday. Temperatures on Wednesday, Christmas Eve, should reach in the upper 30s to around 40. This will result in some snow melt but with the very low sun angle this year, it won't be much.

Immediate Shoreline: No White Christmas. Less than 1" is expected here and should melt completely on Wednesday.

Inland a few miles and 91 corridor: Possible. If the system ends up slightly colder and snowier than expected and 2" accumulates, a white Christmas is likely.

Inland Hills above 500 feet (SW/NW/NE CT): Very likely. 2-3" on Tuesday and cool temperatures on Wednesday will help retain the snow.

Boxing Day Winter Storm:

We will have a two-day respite from winter weather on Christmas Eve and Christmas Day, but a winter storm is beginning to show up on computer models. Right now models are trending south with the system, so an all-snow event is possible. If models continue the trend, the storm may miss completely to our south. On the other hand if the storm tracks farther north, a wintry mix of snow, ice and rain is possible. At this point it's too early to tell with the system over 4 days out and models still working out the details.
