When is the snow expected to arrive and how much?
The biggest concern over the latest winter storm to affect Connecticut is not how much snow we’ll get, but when it arrives.
Because the snow will be falling during the afternoon/evening commute, there is a Winter Weather Advisory starting at 2 p.m. Wednesday.
The advisory means that periods of snow, sleet or freezing rain will cause travel difficulties.
“Expect slippery roads and limited visibilities, and use caution while driving,” the NWS says.
When will it start and end?
Precipitation will be very close to the region and with chances beginning to increase for snow late this morning.
However, the best chance of snow beginning is after 2 p.m.
“The snow will become more widespread this afternoon from SW to NE and is expected to become a moderate steady snow,” according to the NWS forecast discussion. “Temperatures will be below freezing and will allow for 1-4 inches of snow to accumulate with potential for snow to be 1-2 inches higher than forecast if snow becomes heavy for prolonged periods of time.”
Southwest Connecticut will see snow from 3 to 8 p.m. with about 3 inches forecast for the I-95 corridor and the Merritt Parkway. The best chance of snow is between 5 and 8 p.m.
From 8 to 11 p.m., sleet or freezing rain is forecast with .06 of an inch possible.
As temperatures rise into the mid-30s early Wednesday morning there will be a change over to plain rain.
Colder temperatures in northern Connecticut will see mostly snow with some freezing rain and sleet. Temperatures are expected to rise above freezing in northwest Connecticut by 6 a.m. Wednesday.
How much snow/ice is expected?
The NWS’s total snow accumulations is between 1 to 3 inches with a light glaze of ice expected.
Highest snowfall totals across the state are expected in western Connecticut with 2 to 3 inches from southern Fairfield to northern Litchfield counties.
Towns like Greenwich, Stamford and New Canaan could see 4 inches from the storm that is tracking south of Long Island.
Most coastal areas expected to have a glaze with ice amounts under a tenth of an inch farther inland with a longer period of freezing rain expected inland.
What are Connecticut meteorologists forecasting for snowfall totals?
NBC Connecticut: Coating to 2 inches.

WTNH: Coating to 2 inches.
Fox61: Coating to 2 inches.
News12 CT: 1 to 3 inches.
What will the temperatures be?
Because temperatures will begin to rise after midnight, no flash freeze is expected, especially in southern Connecticut.
On Wednesday, temperatures are expected to reach a high into the upper 40s or low 50s in the afternoon.
By dawn Wednesday, the shoreline will have temperatures around 33 degrees. Inland Connecticut will have temps below freezing.
From Thursday night to Tuesday, temperatures will fall back into the upper 20s inland and the lower 30s closer to the coast.
High pressure returns early next week with dry conditions and a gradual return to near seasonable temperatures.
