Trumbull may get 5 to 7 inches of snow later Saturday and early Sunday, to be accompanied by strong winds and followed by brutal cold.
“Snow and blowing snow, with near blizzard conditions possible,” said the National Weather Service (NWS) when issuing a Winter Storm Watch for Trumbull and all of Fairfield County, in effect from 1 p.m. Saturday to 1 p.m. Sunday.
Sub-zero wind chills are expected at night in the aftermath of the storm.
Here’s a timeline for the coming system and following days in Trumbull from the NWS:
2 P.M. SATURDAY — Snow begins, with about an inch accumulating during daylight. Daytime time of 29 degrees.
AFTER 5 P.M. SATURDAY — Snow intensity begins to pick up, with 2 to 4 inches falling overnight. Overnight low of 13 degrees.
9 A.M. SUNDAY — Snowfall could begin to diminish, then becoming cloudy, cold and windy. Another 1 to 2 inches could accumulate before the snow stops. Consistent winds of 21 to 28 mph, with gusts up to 43 mph. Daytime high of 15 degrees.
SUNDAY NIGHT — Extreme cold, with a nighttime low of 6-below-zero. Consistent winds of 17 to 22 mph, with gusts up to 35 mph.
MONDAY — Sunny, with a high near 16. Overnight low of around 0 degrees.

The brunt of this storm is expected to impact far eastern Massachusetts — including the Boston area — and coastal Maine, where NWS Blizzard Warnings have been issued and more than a foot of snow could fall.
Eastern Connecticut should get more snow than the southwestern part of the state, and Litchfield County may see the least accumulation.
