SHELTON STORM: From 4 to 8 inches of snow possible late Sunday into Monday

SATURDAY 5:15 P.M.:  The National Weather Service (NWS) has issued a Winter Storm Watch for northern Fairfield County, and a more severe Winter Storm Warning for the northern part of Connecticut.

The Winter Storm Watch is in effect from late Sunday night to Monday night, with the NWS saying 4 to 8 inches snow plus a thin layer of ice could fall during that time period in northern Fairfield County as well as northern New Haven County.

The precipitation will begin as a mix of snow and freezing rain on Sunday afternoon, then change to all snow and pick up in intensity at night.

Northern parts of Connecticut — such as Lichfield and Hartford counties — could see 9 to 18 inches, from early Sunday afternoon into late Monday, according to the NWS.

Shelton: Wintry mix and snow to add up

In Shelton, the NWS said there's a chance of snow and freezing rain on Sunday, with sleet mixing in during the evening, changing to all snow late at night. From 1 to 3 inches of snow could fall overnight.

The snow will continue on Monday, switching to a wintry mix in the afternoon. Another 3 to 5 inches of snow could fall by the time the precipitation ends about 9 p.m. on Monday.

The latest NWS forecast represents an intensification of the storm for Shelton and most of Connecticut, although temperature will play a big role in how much snow actually accumulates in specific locations.

Temperatures in Shelton will fluctuate from the high to low 20s on Sunday and Monday, although sleet and freezing rain are still expected at times, the NWS said.
