FAIRFIELD COUNTY, Conn. -- Rain is expected to fall nearly all day across Fairfield County, but as temperatures drop, it will turn to snow late Wednesday as winter keeps its grip on the region, the National Weather Service said.
Coastal Connecticut will be spared the wrath of the storm, which is expected to drop as much as 18 inches of snow across northern New England.
The storm will begin as rain Wednesday, with about a quarter of an inch possible. High temperatures will approach 50 degrees.
Rain and snow showers are expected Wednesday evening, becoming all snow after midnight. Some thunder is also possible. Temperatures will drop into the mid-teens with blustery southeast winds of 13 to 18 mph becoming northwest at 19 to 24 mph after midnight.
The chance of precipitation is 90 percent, with less than a half-inch accumulation of new snow.
Northern Connecticut is under a Winter Weather Advisory from 10 p.m. Wednesday to noon Thursday. The warning does not extend as far south as Fairfield County. But it warns of sleet and freezing rain as well as a flash freeze overnight as temperatures fall.
