WFSB 3 TV forecast details

WFSB 3 TV chief meteorologist Mark Dixon with Jill Gilardi said, "Snow develops across Connecticut around and after sunset on Saturday. By 8 p.m., steady snow will falling across most of the state. This will be a period of steadier, heavier snow and coincides with strengthening wind gusts.

"Travel will be impacted...so if your Saturday evening plans take you out of the house, expect roads to deteriorate quickly after sunset," Dixon and Gilardi said. "The steady snow will continue inland, but southeastern Connecticut will see a period of rain mixing in with the snow. This will cut down on totals, but also make the snow much heavier/wetter, and thus difficult to remove. Snow continues into Sunday morning as it gradually weakens. Slick travel is likely to begin the day Sunday, too. The strongest gusts will top out around 30 mph or so. Winds will coincide with the period of heavier snow, peaking through late Saturday evening and eventually relaxing midday Sunday. Isolated power outages are possible but we do not expect widespread issues."

"Given the storm trends, we’re expecting 6-10″ along and northwest of I-84," Dixon and Gilardi said. "A few towns in Litchfield county may report totals slightly over the 10″ mark. Towns throughout the Quiet Corner will fall in the 6-10″ range, too. Forecast totals of 3-6″ are expected in the Greater Hartford Area, as well as for inland sections of New Haven, Middlesex, and New London Counties. Mixing along the shoreline and in southeastern Connecticut will keep totals lower, ending in the 1-3″ range." (Read/watch more at WFSB 3 TV).

Expect up to 1 1/2 ft of inundation above ground level in low lying, vulnerable areas.
