WEATHER UPDATE: Snow's 'Big Impact' on Tuesday Evening Commute in New Canaan

By Brian McCready (Patch Staff)

You might want to sneak out of work a little early today, probably by 4 p.m. just to be on the safe side.

And while you’re at it, you might want to call out in advance for Thursday, where more than six inches of snow is possible late Wednesday into Thursday afternoon.

Yes, more snow is forecast for tonight’s commute home from work, as snow is expected to begin falling around 4 p.m. and be relatively heavy in intensity, before it changes to ice late Tuesday, and then some light rain showers on Wednesday.

The National Weather Service has issued a Winter Weather Advisory for the entire state of Connecticut from 3 p.m. today until 10 a.m. Wednesday.

A total of 2 to 4 inches are expected, but what has prominent Connecticut meteorologists concerned is the icing that is going to occur, and could make Wednesday morning’s commute “treacherous,” writes WFSB 3 TV Meteorologist Scott Haney.

And the ride home from work tonight won’t be a walk in the park, either.

NBC Connecticut Meteorologist Bob Maxon predicts snow begins tonight after 4 p.m. and it will have a “big impact on the evening commute.”

WTNH News 8 Meteorologist Gil Simmons writes that it will be a “very rough commute” home tonight, and “snow and dangerous freezing rain and sleet” will impact Wednesday morning’s commute.

Simmons predicts snow could begin falling by 4 p.m. in Western Connecticut and by 6 p.m. in Eastern Connecticut.

As for Thursday’s potential snowstorm?

“I may have to go into hiding if current guidance verifies Thursday. Models aggressive with moisture plume & cold air Thursday morning,” Simmons wrote on Facebook.

NBC Connecticut Meteorologist Brad Field wrote on Facebook “thinking late Wednesday night/Thursday snow could be substantial...still a bit too early to be more certain…”
