WEATHER UPDATE: More Snow for Thursday Morning's Commute, Sub-Zero Wind Chills Forecast for Greenwich

By Brian McCready and Barbara Heins (Patch Staff)

It appears Mother Nature is in the business of nickel-and-diming us when it comes to snow now.

The National Weather Service has issued a Hazardous Weather Outlook for 1 to 2 inches of snow to fall late tonight and smack dab in the middle of Thursday morning’s commute to work.

WTNH News 8’s Meteorologist Gil Simmons writes on his Facebook page, “quiet weather today but changes tonight/tomorrow. Snow squalls likely Thursday morning, plan on a slow commute.”

And in reality the one or two new inches of snow isn’t really the greatest concern. As part of its Hazardous Weather Outlook, the National Weather Service states wind chill values will fall as low as 20 to 25 below zero Thursday night through Friday morning.

Wind chills will remain below zero throughout the day on Friday and Friday night.

And the weekend is still days away but right now we could be looking at a nasty mix of snow, ice and then plain rain, which could compromise roofs that are already under a lot of snow, writes NBC Connecticut Meteorologist Darren Sweeney, on Facebook.

“Concerns for the weekend! Snow, to ice, to RAIN??

It’s only midweek, but I am looking toward the weekend.

First and foremost, many will ask, with the impending (new) blast of frigid air, how can you be talking about RAIN? for the weekend?

First off: Snow showers will usher in another absolutely frigid air Thursday night into Friday.

Saturday: Increasing clouds with snow developing on Saturday night.

The problem? High pressure will be in a position off of the coast to NOT lock in cold air. In fact, a storm center may even go to our west and pull in some warmer air.

This is not a good thing. we already have problems with “roof loading”.. that’s a buildup of snow on our roofs (those living in eastern CT you are about 20 inches ahead of everyone else).

Adding LIQUID to this, means we could be dealing with roofs being compromised. Also, all drains are clogged, you get the picture .

While it’s hard to fathom that this cold pattern will support a change to rain, it’s been pretty consistent in the models.

I wanted to give a heads up, as today is a good day to get out there (if you can) OR call someone who can help. I know I will be out on my roof because it’s getting scary deep.”
