Five things you need to know about the snow

February 27, 2019

A few inches of snow could make the the Wednesday evening and Thursday morning commute slippery.

The National Weather Service has issued a Winter Weather Advisory for most of Connecticut from 3 p.m. Wednesday to 6 a.m. Thursday.

“Plan on slippery road conditions. The hazardous conditions could impact the evening commute,” the NWS says. “A Winter Weather Advisory for snow means periods of snow willcause primarily travel difficulties. Expect snow covered roads and limited visibilities, and use caution while driving.”

1. How much snow is forecast?

Three to 4 inches for interior portions of southern Connecticut.

Two to 3 inches is forecast for the shoreline.

In northwest Connecticut, most areas will see between 4 to 6 inches.

The New York City area should see about an inch.

2. When will the snow begin and end?

Snow will arrive in western Connecticut “between this afternoon and early this evening,” the NWS says.

The steadiest snow will fall tonight, but should end by sunrise on Thursday.

The NWS’s hourly forecast says there a chance of snow between noon and 2 p.m. and from 5 to 7 p.m.

Snow is likely between 8 p.m. and 2 a.m.

NBC Connecticut has snow breaking out in southwest Connecticut at 3 p.m. and 5 p.m. in northwest Connecticut.

Snow will cover all of the state from 11 p.m. to 2 a.m.

3. The evening and AM commutes

Wednesday’s late afternoon/evening commute could be affected most if snow arrives earlier.

The heaviest snow will, however, be falling after the Wednesday evening commute.

Thursday’s morning drive will likely be slick with a few inches of snow on the ground.

Delayed school openings are also likely Thursday, especially in inland areas of the state.

4. How much snow have we had this winter?

At Sikorsky Memorial Airport in Stratford, 10. 8 inches of snow has fallen. That’s about half of the average 21.3 inches for this time of year.

About half of the 10.8 inches of snow that fell at Sikorsky was from a Nov. 15 snowstorm that made a disaster during that day’s evening commute.

That storm dumped up to 11 inches in New Fairfield more than a month before winter officially began.

In 2011, we saw the record highest snowfall to date on Feb. 28 when 59.4 inches of snow had already fallen at Sikorsky.

The lowest snowfall total on record for Sikorsky is 3.3 inches in 1980.

Last winter, Sikorsky airport had 36.9 inches of snow - 14.4 inches above average.

Three nor’easters - two with mostly snow - pumped up seasonal snowfall totals.

The biggest snowfall last winter was on Wednesday, March 7 where areas like Newtown saw more than two feet.
