For the first time this season the National Weather Service (NWS) has issued a weather advisory. Rain and wet snow are expected within the next 24 hours.

It will not be long lasting, however, as the advisory is suggesting that just up to 1 inch of snow is possible, “along with from around a trace to up to a tenth of an inch of ice,” according to the weather service.

While it feels chilly this morning — a nice change, for those who enjoy winter, compared to the relatively balmy temperatures of Christmas morning just a few days ago — the National Weather Service is advising of some changes expected within the next 24 hours. While an advancing weather pattern may finally bring some snow into the area, warm temperatures right behind tonight and tomorrow morning’s precipitation means most of what falls will melt quickly.

A Winter Weather Advisory was issued at 3:50 am Monday, December 28, covering portions of southern Connecticut. Within minutes of that bulletin, the advisory area and timing were both extended, however.

A Winter Weather Advisory now covers all of Fairfield, New Haven and Middlesex counties, along with northern New London Country. The advisory also includes the New York counties of Orange, Putnam, Westchester, and Rockland, and Bergen and Passaic counties in New Jersey.

A wintry mix is expected to develop across the tri-state area tonight, moving from west to east. There will be a prolonged period of sleet and light freezing rain across interior portions of the affected area into Tuesday morning, according to the NWS. The biggest expected impacts would be slippery roadways and sideways, “with the main threat being to elevated surfaces and higher elevations in the advisory area,” the advisory notes.

The advisory is in effect until 11 am Tuesday, December 29. Travel difficulties for late Monday evening into Tuesday morning can be expected due to “periods of snow...sleet...or freezing rain,” the advisory continued. “Be prepared for slippery roads and limited visibilities...and use caution while driving.”

A look at NWS’s detailed forecast for Newtown appears that residents can expect some form of precipitation this evening. While there is “a chance of show and sleet between 9 pm and midnight, then freezing rain and sleet” after midnight (with a low around 28 degrees), the chance of precipitation increases to 100% after midnight and into Tuesday morning.

The overnight accumulation of ice is projected to be little or none, and the snow accumulation is expected to be “less than one inch possible.” Tuesday morning may be messy, but accumulation will again be extremely low, according to NWS as of mid-Monday morning. Tuesday will dawn with freezing rain and sleet before 8 am, rain and sleet between 8 and 9, and then changing to rain after 9, when temperatures could reach up to 41 degrees.

Chance of precipitation is 100 percent for Tuesday morning, but new sleet accumulation of less than half an inch is being predicted by the weather service.

Tuesday’s weather will only take any traces of winter away quickly, with clouds for the overnight followed by another chance of rain on Wednesday. A 70 percent chance of rain for Wednesday’s overnight, combined with temperatures in the high 30s, means cautions should be taken while driving or even walking outdoors.

So while it may look like winter for a short time during the next 24 hours, it doesn’t sound like the wintry scene will stick around for too long.
