Long Island weather: Wintry mix overnight turns to rain for Presidents Day

Those taking Presidents Day week off from school or work will be lucky enough to skip some potentially messy commutes. And let's not even think about those lucky enough to be on Caribbean vacations this week. 

A wintry mix of sleet, rain and in some places snow is predicted to affect Long Island on four days this week, according to the National Weather Service.  

The first shot of that wintry mix already moved into Long Island on Sunday night and will last through Monday morning, forecasters said.

"It is going to be a messy morning commute, although it is a holiday," said meteorologist Nelson Vaz.

Accumulation of 1 to 1.5 inches of snow was predicted for some parts of Long Island, with the higher amounts on the North Shore.

But temperatures were slowly rising so the precipitation should change over to mostly light rain and drizzle for Presidents Day. It's expected to clear by early Monday afternoon. But black ice is possible Monday evening  after temperature hovers around the upper 30s during the day, then falls to the 20s later.

Tuesday will be sunny, yet chilly, with a high of 35 degrees, slightly below the average of 41 for this time of year, said Tim Morrin, a weather service meteorologist in Upton.

But a wintry mix could hit again Wednesday and turn into rain by Thursday morning, Vaz said. It's too soon to say how much could accumulate, he said. 

The rain is expected to end Thursday, but clouds will persist, and the temperature is expected to reach 43. Friday’s forecast calls for sun and a high of 43, Morrin said.
