Enjoy it while it lasts.
Sunny skies and high temperatures are expected to be in the upper 40s -- about 5 degrees above normal -- Saturday on Long Island.
But the balmy weather of this weekend will be fleeting. After Sunday, temperatures are predicted to plummet again, about 10 to 15 degrees below average in some locations, causing freezing and the possibility of some light snow.
Monday's high is expected to be in the low 30s.
"And that will be the warmest day of the workweek," said Lauren Nash, a meteorologist with the National Weather Service in Upton.
The average temperature recorded at Islip around this time of year is 40 degrees.
While the melting snow on the ground isn't expected to create any flooding this weekend, Nash says that anything that's left over after Sunday will result in frozen ice patches all next week.
For example, Thursday night's low temperature is expected to be at 11 degrees, Nash said.
The take-home message: Don't put the hats and gloves away just yet.
