Sunday’s clouds and unseasonably warm temperatures — more typical of late March on Long Island than mid-December — are expected to be replaced in time for the Monday morning commute by mostly clear skies and a return of chilly air, according to the National Weather Service.

Late Sunday night, forecasters also downplayed earlier warnings about treacherous black ice on Long Island roadways after dark but underscored the need for drivers to remain cautious in areas where water is known to pool.

The high was 56 degrees Sunday at Islip — approaching the record of 59 degrees set in 1984. But temperatures were expected to drop into the 20s overnight and stay there for much of Monday, said Brian Ciemnecki, a meteorologist with the National Weather Service in Upton.

The high Monday will hover somewhere around 30 degrees, but the good news is that the return of freezing temperatures won’t bring brief whiteout conditions like those that hit Long Island Thursday and accumulating snow that fell Saturday morning.

“Precipitation is over,” Ciemnecki said. “It’s going to be dry” Monday and Tuesday.

Monday will be mostly sunny with gusts of up to 11 mph and a wind chill between 10 and 20 degrees, according to the National Weather Service.

By Tuesday, temperatures are expected to reach the upper 30s, he said.

Expect a mix of sun and clouds on Wednesday with highs near 43 and lows near 32. On Thursday, clouds will increase, and a storm system may bring rain in the late afternoon that will continue into the overnight hours with highs in the mid-40s and lows in high 30s.

Friday brings more cool days and chilly nights with mid-40 highs and lows in the low- to mid-30s. Forecasters predict much of the same for Saturday and Christmas.
