Thursday’s sunshine should last a couple more days, but Long Island could see some rain Sunday and perhaps some snow mixed in Sunday night with the official start of winter less than two weeks away.

The temperature rose to 54 degrees just at 2:12 p.m. Thursday in Islip but was expected to drop to about 33 degrees Thursday night.

The National Weather Service said Thursday evening that Friday will be sunny with a high temperature near 45 degrees as a north wind blows at 8 mph to 10 mph.

Friday night will be partly cloudy with the low temperature possibly falling below the freezing mark to 30 degrees, which would be one degree below the normal low for the date, forecasters said.

Saturday should be mostly sunny with a high near 43 degrees but Sunday brings a 50% chance of rain after 1 p.m., and a high temperature near 44 degrees.

Sunday night could look a little wintry. Rain is likely before 1 a.m., then a chance of rain and snow. The low temperature will drop to around 31 degrees, according to the weather service. 

The start of the new workweek Monday will bring partly sunny skies and Tuesday will be sunny, the weather service said. Both Monday and Tuesday are expected to have high temperatures of only about 41 degrees.
