Even Mother Nature is looking forward to summer this Memorial Day weekend, with unseasonably high temperatures expected for the holiday, according to the National Weather Service.

Sunday's highs were in the high 70s in many parts of the Island. Lows Sunday night will be in the mid-50s, said Lauren Nash, meteorologist with the service's Upton bureau.

The weather service clocked a high temperature of 77 degrees in Islip. The record high for this day was in 1991 when it was 92 degrees.

On Monday, Memorial Day, get ready for temperatures that could reach 80 degrees -- about 10 degrees higher than the average for this time of year, Nash said.

Monday night's lows will sink into a comfortable 60 degrees.

Tuesday's highs will be in the upper 70s, with a 30 percent chance of rain in the afternoon. Lows on Tuesday will be in the mid-50s.

The chance of rain continues through Wednesday afternoon, Nash said.

Highs from Wednesday through the end of the week will be in the low 70s, with lows in the mid-50s.

A chance of precipitation returns on Friday, with another slight chance of showers.

That rain won't be significant, Nash said. "It's not a widespread, long-duration event," she said.
