Another December day, another record-setting high temperature on Long Island.

A high of 57 degrees, recorded just after midnight at Long Island MacArthur Airport, broke the 2006 record high of 54, said Carlie Buccola, a meteorologist with the National Weather Service’s Upton office. Temperatures later in the day are expected to be in the mid 50s.

This month so far, through Friday, the temperature is registering 12.4 degrees above normal at 48.9 degrees, according to the weather service.

Sunday’s high is also potentially record-setting, Buccola said. Service data predicts a high of 65 degrees, which is 7 degrees warmer than 2011’s record of 58 degrees.

Both days will be cloudy, with a band of showers coming through. The rain should start Saturday evening and continue into Sunday morning.

Despite the warm weather, it may not be a good time to take out the boat. A small craft advisory is in effect along the South Shore. Rough seas and high winds are expected through 6 a.m. Sunday.
