Temperatures on Saturday will stay in the range of the low 50s on the Twin Forks to the mid-50s in Nassau County, the service said. Across Long Island on Saturday night, temperatures will fall to the mid-40s. By comparison, the service says the normal high for this date in Islip is 70 degrees; the low is 53 degrees.
Saturday will continue to be breezy, with northwesterly winds between 20 and 25 mph. The National Weather Service issued a wind advisory starting at 4 p.m. Saturday afternoon, and lasting until midnight. Joey Picca, a meteorologist for the service, cited winds between 20 and 30 mph, with gusts up to 50 mph.
On Saturday night winds will slow to between 15 and 20 mph.
Sunday, said Pollino, will be "dry and partly sunny" with highs in the 60s. Overnight, he added, "it will still be pretty chilly," averaging in the 40s across Long Island and the upper 30s in the pine barrens.
