Better keep that heavier coat handy for Tuesday morning.

Temperatures are expected to be in the high 40s, possibly warming up to the low 50s in the afternoon, said Tim Morrin, National Weather Service meteorologist based in Upton. This on a day when the normal high in Islip is 60 degrees, he said.

Monday, too, was on the chilly side with Islip recording a temperature of 43 degrees about 8 a.m., rising to the low 50s by late morning.

Tuesday is expected to be "a raw, breezy day . . . with winds off the ocean," he said, this as a storm in the western Atlantic is expected to "graze" the East End of Long Island late Monday night, bringing "occasional light rain or drizzle" into the morning.

As for the rest of the week? Look for temperatures in the 60s, he said.
