After a showery Monday, Tuesday introduces a stretch of sunny daytime skies right through the end of the workweek, forecasters said.

However, just as Long Islanders are settling in to the notion that autumn truly has arrived after a warm start to the month, a cooler than normal spell appears to be on the horizon.

"We do have a few chances of frost" in some spots this week, said News 12 Long Island meteorologist Rich Hoffman.

Tuesday is expected to warm up to nearly 60 degrees, cooling down to an overnight low in the mid-40s, the National Weather Service says. The normal high for the day at Long Island MacArthur Airport in Ronkonkoma is 63 degrees, and the normal low, 45.

As of just before noon, MacArthur was reporting a temperature of 53 degrees and winds from the northeast of 13 mph, down from earlier morning speeds in the 20 mph range and gusts above 30 mph. The weather service issued a small craft advisory for ocean waters off southeastern Suffolk County until 6 p.m.

"Temperatures are dropping, and we’ve got some strong, gusty winds out there," Hoffman said Tuesday morning.

Wednesday is forecast to see temperatures rise to the low 60s, then cool off to the low 40s overnight.

Thursday, warming up to 50 degrees or so, offers a taste of late November daytime temperatures, as overnight lows of about 40 degrees are expected.

Suffolk County around the pine barrens could see temperatures of 35 to 40 degrees with patchy frost, Hoffman said. 

Then, Friday rebounds somewhat to the upper 50s and showers enter the picture overnight.

Saturday looks to reach 60 degrees or so, with Sunday warming up only to the low 50s, and dipping to a low of 40, the weather service said. That’s when the pine barrens area could fall further to the lower 30s, Hoffman said.

We won’t want to entertain hopes for a return to balmy conditions anytime soon, as the Climate Prediction Center says there’s an 80 to 90 percent probability for temperatures in the Northeastern United States, Long Island included, to average out at below normal for Sunday through next Thursday.
