Big Changes Ahead In The Long Island Forecast

It was a chilly 46 degrees at sunrise on Long Island Monday before the temperature climbed to 72 degrees at MacArthur Airport in the afternoon. But if you are wishing for one more taste of summer, you will like the upcoming forecast.

A high-pressure system will slide south of the area on Wednesday, resulting a gradual warming trend for area, the National Weather Service says. Thursday's high will be near 80 degrees.

Temperatures will remain about 10 degrees above normal for this time of year on Friday. Rain, however, will threaten Columbus Day weekend.

"Tropical moisture may surge northward ahead of the approaching cold front, leading to the potential for heavy rainfall into next week," the NWS says.
