The workweek starts out with another above-average temperature day, with Long Island MacArthur Airport hitting 80 degrees at about 10 a.m. Monday, forecasters said.

That's the second time the airport hit 80 degrees this year, the first being Sunday at 1:48 p.m., said Joe Pollina, National Weather Service meteorologist based in Upton.

Monday, though, is giving way to a week of mostly normal temperatures in the mid to upper 60s, he said, as well as unsettled skies bringing "hit or miss" rain showers and culminating with the possibility of "a couple of inches of rain" Friday into Saturday.

As a cold front moves through, there's a 40 percent chance for showers after midnight, leading into a mostly cloudy, rain-free day Tuesday, the weather service said. There's a slight chance of showers after midnight Tuesday and through the day Wednesday and into Thursday, the service said.

None of those days is expected to be a "wipeout," Pollina said, but then comes Friday.

"The potential for heavy rain exists" Friday into Saturday, the weather service said. "While it is too early to pinpoint exact amounts . . . a couple of inches are possible."
