As a prelude to the long Fourth of July weekend, Friday is looking to bring some much-needed rain, at times potentially heavy in some spots, forecasters said.

Then, enter three days of sunny skies, for the most part, with nary a drop of rain in sight, at least as of Thursday’s forecast.

Any showers before Friday evening are expected to be “light and scattered,” with the best chances for heavier showers or thunderstorms in the late afternoon and evening, said Bill Korbel, News 12 Long Island meteorologist.

In fact, the National Weather Service Thursday afternoon issued a hazardous weather outlook for Nassau County, warning of a few storms Friday afternoon and evening that could be severe, bringing “damaging wind gusts.”

Given the variability of where downpours might occur, amounts can’t really be called, Korbel said, but “there will hopefully be at least some rain everywhere on LI and enough to water the lawns.”

Long Island MacArthur Airport is slightly more than three inches below normal for the month, with the Island remaining in the moderate drought category, according to the U.S. Drought Monitor’s Thursday update.

“The weather looks wonderful for all three weekend days, with sunshine . . . warm temperatures and reasonably comfortable humidity levels,” Korbel said.

Highs of around 80 are expected, cooler at the shore, with sunny or mostly sunny skies, the weather service said.

We’re looking at “great sleeping weather, great barbecue weather, great fireworks weather,” said Bill Goodman, weather service meteorologist based in Upton.

From west to east, ocean beach temperatures on Thursday ranged from close to 70 to the low 60s, he said. The Great South Bay was registering 77 degrees.

Overall, conditions did not appear to be in place to favor high rip currents in the coming days, but that needs to be monitored each day, he said.

Monday night and the Jones Beach fireworks show, starting at 9:30 p.m., is a ways off, but the forecast as of Thursday indicated fine weather for that part of the night, he said. There’s a slight chance of showers — 20 percent — for the overnight into Tuesday time frame.
