Dry, sunny conditions settle in for the next several days, the National Weather Service said Thursday.
The service's Upton office is calling for daily highs primarily in the low to mid 70s through the weekend, with light variable winds.
On Thursday, highs in the low 70s across Nassau and Suffolk counties are expected, with cooling sea breezes likely in the late morning and afternoon hours, the service said.
Winds from the east at 6-9 mph are likely to shift the south in the afternoon.
News 12 Long Island meteorologist Rich Hoffman said temperatures for the next seven days are likely to be above normal, but he's keeping an eye on a marine layer developing over Long Island waters.
This layer of warm air lingering over chilly ocean waters could bring in some cooler conditions, he said.
Low morning clouds with some drizzle and light fog are possible if the marine layer is heavy, but those conditions should dissolve by midday.
"If the marine layer holds into the afternoon the forecast will have to include more clouds and cooler temperatures for the weekend," Hoffman said.
Otherwise, from Thursday through Sunday daily high temperatures in the mid to upper 70s are likely, with clear, sunny skies and light variable winds.
Fog and light drizzle could develop in the overnight hours -- Thursday night into Friday morning and Friday night into Saturday morning.
Overnight lows through Sunday range from the mid to upper 50s.
