Clouds threatening Long Island with storms and hail Tuesday night have cleared off after a day in which temperatures hit 90, the National Weather Service said.

Meteorologists had issued a hazardous weather outlook, forecasting potentially strong to severe thunderstorms that could bring small hail and gusty winds.

But those clouds have largely dissipated, meteorologist Mike Layer said early Tuesday evening from the service's Upton office: "As they came east, they kind of weakened. We may end up getting through the evening dry."

An air quality alert remains in effect for Nassau and Suffolk counties until 11 p.m. Tuesday, the service said.

State environmental officials, which issued an air quality health advisory, predict outdoor air pollution levels will be elevated during that time.

Officials recommend residents consider limiting strenuous physical activity outside. Young children and those with pre-existing health conditions, such as asthma or heart disease, are at greatest risk, officials said.

A day after temperatures reached a high of 92 degrees at Long Island MacArthur Airport and storms hit parts of the Island, the thermometer Tuesday hit 90 at Islip, the service said. That fell short of the record high for the date -- 92 in 2003, Layer said.

There's also a moderate risk of rip currents at ocean beaches, the weather service said.

A stormy pattern may continue the rest of the week.

"Periodic showers and thunderstorms Wednesday through the weekend could result in localized flooding . . . especially Thursday through Friday, when severe weather will be possible as well," the weather service said in a hazardous weather outlook.

Hempstead Supervisor Kate Murray is urging residents of her town to beat the heat: She announced Monday that through Wednesday the town is extending hours at its eight pools and seven beaches, and 15 cooling centers will be open from 9 a.m. to 8 p.m.

Tuesday night's temperatures may dip into the upper 60s, while Wednesday should be a few degrees cooler. Layer said temperatures will hit the upper 80s.
