Storm pushes out Sunday's record heat

While Sunday's temperatures across Long Island may have seemed like a reprieve from the heat wave of only a week ago, they could still be called "record-breaking."

The National Weather Service in Upton said that Sunday's afternoon high in Islip -- 89 degrees -- bested the previous July 1 high mark for the region, 87 degrees, set in 2001.

It wasn't as hot as the 97 degrees logged at LaGuardia Airport, tying its 1964 record for the same date. But since Islip's daily records have been kept only since the 1980s, officials said a relatively mild reading can often set a new best.

"We do get a lot of records like that in Islip," said Tim Morrin, an observation program leader at the weather service's Upton office.

The heat was ushered out late Sunday by a fast-moving thunderstorm with hail the size of quarters.

No serious damage was reported as result of the storm, which caused several small pockets of Long Island Power Authority customers -- never more than 300 -- to be without power briefly in the early evening.

Arrivals and departures at LaGuardia and Kennedy airports were also delayed as the thunder, lightning and hail moved through.

Parts of eastern Nassau County and most of Suffolk were under severe thunderstorm warnings that expired before 7 p.m. Although wind gusts of up to 60 mph were predicted, "winds haven't really been an issue," Morrin said. "Really, it's predominantly been the hail reports."

For the upcoming week, slightly cooler temperatures are predicted.

Monday's highs will reach into the mid- to upper 80s, with lows in the mid-60s, meteorologist Joe Pollina said Sunday. A 20 percent chance of precipitation will linger into Monday night.

Tuesday's highs will be close to 85 degrees, with lows of about 70, forecasters said.

On Wednesday, the Fourth of July, the predicted high temperature is 87 degrees, with the chance of precipitation increasing to about 40 percent.

The rest of the week appears dry, with a high of 84 and low of 70 on a mostly sunny Thursday, and a high of 86 and low of 71 on a sunny Friday.
