It’s been another day of abundant sunshine and unseasonably warm temperatures across Long Island, the National Weather Service said Monday.

Daily highs reached the mid 70s: By 11 a.m. the temperature had already hit 70 degrees at Long Island MacArthur Airport and two hours later it was 75 degrees. Temps ticked up to 74 by 3 p.m.

Overall, temperatures Monday are about 15 degrees above normal for this time of year, the service’s Upton office said.

But it was nowhere near the 2002 record of 89 degrees.

The mostly dry air and gusty conditions that are expected to dominate the region the next few days could present a problem.

Monday, the service put out a statement at 3:16 p.m. for the entire tri-state area, saying there was a “fire weather watch” for Tuesday afternoon and evening.

Such a watch means “critical fire weather conditions are forecast to occur,” the service said, saying Tuesday’s dry weather will make for “conditions favorable for rapid brush fire spread.”

Winds are predicted to be between 10 and 20 mph Tuesday with gusts of 25 mph.

News 12 Long Island meteorologist Rich Hoffman said much of the week will be dry and warm, with some chance of showers for Tuesday and again on Saturday.

Hoffman said that as in the summer months, when sea breezes kick up in the afternoon, a drop in shoreline temps are likely to follow on Monday.

North winds open at about 6 mph and lighten during the afternoon hours, the weather service said.

The service also warned of very dry conditions Monday afternoon that elevate the risk for brush fires. The North Shore of both Nassau and Suffolk counties are susceptible because of dry ground conditions, low relative humidity levels and relatively light winds.

Hoffman said there are “a few chances of wet weather” during the next seven days, but it works out to be “a lot more dry time” with above-normal temperatures lingering into the weekend.

Clouds increase Monday night and some showers could appear overnight toward Tuesday morning, Hoffman said.

Morning clouds and a chance of showers give way to a mix of sun and clouds during the daytime Tuesday, he said.

Daily highs in the mid 60s are expected, with winds shifting from the west to the north at 10 to 20 mph.
