Long Island weather: Sunny weekend, with temps nearing 70

Sunny days and seasonal temperatures are here this weekend on Long Island, signifying an upward trend after lower-than-normal temperatures so far this month.

The skies will stay clear Saturday, Sunday and Monday, with the chance of precipitation returning after midnight Monday into Tuesday, said John Murray, a meteorologist with the National Weather Service’s Upton bureau.

“It’s going to be a pretty quiet weekend with high pressure in control; we’ve got clear conditions we’re expecting to last through this weekend due to that high pressure,” Murray said.

An elevated wildfire risk notice was issued by the service just after 4 a.m. Saturday for parts of Nassau and Suffolk counties. Dry conditions due to a drop in relative humidity combined with northerly winds, with gusts around 25 mph, will create “an elevated risk for fire growth and spread,” the special statement said.

For Saturday, high temperatures will reach the upper 50s to near 60, Murray said, before they dip down into the lower 40s, with eastern Suffolk reaching the mid-30s.

On Sunday, Long Island will have sunny conditions once again, Murray said, with temperatures rising a bit higher to the mid-60s, and upper 60s for western Suffolk and Nassau.

Temperatures will cool down Sunday night to the mid- to upper 40s and warm back up again on a sunshine-filled Monday, with highs in the mid- to upper 60s and around 70 in northwestern Suffolk and Nassau.

Clouds are expected to increase Monday night and will bring a chance of showers after midnight, but Murray doesn’t expect “anything significant” in terms of rainfall amounts.

Spring kicked off this year with several record-high temperatures in Islip, at 71 degrees on March 23, 60 degrees on March 25, and 65 degrees on March 31, Murray said. But the average temperature so far this month, taken from readings at Long Island MacArthur Airport, has been 44.6 degrees, which is about 2.1 degrees below normal, Murray said.

Precipitation levels have also been below normal, clocking in at 1.61 inches, about 0.66 inches lower than normal.

“April is one of those months that makes it unique because you have such a wide range of conditions from start to end,” Murray said.

Long Islanders saw snow twice this month in the first week, with flakes falling on April 3 and 5, Murray said.
