Long Islanders were facing another stretch of precipitation Saturday, with skies most likely drying out for Sunday, as cooler than normal temperatures persist through the weekend and into early next week, forecasters say.
“April has basically become an extension of a very cold and snowy March,” said Tim Morrin, National Weather Service meteorologist in Upton. “These weather patterns, when they get into place, they don’t flip on a dime.”
Saturday was looking at chances of precipitation starting in the early hours as rain showers, with an hour or two of changeover to “light, wet snow” around daybreak with no expected accumulation, Morrin said. That’s based on the late Friday afternoon forecast.
By midmorning or so, precipitation will be departing, he said, with skies partially clearing for the afternoon.
Temperatures were expected to head up to the high 40s, with 55 degrees the normal high for the day at Long Island MacArthur Airport.
That’s as a “colder than average weather pattern will continue this weekend, and latest indications are keeping the pattern in place into next week,” the weather service said in its regional summary.
The reason, said Morrin: “the jet stream is in position to allow cold air in Canada to come down and funnel into the Atlantic and Southern New England,” a phenomenon that’s atypical for early spring.
The forecast for Sunday was for mostly sunny skies, with a storm system looking to stay far enough offshore that only eastern areas of Long Island were susceptible to being slightly brushed by a hint of snow, the weather service said.
However, forecasters were watching the storm’s track, Morrin said, and a shift to the north or west could mean the introduction of slightly more snow. That’s as temperatures again rise to the upper 40s.
As for early next week, look for “mostly sunny and chilly” conditions, the weather service said.
The weather service’s next major forecast update comes about 4 a.m. Saturday.
