Look for a pleasant day Easter Sunday for getting out and about to family festivities and parades, with sunny skies predicted for the start of the day and no rain in the forecast until late at night.
“It’ll be seasonable,” said Nelson Vaz, a meteorologist with the National Weather Service at Upton. “It’ll be pretty much normal for this time of year with highs in the low 50s.”
News 12 Long Island meteorologist, Norm Dvoskin, said highs will be 54 in Hicksville, 51 in Medford and Smithtown, and 47 on the East End in East Hampton.
A low-pressure system approaches Sunday evening, bringing with it an 80 percent chance of rain that is expected to last into the Monday morning commute.
“The low pressure system increases the chances for rain this evening after midnight to 2 a.m.,” Vaz said. The low will be in the lower 40s.
On Monday, “There’ll be a rainy start to the morning, but it won’t be a heavy, heavy rain,” Vaz said. “The rain should lighten up in the afternoon — there may be a quarter of an inch to an inch [of accumulation].”
Highs will be in the mid 50s and lows at night are predicted in the lower 40s, with gusty winds blowing through into Tuesday.
“As the low-pressure system departs the area, late Monday winds are going to be picking up and increasing and getting quite gusty late Monday — about 40 miles per hour into the evening,” Vaz said. “They’ll be gusting westerly winds.”
Winds gusting from 30 to 40 mph continue into Tuesday, when highs will be in the low to mid 50s and there will be a mix of sun and clouds. At night, the winds start to diminish, but it will turn chilly at night with lows in the 30s.
More dry conditions are ahead for Wednesday, when there will be “a good amount of sun,” Vaz said. Highs will be in the lower 50s.
“At night a high-pressure system will be moving east of the area and warmer air will be coming in,” Vaz said. Lows at night will be in the 40s.
“Thursday is the next low-pressure system and ahead of that southerly winds warm the area,” Vaz said. It will be rather mild in the lower 60s with the approaching frontal system. There’ll be increasing clouds and a chance of showers during the day, but it doesn’t look like a washout. There’ll be spotty showers.”
On Thursday night, Vaz said, the frontal system will get closer and rain will likely be at night. Temperatures will remain mild in the lower 50s.
“For Friday, it depends how quickly the system moves through and there could still be rain-shower potential,” Vaz said. Lows will be in the lower 60s, then temperatures drop into the 40s at night.
