Long Islanders have just a few hours to enjoy the sunny skies Saturday before clouds start to roll in, bringing with them rain showers and thunderstorms.

The fog that built up overnight was quickly burned off this morning, clearing the way for the sun to shine, said Jay Engle, a meteorologist with the National Weather Service’s Upton bureau.

“Today we’ll have partly and mostly sunny conditions this morning with a chance of showers later in the day,” Engle said, noting the rain would start after 5 p.m.

Matt Hammer, a meteorologist with News 12 Long Island, credits the stormy weather to a cold front from the west sweeping across the Island. The system is expected to bring “just a few quick hit-or-miss pop up showers” with “brief, heavy rain and gusty winds,” Hammer said.

Some areas on the Island could expect anywhere from a quarter-inch to a half-inch of rain, but those amounts could vary significantly from backyard to backyard because of the scattered thunderstorms, Engle said.

“Because thundershowers are more variable, depending on where you are, you could get a lot more or a lot less,” Engle said.

High temperatures Saturday will be in the low 70s, with Saturday night’s mercury hitting in the upper 40s, Engle said, temperatures that are around normal for this time of year.

The rain is expected to taper off around midnight. On Sunday, increasing clouds will cover the area and bring another chance of showers around 3 p.m., but “otherwise, most of the day is dry,” Engle said.

Highs for Sunday will be in the mid- to low 60s, a little below average for this time of year. Winds are expected to reach 30 to 40 mph out of the northwest, Hammer said, “that will make it feel like we’re in the low 50s.” The evening will be a bit cooler, mostly cloudy with a low in the 40s.
