Long Island weather: Heavy rain, gusty winds and flooding Friday night into Saturday 

Heavy rain, strong winds and possible flooding are in store for Long Island on Friday night into Saturday, according to the National Weather Service.

"Strong low pressure will bring a wintry mix to the interior, and heavy rain, strong winds, and moderate coastal flooding [Friday night] into Saturday morning," the weather service said in a storm advisory Friday evening.

The weather service issued a coastal flood warning of 1 ½ to 2 ½ feet of water above ground in the most vulnerable coastal communities across Long Island.

About 1 to 1½ inches of rain is expected on Long Island, possibly up to 2 inches in some spots, and there could be flooding along the "most vulnerable coastal communities" during Saturday morning's high tide. The extent of flooding has to do with how the winds shift during the storm, forecasters said.

Long Island is not expected to see any accumulating snow, but some communities could see snow flurries as part of a wintry mix. 

Easterly winds of between 20 and 30 mph, with gusts to up 50 mph, are forecast for Long Island and southeastern Connecticut from midnight Friday to 6 a.m. Saturday. Isolated downed
tree branches and power lines are possible, the weather service said.

Any downpours should clear by early Saturday afternoon, when the daytime high will hit the mid-40s, setting the stage for the next several days. 

At night, thermometers will hover around freezing.

Sunday should be mostly sunny, with highs in the mid-40s.

Sky-clearing high pressure then arrives from the west, starting Monday off with sunshine.

There is a chance of showers Monday night into Tuesday morning and once again, the coast may only see rain, but a mix of rain and snow may fall inland.
