Tuesday's overnight into Wednesday could be a stormy one, forecasters said, with showers likely in the morning as well.

The National Weather Service says there is 100% chance of overnight showers, with the possibility of thunderstorms after 10 p.m., heavy rain producing between 1 to 2 inches and wind gusts up to 41 mph.

"The timing of the heaviest showers is likely to be around midnight through early Wednesday morning, with the showers largely ending by midday," the weather service said. "Minor urban and poor drainage flooding is the main threat as conditions have been dry and flash flood guidance is quite high."

For Western Suffolk, the weather service issued a wind advisory that begins at midnight and ends at 6 a.m. on Wednesday. A wind advisory for eastern Suffolk runs from midnight through 8 a.m.

"Gusty winds could blow around unsecured objects. Tree limbs could be blown down and a few power outages may result," the weather service said.

Wednesday morning could bring a 60% chance of more heavy rain of between half and three quarters of an inch and lower wind gusts of up to 29 mph before gradual clearing in the afternoon. The predicted daytime high of 72 degrees on Tuesday should be matched on Wednesday.

Thursday’s odds of showers are 20% and look for thermometers to rise slightly to 74 degrees during the day.

The soggy stretch bringing what the weather service calls "beneficial rain" will begin easing by the end of the workweek and Long Islanders can anticipate a sunny but cooler weekend, the National Weather Service’s Islip office said.

Friday may start off with some downpours — the odds of rain are 30%, probably before noon — and it will be 66 degrees, the weather service said.

Saturday, Sunday and Monday all should offer sunny skies and similar daytime highs in the mid-60s.
