The weekend may not be a total washout, but Long Islanders will still see a big shift in weather conditions to the rainy, muggy and unsettled side, forecasters say.

Look for some sunshine early in the day Saturday, with clouds increasing and a sprinkle or so of rain in the afternoon, said Tim Morrin, National Weather Service meteorologist in Upton. Showers were expected to start showing up around 5 to 6 p.m., he said.

As for ocean beaches Saturday, look for a moderate risk for rip currents in the morning, becoming a high risk from 2 to 9 p.m.

Then, rain, some heavy with any thunderstorms that develops, was likely for Saturday night into Sunday around noon, Morrin said, with gusty winds in the mix.

The Island could see 1 to 2 inches of rain, locally higher with some thunderstorms, which would likely lead to areas of urban and poor drainage flooding, the weather service said in a hazardous-weather statement. Some flash flooding also is possible.

Still, there was some uncertainty as to where heaviest rain would fall, as of late Friday afternoon. Any part of the forecast area, Long Island included, has a potential to see as much as 2 to 2.5 inches of rain, Morrin, said. 

Also, although there’s no high probability, a weak tornado can’t be ruled out, said Jay Engle, also a weather service meteorologist. 

The system brings “strong winds and heavy rain threat,” said Rich Hoffman, News 12 Long Island meteorologist.

Temperatures climb only to mid-to-upper 70s Saturday, with increased humidity, the weather service said.

As for Sunday, it's expected to be warm and humid with the heaviest rain ending by noon, though there’s still a 60 percent chance for precipitation throughout the day, Morrin said.

And the rain's not stopping there. Each day next week through Friday was looking at chances of showers and thunderstorms, the weather service said.

That’s because a flow of humid air from the south makes ongoing conditions “quite muggy,"  Engle said.
