The workweek was wrapping up Friday with the chance of scattered showers and thunderstorms, at least into the evening hours, forecasters said.

“Widely scattered showers and t-storms moving through until about 8 pm tonight,” the National Weather Service’s Upton office said in a tweet. Gusts of 30 to 40 mph are possible, as well as brief bouts of heavy rain.

Starting around midafternoon, there was a 20 percent chance for a pop-up shower or thunderstorm, though chances for that were higher in areas of Connecticut and the lower Hudson Valley, said Tim Morrin, weather service meteorologist in Upton.

Unlike with larger-scale storm systems moving from one location to another, Friday’s possible precipitation would be the result of more localized instability in the atmosphere, he said.

It’s a regular summertime weather pattern in which small pockets of air may warm and rise, leading to cooling, condensation and possible showers, depending on how much moisture is present, he said.

Forecasters can determine when overall conditions are ripe in an area, with any showers that do pop up being random and short-lived — though, given the right circumstances, potentially severe, he said.

“We start out with some very nice weather,” News 12 meteorologist Rich Hoffman said Friday morning. “We have some beach weather coming our way today and tomorrow.”

The high temperature Saturday will be about 73 degrees, the weather service said.

There is a 40 percent chance of rain during the day Sunday, and a 70 percent chance of rain Sunday night, the weather service said.
