LI forecast: Chance of rain Monday, high temperatures rest of week

Potential showers and temperatures as high as the 90s are included in Long Island’s forecast this week, according to the National Weather Service.

Long Islanders should expect a cloudy start to their workweek on Monday with showers likely before noon and a high near 80 degrees. The chance of precipitation is 60% with new rain amounts between a quarter and half of an inch possible.

At night, the low will be about 69 with partly cloudy skies and a light northwest wind of around 5 mph.

A 20 % chance of showers and Thunderstorms before 3 p.m. is forecast for a sunny Tuesday as temperatures are expected to rise to the low 90s. A 20% chance of showers and thunderstorms continue in the evening before 9 p.m. as temperatures will be in the low 70s.

“We have a cold front coming through on Tuesday, there could be a couple showers associated with it, but it should not be as widespread as the showers we’re expecting on Sunday into Monday,” said Matthew Wunsch, a weather service meteorologist in Upton. “As we get into midweek high pressure settles over the area between systems and it actually gets really hot again.”

Wednesday's forecast includes a sunny day and a high near 90. The evening will remain mostly clear with a low near 73.

Thursday will likely be the hottest day of the week with a high in the mid-90s and sunny skies. Temperatures drop to the mid-70s at night with mostly clear skies.
