Believe it or not: The weather on both the Fourth of July and the following Saturday might not be rainy.

After months of seemingly endless weekend rain, the National Weather Service is — tentatively, this is the weather after all — forecasting that both Friday’s Independence Day festivities and the first day of the weekend should be mostly to partly sunny, with highs comfortably in the 80s and much more manageable humidity.

“Obviously, take that with a grain of salt. It’s still nearly a week out,” National Weather Service Meteorologist Kyle Pederson told the Herald on Sunday.

Monday will be hot — Pederson said it will be close to 90 degrees — and it will feel like it as the dewpoint climbs toward an uncomfortable 65 degrees.

Tuesday will be more of the same, according to the meteorologist, with another 90 degree day expected but the dewpoint even more unforgiving at 70 degrees.

“It’s going to feel quite muggy, especially on Tuesday,” Pederson said.

The following pair of days, “we stay warm, with highs closer to 85 degrees,” Pederson said, but the dewpoints will fall closer to 60 degrees as a colder weather front enters the region.

That cooler air will likely bring along thunderstorms Tuesday evening, according to the weather service, with sporadic severe storms possible locally.

“I think we’ll see pretty widespread storms,” Pederson said.

Localities hit by severe thunderstorms, he said, could see wind gusts upwards of 60 mph. Elsewhere, he said, it’s likely to be continuously “breezy” with wind speeds closer to 20 mph.

While there is a slight chance of precipitation on Thursday evening, Pederson said, Friday’s holiday activities should occur under a clear sky with a high in the low to middle 80s. The dewpoint that day, Pederson said, should be “comfortable” at about 55 degrees.

For families looking to take in a Fourth of July fireworks display: the temperature on Friday night is forecast to fall toward the middle 60s and stay mostly clear, according to the weather service.

After weeks of Saturday rain, the region may have another reason to celebrate after Independence Day. That’s because, of the 26 Saturday forecasts Boston has seen so far this year, all but six have included wet weather.

“Starting from January 4, 20 Saturdays so far this year have had some form of precipitation,” Pederson said.

This weekend, however, the forecast for the first half of the weekend is entirely absent any mention of rain, according to the weather service.

“It looks pretty good right now,” Pederson said. “Hopefully it stays that way.”
