After some Thursday morning showers, more scattered showers could arrive in the afternoon with some thunderstorms.
Meteorologists Mark Dixon and Scot Haney said some cool air aloft will be unstable as low pressure passes over New England.
"As we head through the peak of the day's heating, with colder air aloft, scattered showers and even some thunderstorms will likely develop," Dixon said.
A few of those storms could produce small hail and gusty winds.
"We'll be monitoring the situation from the Early Warning Forecast Center," Dixon said.

"However, this will be more the exception than the rule," Haney said. "Severe weather is not expected."
Friday is expected to be the pick of the week in terms of gorgeous weather.
"Thanks to high pressure, we can look forward to a mostly sunny day with highs in the mid-to-upper-70s over interior portions of the state," Haney said.
Temps in the greater Hartford area could peak at 78 degrees.
Coastal area like Groton and Stonington should have highs between 65 and 70 degrees due to an onshore breeze.
Haney said the Early Warning Forecast team is keeping an eye on a coastal storm that could bring rain to the state on Saturday. He said whether or not it rains depends on the storm's track.
"As of now, rain still looks to play a role later Saturday into early early Sunday, then Sunday afternoon, another round of rain could develop," Dixon said.
Any lingering rain on Sunday morning should quickly leave. Therefore, much of the day should be dry.
"However, a deep trough of low pressure high above the ground will linger over the Eastern United States." Haney said. "Therefore, any sunshine that develops Sunday will just cause more clouds and showers to build up during the afternoon."
Haney said a few thunderstorms are possible.
Without rain, weekend temperatures should be in the lower 70s. With rain, they could hover in the 60s.
