Dry conditions should persist through Thursday and Friday before a new storm develops, which is likely to bring widespread rain and possibly some thunder around the coast.
With temperatures in the 40s and 50s, Thursday should start with sunshine, the last of the week before clouds take shape in the afternoon, according to the National Weather Service.
Then a weak warm front is expected to arrive Thursday night, potentially developing the chance for some light rain or light wet snow in higher terrain, forecasters said. Overnight lows are expected to be in the mid-30s, and any snow should accumulate mostly on unpaved areas across southern New England. This is expected to end by Friday morning.
Friday should see temperatures back in the 40s, with winds picking up between 10 and 15 mph, forecasters said.
Much later in the day, a slow-moving trough over the Appalachians is expected to deliver the wet weather forecasters anticipate. Pressure from the coast is likely to transition the rain from light to moderate soaking.
It remains unclear when and where the rain could get heavy, but forecasters expect a half inch of rain to fall, with closer to 3 quarters of an inch or greater for southeastern Massachusetts and Rhode Island for Saturday. Temperatures should repeat on Saturday, back in the 40s.
The region’s southern coast also has a limited risk of thunder as this storm develops, forecasters continued.
By Sunday, a low-pressure system should bring with it some drier air and alleviate wet conditions, the weather service said. The overall storm system should leave the region by early next week, with a warm front to follow and potentially more rain early Tuesday.
Temperatures should warm up during this timeframe, in the low 60s and high 50s, until temperatures dip on Wednesday, forecasters noted. More unsettled weather could follow, leaving the possibility of another weekend storm.
