As conditions in Massachusetts remain dry on Wednesday, more unsettled weather is expected to return going into the last weekend of March.
While some showers may exit off of the coast Wednesday night, skies should clear up as a dry column arrives, according to the National Weather Service. A deep mixing could also bring about dry air and wind gusts reaching 25 mph.
Temperatures on Thursday should reach the low to mid-40s across higher terrain, while the rest of the interior should see temperatures at around 50 degrees, forecasters said. A shortwave trough could bring potential rain or snow showers ahead of a cold front, but forecasters anticipate an increase in cloud cover.
Winds should pick back up again to over 20 mph on Friday, with forecasters not ruling out any potential showers. But on Saturday, forecasters expect a “backdoor” cold front to enter southern New England. These cold fronts are common during the spring and move south along the Atlantic seaboard and the Great Lakes, according to the weather service.
“Uncertainty is still rather high regarding how far south the front will drop, but it is increasingly likely it may bisect somewhere across southern New England for a period of time,” forecasters wrote.
While temperatures are likely going to struggle to reach 45 degrees north of the cold front, temperatures south of it could reach around 70 degrees, forecasters said. Widespread rain should also fall on Saturday, but forecasters have not ruled out some snow or ice in higher terrain across the borders between Massachusetts, Vermont and New Hampshire.
This backdoor front should lift by Monday as a low from the Great Lakes enters the region, bringing with it a surge of warm air and winds, forecasters said.
“The middle of next week is also quite tricky to nail down given high uncertainty this far out,” forecasters wrote. “Regardless, the low over southern Ontario looks to lift out, and a high is likely to build in over the Great Lakes Tuesday and Wednesday.”
