Massachusetts could see its first snowfall of the season on Friday or Saturday, according to the National Weather Service.
Snow might coat the region at some point over the weekend, likely at night on Friday or Saturday, although forecasters do not yet know exactly which parts of the state could be impacted and how many inches might fall, said Frank Nocera, a meteorologist with the service.
“There are some indications that there could be one or two possible chances of snow,” he said. “But it’s way too early to get specific.”
The anticipated flurries could either come in two small events or one moderate one, although “neither one looks like a blockbuster event,” Nocera said.
Historically, Massachusetts usually reports its first inch of snow during the first week of December, so the weekend forecast is not too surprising to forecasters, Nocera said.
“Technically, we’ll be a little bit behind schedule” for snow, he said.
Clouds start gathering Monday evening as temperatures drop into the 30s overnight.
The clouds will thicken overnight heralding the arrival of a new, much more turbulent, weather system that will push temperatures into the 50s and generate cloudy, gusting conditions throughout Tuesday, forecasters wrote.
Showers will roll into the Greater Boston Area on Tuesday afternoon, picking up overnight and then tapering off Wednesday morning but lingering through the afternoon, said Bill Simpson, a meteorologist with the service.
Forecasters expect about an inch of rain in the area by the end of the day Wednesday, Simpson said.
Winds in Boston Tuesday night will range between 25 to 30 miles an hour while a hazardous weather alert has been issued for Bristol, Essex, Plymouth counties and the Islands.
“Strong, to potentially damaging, southerly winds are forecast, with sustained values upwards of 35 to 40 miles an hour, gusts up to 45 miles an hour,’’ forecasters wrote. “Widespread rain will fall, with embedded heavier showers, resulting in rainfall amounts around an inch in a brief period of time.”
