Massachusetts snow forecast: Up to 8 inches, ‘hazardous conditions’ for commute, power outages and flooding possible

It’s deja snow all over again.

Except this time, wicked heavy rain comes on the back end of the storm system.

Yet another snow event hits Massachusetts on Wednesday as flakes should start flying in the afternoon. There’s a chance that a burst of heavy snow could happen during the afternoon commute for parts of the Bay State, leading to hazardous conditions on the roads.

The Boston-area could see up to 3 inches of snow, while areas west of Interstate 495 could get up to 6 inches of snow. The Berkshires could see up to 8 inches.

“The farther north and west you go, the more snow is expected,” Andrew Loconto, meteorologist at the National Weather Service’s Boston office, told the Herald.

Then as warm air moves in from the south, the snow will change to rain during the evening. More than an inch of rain is expected through Thursday.

“All that snow should be washed away by rain in the Boston-area,” Loconto said.

The rain may cause some flooding, which could be problematic for the Boston-area during the Thursday morning commute.

Thousands of Bay State households were still in the dark on Tuesday following Monday’s winter storm, and there will yet again be a risk for power outages with this storm coming on Wednesday. Strong wind gusts could topple tree limbs and power lines.

The National Weather Service’s Boston office has issued alerts for winter weather hazards, wind-related hazards, flooding hazards and coastal hazards with this storm system.

A “Winter Weather Advisory” is in effect from Wednesday afternoon to early Thursday morning for much of Massachusetts.

“Plan on slippery road conditions,” the advisory reads. “The hazardous conditions could impact the evening commute… Slow down and use caution while traveling.”

A “Wind Advisory” is in effect from Wednesday night to Thursday morning for southeastern Massachusetts, Cape Cod and the Islands. Strong wind gusts up to 50 mph are expected.

“Gusty winds could blow around unsecured objects,” the advisory reads. “Tree limbs could be blown down and power outages may result… Use extra caution when driving, especially if operating a high profile vehicle. Secure outdoor objects.”

Also, a “Flood Watch” is in effect from Wednesday evening through Thursday morning. Forecasters warn that a period of heavy rain combined with snowmelt could spark street and poor drainage flooding, along with rises on area rivers, creeks and streams.

The advisory reads, “Those living in areas prone to flooding should be prepared to take action should flooding develop.”
