A rash of severe thunderstorms accompanied by potentially damaging winds is “likely” to pass through Belmont and most of eastern Massachusetts just before and during the evening rush hour, Tuesday, June 23, according to the National Weather Service. 

There is even a “very low risk of an isolated tornado” and a potential of “golf ball-sized” hail along with torrential downpours and localized floorings, according to the service. 

In a Hazardous Weather Outlook forecast issued at 3:40 a.m., the NWS stated the fast-moving storms, with “damaging straight line winds gusts of up to 70 mph” capable of knocking down trees and power lines, will arrive over Belmont between 3 p.m. and 8 p.m. 

The severity of the storms will depend on how much sunshine the area will see in the morning and just past noon as more sun will heat up the air causing stronger storms as a cold front comes rumbling through the area. 

Hazardous Thunderstorms On the Horizon Saturday for Belmont

After a morning of summer weather, Belmont residents should prepare for stormy weather Saturday afternoon, Sept. 6.

The National Weather Service issued a hazardous weather outlook for Belmont and all of Massachusetts and southern New Hampshire as “a line of showers and thunderstorm will sweep across the region” after 2 p.m. and lasting to 10 p.m.

“There … is a low probability of a very brief, weak tornado,” warned the Service which issued the report at 3 a.m. Saturday.

Torrential rainfall will occur with the strongest storms resulting in a very localized flash flood threat in come areas. A few of the thunderstorms may become severe producing locally damaging wind gusts and perhaps an isolated report of large hail.

If the power does go out, call Belmont Light’s emergency number: 617-993-2800. Don’t call 911.
