While fireworks and cannons are what many are expecting this coming Friday Fourth of July, the weather could be just as explosive early on this holiday weekend. But while much of the talk has been directed southward with the possible development of the season's first tropical storm, a major cold front sweeping from the Midwest is likely to disrupt your holiday plans. At 5:35 a.m. today, Tuesday, July 1, The National Weather Service has issued a hazardous weather forecast for eastern Massachusetts beginning Wednesday night, July 2 with "a few strong thunderstorms are possible late Wednesday into Friday afternoon. "These storms could approach severe levels" with the main threat being "isolated damaging wind gusts with a secondary concern for large hail." The NWS said the most likely place for this weather to occur is west of Worcester. Yet forecasts are indicating that July 3 and Independence Day will be wet in the area with rain anticipated for both days. "There is the potential for widespread heavy rain and localized flash flooding Thursday into Friday night," according to the NWS. The latest news from down South is that the tropical depression now lingering off the east coast of Florida will strengthen and head up the Eastern Seaboard but will be pushed out into the Atlantic by the cold front that will be bringing the rain into Belmont. But it will likely increase the surf and tides along the New England coast beginning on Saturday.
