Weather / Marine Zone Forecast
Cloudy, 39°F
Feels Like 32° F
Today’s High 52°F
Wind, SSW 9 mph
Humidity 61%
Visibility 10.0 mi
Pressure 29.68 in
Variable cloudiness with a couple of showers.
Synopsis for Massachusetts and Rhode Island coastal waters:
A frontal system pushes across the waters on this afternoon into the
this evening, bringing scattered showers. Low pressure associated
with this frontal system will intensify into a gale center
along/near the Maine coast tonight into Thursday, with strong WNW
winds across the MA and RI waters. High pressure brings light winds
and dry weather Friday. An inverted trough of low pressure moves up
the eastern seaboard Friday night into the weekend. This will likely
result in showers, possibly heavy at times. In addition, increasing
ENE winds this weekend into early next week, in response to high
pressure over Quebec and developing low pressure along the Carolina
coast. This will result in building seas.
