Synopsis for Massachusetts and Rhode Island coastal waters

As a storm sweeps E from the Mid-Atlantic today, high pressure
builds across the region immediately after persisting through
midweek. By late week, we'll see another weak cold frontal system
stall as it approaches the region, lingering into the weekend.
Lifting, turning warmer, all prior to a more potent frontal system
for early next week.

For information on possible hazardous weather beyond the 24-36
hour forecast period, please visit www.weather.gov/boston and
follow the Current Hazards link above the map on the left.
