.Synopsis for Massachusetts and Rhode Island coastal waters...
A backdoor cold front will stall out tonight near or just north of
Cape Cod Bay. This boundary will lift briefly back as a warm front
across our northern waters early Wed morning. This will be very
short-lived as this boundary will drop back south across our waters
late Wed morning and afternoon...shifting winds to the NE.
High pres over Quebec will result in gusty NE winds across the
waters Thu. This high will then shift east and be followed by a
couple waves of low pres tracking across Quebec Fri into the
weekend...which may result in winds turning to the SW at times.

.Synopsis for Massachusetts and Rhode Island coastal waters...
A backdoor cold front will stall out tonight near or just north of
Cape Cod Bay. This boundary will lift briefly back as a warm front
across our northern waters early Wed morning. This will be very
short-lived as this boundary will drop back south across our waters
late Wed morning and afternoon...shifting winds to the NE.
High pres over Quebec will result in gusty NE winds across the
waters Thu. This high will then shift east and be followed by a
couple waves of low pres tracking across Quebec Fri into the
weekend...which may result in winds turning to the SW at times.
