.Synopsis for Stonington ME to Merrimack River Ma out to 25 NM
Weak surface high pressure will linger over the coastal waters
through Thursday. The high humidity will keep sea fog conditions
in and out, particuarly overnight and early morning through that
time. The fog will erode behind a cold front Friday, as drier air is
ushered in to the waters. Some choppy conditions possible on Thursday
night into Friday, but another surface high pressure will return
fair boating conditions for the weekend.
