.SYNOPSIS FOR NEW ENGLAND WATERS...A weak front across the
northern Gulf of Maine will drift S and become stationary
tonight, and then return N as a warm front Mon. Elsewhere, weak
high pressure will develop later today into Mon before shifting E
of the waters later Mon. Intensifying low pressure will track E
and NE from the Great Lakes Mon night into Tue, reach Maine by
Tue night, and the Canadian Maritimes Wed. A strong cold front
associated with the low will move E over the waters late Tue and
Tue night, followed by a secondary cold front moving SE over the
area Wed into Wed night. A high pressure ridge will build E
toward the coast Thu and Thu night as low pressure forms E of the
waters. The ridge will reach the coast Fri and move offshore Fri
night.
