.SYNOPSIS...Weak low pressure developing over the Gulf of Maine
late this morning will move off to the E of the area later today
and tonight. A weak cold front extending SW from the low will
move SE over the area behind the low today into early tonight,
and then become nearly stationary over the S waters later
tonight. The front should slowly dissipate Mon as high pressure
builds in. The high will move E Mon night and Tue ahead of a
slow-moving cold front. The front will likely reach the coast Tue
night, and then weaken as it drifts offshore Tue night and Wed.
Another slow-moving cold front will approach the coast Wed night
into Thu, and finally push offshore Thu night.
