.SYNOPSIS FOR MID ATLC WATERS...Rapidly intensifying low pressure
just NE of the waters early this morning, will move NE being over
Newfoundland, Canada by tonight. High pressure gradually builds E
behind the low today, being over the area tonight and early Wed
before moving E of the N and central waters during the day Wed. A
warm front will move NE over the N and central waters Wed,
followed quickly by a cold front that passes across the N and
central waters Wed night, and through the S waters Thu. High
pressure builds E again for Thu night, except for a trough or
weak low pressure along the SE coast continuing into early Fri.
Otherwise, high pressure will be over the area Fri, shifting E
late Fri and Fri night ahead of yet another cold front. This
front moves across the waters Sat. A secondary cold front moves
into the waters Sat night, becoming stationary over the central
waters, under weak high pressure.
