.SYNOPSIS...

High pressure builds northeast of the region today as a coastal
trough develops over the local waters. The coastal trough will break
down Sunday into Monday as a weakening front approaches from the
north then begins to stall just north of the local waters into
Monday night. This front will morph into a lifting warm front ahead
of a stronger frontal system as it approaches late Monday into
Tuesday. Southerly winds increase Tuesday near Small Craft levels
with a chance of thunderstorms. The front is expected to push south
of the local waters late Tuesday, then high pressure builds
northwest of the region mid-week as winds subside below Advisory
levels.
