.SYNOPSIS...

High pressure centered over our local waters this morning will shift
eastward this afternoon, with this feature becoming centered near
Bermuda by late Saturday. A cold front will shift southward towards
our area on Tuesday, possibly bringing widely scattered showers and
thunderstorms to our local waters. High pressure will briefly
strengthen along the Mid-Atlantic coast in the wake of this frontal
passage, with this feature wedging down the southeastern seaboard,
providing for breezy onshore winds from Tuesday through Thursday.
Scattered showers and thunderstorms will be possible late next week
