Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
912 PM EDT Sat May 18 2024

.SYNOPSIS...

A frontal boundary will remain stalled over our local waters
through Sunday night. The next wave of showers and possibly a few
embedded thunderstorms will occur after midnight through the
predawn hours on Sunday. A break in activity is expected on Sunday
morning, followed by the next round of showers and thunderstorms
during the afternoon and evening hours on Sunday. Strong to
isolated severe thunderstorms will be possible with this activity,
with stronger storms being capable of producing damaging wind
gusts, frequent lightning strikes, and heavy downpours. High
pressure building over New England on Sunday will then wedge down
the southeastern seaboard during the predawn and early morning
hours on Monday, pushing the frontal boundary south of our local
waters. North-northeasterly winds will surge to Caution levels on
Monday, with speeds gradually decreasing on Tuesday and Tuesday
evening as high pressure begins to settle directly over our
waters. Chances for showers and a few embedded thunderstorms will
persist on Monday and Monday night. High pressure will then shift
offshore towards midweek, resulting in prevailing southerly winds
across our local waters.
