Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
1050 AM EDT Thu May 9 2024

.SYNOPSIS...

A squall line of strong to severe thunderstorms is expected to
traverse the Georgia waters during the mid to late afternoon hours
today, with this line reaching the northeast Florida waters during
the late afternoon and early evening hours. This squall line is
expected to weaken after sunset as it approaches the waters south
of St. Augustine. Strong to severe thunderstorms will be capable
of producing damaging wind gusts, hail, and frequent lightning
strikes. Otherwise, a cold front will enter the southeastern
states tonight and will progress southeastward across our local
waters on Friday afternoon and evening. Additional rounds of
strong to severe thunderstorms will be possible after sunrise and
again during the afternoon hours ahead of this front. Winds will
shift to northwesterly in the wake of the frontal passage on
Friday night and Saturday morning, with weak high pressure the
expected to build eastward from the Ozarks on Saturday night,
reaching the coastal Carolina region by Monday afternoon. This
weather pattern will result in onshore wind development on Sunday
afternoon, with onshore winds then strengthening on Monday night
ahead of an approaching warm front. Showers and thunderstorms will
overspread our local waters by late Monday night as this warm
front lifts northeastward across our area.
