1207 PM EDT Wed Aug 26 2026
.SYNOPSIS...
A stalled frontal boundary positioned just north of the Georgia
waters will remain in place during the next several days.
Thunderstorms developing over coastal locations will push across our
local waters through Friday, mainly during the afternoon and evening
hours, with strong to isolated severe storms possible, mainly over
the near shore waters. Offshore winds will otherwise prevail
during the overnight and morning hours, with the Atlantic sea
breeze shifting winds to onshore each afternoon across the near
shore waters. Southerly winds will then surge each evening, with
speeds briefly approaching Caution speeds around sunset outside of
ongoing thunderstorm activity. Stronger high pressure building
over New England this weekend will shift prevailing winds to
onshore across our local waters, with scattered showers and
thunderstorms possible at any time during the upcoming weekend and
early next week.
