243 PM EST Fri Jan 9 2026
.SYNOPSIS...
Strong high pressure centered off the New England coast will
continue to wedge down the southeastern seaboard this afternoon
before this feature shifts further offshore in advance of an
approaching cold front. Southwesterly winds will gradually
strengthen after midnight on Saturday night ahead of the approaching
cold front, with winds shifting to westerly and increasing to
Caution levels offshore on Sunday morning as the front crosses our
local waters. Scattered showers will accompany the frontal passage,
with winds then shifting to northwesterly and increasing to Small
Craft Advisory levels on Sunday afternoon and night, with occasional
gusts to Gale Force possible as high pressure builds over the
Tennessee and lower Mississippi Valleys. High pressure will then
gradually weaken over the southeastern states on Monday night and
Tuesday, allowing winds to shift to northeasterly while gradually
diminishing.
