.PREV DISCUSSION...
Issued at 339 AM EDT Thu Apr 16 2026For today, a broad surface
high centered near Bermuda, remains stretched out towards the
west-southwest across Florida and the Gulf Basin. This feature
will slowly begin sliding east in response to a potent shortwave
moving into the Mid-Atlantic and New England States. This will
weaken the pressure gradient and allow for a thermal trough to
develop across the Mainland during the afternoons over the next
several days. This will result in winds, especially across the
areas immediately downwind of the Mainland, to lull during the
morning and afternoon, then peak in the evening and early
overnight.

We continue to monitor a backdoor front that is slated to push
through sometime on Sunday. This front is not expected to bring an
air mass change with it. However, a ribbon of enhanced moisture
will filter in behind this feature. This moisture then looks to
remain trapped across the Keys as a strong high quickly slides in
and settles across the Carolinas through Tuesday. This will result
in a sharp uptick in winds Monday night with windy conditions
returning and lasting through at least Wednesday morning.

.MARINE...
Issued at 1048 AM EDT Thu Apr 16 2026
There are no watches, warnings, or advisories in effect for the
Florida Keys local waters. From synopsis, high pressure over the
central North Atlantic will maintain gentle to moderate northeast
to east breezes through the next several forecast periods. Breezes
likely will lull from late morning into the late afternoon across
the Gulf/Bayside waters due to the heating of South Florida. As
the high moves farther eastward and slowly weakens, easterly
breezes will slacken Thursday through Sunday. A back door front
will slide through sometime Sunday with a strong high pressure
quickly filling in the wake. This will allow for breezes to
freshen with a period of fresh to occasionally strong breezes
possible early next week.
