The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Tampa Bay, FL wrote its last area forecast discussion before this small craft advisory went out at Apr 11, 1:48 AM EDT, 2 hours 1 minute earlier.

...New AVIATION...

.AVIATION...
(06Z TAFS)
Issued at 147 AM EDT Thu Apr 11 2024

Ahead of an approaching cold front, a strong gradient favors gusty
winds through the day. Episodic bouts of wind shear are also
possible, especially through sunrise where less wind is mixing down
to the surface. A line of thunderstorms is then forecast to move
through the region later this afternoon, with a window for impacts
timed out and being highlighted in TAFs. With strong winds already,
it is not much of a stretch to see some pretty strong winds mix down
as these storms move through, as well as a short-lived window for
IFR with passing storms. Rapid improvement in conditions is expected
as the storms and associated cold front clears out. No major
concerns thereafter are expected.
