What forecasters said that day

The local office's own words before this special weather statement 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 special weather statement went out at Nov 5, 8:02 PM EDT, 46 minutes earlier.

Area forecast discussion, Nov 5, 8:02 PM EDT, 46 minutes before
Area Forecast Discussion
National Weather Service Tampa Bay Ruskin FL
802 PM EDT Fri Nov 5 2021

.DISCUSSION...
An upper level trough/low on the north-central Gulf coast this
evening shifts across north FL by morning then eases northeastward
off the eastern seaboard during Sat. A low pressure center just off
the mouth of Tampa Bay this evening tracks northeastward...across
the state overnight then out over the Atlantic Sat...with a cold
front trailing back to the southwest.

While there is currently a break in the widespread convection from
earlier today the features noted above will provide a moisture
atmosphere with enough instability and lift to support widely
scattered robust thunderstorms throughout the rest of the night.
Although the loss of daytime heating will help inhibit instability.
A few storms could pose the risk for mainly damaging winds. A
weak tornado or waterspout may be possible but the potential for
a strong/sustained one appears low. After daybreak Sat the
convection begins to lift north and is expected to clear the
entire area by afternoon.

As the surface low and front move away strong northwest winds
spread across the Gulf...creating hazardous beach conditions for
at at least part of the weekend. Both a High Rip Current Risk and
a High Surf Advisory start tonight and continue into Sun. Cooler
air will work in with temperatures running a few degrees below
seasonable.

&&

.AVIATION...
06/00-06/24Z. Generally prevailing MVFR/LCL IFR CIGS with SCT
SHRA/ISOLD TSRA continue overnight and drop to IFR for all terminals
overnight. As the low pressure and front move away VFR CIGS and NSW
move in from the west Sat.

&&

.MARINE...
We have had a few special marine warnings issued today and
anticipate having a couple of more before the night is out. Offshore
buoys have reported some gusts to 25 knots. These winds will
increase throughout the night as they shift from northeast to
northwest and continue into early Sun...with dangerous boating
conditions. High pressure begins to build in during
Sun...allowing winds and seas to start to slowly subside.
