What forecasters said that day

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

NWS Miami, FL wrote its last area forecast discussion before this gale warning went out at Feb 18, 12:37 PM EST, 53 minutes earlier.

1237 PM EST Sun Feb 18 2024

...New AVIATION...

.UPDATE...
Issued at 837 AM EST Sun Feb 18 2024

Some forecast changes as the forecast evolves with today's event
starting to come into focus. Starting off, the boundary meandering
across southern Miami-Dade County will likely serve as a
convective focus for any strong to severe storms that develop and
potential for excessive rainfall accumulations. The latest Day 1
Outlook from the Storm Prediction Center captures this marginal
risk of severe weather well. One factor inhibiting convection
north of the boundary is a relatively well-entrenched surface
inversion. The morning 12z MFL sounding shows a convective
temperature of 81 degrees F which will be difficult to meet today.
Actually trimmed back temperatures a degree or two in most areas
as the observed trends with this morning's warm up were quite
muted.

On the flip side, along and south of the boundary, convection has
been developing and quickly zipping east-northeastward. Key West
radar has shown several discrete supercell-like features
attempting to develop but as of yet they have not been able to tap
into the deeper shear evident on the morning sounding. At some
point, the expectation is that some more stout convection will
develop and be able to better access the conditionally favorable
environment to produce the localized threat of severe weather
including 60+ mph winds and tornadic activity.

Moving into the overnight period, guidance continues to trend
higher with regards to the wind and associated gusts on the
backside of the exiting low. By Monday morning, it is possible
that frequent gusts to gale force could materialize over the
Atlantic waters. A Gale Watch has been posted from 06z tonight to
06z Tuesday. Even beyond the Gale Watch, Small Craft Advisories
previously were posted through 00z Wednesday. We will continue to
monitor both the low track and how the winds on the back side
materialize. The threat of a wake low developing cannot be ruled
out which could enhance wind speeds on Monday and necessitate a
Gale Warning and possibly a Wind Advisory for portions of the
peninsula. The current boundary position continues to be south of
where previous guidance runs had placed it and the stronger winds
to the north could end up translating southward accordingly.

&&

.SHORT TERM...
(Today through Monday)
Issued at 245 AM EST Sun Feb 18 2024

An approaching cold front will drive an increase in shower and
thunderstorm chances early this morning. Over the coming hours,
convective coverage is expected to increase overnight through
the morning hours, most of South Florida will wake up to a cloudy
and increasingly rainy Sunday. A low level jet will develop over
the southern portions of the peninsula which could help enhance
rainfall amounts and allow for more stout convection, especially
if a surface low is able to develop and move across the peninsula
on its way to the Atlantic. Amounts of 2 to 3 inches cannot be
ruled out in localized areas, particularly if an area were to see
the accumulation in a few hours and is prone to flooding due to
poor drainage. A few strong thunderstorms may be possible mainly
across Southern portions of the area this afternoon just south of
the front, although the more widespread activity should remain in
the form of showers.

Shower and thunderstorm activity should begin to wane pretty
rapidly after sunset as the parent low pushes into the western
Atlantic. A few showers will be possible on Monday on the backside
of the low, but most of the day should remain dry - especially
the latter half of Monday.

As the boundary is expected to push through the area through
the day today, temperatures could vary widely across the area.
Highs should generally reach the lower 70s for southeast portions
of the area but could remain in the 60s for northern and southwest
portions of the area.

Models depict the surface low migrating eastward and moving away
from the peninsula by early Monday, with high pressure quickly
building across the region in its wake. A more stable and drier
air mass will follow, with most of the showers ending before noon
on Monday.

&&

.LONG TERM...
(Monday night through Saturday)
Issued at 245 AM EST Sun Feb 18 2024

The majority of the rest of the week should remain fairly stable
as broad and deep high pressure firmly establishes over the SE
CONUS, with little to no rain expected each day. Temperatures will
remain near or just below normals through the middle of the week
as cool air advection prevails. Expect highs to remain in the
upper 60s north to low 70s elsewhere through Wednesday, then
gradually warming up into the mid-upper 70s towards the weekend.
Lows will likely drop into the 40s/50s through Thursday and then
warming up on Friday as the high shifts to the east and southerly
flow returns.

&&

.AVIATION...
(18Z TAFS)
Issued at 1236 PM EST Sun Feb 18 2024

Sub-VFR through much of the period with bouts of IFR/LIFR cigs and
vsbys. TS possible this afternoon which may require short-fused
TEMPOs. Gusty winds with convection today will become breezy and
northwesterly tonight into Monday morning. Gradual improvement out
of IFR/LIFR may take longer than current forecast period at some
sites.

&&

.MARINE...
Issued at 245 AM EST Sun Feb 18 2024

Generally southwest flow will prevail today ahead of a frontal
boundary. Wind speeds will be increasing through the day, with
10-15 kts expected early morning, but quickly increasing to 20 to
25 kts with gusts to 30 kts as the boundary passes. By late
afternoon to early evening, surface flow is expected remain breezy
and veer to a more northwesterly behind the boundary.

&&

.BEACHES...
Issued at 245 AM EST Sun Feb 18 2024

An elevated rip current risk will continue along the Atlantic
beaches through a good portion of the week. The rip current risk
will increase along the Gulf beaches in the wake of the cold front
today into early portions of the week as well.

...Strong to Severe Showers and Thunderstorms Today...
...Developing Hazardous Marine and Beach Conditions...

This Hazardous Weather Outlook is for Atlantic coastal waters,
southeast Florida, southern Florida, southwest Florida and Gulf of
Mexico.

.DAY ONE...Today and tonight.

Rip Currents: There is a moderate risk of rip currents for the
Palm Beaches and Gulf coast.

Heavy Rainfall: Widespread showers and isolated thunderstorms are
expected to impact the area through most of the morning and
afternoon hours today. Localized flooding could be an issue,
especially for low-lying or poor drainage areas of the east coast
metro. 1-3 inches of rainfall is expected with localized higher
totals possible.

Thunderstorms: There could be a few isolated strong to severe
thunderstorms this afternoon, with highest risk across southern
portions of the area.

Wind: The strongest thunderstorms could contain wind gusts up to 60
mph especially across the southern areas.

Tornado: An isolated tornado cannot be ruled out with the strongest
thunderstorms mainly across the southern portion of the peninsula.

Waterspouts: An isolated waterspout is possible with the strongest
thunderstorms in the Atlantic and Gulf waters.

Marine: Southwesterly winds will become northwesterly and will
increase to 20 to 25 kts this afternoon across the Atlantic waters.
Winds will also increase over the Gulf and Lake Okeechobee waters
tonight creating hazardous marine conditions.

.DAYS TWO THROUGH SEVEN...Monday through Saturday.

The rip current risk will be increasing across the Atlantic beaches
during the early to middle portion of the week. An elevated risk of
rip currents will continue on Monday for the Gulf beaches. High surf
will develop along the Atlantic beaches, particularly off the Palm
Beaches for Monday.

Hazardous marine conditions will continue over the Atlantic waters
through the middle of the week as winds remain elevated and seas
continue to build due to a developing northeasterly swell. Wind gusts
to gale force are possible early Monday morning through Monday night.
Wave heights in the Gulfstream could build in excess of 10 feet.

.SPOTTER INFORMATION STATEMENT...

Weather spotters are encouraged to report high wind, hail, and
flooding to the National Weather Service forecast office in Miami.
