What forecasters said that day

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 Miami, FL wrote its last area forecast discussion before this small craft advisory went out at Jan 20, 3:24 AM EST, 14 minutes earlier.

Area forecast discussion, Jan 20, 3:24 AM EST, 14 minutes before
Area Forecast Discussion
National Weather Service Miami FL
324 AM EST Mon Jan 20 2020

...Cold front moving through South Florida this morning...

.Short Term (Today and Tonight)...
Some showers have developed ahead of the cold front this morning,
with a focus over the local waters where more ample moisture
exists to support convection. In general, activity early today
should remain shallow showers with spartan coverage. As the front
pushes through the area this morning, a general drying trend is
expected from northwest to southeast throughout the day. Gusty
northwesterly to northerly winds will last overnight with
temperatures falling into the lower 40s over Glades and Hendry
Counties, 40s across the rest of Southwest Florida and inland
Southeast Florida, and mid to upper 50s along the Atlantic coast.
Due to the Atlantic moisture, cannot rule out some shallow showers
over the Atlantic waters which could push near the coast but
things should generally remain dry after the main front pushes
through.

.Long Term (Tuesday through Sunday)...
A shortwave trough will continue to swing southeastward across the
SE CONUS and out over the Atlantic on Tuesday/Tuesday night, helping
induce the formation of a surface low off the Carolina coast. This
developing low will keep the gradient tight and breezy northerly
winds in place over South Florida into Wednesday, when the surface
low finally pushes off further into the Atlantic. This prolonged
period in breezy northerly winds will leave more time for cooler and
drier air to filter in across the area, making Tuesday night into
Wednesday morning the coldest of the period with low temperatures
ranging from the mid 30s west of the Lake/interior SW Florida to the
upper 40s right along the East Coast. While frost is not expected to
be a concern since winds should stay around 10mph or more overnight,
a wind chill advisory (wind chill of 35 degrees or less and winds
over 5 mph for 3+ hours) will be possible for some of the interior
portions of the area.

Wednesday will remain cool under northerly winds with high
temperatures in the 60s. Winds become more easterly Wednesday night
as the surface low to the northwest moves further away, kicking off
a gradual warming and moistening trend stretching into the weekend.
In the meantime, another shortwave trough swinging across Texas will
help induce a surface low over the northwestern Gulf on Thursday.
The shortwave trough begins to phase with the longwave trough as it
rounds the base of it, helping drag the surface low to the northeast
across the Southeast CONUS on Friday. This system should ultimately
drag another cold front through South Florida on Saturday, but with
the loss of upper level support by this time not much convection is
expected. This second front cools things off again but not nearly as
cold as the first front, with low temperatures only expected to dip
into the upper 40s west of the Lake to the upper 50s/near 60 along
the East Coast Sunday night.

&&

.Marine...
Stiff northerly to northwesterly flow behind today's cold front
will allow for hazardous conditions to develop in the Gulf and
Atlantic waters. There will be some brief improvement for the Gulf
but the Atlantic waters could see the hazardous conditions linger
through a good portion of the week. Some initial Small Craft
Advisory issuances will go out with this forecast package but
mariners are advised to stay aware of the latest forecast as
these advisories will likely change in time and require extensions
into the late parts of the week.

&&

.Beach Forecast...
An elevated risk of rip currents will remain along the Atlantic
beaches on this Martin Luther King, Jr. Day with a high rip
current risk remaining along the Palm Beaches again today. The
Gulf beaches will see an elevated rip current risk develop behind
the cold front that may linger through mid-week. Meanwhile on the
Atlantic beaches, the elevated rip current risk will remain
through the week with some of the Palm Beaches maintaining the
risk into the weekend potentially.

&&

.Prev Discussion... /issued 1238 AM EST Mon Jan 20 2020/

Aviation...
Some bouts of sub-VFR cigs (and possibly vsbys) overnight into
the morning hours as showers ahead of a cold front push across
South Florida. Lingering low cigs in the morning should improve by
midday. Gusty northwesterly to northerly flow by afternoon which
should become a tad lighter overnight Monday into Tuesday to close
out the forecast period.

...High Risk of Rip Currents for the Palm Beach County Beaches...

This hazardous weather outlook is for South Florida.

.DAY ONE...TONIGHT

Rip currents: There is a high risk of rip currents along the
Palm Beach County beaches. There is a moderate risk of rip currents
for the Broward and Miami Dade County beaches.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY

After a short lived improvement in marine conditions early in the week,
marine conditions will deteriorate once again particularly across the
Atlantic waters towards the middle of the week behind a cold front
that will move across South Florida on Monday.

The rip current risk is likely to remain high for most of the week
across the Palm Beach coast. It will be lower early in the week for
the Broward and Miami-Dade beaches but go up again in the middle to
latter part of the week.

This cold front moving through on Monday is expected to bring in colder
air to the region for Tuesday and Wednesday. Wind chill values Tuesday
morning may fall into the 30s across portions of inland Southwest
Florida to upper 40s and 50s elsewhere with the temperatures in the
30s across interior and 40s elsewhere by Wednesday morning.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed.
