Area Forecast Discussion...UPDATED
National Weather Service Miami FL
127 PM EDT Wed Apr 12 2023

...New AVIATION...

.UPDATE...
Issued at 941 AM EDT Wed Apr 12 2023

Surface observations and GOES-16 imagery indicate that the warm
front boundary draped across the Florida Keys is beginning to gradually
lift northward over the last several hours. To the north of the
warm front boundary across our area, isentropic ascent has
resulted in light to moderate shower activity developing and
"filling in" across the majority of South Florida. The current
rainfall in addition to the impressive rainfall totals over the
last several days across portions of Miami-Dade and Broward
counties have result in saturated soils and primed antecedent
conditions. Flash Flood Guidance (FFG) demonstrates this well as
the 1 hourly FFG rainfall rates are about 1.5 to 2 inches across
Miami-Dade County. With the eventual propagation of heavier
convection across these same areas over the next several hours,
the flood threat will gradually increase over the next several
hours and remain through the afternoon hours.

On the convective side of the house, the 12z MFL upper air sounding
from earlier this morning indicates some gradual turning with
height. Given the addition of enhanced vorticity along the warm
front boundary, waterspouts could be possible offshore where
instability is more conducive. If strong convection is able to
develop overland, elevated winds in the 970-925mb layer could mix
down and result in gusty winds at the surface. The main concern
today will remain the flooding risk, with the potential of flash
flooding if heavy rainfall persists for a long duration.

No major forecast changes to discuss at this time.

&&

.SHORT TERM...
(Today through Thursday)
Issued at 247 AM EDT Wed Apr 12 2023

An unsettled pattern will continue across South FL today into
Thursday. An upper level low will sit over the northern Gulf today
before crawling northward into the deep south states on Thursday. At
the surface, there is a weak area of low pressure north of western
Cuba, and another area of low pressure over the east-central Gulf.
This low will become the more organized system over the next 24
hours before lifting north towards the northern Gulf coast late
tonight into early Thursday. A nearly stationary boundary to our
south will start slowly lifting north today as a warm front as the
low in the Gulf gets organized, but likely won't actually reach
South FL until late tonight or early Thursday. Ahead of the warm
front, deep moisture will continue to lift north into the area, with
PWAT values over 1.6 inches in most of South FL and 1.8 inches in SE
FL around the east coast metro. This is where the focus of the
heaviest rain is expected today. Latest HREF guidance shows a wide
area of 2-5 inch mean totals from the Homestead area up through
Miami and into the Broward metro. With some instability available,
expect scattered thunderstorms to be very efficient rain-makers
with high rates, so would not be surprised to see several
locations receive over 6 inches today. With this kind of rainfall
over already saturated ground, this will present a problem for
all of the typical poor drainage locations of the east coast
metro. The Flood Watch over portions of Miami-Dade and Broward
will remain in place through 8 PM this evening. While the rain
will take most of the focus today, gradient easterly winds will
remain breezy through this evening, and any stronger thunderstorms
may contain wind gusts that approach severe limits.

The deeper moisture lifts north of the area tonight, and hi-res
models are in fairly good agreement for a break in the rainfall
overnight into early Thursday morning, but will keep chance showers
and isolated thunderstorms in along the east coast. Deeper moisture
returns across South FL during the day on Thursday as the warm front
finally starts to lift north across the area, which will result in
more scattered showers and thunderstorms, this time with the highest
PoPs around the lake region and the northern east coast metro. Will
again have to watch for some flooding issues if heavy rain falls
repeatedly over the same areas.

Rain and cloud cover today will hold high temps into the mid to
upper 70s for most, but lower 80s along the Gulf coast where the
least amount of rain is expected. Low tonight will be in the 60s
inland to lower 70s across the east coast metro. Went a bit lower
than guidance for high temps on Thursday, but should still reach the
low to mid 80s over most of the area.

&&

.LONG TERM...
(Thursday night through Tuesday)
Issued at 247 AM EDT Wed Apr 12 2023

The aforementioned low pressure system and associated cut-off low
will continue their track northeastward on Friday, skirting along
the edges of an upper level trough moving across the Midwest US.
The surface low will continue to drag the previously stalled
boundary northward, taking much of the moisture-rich air along
with it. Nevertheless, sufficient moisture will remain for another
afternoon of scattered showers to materialize, over northern
portions of the CWA, around lake Okeechobee and across local
Atlantic waters.

The drying trend will continue on Saturday as dry air aloft filters
into the area, which should lead to fair weather to start the
weekend and give us a break from the relentless rain. Unfortunately,
dry air will not last as another frontal boundary could approach the
area by late Sunday which will draw more Gulf moisture across the
area to end the weekend into early next week which should be our
next shot at scattered to numerous convection across eastern metro
areas Sunday and Monday afternoon. Given this is at the tail end of
the long term period, take it with a grain of salt for now as timing
can change depending on the evolution of the synoptic features to
our north.

Temperatures will continue to gradually warm into the weekend, with
high temperatures across interior South Florida possibly reaching
the upper 80s  on Friday, then the lower 90s on Saturday and Sunday.
Along the East Coast, temperatures will remain in the mid 80s
through the weekend. With another frontal boundary approaching at
the start of next week, temperatures could once again cool down
across much of South Florida.

.AVIATION...
(18Z TAFS)
Issued at 121 PM EDT Wed Apr 12 2023

VCTS will remain in the forecast for the TAF sites through 00Z
with a tempo group for IFR conditions for ceiling and vis from the
showers and thunderstorms. The winds will remain easterly over the
TAF sites through 00Z before going SE after 00Z. VCSH between 00Z
and 03Z before going dry tonight for the overnight hours.

&&

.MARINE...
Issued at 247 AM EDT Wed Apr 12 2023

East to southeast winds 20-25 kts early today subside to 15-20 kts
by this evening, except for the northern Atlantic waters where
elevated winds will continue into late tonight. Atlantic seas
around 10 feet early today subside to 4-7 feet by this evening.
Gulf seas 4-7 feet this morning subside to 2-4 feet this evening.
SCA was extended through 18Z today for Lake Okeechobee, Biscayne
Bay and the Gulf waters. The SCA for the Atlantic waters runs
through 00Z this evening for the southern waters and 09Z for the
northern waters.

&&

.BEACHES...
Issued at 247 AM EDT Wed Apr 12 2023

Strong easterly flow and northeast swell will result in a
continued high risk of rips for the Atlantic beaches today. Even
though the easterly flow weakens and becomes more southeasterly on
Thursday, a lingering swell will still result in a high risk of
rips through Thursday evening.

In addition, large breaking waves in excess of 7 feet in the surf
zone will continue through early this afternoon, so a high surf
advisory remains until 2 PM.
