Area Forecast Discussion
National Weather Service Miami FL
1246 PM EDT Tue May 21 2024

...New SHORT TERM, AVIATION, MARINE, BEACHES...

.SHORT TERM...
(Rest of today through Wednesday)
Issued at 1226 PM EDT Tue May 21 2024

A weak frontal boundary remains oriented from east to west just
south of the area. Taking a peek aloft, a shortwave remains just
to the northeast gradually shifting eastward into the western
Atlantic waters. 500mb flow on the posterior side of this feature
will maintain westerly to northwesterly mid-level flow across the
region today. The combination of stronger easterly/northeasterly
flow at the surface and north westerly flow aloft will act to
focus sea- breeze driven convection southward across the region,
with the greatest chances of precipitation across our southern
areas (particularly Miami-Dade County and Mainland Monroe) during
the afternoon hours today. Mesoscale models indicate the
potential of an SBCAPE gradient in conjunction with the inward
propagating Atlantic sea- breeze, enhanced ascent along this
boundary will lead to convective initiation during the early afternoon
hours. Although overall severe parameters do not appear to be
too conducive, there will still be the potential for an isolated
strong to severe storm or two across southern portions of the area.

DCAPE values of 1000-1200+ J/kg support the potential of wet
microbursts with the strongest convective updrafts. In addition,
Although the axis of the shortwave has propagated offshore of the
CONUS, South Florida will remain on the periphery of the cold pool
aloft with 500mb temperatures sitting around -9 C. This could
allow for some small hail to fall if a taller core develops. In
addition, although antecedent conditions remain fairly dry across
the southern portions of the east coast metro area, cannot rule
out some pockets of minor urban flooding in vulnerable low lying
locations given the relatively light 500mb flow. High temperatures
will reach the upper 80s to low 90s across the region, with the
warmest temperatures being realized across southwestern Florida.

With the shortwave continuing to propagate to the east on Wednesday,
500mb flow will veer more to a northerly direction in nature.
Combined with northeasterly surface flow prevailing, sea-breeze
circulations will favor convective initiation across the southern
inland portions of our area. As the shortwave continues to propagate
away, 500mb temperatures will continue to warm with 500mb temps in
the -5C to -6C range possible. This will keep the majority of
thunderstorm activity in the garden variety form, although localized
ascent along boundary collisions could still support the potential
of an isolated strong to severe wet microburst if a storm pulses up
and collapses in a quick fashion.
&&

.LONG TERM...
(Wednesday night through Monday)
Issued at 247 AM EDT Tue May 21 2024

During the mid-week period, the mid-level shortwave will
remain situated over the western Atlantic waters to the east of
the Bahamas. A mid-level ridge will also develop and remain
centered over the western Gulf of Mexico during this time frame.
Between these two synoptic features, South Florida will remain in
a light northerly 500mb flow regime with a lack of synoptic
forcing across the area with the subtropical jet located well to
the north of our region. At the surface, ridging situated over the
southeastern United States will allow for relatively light winds
across the region. Therefore, with a lack of the aforementioned
synoptic support, mesoscale patterns, such as the sea-breeze
circulation, will dictate temperatures and the most probable
locations for convective initiation and coverage. Typical
thunderstorm hazards, such as heavy rainfall and gusty winds, will
be possible, but still cannot rule out isolated strong to severe
pulse storms that are able to take advantage of the localized
maximized ascent along boundary collisions even in the background
of a fairly benign pattern.

The mesoscale driven weather pattern will continue for much of the
long-term period as surface ridging remains firmly in place and
synoptic features remain to the north of South Florida. With the
advection of the surface ridge to the east, easterly surface flow
across the region will remain dominant. This will act to feature the
hottest temperatures across southwestern Florida for the time being as
the Atlantic sea-breeze is able to traverse further inland. High
temperatures will range from the upper 80s to low 90s across the east
coast of South Florida to temperatures in the low to mid 90s across
southwestern Florida. Although heat indices will be less oppressive
than the past couple of days, heat safety precautions should still be
followed, especially for vulnerable populations.

&&

.AVIATION...
(18Z TAFS)
Issued at 1226 PM EDT Tue May 21 2024

VFR conditions should prevail through the period as easterly flow
returns to the area. Best chance for showers and thunderstorms
will be across Southern portions of the area today with TEMPOs
added for MIA and TMB airports. Not enough confidence to include
TEMPOs for other sites at this time. L/V flow is expected to
return overnight. &&

.MARINE...
Issued at 1226 PM EDT Tue May 21 2024

Generally benign conditions should prevail across local waters
throughout the period. Locally enhanced winds and seas will be
possible in and around shower and thunderstorm activity across our
area waters.
&&

.BEACHES...
Issued at 1226 PM EDT Tue May 21 2024

With onshore wind flow returning to the east coast of South Florida,
a gradual increase in rip current risks will materialize across the
east coast through the remainder of the work-week. A moderate risk
of rip currents is forecast for Palm Beach County beaches today.
