Area Forecast Discussion
National Weather Service Miami FL
128 PM EDT Wed May 27 2020

.Aviation...
Scattered SHRA and isolated TS developing across the interior are
pushing eastward this afternoon. This activity is expected to
continue through 00Z this evening. MVFR to IFR CIGs/VIS can be
expected during the stronger activity, along with sporadic gusty
winds. TEMPO groups have been added for FLL/FXE/MIA/OPF/TMB for
IFR conditions due to storms as the line approaches. May need
additional TEMPO groups/AMDs as the afternoon progresses. VFR
conditions return overnight with rain chances increasing tomorrow
afternoon. Patchy fog possible early Thursday morning.

Prev Discussion... /issued 1024 AM EDT Wed May 27 2020/

Update...
The area of low pressure dumping over a foot of rain over
portions of the east coast the past few days is now Tropical Storm
Bertha, which has just made landfall along the South Carolina
coast with maximum sustained winds of 50 mph. A series of weak
upper-level impulses look to slide over South Florida today
whereas the ridge of high pressure refuses to build in across the
area. Consequently, wind flow (and the steering flow) will
continue to have a slight southwesterly component. What does this
mean? Well, any showers and/or storms that do develop across the
interior of South Florida today will push eastward towards the
east coast metro areas yet again.

From MFL's 27/12Z sounding, some drying is evident, though PW's
are still well above normal for this time of year. The sounding
measured 1.59 inches this morning, which is about 2.5 standard
deviations above normal, or in the 99.5 percentile. 500 mb
temperatures are also slightly cooler today, at about -7 to -8
degrees C. This will once again allow for some steepening of mid-
level lapse rates to occur by this afternoon. The plethora of
moisture across South Florida should once again be readily
available for convection to tap in to today, especially with the
combined effects of the sea breezes and upper-level impulses.

Currently, meso-models are suggesting that Palm Beach and Broward
counties will be the focus of activity for this afternoon into the
evening hours, however some southward trends in guidance are
evident and Miami-Dade County will have to be watched closely,
especially since standing water and flooded roadways are still
evident this morning with a Flood Advisory in place.

Unfortunately, if the east coast metro areas were to see more
rainfall today, it will not take long for flooding to spike up
once again, especially since the last three days, Broward County
has seen 6 to 10 inches of rain, Palm Beach COunty has seen 5 to 9
inches of rain, and Miami-Dade has seen 8 to 15 inches of rain.
One hour FFG is about 1 to 2 inches across portions of metro
Miami-Dade with 2 to 4 inches for Broward and Palm Beach
counties.

With the rainfall accumulations seen the past 72 hours, in
Layman'sterms, the east coast of Florida is deluged. Therefore,
wouldn't be surprised if additional flood advisories or warnings
are needed this afternoon and evening given the projected rainfall
and sensitivity of these areas to additional rainfall.

Lastly, given sufficient precipitation loading and DCAPE over 1000
J/kg, a few stronger wind gusts are possible today in any taller
thunderstorm cores, and perhaps even strong showers. The cooler
temperatures aloft suggest that lightning activity may be a little
more widespread today as well.

The HWO has been updated accordingly.

Hydrology...

Deep tropical moisture continues to be in place across South
Florida. As a result, several rounds of showers and thunderstorms
capable of producing torrential rainfall across the outlook area
through at least tonight can be expected, especially for the metro
areas of Palm Beach, Broward, and Miami-Dade counties.

Instantaneous rainfall rates, on average, look to be around 2 to
4 inches per hour, with locally higher amounts possible,
especially over locations that receive multiple rounds of showers
and thunderstorms. Another round of showers and thunderstorms,
with heavy rainfall, will be possible later this afternoon and
evening along the east coast due to southwesterly flow.

Interests across South Florida are strongly encouraged to monitor
the latest information from the National Weather Service in Miami
to prepare for the potential of heavy rain and flooding.

Discussion...

Short Term (Through Thursday):

Some fog will be possible this morning and again tonight given
the saturated soils and light winds. A more typical summer-like
pattern is expected today and tomorrow with both seabreezes
expected to develop during the afternoon. Southerly to slightly
southwesterly winds today will allow the focus for afternoon
showers and thunderstorms to be mostly over the interior and Lake
Region, however a few storms will still be possible along the East
Coast with the greatest chance for Palm Beach/Broward. Given
saturated soils, the metro areas will remain sensitive to
additional heavy rainfall. Tomorrow, the flow becomes slightly
more easterly, putting the focus for afternoon showers and
thunderstorms more over the interior and Lake Region. High
temperatures will be warm both days, ranging from the upper 80s to
low 90s.

Long Term (Thursday Night - Tuesday):

Models depict a mid-UL trough/low complex gradually weakening while
migrating towards the eastern seaboard for the beginning of the
weekend. Meanwhile, sfc ridging extends into the southern half of
the Florida peninsula from the western Atlantic, resulting in a
prevailing easterly flow across the area. This synoptic scenario
will result in a summer-type weather pattern with showers and
thunderstorm activity developing near the east coast in the early
afternoon hours, then shifting to interior areas and the west coast
through early evening hours as sea breezes push inland.

By early next week, model solutions for the long term suggest the
formation of an upper level low over the northwest Atlantic waters,
which seems to weaken the aforementioned ridge and allow for a back
door frontal boundary to reach South Florida. Winds turn more NE and
become moderate to gusty at times as pressure gradients between the
front and a low developing over the west Caribbean Sea become
tighter.

Expect chances of rain to remain mainly in the scattered range early
next week,  with best chances over the interior and west coast metro
areas. Temperatures will continue generally warm, with afternoon
highs in the upper 80s to low 90s.

Marine...
Other than occasional showers and thunderstorms, generally benign
marine conditions are expected through the weekend. The gradient
tightens some next week as a system begins to approach the area.

Beach Forecast...
A moderate risk of rip currents is forecast for the East Coast
today.
