area forecast discussion
national weather service miami fl
755 pm edt Sat aug 17 2019

Aviation
PrimarilyVFR conditions are expected through the period. Another
round of showers and thunderstorms are expected across the area
tomorrow, but the best coverage should shift more towards the
interior and west coast. Therefore the east coast TAF sites have
been left dry for now, although an isolated shower or storm cannot
be ruled out along the seabreeze.

Convective focus shifting to SW florida this week...

discussion...

this afternoon and evening: we saw a peak in convective activity
over the last few hours with things generally winding down as
activity pushes northward along the southerly flow. Boundaries
will provide the focus for any remaining convection, particularly
as the afternoon winds down into the evening.

Overnight: tonight should be drier than last night with a
noticeable lack of convection over cuba this afternoon to fuel an
outflow boundary that could initiate convection over the waters
again tonight. Slightly drier air will also help cut off the
amount of convection but the warm, rich surface moisture over the
atlantic and gulf waters will provide an environment where shallow
convection could definitely persist overnight and any interactions
by that convection with boundaries could lead to some strong
thunderstorms. For the forecast, most high resolution guidance was
fairly dry so adjustments were made for the gridded forecast to
illustrate that low end rain and thunderstorm chances focused over
the waters tonight.

Sunday: slightly drier air advecting into the area from the east
on Sunday will help to cap convective coverage but convection
should still be able to get going with the sea breezes. The
easterly flow regime will favor the convective focus over the
interior and west coast. Morning showers becoming early afternoon
thunderstorms along the sea breezes near the coasts are in the
forecast with the majority of the rain chances over southwest
florida, particularly inland portions along the state road 29
corridor, on Sunday afternoon. Temperatures will continue to be
warm with a degree or so above the consensus blend preferred for
the forecast in most areas.

Monday-Wednesday: with the surface ridge of high pressure reaching
into the region from the atlantic to start the week, the surface
trough and associated pooled moisture will remain north of the
area. A weakness in the mid to upper level ridge will begin to
develop which may allow a trough to return over the peninsula of
florida. This small shift in pattern could allow for an increase
in convective coverage but the easterly to southeasterly pattern
through mid- week should keep the focus of convection over
southwest florida and the interior. The national hurricane center
continues to monitor the surface trough to our north in case
tropical development were to occur (formation chances per the 2 pm
edt tropical weather outlook remain low through the next 5 days).

To the south, a tropical wave pushing across the caribbean could
bring some additional moisture to the region, particularly if a
surface trough breaks off the northern portion of the wave and
moves into the region Monday into Tuesday.

Thursday-Saturday: easterly to southeasterly flow will persist
into the end of the week with a pattern that favors a continued
convective focus over southwest florida and the interior. Another
northern trough from a tropical wave traversing the caribbean
Friday into Saturday could again bring additional moisture into
the region to close out the extended forecast period. With these
waves, the convective activity could be more widespread temporally
instead of focused along the more normal diurnal pattern.

Marine...

a more typical pattern for august with south southeast flow this
weekend becoming east southeast into the upcoming week as the
ridge axis from atlantic high pressure builds over the region and
shifts northward. With prevailing speeds generally less than
10kts, seas will be 2 feet or less for all waters. The main
boating concern will remain scattered showers and storms, where
winds and waves could be locally higher in and around any
activity.

Hydrology...

while much of the area remains saturated, a lack of widespread
coverage the last couple of days has allowed the ground to
tolerate heavy rainfall a bit better the last couple of
afternoons. With a shift to easterly to southeasterly flow, the
greatest concern for flooding from repeated rounds of afternoon
convection day after day will shift from the east coast metro
towards southwest florida. Locally heavy rainfall anywhere in
south florida could still cause minor flooding over the coming
days, but those with interests over in southwest florida
particularly should monitor conditions and the forecast over the
coming week.

Fisheating creek at palmdale is currently at 6.14 feet with
additional heavy rainfall from thunderstorms over portions of the
basin in northern glades and highlands counties occurring the
afternoon. The forecast trend is an expectation for fisheating
creek to gradually rise over the coming days. At this time, all
the ensemble guidance continues to maintain the creek below flood
stage at palmdale.
