Area Forecast Discussion...UPDATED
National Weather Service Miami FL
135 PM EDT Thu May 18 2017
.AVIATION...
The winds will be easterly around 20 knots this afternoon before
decreasing to around 10 to 15 knots tonight over the east coast
taf sites. The winds at KAPF taf site will also be easterly with
speeds around 15 knots with gusts up to 25 knots this afternoon
before decreasing to around 10 knots tonight.
A few showers will continue to affect the east coast taf sites
this afternoon into tonight, but the coverage will be few and far
between to put into the taf sites at this time. Therefore, the
east coast taf sites will remain dry at this time. The VCSH will
continue for the KAPF taf site this afternoon, as there are more
coverage of showers over this area. There could even be a
thunderstorm late this afternoon, but the coverage will be few and
far between to put into the KAPF taf site at this time.
The ceiling and vis will also remain in VFR conditions outside of
any shower or thunderstorm passage. Therefore, the taf sites will
remain in VFR conditions at this time for this afternoon into
tonight.

.PREV DISCUSSION... /issued 918 AM EDT Thu May 18 2017/
UPDATE...
High pressure will remain over the western Atlantic waters today,
as a weak low remains over the western Caribbean Sea. This will
keep the pressure gradient tight over South Florida today allowing
for a breezy to windy easterly wind flow. Isolated to scattered
showers will continue to develop over the Atlantic waters and work
west into the mainland area of South Florida today. There could
be a few thunderstorms over the western metro areas late this
afternoon due to an increase in moisture and the heating of the
day. Therefore, pops will remain in the 20 percent range over the
eastern areas of South Florida this afternoon with 30 percent
over the western areas.
The 12Z MIA sounding this morning showed 20 knot winds just above
the surface around 900 ft. These winds should easily mix down to
the surface through the afternoon hours. Therefore, an SCA has
been put up for the Atlantic and Biscayne Bay waters today into
tonight for the wind speeds.
Rest of the forecast looks good at this time and no other changes
are expected at this time.

UPDATE...BNB/LK
PREV DISCUSSION... /issued 733 AM EDT Thu May 18 2017/
AVIATION...
High pressure to the east, will keep breezy conditions across
South Florida through the TAF period. Wind will continue to be
easterly around 15 knots with some gust up to 25 knots by mid-
day. Also, isolated to scattered showers will move across the area
through the TAF period. Therefore, including VCSH in all TAFs.
May see some occasional brief MVFR cigs, along the east coast
terminals with cloud bands/SHRA, but overall cigs expected to
remain VFR.

DISCUSSION...
NEAR TERM /THROUGH 6 PM THURSDAY EVENING/...
As of 340 AM EDT...Surface high pressure remains located near
Bermuda early this morning with ridging aloft. The synoptic
pattern remains similar to recent days, with brisk to occasionally
breezy east to southeasterly flow due in part to a tight pressure
gradient on the southern periphery of the high. Periodic showers
continue to drift into portions of the east coast metro early this
morning, with generally brief light rain. Low temperatures are
again on the mild side, with most areas only seeing temperatures
dipping into the upper 70s, with lower 80s reported along the east
coast urban corridor.
For today, brisk to breezy east/southeast flow will continue to
prevail, with the strongest winds along the east coast where gusts
of 20-25 mph will be common. Periodic isolated to scattered showers
will be possible, with slightly more focused activity expected
across portions of the interior and Gulf Coast with the strong
easterly flow in place. Any Gulf Coast sea breeze development looks
rather limited with the stronger easterly flow in place today.
A few thunderstorms will also be possible especially this afternoon
and early evening, with lightning and brief heavy rain being the
main threats. High temperatures today will range from the mid and
upper 80s east to lower and mid 90s west.
SHORT TERM /6 PM THURSDAY EVENING THROUGH SATURDAY NIGHT/...
Brisk to occasionally breezy east/southeast flow will continue into
the short term period with little change in the synoptic pattern, as
high pressure remains locked in the western Atlantic basin. This
flow pattern will continue to yield isolated to scattered showers
along with a few storms, more focused during the afternoon and
evening hours over the interior and Gulf Coast. During the night,
additional showers will continue to be possible mainly across
eastern areas. It will continue to feel more like summer with high
temperatures in the mid/upper 80s to lower 90s and mild nights with
low temperatures generally in the 70s. It will continue to feel
humid as well with gradually increasing low-level moisture and
dewpoints in the 70s.
LONG TERM /SUNDAY THROUGH WEDNESDAY/...
The long term period will start with a continued brisk
east/southeast flow regime across the region, as hints of a more
typically established wet season pattern become more apparent.
Increasing low-level moisture and diurnal heating will lead to
isolated to scattered showers and thunderstorms through the
period. Daytime activity will likely be focused across the
interior and Gulf Coast, with nighttime activity more focused
across the east coast and Atlantic waters. By early next week, the
flow may shift more southerly ahead of a developing upper-level
trough over the central CONUS, which may increase moisture further
and lead to more coverage in showers and thunderstorms.
Temperatures will be near to slightly above average.
MARINE...
Small Craft Advisory in effect for the Atlantic waters including
Biscayne Bay until 6am...
Strengthening high pressure building near Bermuda will lead to
increasing east/southeast winds across the local waters over the
next several days. Small craft will need to exercise caution across
much of the local waters, especially the Atlantic where winds will
be close to 20 knots, but expected to generally be just below
criteria once the current advisory expires early this morning.
Seas will generally be 2-4 feet, but briefly reach 3-5 feet at
times in the offshore Gulf and 3-7 feet in the Gulf Stream. Seas
will generally be 4 feet or less by the weekend. There will be
isolated to scattered showers and thunderstorms over the next
several days.
BEACH FORECAST...
Breezy easterly flow will lead to a High Risk of rip currents for
the Atlantic beaches today, and continuing through at least the
end of the work week.
