Area Forecast Discussion
National Weather Service Miami FL
423 PM EDT SUN AUG 7 2016

.SYNOPSIS...

The major synoptic features across the region include a broad
surface trough across  the northeastern Gulf with a weak surface
low across the northeast Florida peninsula. Additional features
include a large amplitude upper level low centered across the
northwest Bahamas islands and surface high pressure east of the
Florida peninsula extending westward to eastern South Florida. As
a result there is extensive cloudiness across the eastern Gulf
with embedded showers and thunderstorms and widespread showers and
thunderstorms across much of the Florida peninsula.

&&

.DISCUSSION...

There is general agreement amongst the global models that similar
synoptic features mentioned above will continue across the region
through at least mid-week if not late into the week. The models
suggest that the upper level low across the northwest Bahamas will
gradually drift northwest tonight through Monday, and the surface
low slowly lift north through this period. However, there would
still be a surface broad low across the northern and northeast
Gulf with deep tropical moisture and extensive cloudiness across
the central and eastern Gulf that would encompass South Florida
and adjacent waters. Low level winds will be south to
southwesterly which will advect deep tropical moisture across the
region.

Forecast for Monday and Tuesday...Forecast soundings suggest that
regional  PWAT's will be above two inches through Monday and
Tuesday with low level winds south to southwesterly. While near
climatological values, mid-level temperatures will be sufficient
for convective potential and forecast soundings also indicate
regional instability. Thus, across most of the peninsula on Monday
and Tuesday numerous afternoon/evening showers and thunderstorms
are forecast with more scattered activity across the Gulf and
Atlantic waters although in the near shore waters more widespread
coverage may be expected.

Rip currents...With winds, seas and lack of swell unfavorable for
rip currents, only a slight risk of rip currents is expected
through early this week for both the Atlantic and Gulf coast
beaches.

Forecast for Wednesday through late week...The extended global
model consensus continues to suggest that the broad surface trough
across the northeastern and northern Gulf could persist into mid-
week and possibly longer while slowly drifting west but still
broad enough to result in deeper moisture persisting across the
northeastern Gulf and the Florida peninsula. Deep easterly flow
could return later in this period as higher surface pressure tries
to build across the region. The extended guidance indicates diurnally
driven afternoon/evening showers and thunderstorms although the
greatest coverage would be in the interior regions and not across
the entire peninsula as forecast for Monday and Tuesday.

&&

.MARINE...

Generally southerly to southeasterly winds of 15 knots or less
are forecast through Tuesday then becoming generally
southeasterly to easterly by mid-week through late week. Regional
seas of 2 feet or less are forecast through most of the forecast
period.
