Area Forecast Discussion
National Weather Service Miami FL
136 PM EDT TUE JUL 12 2016

.AVIATION...
Convection is starting to develop with the sea breeze near the
coast. This is mainly close to KPBI due to a more southeasterly
flow at this time. Expect this convection to continue to develop
in the interior and west this afternoon. Included tempo group for
KPBI which could see some storms producing strong gusty winds. In
the evening hours with loss of daytime heating, convection will
transition to showers and diminish after sunset with light and
variable winds prevailing overnight.

&&

.PREV DISCUSSION... /issued 758 AM EDT TUE JUL 12 2016/

AVIATION...
Light easterly winds will prevail in the early morning hrs along
the Atlantic coast. Sea breeze will enhance isolated showers and
thunderstorms in the afternoon. This showers will mainly affect
the interior. A light to moderate S to SE wind will prevail in the
afternoon and early evening with the exception of KAPF where west
coast sea breeze brings a W to SW wind flow this afternoon.
Lighter winds return during the overnight hours with VFR
conditions.

PREV DISCUSSION... /issued 440 AM EDT TUE JUL 12 2016/

SYNOPSIS...
High pressure will continue to dominate through the weekend.
Slightly above normal temperatures will prevail, with shower and
thunderstorm chances greatest in the afternoons over western
portions of South Florida.

SHORT TERM /Today through Thursday/...
Mostly land areas have stayed dry overnight but scattered
convection has persisted over the waters. Temperatures remain
quite warm, mainly in the lower 80s, and low temperatures may
again near record warm levels today. Monday's low temperature at
KFLL was 83 degrees, breaking the daily record of 81F set last
year.

Slightly enhanced moisture is advecting into the region this
morning, and this will continue through Wednesday. The result will
be greater coverage of diurnal showers and thunderstorms along
sea- breeze intrusions and subsequent boundary interacts. With
east- southeasterly flow in place, the activity will continue to
focus over interior and western sections of South Florida, with
lessening chances closer to the Atlantic coasts. The increased
moisture over the next several days will boost heat indices as
well, with many areas approaching or exceeding 105 degrees during
the daytimes. Ambient temperatures will remain in the low 90s for
maxima and mid-70s to low 80s for minima.

Drier air is forecast to move into the region by Thursday,
suppressing convective coverage.

LONG TERM /Thursday night through Monday/...

It appears, the region will remain in relatively dry airmass
Friday, before increased moisture and minor upper-level
disturbances lead to better rain chances over the weekend. Still,
fairly low rain chances exist across the east coast urban areas,
with best chances over western sections. Maxima should remain near
normal for mid-July, with minima several degrees above normal, in
part due to warm ocean temperatures.

AVIATION...
Generally VFR conditions should prevail through the late morning
hours, followed by another round of afternoon showers and possible
thunderstorms. But since most of the convective activity should
happen closer to the interior today, will refrain from adding
tempos to the tafs and handle the situation with VCTS for now.
Winds are expected to be again dominated by the east coast sea
breeze at around 10 knots. Only exception will be APF where the
west coast sea breeze will bring afternoon periods of west
southwesterly winds.

MARINE...
High pressure will continue to be the main weather
influencer across South Florida waters through the weekend,
keeping prevailing winds out of the east-southeast at around 10-15
knots and seas below 3 feet. Isolated to scattered showers and
thunderstorms are possible through the week, especially over Lake
Okeechobee during the afternoons and early evening. Locally
stronger winds and higher waves can be expected in and near these
thunderstorms.
