Area Forecast Discussion
National Weather Service Tallahassee FL
1011 AM EDT SAT AUG 27 2016

.NEAR TERM [Through Today]...
With a strong deep-layered ridge established north of the region,
easterly flow will continue today. 12z KTAE sounding indicates
significant dry air in the 700-500mb layer, which should limit any
long-lived updrafts from developing. Guidance forecasts this dry
air to remain in place through the afternoon, which will limit
coverage of showers and thunderstorms. Expect best chances right
along the panhandle coast, and along the eastern border of the CWA
as the east coast seabreeze approaches this afternoon. Otherwise,
expect hot and dry conditions across the remainder of the area.

.PREV DISCUSSION [343 AM EDT]...

.SHORT TERM [Tonight Through Monday]...

We will see little change in the overall pattern with the deep
easterly flow continuing as east to west oriented ridging remains
north of the local region. Atmospheric moisture will gradually
increase especially on Monday as moisture associated with a tropical
disturbance begins to surge northward up the Florida peninsula and
eastern gulf. There still remains a lot of uncertainty with the
possible development and track of this feature but additional impact
on our weather, if any, will be beyond the short term period. The
highest PoPs through the period (30-50%) will mainly be across the
Florida zones and local coastal waters. High temperatures will be
in the lower to mid 90s with lows in the lower to mid 70s.


.LONG TERM [Monday Night Through Saturday]...

The extended forecast is complicated because there hasn`t been
any run to run consistency between the models in handling the
evolution (strength and position) of the tropical disturbance
which is forecast to be in the eastern gulf at the beginning of
the period. The 00z GFS tracks a weak system slowly to the
northwest and then inland over LA on Thursday. The latest ECMWF
tracks a very weak system westward into the central gulf on
Wednesday before dissipating this feature in the western gulf on
Thursday. Due to the uncertainty, we will not make any significant
changes to the current extended forecast at this time. Regardless
of development, people in our forecast area, especially at the
coast, should at least prepare for the possibility of heavy rain
and hazardous boating and beach conditions next week.


.AVIATION [Through 06Z Sunday]...

VFR conditions will prevail through the TAF with the possibility of
a few showers at ECP and VLD late in the afternoon.


.MARINE...

With a surface ridge to our north, winds will continue from the east
at moderate levels during the overnight and early morning hours, but
become lighter (especially at the coast) during the afternoon and
early evening hours. By early next week the conditions will depend
greatly on the development and track of a disturbance disturbance
currently approaching south Florida.


.FIRE WEATHER...

Hazardous fire weather conditions are not expected over the next
several days.


.HYDROLOGY...

No organized heavy rain is expected through Monday. By Tuesday the
threat for heavy rain may begin to increase, though the global
models have the heaviest rain totals over the Gulf of Mexico and
across central FL.
