GMZ600 Synopsis For Pascagoula Ms To Okaloosa Walton County Line Fl Out 60 Nm Including Major Area Bays And Sounds- 1025 Pm Cdt Sun May 26 2019
Synopsis..A surface ridge stretching west over the northern gulf of mexico will continue through late week, bringing a mainly light southeast to south wind to the marine area through Thursday night. Winds may increase slightly by the end of the period as the high pressure shifts east and a frontal boundary moves into the southeastern states and stalls well north of the marine area. Little change in seas expected, although a slight building of waves expected by late Wednesday into Thursday due to the persistence of the wind flow.

discussion...

key points:
*for the atlantic beaches, adequate onshore flow will continue to
support a high risk for rip currents through at least Monday.

After Monday, the beaches of palm beach county will experience
the highest potential for rip currents, though elevated rip-
current potential will exist for all atlantic beaches at times
through much of this week.

*generally dry conditions are expected into the middle of this
week. Thereafter, gradual veering of low-level flow to more east-
southeasterly will facilitate an influx of sufficient moisture
for gradually increasing precipitation chances -- especially from
late this week into next weekend. While widespread precipitation
is unlikely, an increase in moisture is expected later in the
week into next weekend.

*elevated fire-weather conditions may occur each afternoon from
Monday through Wednesday for interior sections of south florida
westward toward the gulf coast.

Technical discussion:
goes-16 total precipitable water loops indicate ample deep dry air
over the southwest north atlantic waters -- supported by differential
anticyclonic vorticity advection -- well east of a prominent
midlevel anticyclone elongated from the lower mississippi valley
to north florida. Easterlies throughout much of the troposphere
along the southern flank of the anticyclone continue advecting
this dry air across the forecast area. Meanwhile, the
aforementioned subsidence is maintaining a zonally elongated
surface ridge over the atlantic waters off the central fl coast,
which trails westward over the north gulf. The pressure gradient
surrounding this feature is maintaining occasionally breezy
easterly winds across the local area.

For early this upcoming week, another in a series of troughs is
forecast to deepen and amplify over the western and central states,
which will correspond to the maintenance of downstream ridging
across the southeast states and vicinity. As a result, the overall
surface pressure pattern and related sensible weather are not
forecast to undergo substantial modification across south florida.

This will maintain adequate onshore flow for continued rip-current
potential for the atlantic beaches, as addressed below. Meanwhile
the continued influx of dry air across the region, coupled with
occasionally breezy winds, will support elevated fire-weather
conditions across interior sections of south florida, also addressed
below.

By middle to latter portions of this week, the previously
mentioned trough is forecast to gradually develop east-
northeastward over the CONUS well north of the forecast area,
after phasing with a migratory, lower-latitude impulse. The
eventual progression of the phased disturbances will facilitate
localized weakening of the midlevel anticyclone. Meanwhile, the
southwestern north atlantic tropospheric subsidence will gradually
lessen build eastward as a downstream midlevel shear axis
advances eastward. In response to these developments, surface
ridging north of the area will tend to focus more eastward over
the southwest north atlantic, resulting in a tendency for low-
level flow to gradually veer to more east-southeasterly by late
week. This will foster a gradual influx of moisture for later
this week.

The increase in moisture is forecast to support slight chances for
precipitation as early as Wednesday over the coastal waters.

However, it should not be until late this week into the weekend when
additional moisture transport into the area supports further
increasing precipitation chances. This would especially be the case
if the southern extent of low-level meridional flow -- responding
to the passage of the phased midlevel disturbances -- encourages
additional moisture influxes for next weekend, as indicated by
some medium-range model guidance. Regardless, without stronger
forcing for ascent, the potential for widespread precipitation is
expected to remain low.

Otherwise, temperatures are not expected to deviate significantly
from normal readings into next weekend.

Marine...

occasionally breezy easterly winds are expected through early parts
of this week, before winds gradually become more east-southeasterly
later this week. Wave heights of generally 2 to 4 feet are
expected over the atlantic coastal waters, with wave heights of
generally 1 to 2 feet over the gulf coastal waters. Dry conditions
are expected through early this week, with gradually increasing
chances for showers and thunderstorms starting on Wednesday.

Beach forecast...

for all atlantic beaches, a high risk for rip currents remains in
effect through at least Monday. After Monday, elevated rip-
current potential is expected to persist at times through much of
this week. This will especially be the case for the beaches of
palm beach county. However, established rip-current channels will
further substantiate the elevated rip-current risk for all
atlantic beaches through the week, even as surface winds gradually
veer for mid to late week supporting a marginal decrease in the
onshore-flow component.

Fire weather...

the maintenance and reinforcement of a dry air mass across south
florida is expected to support minimum relative humidity as low as
the middle and upper 30s across interior sections westward toward
the gulf coast. These relative humidity values, combined with
occasionally breezy winds and adequately dry fuels may support
elevated fire-weather conditions each afternoon from Monday through
Tuesday, and possibly on Wednesday. However, without stronger
surface winds, critical fire-weather conditions are unlikely.
