GMZ600 Synopsis For Pascagoula Ms To Okaloosa Walton County Line Fl Out 60 Nm Including Major Area Bays And Sounds- 1027 Am Cdt Sat Aug 17 2019
Synopsis..Surface high pressure will become better established from the western atlantic to the north central gulf through midweek leading to a better southwest wind flow through midweek. Better coverage of showers and Thunderstorms can be expected, especially Sunday through Monday, as a weak frontal boundary near the coast early today shifts inland.

near term now through Saturday night ... A weak mid level trof
still stretching from eastern sections of sc and ga to the NE gulf
near apalachicola fl will gradually shift NE through tonight
mostly in response to a passing mid to upper level shortwave
tracking eastward from the central plains states to the mid to
upper ms river valley today and tonight. Near the sfc a weak
frontal boundary still draped near and along the al and nwfl coast
early this morning will slowly shift inland and weaken later
today and tonight as a well defined seabreeze circulation develops
near the immediate coast and begins to slowly shift inland by
midday. South of the front better moisture in the boundary layer
is noted with surface dewpt temps ranging from the middle to upper
70s. With this pattern a big difference in humidity levels will
develop by this afternoon with rh values in the upper 20 to lower
30 percentile range over northern sections of the forecast area
and the lower to middle 60 percentile range near the immediate
coast. Where the better moisture is located expect isolated to
scattered showers and thunderstorms to form especially along and
south of the front early today, generally over the adjacent gulf
waters of al and nwfl mostly west of pensacola, and over coastal
locations of nwfl further east towards fort walton beach and
destin. This is where the best coverage of showers and
thunderstorms will form over land later today as the seabreeze
move inland. Latest model soundings show plenty of dry air still
present above 5 kft over coastal areas today with ml capes ranging
from 2500 to 3000 j kg suggesting any thunderstorms that do form
by mid to late afternoon could be briefly strong accompanied with
gusty straightline winds, frequent cloud to ground lightning and
short periods of very heavy rain. As a result anyone near the
coast or along the beach should stay tuned to local radar trends
during the afternoon and early evening hours.

With good subsidence and less cloud cover still present to the
north throughout the day afternoon temps will climb to the upper
90s to near 100, especially along and east of the i-65 and north
of the i- 10. Further west and along the coast highs will range
from the lower to middle 90s. Lows tonight will trend a little
warmer compared to last night ranging from the middle 70s for most
inland areas and the upper 70s to near 80 along the immediate
coast. 32 ee
short term Sunday through Monday night ... An upper level ridge
of high pressure stretching from southern portions of tx to the
north central gulf of mexico early Sunday morning is forecast to
retrograde westward through Sunday night, while a secondary upper
level ridge axis meanwhile continues to extend from the western
atlantic to the eastern fl peninsula. A weak mid to upper level
flow pattern will prevail across our forecast area between these
features. Despite the weakness aloft, short range model guidance
indicates that the bulk of deeper moisture will remain oriented
from the northern gulf of mexico through the fl big bend and
adjacent southern georgia Sunday afternoon, with another zone of
enhanced moisture over southeast la and portions of southern ms
and far southwest al. A slightly drier and more subsident airmass
may continue to extend across interior portions of our forecast
area through Sunday night. A weak surface trough axis will extend
over interior portions of the forecast area on Sunday afternoon,
which could aid in the development of some convection, but given
the overall pattern, we have opted to reduce pops from the previous
forecast over interior parts of our area for Sunday, with only
20-40% convective coverage now indicated. A better chance of
showers and storms will reside over the southern third of our
region within the zone of higher moisture, and will have chance
pops in the morning increasing to likely (~60%) by Sunday
afternoon. A persistent low level thermal ridge will allow
temperatures to warm into the lower to mid 90s over inland areas,
while readings in the upper 80s to around 90 degrees are
anticipated near the immediate coast. Maximum heat indices will
range from 100-105 degrees over most of the area, with a few spots
possibly reaching between 105-108.

Convection should become more isolated to scattered in coverage
during the evening hours, with more numerous coverage becoming
focused from near the immediate coast to the offshore waters.

Overnight lows will range in the lower to mid 70s inland and in
the mid to upper 70s along the coast.

A weak inverted low to mid level trough is forecast to develop
from the north central gulf of mexico through the fl big bend and
adjacent southern ga on Monday in the weakness between the pair
of ridges. An associated plume of deeper moisture will return back
into our area Monday and will combine with ample instability to
bring increased coverage of showers and storms to our region. We
will keep likely pops going across much of the area during the
day, before becoming more isolated to scattered in nature Monday
evening into late Monday night. High temperatures may be a couple
of degrees cooler, but still ranging from the lower to mid 90s
inland and in the upper 80s to around 90 near the immediate
coast. 21
long term Tuesday through Friday ... An unsettled weather pattern
will continue through much of next week as a persistent mid level
trough continues to extend over the vicinity of the north central
gulf coast region. Daily precipitable water values will continue
to average between 1.75" and 2" along this feature, and will
combine with the available afternoon instability to produce
scattered to locally numerous showers and thunderstorms each day.

Convective coverage will tend to decrease in the evening overnight
hours inland, with higher coverage becoming focused offshore.

High temperatures should continue to range in the lower to mid 90s
inland, and in the upper 80s to around 90 along the immediate
coast. Lows each night will continue to range in the 70s. 21
marine... High pressure near the surface will become better
established from the western atlantic to the north central gulf
through early to mid week leading to a light to moderate west to
southwest wind flow over the marine area later today through
midweek. Seas are expected to build to 2 to 4 feet offshore with
this pattern later today through mon. Winds and seas will be
higher near scattered to numerous showers and thunderstorms
forming mostly along and south of a weakening frontal boundary
that shifts inland later today and tonight. 32 ee

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
