GMZ600 Synopsis For Pascagoula Ms To Okaloosa Walton County Line Fl Out 60 Nm Including Major Area Bays And Sounds- 1020 Pm Cdt Thu Sep 20 2018
Synopsis..High pressure will slowly build over the north central gulf through early next week, leading to mostly a light to moderate east to southeast wind flow over the marine area through Tuesday. Winds and seas will be locally higher in isolated to scattered showers and Thunderstorms through the forecast period. A better southerly flow is expected by midweek in response to a weakening frontal boundary approaching from the north.

06z issuance... Isolated showers are expected to develop near shore
during the late night to early morning hours followed by isolated
to potentially scattered showers and storms developing over the
area through the day. Patchy fog with ifr MVFR conditions is
possible mainly over inland areas late tonight. MVFR conditions
will accompany the showers and storms withVFR conditions
otherwise expected. Light and variable or calm winds tonight
transition to a southeasterly flow at 5 to 10 knots on Friday. 29

discussion... See updated information for land areas below.

Update... Have updated to increase pops this evening for
lingering convection mainly over wilcox county and advancing into
covington okaloosa counties. Removed pops for the rest of the
night over the western half of the area. Made additional
adjustments to sky cover trends. Remainder of forecast is on
track. 29

00z issuance... Isolated convection currently over the area tapers
off this evening. A few showers will be possible near the coast
late tonight into the early morning hours, then isolated to
possibly scattered showers and storms develop over area later into
the morning into the afternoon. MVFR conditions will accompany the
showers and storms, and patchy fog with ifr MVFR conditions is
expected mainly inland late tonight, but otherwiseVFR conditions
prevail. Light and variable winds tonight become southeasterly 5

Marine... Did a quick update to the current marine forecast
mainly to reflect current conditions a little better. A light to
moderate southeast wind flow will diminish and become mostly east
late tonight and early Fri morning. 32 ee

near term now through Friday ... An amplified pattern noted on
upper air analysis charts today with 20.12z maps showing a deep
layer ridge axis (h50 height anomalies +6 +12 decameters) centered
over the tn river valley and carolinas. East and west of the
ridge was a trof axis over the southwest atlantic and the other
gradually moving eastward out of the four corners of the desert
southwest. Overall, an assessment of deep layer moisture over the
past 24 hrs (pwats 1.80 to 2.0") has changed little and mostly
confined over the florida peninsula, stretching westward over the
central gulf coast. Lower pwat air is found over the interior and
up across northern al eastward to the carolinas under the upper
ridge. Latest mesoscale scale analysis of instability shows
surface based capes having risen to between 2500 to 3500 j kg over
the southern half of the local area and with the presence of
adequate environmental moisture, isolated showers and storms have
been initiating and moving slowly northward with propagating
coastal sea-breeze boundary mostly along and north of i-10. The
mitigating factor for increased storm coverage thus far is the
presence of the anomalously deep ridge aloft just to our north and
its larger scale subsidence.

A small chance of showers and storms this evening, before decreasing
late in the night. Mid level ridge axis slips gradually east to off
the mid-atlantic coast going into Friday. On the southern periphery
of this feature, an upper level low, pinching off the southwest
atlantic upper trof, migrates westward across the fl peninsula to
the eastern gulf. At the surface, high pressure persists over the
western atlantic, ridging southwest into the southeastern u.S.

And northern gulf. This maintains a moist southeast flow over the
local area. Thunderstorms are expected to develop thru the course of
the day Friday with an increased coverage expected, aided by a
deeply moist and unstable airmass and a weak region of diffluent
flow aloft between the high level ridge to the northeast and
approach of eastern gulf upper low. Focus should start along the sea
breeze during the morning as it begins to push inland, followed by a
more scattered coverage during the afternoon. Before any cooling
influence of storms, daytime highs Friday look to range 3 to 6
degrees above climatology. 10
short term Friday night through Sunday night ... An upper level
ridge of high pressure will maintain its position over the western
atlantic through the short term period, while an upper level low
and associated inverted trough axis propagates westward across the
gulf of mexico. A surface ridge of high pressure will also
generally extend from the mid-atlantic states through the
southeastern states during this time frame. Our forecast area
generally remains on the western fringe of the ridge axis and to
the north of the trough over the gulf of mexico through the
weekend. A slightly drier airmass will be in place on Saturday, so
there may be a little less in the way of convective coverage
across our region. We will maintain 20-40% pops during the day
Saturday, with the more scattered coverage focused along southern
portions of the area along the vicinity of the seabreeze. Deep
layer moisture improves slightly on Sunday, and will keep
scattered showers and storms in the forecast across the entire
area. Little change in the overall temperature forecast, with
highs around 90 to the lower 90s inland, and upper 80s along the
coast. 21
long term Monday through Thursday ... An amplified pattern
will take shape through much of next week as a broad upper level
trough deepens over the central and northern u.S., while the ridge
of high pressure continues to build from the western atlantic
through the gulf of mexico. Deeper moisture within increasing
southerly to southwesterly flow aloft will spread across much of
the forecast area next week, and a more unsettled weather pattern
with increased (50-60%) chances of showers and thunderstorms are
expected each day Monday through Thursday. Current indications are
that above normal temperatures persist into next week, though
highs may fall back down into the mid to upper 80s with increased
cloud cover and precipitation chances. 21
marine... Surface high pressure holds over the southeast into the
weekend and slowly builds from the northeast by early next week.

Storms look to become more scattered in coverage into the weekend
and perhaps numerous at times by Monday on the southwest periphery
of the surface high. Main hazards in storms for recreational and
commercial boaters will be brief strong wind gusts, frequent
lightning activity and locally higher waves and seas. Away from
storms, a gradual build in seas is anticipated by early next week
due to a persistent southeast fetch. 10
