GMZ600 Synopsis For Pascagoula Ms To Okaloosa Walton County Line Fl Out 60 Nm Including Major Area Bays And Sounds- 340 Pm Cdt Sun Sep 15 2019
Synopsis..A broad surface ridge of high pressure over much of the deep south will continue to extend southward over the northern gulf through midweek, then build further south later in the week. A light to moderate easterly wind flow will continue over the marine area through early next week followed by a more westerly flow through midweek. A moderate to occasionally strong easterly wind flow will redevelop late in the week as a strong surface ridge of high pressure builds along the eastern seaboard.

Discussion Updated for latest aviation discussion below.

Aviation
00z issuance... Broken to overcast mainly high based clouds
to continue over the TAF sites, north of an upper level low over
the gulf. A generally light northeast wind flow overnight. 10

Prev discussion issued 354 pm cdt Sun sep 15 2019
near term now through Monday ... A broad upper ridge of high
pressure stretching from the central plains states to the eastern
seaboard and south to the northern gulf coast will weaken slightly
to the south and shift slightly east through Mon afternoon as a
weak mid to upper low pressure system over the western gulf
continues to track west and deepen. Near the sfc a broad ridge of
high pressure continues over much of the eastern CONUS combined
with TS humberto moving north off the east fl coast leading to a
better pressure gradient continuing along the northern gulf coast
today through Mon afternoon. As a result slightly better surface
winds generally from the east will continue mostly over the lower
half of the forecast area through Mon afternoon with the better
wind velocities over land occurring mostly during the daylight
hours. Better moisture in the boundary layer mostly in the form of
mid to high clouds from the east will continue to advect west and
south as humberto continues to track north. Also noted near the
coast and offshore weak forcing in the mid levels combined with
sufficient moisture and instability will continue through early
mon as the area of low pressure over the western gulf continues to
shift west. As a result similiar to this morning showers and
thunderstorms will begin to move into lower parts of the marine
area this evening and shift north to the immediate coast by
sunrise Mon possibly moving over southern parts of mobile and
baldwin counties in al early in the day.

Temperatures will continue to be well above seasonal norms tonight
and on mon. Lows tonight will range from the lower to middle 70s
inland and the mid to upper 70s along the immediate coast. Highs mon
will range from middle 90s for most inland areas and the lower to
middle 90s along the immediate coast. 32 ee
short term Monday night through Wednesday night ... A longwave
upper ridge dominates much of the eastern and south central states
through the period. A light northerly surface flow continues over
the area through Wednesday, then a strengthening surface ridge
over the eastern states pushes a back-door cold front into the
area Wednesday night. Subsidence associated with the upper ridge
will result in dry conditions through Wednesday. Despite the back
door front moving into the area Wednesday night, model soundings
still look too dry to support precipitation. The subsidence will
contribute to hot conditions each day, with highs mostly in the
upper 90s. Cooler air will begin to flow into the area in the wake
of the back door front, but this will be delayed until the long
term period, so lows each night range from around 70 well inland
to the mid 70s at the coast. A low risk of rip currents is
expected through the period. 29
long term Thursday through Sunday ... Improved moisture seen
mainly from 800-700 mb along with layer lifting near 300k looks
sufficient to support isolated to possibly scattered convective
convective development for much of the area on Thursday as the
back door front moves through the remainder of the area. A surface
ridge remains in place over the southeast states through Saturday
then retreats a bit into the western atlantic on Sunday as a
surface low well to the north brings a weak trailing cold front
across the mid mississippi river valley. Expect dry conditions to
prevail over the area Friday through Sunday, although some
isolated convection will be possible near the coast on Sunday as a
return flow attempts to develop. Highs will be "cooler" in the
wake of the back-door front but still several degrees above
normal, with mainly lower 90s expected each day. Overnight lows
will typically range from the mid 60s well inland to the lower 70s
near the coast. 29
marine... A broad surface ridge of high pressure over much of the
deep south will continue to extend southward over the northern gulf
through midweek, then build further south later in the week. A light
to moderate easterly wind flow will continue over the marine area
through early next week followed by a more westerly flow through
midweek. A moderate to occasionally strong easterly wind flow will
redevelop late in the week as a strong surface ridge of high
pressure builds along the eastern seaboard. 32 ee

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
