Synopsis..A light to moderate northeasterly flow will prevail over the marine area today. North to northeast flow will strengthen tonight through Wednesday night as a weak area of low pressure moves toward the eastern gulf of mexico and as a reinforcing cold front pushes across the marine area.

12z issuance...VFR conditions are expected through the next 24
hours underneath scattered to broken mainly mid and high level
cloud decks. Some lowerVFR decks between 3-5 kft agl possible
this morning over far eastern portions of south central al and the
northwest fl panhandle. Near calm to light E NE winds prevail this
morning, with calm to light northerly winds this afternoon into
this evening. 21
prev discussion... Issued 454 am cst Tue nov 21 2017
near term now through Tuesday night ... A shortwave trough axis
extends across the lower mississippi valley and adjacent western
gulf of mexico early this morning, while surface high pressure
continues to ridge westward from the carolinas through the gulf
coast region. Satellite imagery shows abundant high level cloud
cover streaming over our forecast area in the southwest flow aloft
ahead of the trough axis, but dry and chilly conditions otherwise
prevail early this morning, with temperatures ranging in the 30s
over interior northwestern portions of the forecast area, and in the
lower to mid 40s near the coast.

The southern stream shortwave trough will eventually phase with
another trough diving from the plains states toward the mississippi
valley region today, before the trough axis gradually approaches the
gulf coast states late tonight into early Wednesday morning. An
associated reinforcing cold front will move southeast toward the mid-
mississippi valley region by late this afternoon before quickly
continuing its southeastward push across the central gulf coast
region and adjacent northern gulf of mexico late tonight into early
Wednesday morning. The latest blend of short range model guidance as
well as high resolution guidance indicates that moisture will be
very limited across most of our area today and tonight. The
exception could be the far eastern fringe of the forecast area where
the western extent of low level warm advection isentropic ascent
could aid in the development of a few light rain showers. We will
keep a 20% chance of rain in the forecast generally east of a
luverne, al to destin, fl line through this afternoon. We otherwise
expect highs today to range in the upper 60s to around 70 across
much of the region.

Isentropic ascent over the eastern portion of our area gradually
weakens and shifts east this evening. Meanwhile, other deeper
moisture and lift associated with the aforementioned upper level
trough axis looks to remain confined well to our west and southwest
over southern portions of louisiana tonight. With little in the way
of moisture available across our area ahead of the advancing cold
front, we will keep a dry forecast intact tonight. Another cool
night is anticipated with lows ranging around 40 to the mid 40s
inland, and in the upper 40s to mid 50s closer to the coast and the
beaches. 21
short term Wednesday through Thursday night ... Shortwave energy
continues to move into and deepen an upper trough over the
eastern conus. Energy in the base of the trough (and over the gulf
of mexico) maintains and shifts SE east a surface trough
stretching sw-ne across the gulf, keeping the forecast area under
general northerly flow. This northerly flow will move in cooler,
drier air. Some shra are possible north of the central gulf trough
wed Wed night, mainly eastern parts of the western florida
panhandle, but by Thursday, am expecting this to shift SE with the
cooler drier re-enforcement.

Temps for this portion of the forecast maintain an around to bit
below seasonal daytime temps ranging from low 60s northwest to mid
60s southeast. Overnight lows see the greatest gradient for this
period, randing from mid 30s northwest to mid 40s southeast.

long term Friday through Monday ... The upper trough is
maintained over the eastern CONUS through the weekend, with an
eastward shift Sunday night through Monday as upper energy moves
over the northwestern quarter of the conus. This pushes eastward
an upper trough that has been maintained over the us southern
canadian rockies, but at this point, any subsidence from the ridge
doesn't affect the forecast area until after the current package.

Temps moderate upward Friday into Saturday, but another shortwave
system moving into this trough brings back cooler temps. The
ecmwf is advertising a cooler solution than the gfs, but with the
gfs and ECMWF ensemble advertising an in-between solution, have
went that direction for the forecast. Highs Friday and Saturday
range from the mid 60s to around 70, then drop to the low to mid
60s Sunday, upper 50s to low 60s for Monday. Lows Friday and
Saturday night see low 40s north to upper 40s close to the coast.

Sunday night sees the effects of the cooler re-enforcement, with
lows ranging from mid 30s north to around 40 close to the coast.

Marine... Surface ridging will weaken over the marine area today,
with a prevalent light to occasionally moderate northeasterly flow
expected through this afternoon. A reinforcing cold front is
expected to push across the marine area after midnight tonight and
into the early morning hours Wednesday. Expect northerly flow to
strengthen to cautionary levels over most bays and sounds late
tonight into Wednesday morning, and to small craft advisory
thresholds over the al northwest fl coastal waters out 60 nm. Wind
speeds may abate just a bit Wednesday afternoon, but will strengthen
again Wednesday evening into late Wednesday night. We have issued a
small craft advisory for the offshore waters out 60 nm from late
tonight through late Wednesday night as northerly winds average
around 20 knots with occasional higher gusts through much of this
period. A moderate northerly flow will continue Thursday into Friday
as high pressure builds southeastward toward the gulf. Winds may
transition more northwesterly to westerly Saturday before the next
cold front potentially brings stronger northerly flow late Saturday
night into Sunday. 21

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.
