06z issuance...VFR conditions expected into the overnight hours
under light to near calm southerly winds. Local drops in visbys
to MVFR levels are possible towards sunrise in patchy fog, but
coverage is expected to be limited.

After sunrise Thursday, local MVFR level CIGS are likely in the
morning as CU develop, but by noontime, CIGS are expected to be at
vfr levels. A small chance of afternoon thunderstorm development
Thursday can bring localized MVFR level CIGS visbys in heavy rain,
but coverage is expected to be isolated at most and of little to
no impact to operations. A light south wind in the morning will
rise to around 10 knots with the day's heating, a bit higher along
the coast.

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

Update... Aside from a few tweaks to the forecast to account for
current trends, the forecast remains generally on track. Isolated
storms over southern covington which formed this evening along the
sea breeze front should dissipate in the next couple of hours as
the airmass becomes increasingly stable. 08

00z issuance...VFR CIGS and visbys expected into the overnight
hours, with south to southwest winds around 10 knots becoming
light to around 5 knots. Patchy light fog is possible beginning
closer to sunrise Thursday, with visbys remaining generally at or
above 4sm.

MVFR CIGS are possible in the morning as morning CU develop, but
generalVFR conditions are expected by noontime. Light and
variable winds in the morning will become a more organized
southerly by early afternoon, with 5 to 10 knots expected inland,
around 10 knots closer to the coast.

near term now through Thursday ... An upper high pressure area
over the southern plains, northern gulf and far southeast conus
will shift slightly westward and build northward as an upper
trough over the eastern CONUS reaches the atlantic seaboard. A
surface high pressure ridge extending from the western atlantic,
across the florida peninsula and the gulf of mexico deep south,
will keep a light southerly wind flow over the forecast area. This
flow off the gulf will hold dewpoints in the low to mid 70s. The
combination of low level moisture in place and mostly clear to
partly cloudy skies, should result in patchy fog late tonight into
Thursday morning. Dry conditions area-wide will persist through
noon Thursday, followed by isolated showers and thunderstorms
north of i-10 during maximum heating hours.

Low temperatures tonight will be 1 to 3 degrees above normal,
ranging from 71 to 74 degrees inland areas, with mid to upper 70s
along the coast. High temperatures Thursday will be 2 to 4 degrees
above normal, ranging from 93 to 98 degrees inland areas, with upper
80s to lower 90s along the coast. Heat indices Thursday will reach
100 to 105 degrees. 22
short term Thursday night through Saturday night ... A broad
upper ridge will be in place across most of the southern portion
of the CONUS and into the western atlantic through the period. An
exception to this larger scale pattern is a weak upper trof
located initially from the mid atlantic coast into the extreme
southeast states which drifts slowly westward across the central
gulf coast region through Saturday night. This feature will result
in a more convectively favorable environment over the forecast
area than would otherwise be in place. A surface trof associated
with the upper trof will be located along the east coast states
Thursday evening and into georgia. As the upper trof moves slowly
westward, the surface trof extends weakly westward into the
interior portion of the forecast area on Friday while a surface
ridge remains over the northern gulf and promotes a light
southerly flow. Some vestiges of the surface trof look to linger
over the area on Saturday as well.

Mlcape values increase to around 1500 j kg each day, while shear
values remain very low (0-6 km bulk shear 5-15 knots).

Precipitable water values will be near 2 inches along with wet
bulb zero values of 13-14 kft. With this environment, expect
scattered to numerous showers and storms to develop on Friday and
Saturday as well as the surface trof (or vestiges of) aids in
initiating convection. The storms will move slowly in this weakly
sheared environment, and given the elevated precipitable water
values, this may lead to some nuisance flooding. The rip current
risk is expected to be low through the period. Highs will be 90 to
95 on Friday then mainly in the lower 90s on Saturday. Heat index
values of 103 to 108 are expected on Friday, possibly reaching
heat advisory criteria in a few spots, then lower values follow
for Saturday due to the somewhat cooler daytime highs. Lows
Thursday night range from the mid 70s inland to the upper 70s near
the coast then trend a bit cooler by Saturday night to range from
the lower 70s inland to the mid 70s near the coast. 29
long term Sunday through Wednesday ... The weak upper trof will
be centered over louisiana and the northwestern gulf Sunday
morning then is expected to continue westward further away from
the area and eventually dissipate. A larger upper trof advances
southward across the great lakes region on Monday and amplifies
over the eastern states through Wednesday. An associated surface
low well to the north brings a cold front southward into
arkansas tennessee by Monday morning which then weakens into a
surface trof while continuing slowly into the forecast area on
Tuesday. Some vestiges of the weak surface trof manage to persist
over interior portions of the area on Sunday so have gone with
good chance to likely pops, then chance to good chance pops follow
for Monday. Expect sufficient coverage on Tuesday to support
likely pops as the surface trof moves into the area, then good
chance pops follow for Wednesday. Highs Sunday and Monday will
generally be in the lower 90s then moderate during the remainder
of the period with highs on Wednesday mainly in the upper 80s. Lows
range from the lower 70s inland to the mid 70s at the coast. 29
marine... High pressure will remain over the eastern and northern
gulf of mexico, keeping a light southwesterly wind flow through
Monday. The highest winds and seas will occur over the near shore
waters out to 20 nm, including inland bays and sounds, during the
afternoon and early evening hours due to afternoon heating inland.

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.
