prev discussion... Issued 449 am cdt Sun sep 23 2018
near term now through Sunday night ... Shortwave energy moving
through a shallow upper trough over the mississippi river valley
and a weakening upper system moving west over the central gulf
will bring a bit wetter period to the area into tonight. Also
helping with the bump up in rain chances is a surface ridge
stretching south along the appalachians and southeasterly flow on
the western edge of an upper ridge stretching west over the
southeast bringing an increase in deep layer moisture off the gulf
(precip h20 values rise into the 1.8-2.0" range). The best
combination of upper level dynamics and convection initiation from
an inland moving seabreeze off the gulf will be along the coast,
so have placed higher pops there, dropping off as one moves
inland. Looking at temps, with subsidence from the upper ridge
over the southeast continuing over the forecast area being
counter-balanced somewhat by an increase in cloud cover from
today's convection, am expecting highs today to continue to rise
to above seasonal levels (upper 0s to around 90), but cooler than
yesterday. 16
short term Monday through Tuesday night ... The east-west
orientated upper level ridge over the northern gulf of mexico and
deep south will persist through Tuesday afternoon as a large upper
trough digs south over the nation's mid-section. This ridge will
then shift slightly southeastward Tuesday night as the base of the
upper trough reaches arkansas and northern mississippi. The
surface ridge of high pressure across the southeast states and
eastern gulf of mexico will persist through the short term,
maintaining a light, moist southerly surface wind across the
forecast area. Meanwhile, a surface cold front associated with
the upper trough will advance southeast across the great plains
before reaching southern arkansas and western tennessee by late
Tuesday night.

Shower and thunderstorm activity will increase in the short term,
with mainly numerous showers and thunderstorms forecast during
the day both Monday and Tuesday. Isolated to scattered coverage of
showers and thunderstorms are forecast during the overnight
hours, but pockets of numerous showers and thunderstorms could
occur after midnight Monday night along coastal alabama, and after
midnight Tuesday night across the western third of the forecast
area as the upper trough approaches. Additional widespread
rainfall amounts through the short term are expected to range from
0.6 to 0.9 inches inland areas, and around an inch across the
coastal sections. Isolated amounts up to 2 inches are possible.

Slightly above normal temperatures will persist through the short
term. 22
long term Wednesday through Saturday ... The upper level ridge of
high pressure over the extreme southeast CONUS and eastern gulf will
persist through noon Friday as the broad upper trough remains to
our north. This ridge will then expand westward and northward
Friday afternoon through Saturday night as the upper trough
weakens. The surface ridge across the southeast states and
northeast gulf will weaken, but a warm and moist environment with
a light southerly surface wind flow will remain. The surface ridge
will then build across the region the latter half of the week. An
unsettled weather pattern will remain in place, with a 60-80%
chance of showers and thunderstorms each day Wednesday and
Thursday, followed by a gradual decrease in rain chances Friday
and Saturday. Slightly above normal temperatures will persist
through the long term. 22
marine... A surface ridge stretching southwest along the
appalachians will bring a continued light to at times moderate
southeast to south flow through the forecast. Scattered to
numerous showers and thunderstorms are expected through the
forecast, with little change in seas. 16

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.
