Areas of ifr low MVFR CIGS have developed advected NE across much
of E tx N la this morning, and may affect portions of SW ar by
mid-morning before a gradually improvement is observed. However,
MVFR CIGS may linger through much of the morning before becoming
vfr, with the CU field scattering out by early to mid afternoon. A
weak shortwave noted over ecntrl tx will shift E across the region
today, resulting in areas of ac cirrus CIGS which will gradually
diminish from W to E this afternoon, with only isolated convection
possible this afternoon over portions of E tx N la. However, low
confidence precludes vcsh mention in the taf's attm. The CU field
should diminish by early evening, with skc returning to all but
portions of scntrl ar ERN sections of ncntrl la where some
ac cirrus may linger. However, additional low MVFR and possibly
ifr CIGS will redevelop across E tx WRN la after 06z Thursday,
possibly affecting the tyr ggg lfk shv terminals by the end of the
taf period. Ssw winds 6-12kts with occasional gusts to 20kts over
portions of NE tx today, will diminish to 3-8kts after 00z, with
the weaker winds over ncntrl la scntrl ar. 15

some patchy fog and low stratus will once again be possible this
morning, mainly south of interstate 20. However, abundant mid and
high level convective debris cover the area, which should limit
the fog potential for most locations. Any fog that does develop,
should dissipate by mid morning. Otherwise, similar conditions are
expected as the last couple of days. Daytime temperatures should
warm into the low to mid 90s. Surface dewpoints should also be
in the 70s as low-level southerly flow draws gulf moisture
northward. This combination will likely result in heat index
values above 100 degrees f across most of the area this afternoon.

A heat advisory is not anticipated at this time. The sea breeze
may also bring isolated to widely scattered diurnal convection to
areas south of interstate 20 this afternoon and into early this
evening.

A general persistence forecast will be the rule through at least
Sunday. An upper ridge axis over the area will amplify through the
weekend keeping warm and mostly dry conditions in place. Diurnal
sea breeze activity will continue to be the main source for rain.

During the weekend, a weak upper low will drift west across the
southeast CONUS and towards the region. Vertical ascent may be
slightly enhanced by this features, which may provide some
increase in convective coverage during the weekend, mainly across
southern arkansas and louisiana.

Medium range models continue to suggest a pattern shift will be
coming early next week as a longwave trough digs across the
western u.S. And then moves across the northern plains during the
middle of next week. The passage of this trough axis should help
to push a cold front into the region next week. This front should
provide a much better chance at widespread and organized
convection.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
