Aviation
For the 25 12z tafs, MVFR ifr flight conditions will prevail
initially at most terminals in louisiana and east texas as low
clouds and patchy fog have once again developed and spread
northward across the region. The fog should dissipate within the
first couple of hours of the TAF period. Ceilings will also
gradually improve, but somewhat slower. However,VFR conditions
should prevail areawide by 25 16z-25 17z. Another round of
MVFR ifr ceilings and visibilities are expected in most locations
near the end of this TAF cycle.

short term... Today through Sunday
an upper level ridge will remain firmly entrenched over the
southeast CONUS through Sunday. Subsidence associated with this
ridge will continue to keep hot and generally dry conditions in
place. Any convection that develops over the plains along a
dryline and quasi-stationary front will stay well west and north
of the forecast area. Similar to yesterday, one or two very
isolated showers cannot be ruled our during peak daytime heating
this afternoon, but overall rain chances are very low. Chances for
isolated convection should be even lower on Sunday as the upper
ridge elongates westward over more of the region. Otherwise, a
persistence forecast continues to be the rule of thumb. Daytime
high temperatures will once again warm into the upper 80s to lower
90s. As humidity levels continue to climb, heat index values will
likely rise into the mid to upper 90s over much of northern
louisiana.

Cn
long term... Sunday night through Friday night
surface and upper-level ridge to prevail from Sunday night through
Tuesday, maintaining dry conditions across the region. Temperatures
to range from lows in the lower 70s to highs in the upper 80s to
lower 90s each day.

Temperatures to trend slightly cooler from Tuesday night onward as
upper-level ridge shifts east and a cold front approaches the region
from the northwest. Frontal boundary to serve as the focus for
daytime showers and thunderstorms each day through Friday. Models
still struggling to come to a consensus on whether the front will
actually make it into the ARKLATEX or stay just to the north. Based
on previous model runs, favored a cooler solution with front
bisecting the region by Thursday night. This will allow for cooler
temps across the i-30 corridor with highs in the lower 80s and lows
in the lower 60s. Areas south of the front will remain in southerly
flow with highs climbing to the upper 80s and lows in the lower 70s.

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.
