Aviation
Vfr conditions will prevail across the terminals through the
majority of the TAF period. Clearing skies can be expected
overnight with MVFR fog anticipated near dawn at kggg, kshv, and
kulm. Highest confidence in fog developing is at kggg where
heaviest rainfall occurred earlier in the evening. Kshv also had
rainfall this evening and kulm MVFR fog is predicted based off
persistence from Wednesday morning.

Based off latest hrrr trends, shower and thunderstorm coverage is
anticipated to be more isolated Thursday afternoon. Thus, held off
on vcts and CB in the tafs with just diurnally driven scattered
clouds for this issuance. As confidence builds in future high
resolution model runs, CB vcts may be needed for some of the
terminals. 04

update...

the latest mid-level analysis indicates a 500mb ridge extending
from the northern gulf of mexico into the tennessee valley. This
broad feature will continue to be the predominant feature across
the four state region as it edges eastward overnight. In this
pattern, lingering showers in deep east texas will diminish as
instability decreases. Cloud coverage in deep east texas will
decrease as it moves northwestward toward the red river in texas.

The biggest change with this evening's update was to cool
temperatures where showers and thunderstorms lingered in deep east
texas this evening and to account for increased cloud coverage
early on in these areas. 04
short term... Tonight through Thursday night.

Isolated showers and thunderstorms have developed again across the
region this afternoon, but most of this activity will diminish
after sunset. With the upper ridge still in place across the
region today, temperatures have once again topped out in the mid
to upper 90s. However, the upper level ridge will begin to slowly
shift eastward tomorrow. This will allow for a nice return of
moisture flow from the gulf of mexico to make it back into the
area over the next couple of days. With a nice return flow and
daytime heating, another chance of diurnal showers t-storms will
develop across the region again tomorrow afternoon, but still
expecting coverage to be isolated to widely scattered.

Temperatures will remain hot and humid across the region on
Thursday with high temperatures in the mid to upper 90s and lows
in the mid 70s. 20
long term... Friday through Wednesday
beneficial cooling rainfall for this weekend and next week...

expect the 592 dekameter ridge at 500 hpa that has been dominating
our weather the past several days to progress eastward into the
atlantic ocean off the SE u.S. Coast through this weekend and most
of next week. As a result, a quasi stationary trough will develop
in the wake of this ridge across the southern plains. In addition,
expect advected moisture from the remnants of last week's tropical
system named issac to produce sct to numerous showers and tstms
during Friday and through this weekend.

For next week, expect sct showers and tstms to continue in the
forecast as a favorable moisture advection pattern continues from
the gulf. Also, we may receive moisture advection as well from the
ern pacific as typical, seasonally, disturbed tropical weather
continues off the W coast of mexico.

We should receive near one inch of rainfall areawide during the next
seven days with a few areas across the ouachita and kiamichi
mountains perhaps tallying upwards of three inches. These
beneficial rains will alleviate our current dry antecedent soil
moisture conditions. Viii .

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.
