Area Forecast Discussion...UPDATED
National Weather Service Shreveport LA
1200 AM CDT Sun Jul 22 2018

.AVIATION...
VFR conditions will continue through the 22/06Z TAF period. AC
cigs have begun to develop over portions of Scntrl AR/NE LA, and
may briefly affect the ELD/MLU terminals overnight before shifting
S across Ncntrl LA by/ daybreak Sunday. Some sct low stratus may
also develop over SE TX by/shortly after 12Z and spread across
portions of Deep E TX/Cntrl LA, but not expecting any IFR/low MVFR cigs
at LFK before the stratus quickly lifts/dissipates by mid-
morning. Otherwise, areas of AC/cirrus cigs will drop SSE across
the region from the NNW by early to mid-afternoon, affecting much
of the region late in the day. These cigs should linger through
the remainder of the TAF period. WSW winds 4-8kts tonight will
become WNW 5-8kts after 15Z Sunday, but more VRB across SW AR as a
weak sfc front lingers/drifts slowly S into extreme NE TX to
along or just S of the AR/LA border. /15/

SHORT TERM.../Tonight/
Despite the thin cirrus shield having cleared the region to our
SSW this evening, 02-03Z temps still remain in the mid 80s to in
excess of 90 degrees, with the hotter readings over the urban heat
islands of TYR/GGG/SHV/TXK. With WSW winds expected to stay up a
tad overnight, the air will remain well enough mixed such that
much of the region will not fall much below 80 degrees Sunday
morning (if at all), the exception being across the more protected
and rural locales.

The short term progs have backed off on the extent of AC
development tonight, although some may still develop mainly over
portions of Scntrl AR/Ncntrl LA late. Have toned down the sky
grids to reflect mostly clear conditions tonight through much of
Sunday morning, although the AC/cirrus cigs should spill SSE into
the region from the NNW especially for the afternoon. Otherwise,
the weak sfc front, analyzed from along the Red River of Srn OK
extending ENE across Cntrl/Nrn McCurtain County OK, and into
Wrn and Cntrl AR, still remains progged to drift S overnight into
SW AR to along the AR/LA border by daybreak Sunday, allowing drier
air to begin seeping across the Nrn zones late tonight through
much of Sunday. Thus, the current Heat Advisory still looks good,
especially as the elevated cigs increase Sunday afternoon over SW
AR and eventually over N LA resulting in slightly cooler max temps.

Zone update already out...grids will be available shortly.

AVIATION...
VFR conditions will continue through the 22/00Z TAF period. While
the thin cirrus will continue to diminish this evening across Deep
E TX, areas of AC look to linger (redevelop) tonight over SW AR/N LA.
Should start to see additional AC and cirrus cigs develop by late
morning Sunday through the afternoon from the NW and spread SE
across much of the region. WSW winds 4-8kts tonight will become
WNW 5-8kts after 15Z Sunday, but more VRB across SW AR as a weak
sfc front lingers/drifts slowly S into extreme NE TX to along or
just S of the AR/LA border. /15/
