Area Forecast Discussion
National Weather Service Shreveport LA
616 PM CDT Wed Jul 19 2017
.AVIATION...
For the 20/00z Tafs...VFR conditions to prevail throughout most of
the TAF period, as an upper level ridge of high pressure remains
in control of our weather pattern. A few shwrs/tstms will be
possible across the Taf sites this evening, but will be too isold
to mention in TAFs attm, so will amend as necessary. Most of the
convection should begin to diminish just after sunset. Otherwise,
light and generally vrbl winds to continue through the period.

.PREV DISCUSSION... /issued 136 PM CDT Wed Jul 19 2017/
DISCUSSION...
An upper ridge of 597 dkm at 500 HPa centered over SRN KS this
Wednesday afternoon to weaken slightly and progress E into the SE
U.S. through this weekend. Underneath this ridge on the S flank,
expect a weak short wave trough to retrograde W across the Gulf Coast
during this upcoming weekend. This trough will reignite the
seabreeze and result in SCT showers and TSTMS during this weekend,
a development always welcomed during this time of year. We can expect
typical summertime daylight convection this weekend as TSTMS develop,
dissipate, and produce outflow boundaries that often collide with new
TSTMS then developing in these boundary interactions.
This trough should weaken and move W into TX next week. Weak NW flow
then becomes established across the ArkLaTex and NE LA during next
week with perhaps some nighttime TSTMS possible. In any case, temps
cool to near 90 degrees for highs, also a welcome development as
well as we reach the peak of summer with climatological highs in the
mid 90s and lows in the mid 70s. /VIII/.
