Area Forecast Discussion
National Weather Service Shreveport LA
540 PM CDT Tue Sep 19 2017

.AVIATION...
Showers dissipating much more quickly this evening compared to 24
hours ago and for that reason, we will be leaving any mention of
them out of the 00z package. Otherwise, expect cu field to
continue diminishing in coverage throughout the remainder of the
evening hours. Low level pressure gradient remains strong enough
that we should see stratus returning overnight across most
terminal locations with the possibility of LIFR ceilings at all
terminal locations except the ELD/TXK terminals. Our Arkansas
terminals could see MVFR ceilings after sunrise Wed morning. Also
a possibility will be a reduction in visibility with dense fog
likely at the MLU and LFK terminals. Elsewhere, 3-5SM vsbys will
be a concern after midnight and through the 13-15z hour.

Winds will be light south to southeast overnight, except at our
NE TX terminals where speeds at the TYR/GGG terminals could be in
the 6-10kt range. Stronger wind speeds will remain across these
terminal locations during the daytime hours on Wed while speeds
settle in between 6-10kts at our remaining terminal locations.

.PREV DISCUSSION... /issued 307 PM CDT Tue Sep 19 2017/

DISCUSSION...
Static pattern to continue as long wave troughing to the west
deepening and entrenching upper ridge over our area, stretching
towards the Ohio River Valley. Afternoon highs either side of 90
degrees and heat index readings either side of 100 degrees to
continue with overnight lows in the lower to mid 70s. Fog
development overnight to likely also continue, especially around
the East TX Lakes. Mrng low clouds to scatter out as sea breeze
convection brings isold to possible sct diurnal development across
mainly southern portions of the area. By the end of the fcst
cycle, stg but stnry cold front will still likely be poised to our
west, ready for enough change in the pattern to start making
headway towards the area, or at least get close enough to begin
improving tstm chances to western portions of cwa by the middle of
next week.
