Area Forecast Discussion...UPDATED
National Weather Service Shreveport LA
1159 PM CDT Wed Jul 26 2017

.AVIATION...
VFR conditions will continue through much of the 27/06Z TAF
period. Still seeing an extensive area of cirrus spilling SW into
the region early this morning, with additional cirrus expected to
spill SSW overnight in response to convection developing over NE
OK/SE KS into much of MO and spread slowly SE through daybreak
before weakening by mid-morning. Can`t rule out isolated areas of
patchy FG/IFR/low MVFR cigs affecting portions of Deep E TX
(including LFK) and Wcntrl LA around/shortly after 12Z, but
believe that it will not be as widespread as what was observed
this morning and should lift by 14-15Z. Otherwise, a sct cu field
will develop again by 15-16Z areawide, before diminishing shortly
after 00Z Friday. The convection well to our N tonight should
leave behind residual convective bndrys across portions of Ern
OK/Nrn and Cntrl AR, which could fire off sct convection Thursday
afternoon, in addition to other convection near a weak sfc front
over Srn KS/MO. Thus, convective debris should begin to spill S
into the region by the end of the TAF period, with the potential
for at least isolated to sct convection developing/affecting
portions of SW AR (including the TXK and ELD terminals) between
06-12Z Friday. S winds 3-7kts tonight will become SSW 6-11kts
after 15Z. /15/

.PREV DISCUSSION... /issued 950 PM CDT Wed Jul 26 2017/

DISCUSSION...
Isolated convection that developed across the Toledo Bend Country
of Deep East Texas and Western Louisiana during the late afternoon
finally dissipated within the last hour. The remainder of the
nighttime hours should be precip free. Thick cirrus is moving
southward from the plains into the area, so most of the CWA north
of Interstate 20 will experience increasing cloud cover tonight.
Sky grids were updated to reflect these trends. Otherwise, no
major updates are anticipated this evening.
