National Weather Service Shreveport LA
1104 PM CDT Tue Sep 19 2017

.AVIATION...
Only change with the 06z TAF package was to step the potential for
dense fog back at the MLU/LFK terminals and this is due to the
extensive debris blowoff in the form of high clouds from weakening
convection across the TX Hill Country late this evening. That and
spreads of 2-3 degrees exist at these locations where fog was
beginning or had already begun to form at this time 24 hours ago.

The blowoff will should not hamper the return of IFR/LIFR ceilings
however and these ceilings should be moving northward or
developing northward towards the I-20 terminal locations overnight
tonight through sunrise Wed morning. These ceilings will quickly
become VFR or scatter out all together by late morning into the
afternoon hours on Wed.

Widely scattered convection will be possible on Wed during the
afternoon hours, mainly at the LFK and MLU terminals but left this
mention out of the 06z package as coverage does not warrant a
mention attm.

DISCUSSION...
For this update have removed the mention of rainfall and adjusted
the cloud cover up with the current trend of low level moisture
feeding into Central and North Texas and approach of short wave
trough of low pressure across South Oklahoma and North and Central
Texas, and along the Western side of weak upper level ridge
over Southeast Texas and Southwest and East Texas. Also tweaked
the temperatures and dew points that may not affect the wording in
the zones. /06/
