.AVIATION...
Cu field should continue expanding to encompass all terminal
locations later today but convection if any should be isolated and
therefore will warrant no mention in the terminal package. Cu
field will dissipate by early evening with only thin cirrus
expected to increase from the south overnight.

Model cross sections do not support the development of
VLIFR/LIFR/IFR ceilings overnight towards sunrise this morning but
for this TAF package...went with persistence which suggest the
possibility of these ceilings across our NE TX terminal locations
in the 08-14z timeframe. Also stuck with persistence concerning
vsbys with at least mvfr vsbys across a few terminals early Thu
morning with the possibility of 1/4SM at the LFK terminal in the
08-12z timeframe.

Otherwise...expect any low ceilings after sunrise on Thu to
quickly scatter our with broken high ceilings areawide.

.PREV DISCUSSION... /issued 1048 AM CDT WED AUG 24 2016/

DISCUSSION...
Fog has lifted, but low clouds have been somewhat slow to
scatter across East Texas south of Interstate 20. Elsewhere,
mostly clear skies and abundant sunshine have allowed
temperatures to rapidly warm into the mid to upper 80s,
especially across Northern Louisiana. High temperatures for today
were raised a couple of degrees, especially across the eastern
half of the forecast area. Model guidance continues to mix
dewpoints out too much, so dewpoint were also raised. These edits
did not warrant any modifications to the Heat Advisory.

Updated text products have been sent.
