.UPDATE...
Convection for the evening has pretty much dissipated across our
eastern most zones attm. For that reason, have removed mention of
pops for the remainder of the overnight hours. Hourly temperatures
for the 9 pm hour are running near to slightly above those from
yesterday attm and for that reason, did bump up overnight low
temps in a few locations but not by much. Given daytime highs
today in the middle to upper 90s across all our region, made some
changes to daytime highs for Sunday, bumping them up a a degree or
two, especially across our eastern most zones. Also given Heat
Index temperatures today and with similar conditions expected on
Sunday, added a few counties in Northeast Texas to the ongoing
Heat Advisory which is valid through 7pm Sunday Evening.

Otherwise, no additional changes were necessary this evening.
Updated zone package and NPW concerning the changes with the Heat
Advisory coming out shortly...13.

.PREV DISCUSSION... /issued 658 PM CDT Sat Aug 19 2017/

AVIATION...
For the 20/00Z TAF period, VFR conditions will prevail throughout
the period. Ongoing isolated convection should begin winding down
after sunset with heating loss as SHV/MLU/LFK will maintain VCTS
for the first few hours of the period. Otherwise, expect light and
variable winds this evening through overnight, increasing slightly
out of the SE after sunrise Sunday. Cu field will redevelop toward
afternoon with isolated convection possible once again but lacking
confidence will preclude mentioning in this TAF cycle.
