.AVIATION...
VFR conditions will continue through the 23/00Z TAF period.
Extensive areas of AC cigs will continue to spill S across the
remainder of E TX/Lower Toledo Bend Country this evening, and
persist overnight through much of Monday morning. Within these AC
cigs, areas of -RA/sprinkles will be possible tonight through
Monday morning, but given the very dry low level air mass in 
place, not expecting cigs to lower much nor vsbys to be reduced. 
Should start to see the AC scatter out over SW AR late Monday 
morning/midday, and across portions of N LA by early to mid 
afternoon, although a sct cu field will develop/advect SSW across 
much of SW AR/Ncntrl LA during the afternoon behind a weak sfc 
front that will slowly backdoor SW into Lower E TX/Cntrl LA during
the afternoon. Lt/Vrb winds tonight over SW AR/extreme Nrn LA/NE
TX, and light SW winds over Deep E TX/Ncntrl LA, will become NNE
5-8kts over much of the region after 15Z Monday, although Deep E
TX will remain WSW through much of the day ahead of the weak sfc
front. /15/
