Area Forecast Discussion...UPDATED
National Weather Service Shreveport LA
1136 PM CST Thu Dec 14 2017

.AVIATION...
VFR conditions will continue through the 15/06Z TAF period. An
extensive area of cirrus will continue to shift northeast across
much of the region overnight, with some AC cigs possible late at
the LFK terminal. These cirrus cigs may begin to temporarily clear
portions of NE TX/SW AR Friday with the passage of a weak
shortwave trough, before returning during the late evening as SW
flow aloft becomes re-established over the Srn Plains ahead of a
closed low over Wrn Old MX. Can`t rule out a sct cu field now over
Ern OK/Wrn and Nrn AR spreading SE into SW AR by/after 12Z
Friday, possibly affecting the TXK and ELD terminals, before
thinning out during the afternoon as drier air continues to spill
S in wake of a cold fropa over SE TX/Srn LA. N winds 5-10kts
tonight will become NNW 5-7kts after 16Z Friday. /15/

UPDATE...
To sky cover for the overnight.

DISCUSSION...
The clouds are running along a diagonal that appears may hold for
most of the night. However, the clouds are thinning overhead on
GOES 16 and as such no changes were made to temps as dew points
are already down there for most sites and the winds are keeping
them on the fall where blowing. Calmer wind at times overnight
will allow a quick fall. In contrast, Shreveport just went back
up with wind from 46 to 50, so it will be a fickle night on
getting it right. /24/
