Area Forecast Discussion
National Weather Service Shreveport LA
1252 AM CDT Wed Mar 22 2017

.AVIATION...
For the 22/06Z terminal forecast VFR will prevail until later
tonight when lower clouds with an approaching cold front from
the North and with low level moisture from the Gulf moves
North, providing MVFR and down to IFR and below conditions.
The lower clouds will be slow to lift during the day Wednesday.
MVFR ceilings may be stubborn to mix out during the afternoon on
Wednesday, especially in the wake of the backdoor boundary. The
boundary will become nearly stationary late Wednesday and then
return as a warm front into Thursday. Surface winds will be light
and variable to light South and Southwest early during the day
South of Interstate 20 while the winds will be East and Northeast
7-12 knots with the passage of the back-door cold front. /06/

.PREV DISCUSSION... /issued 1042 PM CDT Tue Mar 21 2017/

DISCUSSION...
Have made a few changes to the ongoing forecast by adding
areas of fog to parts of East and Northeast Texas and lower
parts of Northwest and North Central Louisiana. Adjusted the
expected sky conditions and current trends in the dew points
and winds. Surface low pressure centered over East and Southeast
Oklahoma and West and Southwest Arkansas with a cold front
from the surface low near Fort Smith Southeast to near Pine
Bluff Arkansas and on into North Mississippi. This boundary will
continue to backdoor into the Four State Region during the
late night and early morning hours Wednesday with the
surface low retrograding into North Texas. Will continue the
current chances for showers and thunderstorms with the boundary
and in its wake over mainly the more Northern half of the
forecast area. By late in the day Wednesday the front will move
into Deep East Texas and across Central Louisiana where it looks
to become nearly stationary overnight Wednesday, and then work
back Northeast on Thursday as a warm front. /06/
