Area Forecast Discussion
National Weather Service Shreveport LA
1008 PM CDT Sat Nov 6 2021

.UPDATE...

At this hour, clear skies and calm winds will once again allow 
radiational cooling to kick in across the Ark-La-Tex overnight. 
This will boost the development of widespread patchy fog lingering
into the early morning hours with dew point depressions below 3 
degrees in most areas.

Minor adjustments were made to sky grids to account for the speed
and magnitude of fog and low cloud deck development, otherwise, 
no additional forecast grid adjustments were necessary at this 
time. /16/

AVIATION...

For the 07/00Z TAF update, calm winds will be further established
under surface high pressure as the part of the center of the air 
mass moves over our airspace through the period. Clear skies now 
(in addition to calm winds) will maximize conditions for 
widespread patchy FG and IFR/LIFR vis/cigs to develop across 
nearly all terminals by 07/10Z-15Z. After the patchy FG lifts, 
light southerly winds slowly return with clear VFR skies 
persisting through the end of the period. /16/
