.AVIATION...
For the 18Z TAFs:
A couple more hours of MVFR conditions are expected for KAMA and
KGUY as clearing is coming in from the west. KDHT has already
cleared out, and this will slowly progress east through the day.
Eventually all three sites will be VFR by late this afternoon.
Light wind speeds are expected through this period as well.

.PREV DISCUSSION... /Issued 553 AM CDT Wed Nov 3 2021/
AVIATION...12Z TAFS...
IFR/LIFR conditions expected to continue through 18z for KAMA and
KGUY, with MVFR conditions expected at KDHT. Main concern is cigs
below 1000ft for the LIFR/IFR cat's, but isolated drops in
visibility down to 1SM will be possible. 18-21z conditions should
improve to MVFR/VFR for all TAF sites with skies clearing from
21-03z time period. Later tonight after 06z there may be a chance
for freezing fog to occur at the TAF sites, but confidence is very
low to mention at this time.
