The episode as NWS GLD wrote it up.

Area Forecast Discussion
National Weather Service Goodland KS
1054 PM MST Fri Nov 29 2019
.UPDATE...
Issued at 935 PM MST Fri Nov 29 2019
Updated forecast to cancel the Dense Fog Advisory since all areas
of low visibility have moved out of the area as south winds have
spread northward across the forecast area. There may be a brief
period where far northeast Colorado sees low clouds and visibility
reduced to one half mile or less over the next few hours as a
small area of low clouds in advance of the surface low center
lifts northeastward across far northeast Colorado into the
Nebraska panhandle region.
UPDATE Issued at 715 PM MST Fri Nov 29 2019
Updated forecast to cancel dense fog advisory for areas where the
winds have gone south and visibilities have improved. Areas where
winds remain east to southeast continue to see visibilities down
around 1/2 to 1/4 mile.
&&
.SHORT TERM...(This evening through Saturday)
Issued at 339 PM MST Fri Nov 29 2019
Dense fog will continue through this afternoon, hopefully ending
from the SW sector of our CWA to our NE area by 6Z. Tonight we
will start to clear out as our winds become southwest around 20 to
30 mph, with gusts starting to come up to 45 mph.
Forecast builder was a bit of a challenge today and to generate
the widespread fog, not captured by guidance, went in and adjusted
PotFog grids to change wording to reflect current and expected
trends through the early evening hours.
Tonight, we will see a return of quite a cocktail of freezing and
non-freezing precipitation in the form of rain and drizzle. It
will be a messy night,especially for our northernmost counties.
As this system lifts and exits northerly, we will see dryer and
windy conditions take over.
Saturday, guidance has continued to agree and hone in tomorrow's
wind event. Went straight CONSMOS for winds on Saturday, and
bumped gusts up additionally. Sustained winds will range in the 40
to 55 mph range with gusts up to 75 mph expected. Continuing the
High Wind Warning. May have to extend the High Wind Warning's
duration, as some of the local high-res guidance is dragging the
event out longer.
Less concerned with blowing snow as much of the snowpack has had
additional non-freezing and freezing precip in sporadic intervals
throughout today. This has left most of the area to be covered in
thick impacted snow. But there is still a chance for blowing dust
from our southern areas which received little to none snow and
rain.
Saturday's highs will sit in the mid 30s to mid 40s. Cloud cover,
WAA, and snowpack will create a wide gradient of temperatures
with our coolest temperatures in our NW CWA and warmest in the SE
CWA. Overnight lows will be in the upper teens to mid 20s.
Quieter weather starts Sunday.
.LONG TERM...(Sunday through Friday)
Issued at 1257 PM MST Fri Nov 29 2019
Upper ridging will dominate the early part of the period,
resulting in dry conditions and temperatures near to slightly
above normal. Remnants of an upper low over the west will move
across the southern plains on Thursday, taking most of the
precipitation chances with it, though cannot completely rule out
an isolated rain or snow shower. Upper ridging will quickly
rebuild behind it on Friday. Hard to identify any impactful
weather in this pattern.
&&
.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 1030 PM MST Fri Nov 29 2019
Skies have cleared out in the dryer south southwest flow ahead of
strong low pressure system lifting out of northeast Colorado into
Nebraska. Southwest winds will be gusting intermittently through
the remaining overnight hours with LLWS due to 50-55kt winds
immediately above the near surface temperature inversion. By 15Z,
expect the surface inversion to mix out with much stronger winds
reaching the surface with gusts over 50 kts by 17Z, gusty winds
will continue through Saturday evening with some moderation.
MCK will see several more hours of low ceilings producing LIFR to
IFR conditions with a quick change to VFR after 09Z as winds turn
southwest and drier air makes it over the TAF site. There will be
LLWS through 09Z with southwest winds just above the surface
inversion gusting to 45kts. VFR conditions will continue through
the remainder of the TAF period with gusty west winds after 14Z
continuing to increase through the day with a turn to the
northwest and gusts over 50kts by 20Z. Gusty winds will continue
into Saturday evening with some moderation.
