  afternoon. An isolated instance or two of gusts up to 60 mph
  can`t be ruled out across Yuma, Dundy and Cheyenne county
  Kansas.

.SHORT TERM /THROUGH TONIGHT/...
Issued at 1141 PM MST Fri Dec 5 2025

Sat-Sat night: WNW to NW flow aloft will persist over the
region. Shortwave energy over the northern Rockies at 06 UTC
(per SPC mesoanalysis 400-250 mb Pot Vort) will progress ESE-SE
across the Northern/Central Plains today.. accompanied by a
modest surface low that will track ESE-SE from the NE Panhandle
(~12Z) to central NE (~18Z this afternoon) and Kansas City
(00-06Z this evening). High-res guidance continues to suggest a
brief potential for light precip around sunrise (~12-14Z) in
southwest Nebraska. The presence of a dry low-level airmass with
southern extent (toward the KS-NE border) may preclude
measurable precipitation in the Goodland county warning area.
While an increasingly prominent warm-nose will be present when
precipitation is possible (800 mb temps rising to 2-3C in the
~12-15Z time-frame), forecast soundings suggest that vertical
wetbulb profiles will remain at-or-below freezing (supportive of
snow). Breezy NW winds will develop early this afternoon.. as
the surface low progresses east of the Tri-State area. Winds
will weaken after sunset.

.LONG TERM /SUNDAY THROUGH FRIDAY/...
Issued at 122 AM MST Sat Dec 6 2025

Starting the extended period Sunday morning. Weak omega around
1-3 mb is forecast to be in place along and east of Highway 83
around sunrise with a deep saturated layer in place from 500mb
to the surface via 03 RAP13 cross sections as a cold front moves
through the area. Further looking at soundings from the same
time frame shows this as well with the entire profile below the
0C line which suggests to me snow would be the main p-type
especially across Hitchcock and Red Willow counties. This is
however very similar to the other morning when freezing fog and
freezing drizzle was present across northwest Kansas and led to
very slick roadways for the morning hours. I do notice as well
around 12-15Z warm air advection in the 850mb layer which
further raises my concerns for freezing fog/freezing drizzle to
occur as a warm nose may develop. Surface winds are also
forecast to be light from the east which is also
climatologically favorable for fog or drizzle. 00Z NAM12 is also
similar on the location but doesn`t show the omega and has a
little more drier air in the 750-700mb layer. Due to the shallow
nature of the lift and it being just below the dendritic growth
zone think the drizzle or fog is the more likely solution but
confidence in this is only around 10-20% at this time as I
would like to see a little more consistency with guidance. The
00Z HREF is ironically enough only showing around 15% chance of
ceilings falling below 1000 feet AGL which for freezing drizzle
and obviously fog the lower the ceilings the better for the
occurrence. Should this occur any fog or drizzle should be out
of the area around 12pm CT. Temperatures for Sunday are
currently forecast to be around normal for early December in the
upper 30s to mid 40s with the warmest across western portions
of the area as downsloping occurs and the cool air mass

Monday, northwesterly flow shifts a little further to the east which
shunts any potential disturbances away from the area this looks to
continue through midweek as well as we are forecast to see a warming
trend with Tuesday looking to the warmest with highs in the 60s.
Along with dry conditions. Breezy to gusty winds are forecast
as well Tuesday as the 850mb wind field increases. With the
warmer temperatures may need to keep an eye out for some
elevated fire weather conditions primarily along and north of
Highway 36.

Tuesday evening and into early Wednesday morning another clipper
system moves across the northern Plains and sends a cold front
through the region. GEFS ensemble members are split on the amount of
moisture in place ahead of the front which will depend on if
precipitation can occur with it. There is also potential for a
stronger front Thursday morning associated with a shortwave within
the northwesterly flow as the clipper system shunts the
northwesterly flow back to the west and we enter the same
pattern as we have been in. 00Z GEFS shows a bit more promise on
precipitation potential with this than what I`ve been seeing
the previous days but looks like it is consistent with what the
18Z run was showing as well so will be interesting to see if its
picking up on something or if these are outlier runs. However
on the flip side the 00Z run of the ECMWF-AIFS ensembles has the
area dry. Will leave with a dry forecast for now due to the
significant differences of guidance but is for sure something
to keep an eye on.
