.KEY MESSAGES...

-Showers and thunderstorms will develop over portions of the
 area this afternoon, mainly in northwest Kansas and southwest
 Nebraska. A severe storm or two capable of producing large hail
 and damaging winds. There is a less than 5 percent chance of a
 brief tornado occurring as well.

- Some frost may be possible across higher elevations of Kit
  Carson, Cheyenne and Yuma counties Friday morning.

- Gusty to strong winds possibly gusting up to 55 mph may occur
  Saturday in wake of another cold front.

- Freezing (or near-freezing) temperatures are possible across
  portions of the area Sunday and Tuesday mornings.

.SHORT TERM /THROUGH FRIDAY NIGHT/...
Issued at 1128 AM MDT Thu Oct 16 2025

The area has strong synoptic forcing in place today due to being on
the right exit region of 700,500 and 250mb jets and eventually being
on the left entrance region further increasing lift across the area.
Due to the this scattered storms are forecast to continue for
most of the day. Still anticipating a window of strong to severe
storms this afternoon as a corridor of better shear moves into
the area along with steepening mid level lapse rates just ahead
of a cold front. Have tailored the forecast towards the NSSL-WRF
as this has been the only CAM to show any hint of ongoing
convection at this time. Meager CAPE values are forecast to be
in place of 500-750 j/kg but some guidance does have pockets of
1000-1500 j/kg which would be where the relative higher severe
threat would reside with perhaps some transient supercell
characteristics given bulk shear of 50-60 knots in place. Large
hail and damaging winds appear to be the main threats with hail
around quarter size, but perhaps larger if a longer lived
updraft can occur given the strong amounts of shear. As for
winds, currently thinking that gusts of 60-70 mph would be the
most likely given lapse rates of 7-8 c/km which is a bit on the
lower end of what I would like to see for lapse rates but given
the strong jets aloft some of those winds could get mixed down.
There also may be window or two for a brief tornado. The first
would be during the early to mid afternoon in the form of a
landspout along the cold front as it slowly moves to the
southeast. A secondary wind would be between 23-01Z this evening
as the low level jet kicks in and ramps the 0-3 and 0-1 SRH up
in excess of 350 m^2/s^2 assuming storms and any inflow remain
from the warm side of the front. The front is then forecast to
move a bit quicker after sunset which will then undercut any
showers and storms leading them to become more elevated before
eventually dissipating as drier air moves in. As the drier air
moves in clouds will then clear out as overnight lows fall into
the mid 30s across eastern Colorado to the low 50s across the
eastern portions of the area. Wouldn`t be overall surprised at
some frost across western portions of the Yuma, Kit Carson and
Cheyenne counties in Colorado where winds may briefly go light
but westerly allowing for some radiational cooling potential.
Will forego a Frost Advisory due to lack of confidence and
limited coverage of any frost potential.

Friday, a low pressure system continues across the northern Plains
but moves away into the northern Great Lakes region lessening the
influence of it for the area. Some breezy winds gusting 20-30 mph
may still occur during the morning hours for eastern portions of the
forecast area but as a whole think that this period of windy
conditions will come to an end. More stable air is anticipated
in wake of the previous day`s front as well as dry conditions
along with more seasonable conditions are forecast with highs
forecast in the upper 60s to low 70s across the area. A surface
high then moves across the area shifting winds from the north to
the south.

.LONG TERM /SATURDAY THROUGH THURSDAY/...
Issued at 113 PM MDT Thu Oct 16 2025

A stronger cold front is forecast to move through Saturday which may
bring some stronger winds with it again. 12Z GFS shows strong
pressure rises of 4-7mb over 3 hours just behind the front with an
increasing 850mb and 700mb. GFS and ECMWF both show strong 850 and
700mb jets in place with the 700mb jet of 40-55 knots so will
continue to monitor this as the current expectation is that
there is the potential for some of that to mix down to the
surface. Will also need to keep an eye on blowing dust potential
but with the rainfall going on currently it may have
resaturated the top layer of soil to help keep the dust at bay.
Behind the front 2-2.5km lapse rates do fall which suggests some
capping but am a little skeptical on the strength of the winds
as this occurs.

Saturday night and into Sunday in wake of the front, clearing
is forecast to occur along with much drier air moving into the
area as a surface high moves in from west to east as well. As
the surface high moves in winds are forecast to become light and
variable setting up for a radiational cooling night. It
continues to appear that frost and freezes will be on the table
for most of the area with the most likely area for freezes
lying across eastern Colorado and southwest Nebraska. A
limiting factor would be how quickly the surface high moves
across the area as winds will turn to the west- southwest in
wake of it which would support warming.

Sunday and into the start of the new week, an active pattern
continues as troughing continues to move across the northern Plains
continuing breezy winds across the area. Drier air will remain in
place but temperatures are currently forecast to remain
seasonal which may lead to some elevated to locally critical
fire weather conditions so will need to keep an eye on this. Yet
another cold front is forecast to move through bringing another
potential for frost and freeze concerns to the area. ECMWF
suggests a broader surface high across the area which leads to
me think that any frost/freeze may be a bit more widespread than
Sunday morning. Will preclude from introducing any frost
wording into the forecast at this time until we see what occurs
on Sunday morning. Our active pattern may continue as a more
compact trough may move across the Plains.

.AVIATION /18Z TAFS THROUGH 18Z FRIDAY/...
Issued at 1056 AM MDT Thu Oct 16 2025

A line of showers and storms continues to slowly drift to the
east. At this time confidence is higher in these affecting the
MCK terminal with a lower chance for GLD just based on the
current orientation. Around 22-23Z another round of showers and
storms is forecast to develop to the northwest of the GLD
terminal and move slowly to the NNE. These have the potential to
have heavier rainfall and perhaps some hail and wind threat as
well. After the rainfall comes to an end winds will turn to the
north along with the potential for a transient period stratus
just behind a cold front. Any stratus is forecast to be short
lived followed by a clearing trend as drier air moves in.
