.DISCUSSION...
Issued at 1200 PM CDT Thu May 21 2026

WV imagery indicates a southwest flow aloft prevailing across
the Western High Plains downstream of an shortwave trough digging
southeast through the Central Rockies. Near the surface, broad
high pressure continues to drift east across the Great Lakes
Region. Meanwhile, low pressure is developing across southern
Colorado.

Thunderstorm chances (50-70%) increase early in the period as the
SREF indicates an upper level shortwave trough dipping southeast
into the northern Colorado Rockies tonight, supporting an
increasingly difluent southwest flow across the high plains of
eastern Colorado/western Kansas. Ahead of the approaching system,
prevailing southeasterly upsloping will continue to reinforce
deep layer moisture across southwest/central Kansas with surface
dewpoints holding in the mid/upper 50s(F), providing marginal
instability with MUCAPE values upward of 500 to 1000 J/kg, the
highest out near the Colorado line. Combined with steepening
mid-level lapse rates and favorable deep layer shear, thunderstorms
are expected to develop late this afternoon in southeast Colorado
as ejecting H5 vort maxima interact with a quasi-stationary
dryline then drift eastward, potentially into extreme southwest
Kansas this evening. This is suggested by some CAMs and the HREF
painting a 50-70% probability of 6-hr QPF exceeding 0.25 of an
inch across portions of extreme southwest Kansas near the Oklahoma
line by late evening. Severe potential will be limited with only
modest instability present and marginal southwesterlies (+50kt)
aloft. There is a minimal chance that showers/thunderstorms
developing along an advancing cold front late afternoon into
early evening in northeast Colorado, push southeast into northwest
Kansas late this evening through the overnight. This is suggested
by the HREF pointing to only a 10-30% probability of 6-hr QPF
nudging over 0.1 of an inch by early Friday morning.

After a break Friday, thunderstorm chances (30-50%) return Saturday
on the back side of a departing surface high, setting up an east-
southeast upslope flow across southwest Kansas in conjunction with
the arrival of a projected upper level shortwave trough transitioning
through the Colorado Rockies. Ample moisture will provide sufficient
instability as H5 vort maxima kick out of the Rockies, coninciding
with steepening mid-level lapse rates, setting the stage for potential
thunderstorm development Saturday afternoon/evening across southern
portions of southwest Kansas as suggested by the NBM indicating a
10-30% probability of 12-hr QPF topping 0.25 of an inch by late
Saturday evening.

More seasonal temperatures are expected tonight as prevailing
southeasterly upsloping continues to slowly erode the cooler air
mass that dominated the high plains of western Kansas the last
couple of days. With increased cloud cover and surface dewpoints
holding in the lower/mid 50s(F), look for lows only down into the
lower/mid 50s(F) across extreme southwest Kansas where the HREF
paints a widespread >90% probability of temperatures dropping
below 60F to the lower 60s(F) in central/south central Kansas
where the probability of slipping below 60F is only 30-50%.
Despite a cold front edging through west central Kansas into
portions of southwest Kansas by mid-afternoon Friday, expect
slightly warmer temperatures compared to today as skies clear
out west to east during the day. Expect widespread highs up into
the 70s(F) with the HREF showing an 80-90% probability of
temperatures exceeding 70F by late afternoon. Similar highs are
likely Saturday.

.AVIATION /00Z TAFS THROUGH 00Z FRIDAY/...
Issued at 515 PM CDT Thu May 21 2026

A line of storms in southeast Colorado as of 2215Z will move
through southwest Kansas tonight and affect GCK and LBL
terminals between 01-04Z and DDC between 02-05Z. A second round
of storms will move in from northwest Kansas after 12Z Friday
and affect all the terminals between 12-15Z. With the rain cloud
ceilings will fall to IFR and LIFR flight category between
06Z-18Z Friday. A cold front will move in behind the storms and
a wind shift to the northeast will occur after 15Z. Cloud
ceilings should rise to VFR after 18Z as the storms and clouds
clear behind the front.

.DDC WATCHES/WARNINGS/ADVISORIES...
