.DISCUSSION...
Issued at 339 PM CDT Fri Jul 11 2025

Water vapor imagery from this afternoon reveals a relatively flat
upper air flow regime across the CONUS although with two notable
short waves seen rippling across central US. The first wave
stretches from the Upper Midwest into eastern KS/OK while the other
wave extends from North Dakota back into the Central Rockies.  The
first wave is leaving an area of subsidence behind it across the
western half of KS with little in the wave of cloud cover. However,
the second wave is already helping initiate convection along the
Front Range to Sangre De Cristo ranges in CO and NM. Closer to the
surface, the aforementioned first wave has helped push a weak front
southward earlier this morning but now nearly stalled just south of
the Kansas...Oklahoma state line. While there is decent MLCAPE of
2000-2500 J/kg along this boundary and only modest inhibition...the
subsidence behind the exiting wave is helping create a very dry LCL-
LFC layer that is limiting initiation as noted by only shallow CU.
While there is still some potential (<20%) for deep convection to
initiate near the KS...OK state line into the early evening... the
overall shear profile as noted in the KDDC 88D VWP profile is very
weak which suggests any convection that does develop will struggle
to organize. The lone exception to that rule is higher DCAPE values
in excess of 1000 J/kg that would support decent downdraft
potential even with shorter duration storms.

Otherwise...attention will shift toward later this evening into the
overnight hours as the aforementioned wave across the Central
Rockies pushes a secondary cold front into western KS. While MCS
maintenance will be marginal...there is a modest 30-35 kt LLJ that
noses into southwest Kansas by 06Z right as the front moves into the
area.  This should allow convection to move out of CO/NM and blossom
over far western KS by midnight. With shear profiles remaining
weak...unlikely this will result in a widespread severe convective
threat.  This convection will then slowly shift east-southeast
across the area during the overnight to early morning hours with the
highest probability (around 30%) for rainfall to exceed 0.5-in
generally west of US Highway 283.

Other than some lingering showers/thunderstorms during the morning
to early afternoon hours...Saturday will see the short wave and
associated front slide east into the lower Great Plains. This will
result in subsidence and dry weather prevailing by mid afternoon
along with decreasing cloud cover. Nonetheless, this will result in
a cooler start to the weekend with afternoon highs staying in the
80s.

For the remainder of the weekend into early next week ENS and GFES
means reveal upper ridging building over the Central Rockies and
adjacent Central High Plains with dry conditions prevailing
(probability of exceeding 0.10-in near zero). This will also result
in temperatures gradually increasing back into the 90s for afternoon
highs by Tuesday. For the middle to end of the week there are some
signs in the ENS and GEFS means of another monsoonal oriented
moisture plume pushing into the region that interacts with a
northern stream short wave. This will bring the next associated
chance for thunderstorms and slightly cooler temps (probability
of exceeding 90 F <30%)

.AVIATION /06Z TAFS THROUGH 06Z SUNDAY/...
Issued at 1100 PM CDT Fri Jul 11 2025

Radar imagery at 04z Sat showed numerous thunderstorms across
eastern Colorado, developing as a cold front slides south
through the region. Shower and thunderstorm coverage is expected
to increase 06-12z Sat, as another complex of rain showers and
embedded thunder move into SW KS. Confidence of showers and
thunderstorms is highest at GCK/LBL/DDC, but kept the HYS TAF
dry for now. Outflow wind gusts to 40 kts are possible. Rain
showers may linger much of Saturday per the 00z NAM solution,
but even so, VFR is expected with midlevel clouds prevailing.
Light northeast winds will persist through this TAF period,
outside the influence of any convective outflows.
