.SHORT TERM /THROUGH FRIDAY NIGHT/...
Issued at 1245 PM MDT Tue Jun 24 2025

Southwest flow aloft continues with another weak embedded wave
initiating thunderstorms this afternoon along the Front Range.
Moist southerly flow at the surface has resulted in a moderately
unstable environment. Storms will move east-northeast and reach
far northeast Colorado around 23-00z, continuing on that track
through this evening. Despite ample instability, deep layer
shear is modest at best, with 20-30 kts expected by the time
storms reach the northwest part of the area. DCAPE is also
rather limited at around 500-800 j/kg. Those two factors will
limit the severe risk, but still may see a brief flare-up with
winds as cold pools strengthen, as well as a low-end hail threat
with more organized updrafts. Best storm chances will be north
of Interstate 70, with more scattered activity elsewhere,
lingering into the overnight hours. Low temperatures will be in
the 60s.

Southwest flow aloft continues on Wednesday with another
embedded shortwave trough. Storms expected to initiate a little
earlier compared to today in the mid afternoon, and probably
developing in the area rather than moving in from the west,
along remnant outflow boundaries from overnight convection. HREF
ensemble mean SBCAPE peaks at around 1000-1500 j/kg and deep
layer shear at around 15-25 kts, both parameters highest north
of Interstate 70. This will lead to another marginal risk type
day with low- end severe threat of wind and hail with stronger
updrafts. Storms diminish and move east overnight. High
temperatures on Wednesday will be mainly in the 80s and lows
Wednesday night mainly in the 60s.

Thursday and Friday...upper ridge strengthens over the southern
plains with the main storm track retreating into the northern
plains. Models show only isolated convection Thursday afternoon
and evening with the last of the shortwaves in the weakening
southwest flow aloft. On Friday models are mostly dry.
Temperatures will be warming up with the strengthening ridge,
with highs on Thursday in the upper 80s to lower 90s and highs
on Friday in the low to mid 90s.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
Issued at 1245 PM MDT Tue Jun 24 2025

The flow aloft remains weak with upper ridging predominant.
There does appear to be weak forcing on Saturday moving through
the zonal flow atop the ridge which combined with intense
surface heating may pop a few isolated afternoon and evening
storms. However, storms should be pulse in nature and poorly
organized due to lack of shear. The upper ridge is forecast to
amplify over the Rockies through early next week with a gradual
shift to more of a weak northwest flow over the plains. This
will allow a shallow cold frontal passage sometime on Sunday,
followed by post frontal upslope early next week. Some
thunderstorm development may occur along the front on Sunday,
then again Monday and Tuesday on the higher terrain to the west
in the upslope regime, but deep layer shear remains weak and
will limit storm organization and coverage. Temperatures remain
above normal on Sunday, in the low to mid 90s, but return to
near normal Monday and Tuesday.

.AVIATION /00Z TAFS THROUGH 00Z THURSDAY/...
Issued at 422 PM MDT Tue Jun 24 2025

Main focus through the evening will be shower and thunderstorm
activity for each terminal. Confidence is a little higher for
KMCK being impacted so am opting for a tempo versus the prob30
for KGLD as KMCK has the better potential of a cluster of storms
moving through versus more isolated for KGLD. A localized 850mb
jet is forecast to develop across western Kansas overnight
leading to LLWS concerns for KGLD; will need to keep an eye on
for KMCK in case the jet is stronger than what guidance
suggests. Southerly winds are forecast to redevelop Wednesday
followed by another potential for storms for KGLD during the
afternoon and then for KMCK but after the end of this TAF
period.
