.DISCUSSION /Through Saturday/...
Issued at 156 PM MDT Sat Sep 6 2025
Water vapor satellite imagery showing a shortwave trough tracking
across Utah with scattered/numerous showers and thunderstorms
over eastern Utah and western Colorado. As the shortwave tracks
northeast eastward it shears out some, losing some lift. In
addition to this, the airmass is more stable and drier across
eastern Colorado. This leads to the best chance for showers and
thunderstorms to be over the higher terrain. As the showers move
off the higher terrain, they are expected to be short lived as
they run into a more stable/capped airmass. With the shortwave
moving through the eastern part of Colorado tonight, can`t rule
out a few light showers.
For Sunday, flow aloft turns more westerly and is expected to
help decrease the amount of smoke in the air. Isolated/scattered
showers and storms are expected throughout the area Sunday.
Moisture and instability remains limited, resulting in mainly weak
showers and storms. A lee-side trough/dry line sets up over far
eastern Colorado. Better moisture will reside east of the surface
trough with dew points in the upper 50s. A few of the storms, may
be strong and can`t rule out a couple severe storms as well over
far eastern Colorado.
The upper level ridge that`s been off to our west slides east
across the Central Rockies Monday and Monday night. This is
expected to bring warmer and drier conditions with a slight chance
for a few weak showers and storms over the higher terrain.
Flow aloft turns southwesterly as the ridge pushes east of the
Central Rockies. Still a fair amount of uncertainty on how much
subtropical moisture gets pulled northward by the southwest flow
aloft. Looks to be enough for at least isolated/scattered showers
and thunderstorms each afternoon/evening, mainly focused over the
higher terrain.
For Friday and Saturday, models are hinting at general
troughiness over the western part of the country. This expected to
lead to slightly cooler temperatures and better chances for
showers and thunderstorms.

.AVIATION /06Z TAFS through 06Z Monday/...
Issued at 1143 PM MDT Sat Sep 6 2025
VFR conditions will persist through the period, with less smoke
and no anticipated slant range visibility restrictions. The main
concern will be for isolated to scattered showers and storms with
variable and gusty outflow winds from roughly 21Z-02Z. We`ll
continue with the Prob30 in that period since coverage should be
relatively limited, but sufficient DCAPE for VRB G30-35kts.
Otherwise, slightly more W/SW wind component than normal through
12Z, but light speeds. Winds likely become variable for a few
hours 15Z-19Z in the transition to diurnal northeasterlies after
19Z.
