  atleast the next seven days.

.DISCUSSION /Through Sunday/...
Issued at 1155 AM MST Sun Nov 8 2026

An upper level ridge will continue to bring sunny skies, light
winds, and well above normal temperatures through Monday. Cross
sections show the airmass will stay very dry with only some cirrus
clouds at times. High temperatures will run 10F to 15F above
normal with highs in the mid to upper 60s across northeast
Colorado. Even a few low 70s will be possible.

A shortwave trough will pass north of Colorado on Tuesday. The
GFS model has been trending more south with the shortwave trough`s
track compared to the other models, and it continues to do so but
the latest run shows a northward shift. This system will bring
gusty west to northwest winds to northern Colorado Tuesday and
Tuesday night. A weak cold front will also accompany this system,
leading to slightly cooler temperatures for Wednesday. High
temperatures on Wednesday are expected to be in the upper 50s to
lower 60s. No precipitation is expected with this system.

The upper level ridge reestablishes itself over the Intermountain
West on Thursday. Northerly flow aloft will prevail over Colorado
with temperatures reaching the lower to mid 60s. The ridging
slides east and will center over the Central Rockies for Friday
and Saturday. This is expected to push temperatures back into the
mid to upper 60s across northeast Colorado. A few low 70s will
also be possible. The ridge slides east of the region by Sunday as
a shortwave trough moves across the Desert Southwest. Dry
conditions are expected to persist Sunday under a dry southwest
flow aloft. Temperatures will continue to run well above average
(10-15F).

.AVIATION /00Z TAFS through 00Z Tuesday/...
Issued at 430 PM MST Sun Nov 8 2026

VFR conditions to persist through the TAF period.

Current radar shows a south-southeasterly boundary approaching
both KDEN and KAPA at this time (2330Z). Time of arrival tools put
it on the southeast side of KDEN`s airfield by the top of the
hour, slightly sooner to KAPA. Expect a slight increase to wind
speeds as it passes over the airfields, with guidance suggesting
KAPA seeing a few hours of gusts between 15-20kt, and current
radar velocity showing potential for 12-15kt gusts at KDEN. By 2Z,
winds should be transitioning towards drainage, with gust
potential subsiding. At KBJC, current light and variable winds are
expected to remain light through the overnight hours, with a few
hours of southwesterly winds possible before becoming a more
persistent westerly flow through early Monday morning.

For Monday, drainage winds are expected to become light and
variable for a few hours around 15Z/16Z at KDEN/KAPA (12Z at KBJC)
before settling into a southeasterly regime for the afternoon,
and ESE for the evening.
