.DISCUSSION /Through Saturday/...
Issued at 1033 PM MST Sat Nov 7 2026

Upper level high pressure will further build into the area Sunday
and Monday, keeping well-above normal temperatures and dry
conditions across the area. Mostly sunny to partly cloudy skies are
forecast for the next two days, with highs approaching 70 degrees
each afternoon for portions of the plains.

On Tuesday, the flow aloft becomes more zonal, and potentially even
a little northwesterly. A shortwave trough is forecast to approach
the area from the northwest, bringing slightly cooler temperatures
aloft and increased cloud cover for Tuesday afternoon. This will
allow temperatures to drop a few degrees for Tuesday afternoon in
the higher terrain and portions of the plains. A cold front is
forecast to move through sometime mid Tuesday into early
Wednesday. Models vary pretty significantly with the positioning
and strength of the shortwave and therefore the strength of the
cold front. The GFS wants to bring the shortwave further south
into the area, with a much stronger cold front. It also brings the
700mb jet over the northeast plains, putting breezy winds across
the area late Tuesday into Wednesday. This solution would allow
for low end rain chances in the higher terrain, warmer
temperatures across the northern plains on Tuesday from strong
downsloping, and cooler temperatures Wednesday. However, other
models have a less potent shortwave staying more to our northeast.
With this solution precipitation chances would remain near zero,
surface winds would be much lighter, and temperatures would drop
slightly for the middle of the week, but not as significantly as
the other scenario.

For Thursday into the weekend, an upper level ridge builds over the
area, bringing temps back to 10-15 degrees above normal for the
plains on Friday. Looking at ensembles, there is not a single member
of the most recent GFS and ECMWF runs that have even a trace of rain
for Denver over the next 7 days, so confidence is high in conditions
staying dry for the plains (unfortunately).

.AVIATION /06Z TAFS through 06Z Monday/...
Issued at 1033 PM MST Sat Nov 7 2026

VFR conditions will persist through the TAF period with only a
FEW-SCT high clouds above 20,000 ft AGL and no visibility
restrictions. Light winds will prevail. One weak northerly surge
had just pushed across KDEN, delaying the eventual development of
the normal S-SW drainage winds til about 08Z. Those will then
persist through early Sunday morning with a mainly light S-SE
wind at 5-9 kts expected through most of the day (15Z-00Z), with
just a 20-30% chance they just become VRB around 5 kts 18Z-00Z.
Look for a transition back to normal S-SW around 10 kts by 02Z.
