.DISCUSSION /Through Monday/...
Issued at 1111 AM MST Mon Nov 9 2026

Northern Colorado remains on the edge of a broad upper level ridge
today, with weak zonal flow aloft. The little moisture aloft has
been enough for a few cirrus clouds closer to the state border.
High temperatures are still expected to warm into the upper 60s
across most of the plains this afternoon with light winds.

Tomorrow will feature much of the same weather, with temperatures
again in the upper 60s. A shortwave moving from the northern
Rockies into the central Great Plains will also drag a weak cold
front through the region. Some gusty winds will be possible across
the northern/northeastern portions of our forecast area during the
afternoon into Tuesday night. That could lead to some spotty
elevated/near critical fire weather conditions across the plains,
generally north of Highway 34.

Temperatures are expected to be a few degrees cooler on Wednesday,
though highs should still reach the low/mid 60s across the plains,
which is several degrees above normal. By the latter half of the
week, a stronger upper level ridge is expected to build across the
Four Corners region, leading to warmer and dry weather. It
wouldn`t be surprising to see one or both of Thursday/Friday to
end up in the low 70s.

The next potential for precipitation in our CWA will come this
weekend, as guidance tries to push a weak trough across the region
by Saturday. This system won`t feature any significant synoptic
scale ascent and only some light rain and snow showers are
expected across the high country during the weekend.

Quiet weather looks to continue into early next week, with hints
of a cooler/more active forecast pattern in the 8-10 day period.

.AVIATION /18Z TAFS through 18Z Tuesday/...
Issued at 1051 AM MST Mon Nov 9 2026

VFR will continue through the TAF period with cirrus clouds at
times above 20,000 feet MSL. Light and variable winds at the
moment will turn easterly and increase to 10-15 knots with gusts
to 20 knots after 19Z. Winds will then turn clockwise after 00Z
Tuesday and become a typical southerly drainage direction by 06Z.
Once the southerly drainage winds end, light and variable winds
are expected for most of Tuesday.
