.DISCUSSION /Through Friday/...
Issued at 240 PM MST Fri Jan 9 2026

Some flurries have lingered for quite a while across the southern
foothills and Palmer Divide today. These will come to an end
around sunset as the daytime heating ends. Clouds will clear
tonight with dry conditions. This will allow temperatures to fall
below normal with teens across most of the urban corridor and
plains with single digits on the Palmer Divide and in the usual
cold spots like Greeley and Limon.

From Saturday through the following week, Colorado will be on the
eastern edge of an anomalously strong ridge over the western US.
This will lead to an extended period of dry weather due to
subsident flow. Temperatures aloft will increase through Tuesday
with temperatures warming above normal. Monday and Tuesday will
have highs in the upper 50s to 60s across the I-25 corridor and
plains. Winds will be breezy each day but there are not expected
to be any significant high wind events. Some elevated fire weather
conditions may develop across the northeast plains especially on
Tuesday.

Shortwave troughs within the northwesterly flow aloft may move
over Colorado Tuesday night and again on Thursday into Friday. The
Tuesday night trough may bring very light precipitation to our
forecast area. The Thursday trough may also bring light
precipitation and could allow colder temperatures to slide across
the northeast plains.

.AVIATION /06Z TAFS through 06Z Sunday/...
Issued at 1042 PM MST Fri Jan 9 2026

VFR conditions through the TAF period. Light SSW winds are in
place across the TAF sites late tonight. Aside from a slight
increase in magnitude around 9Z tonight at KDEN, expecting winds
to generally remain where they are at tonight. Winds at KBJC
shift slightly more westerly between 9-11Z with increasing
magnitudes through the morning. Hi-res solutions are split on NW
winds mixing down in the afternoon. Have introduced a slightly
more NW component for the afternoon for now, but if winds do mix
down, expect a slightly more northerly component to afternoon wind
directions compared to the current TAF, with 20-25kt gusts
possible from roughly 19Z-23Z.
