.DISCUSSION /Through Wednesday/...
Issued at 1022 PM MST Wed Feb 4 2026

Water vapor imagery shows a large ridge aloft has moved over the
western US. This anomalously strong ridge will dominate the
weather in Colorado through Monday. Highs across the plains will
be in the low to mid 60s each day which is roughly 20 degrees
above normal. Record highs for Denver during this stretch are in
the low 70s so it appears Denver will avoid record warmth although
some days may get close. Otherwise, each day will have mostly
sunny and dry conditions.

The concern during this period will be elevated fire weather
conditions on Saturday and Monday. Relative humidity will drop to
between 10-18% across the plains each of those days. A weak
shortwave trough on Saturday and an approaching shortwave trough
on Monday will increase winds across the far northern plains of
Colorado near the Cheyenne Ridge. If wind gusts are expected to
increase beyond the current forecast, highlights could be
warranted.

Global models and their ensembles are still in agreement that a
pattern change will take place on Tuesday of next week. A
progressive pattern will allow many different shortwave troughs to
move onshore over the California coast and progress eastward
towards Colorado. The signal is still strong for multiple light
snow events in the Colorado mountains. However, there is lower
confidence in the plains receiving any precipitation. While these
light snows in the mountains will help the drought, there is not a
good signal for a bigger system that could bring enough
precipitation to make up ground on our snowpack deficit.
