.DISCUSSION /Through Friday/...
Issued at 1121 PM MST Fri Feb 27 2026

We have one more day of really dry conditions with areas of critical
fire weather conditions before we get a reprieve. RHs will bottom
out in the single digits and low teens across the plains on
Saturday. Winds are expected to be a bit weaker on Saturday than
what we saw on Friday for much of the area, with the stronger
winds staying near the WY/CO border and much weaker winds in the
urban corridor (potentially even a weak east wind thanks to an
anticyclonic circulation). A weak front will push in from the
northeast late Saturday into early Sunday. Breezy NE/E winds are
expected along and behind the front overnight, with gusts around
20 to 35 mph across the eastern half of our forecast area. By
Sunday morning winds will be more SSE, remaining breezy for the
eastern half of the area. For areas further west on the plains
models are hinting at a Denver cyclone developing, giving areas
around the urban corridor light and variable winds throughout the
day.

Over the next week, we`re looking at the potential for three
separate precipitation events for the mountains and two for the
plains. The first will start late Saturday, continuing into late
Sunday/early Monday. Moisture will stream into the mountains at mid
and upper levels Saturday into Sunday. This combined with weak QG
ascent, orographics, and maybe some weak lift from the right exit of
the jet will produce light snow showers late this weekend. Snow
should primarily be confined to the northern mountains, with most
likely snow totals between 1 and 6 inches at the higher elevations.
It is worth noting, that it will be warm and snow levels will be
around 9000ft in the afternoon. Which means areas below 9000ft in
the mountains could see a rain snow mix or even just light rain on
Sunday.

The second event will start sometime late Monday for the mountains/
early Tuesday for the plains, ending late Tuesday into early
Wednesday. An upper level low will form off the West Coast late this
weekend. This low will move towards Colorado for the first few days
of the week, moving over the area Tuesday afternoon. Ahead of this
low, we`ll see strong QG lift and PWATs increasing to 200+
percent of normal for both the mountains and plains. Looking at
model soundings, they`re showing a saturated column with decent
lapse rates, so there is potential for some pockets of heavier
snow/rain. In the mountains we`re looking at most likely snow
totals around 3 to 11 inches for the Front Range and Park Range.
In the I-25 corridor and plains, conditions look too warm for
snow accumulation. But, there is a low chance (
