.DISCUSSION /Through Thursday/...
Issued at 249 PM MST Thu Nov 6 2025

Water vapor imagery shows a trough moving into Nebraska with
subsident flow moving over Colorado. This trough has been
responsible producing strong wind gusts across our forecast area.
Many wind gusts in the 50-55 mph range have been reported in the
foothills and across the eastern plains mainly close to the
Wyoming border. In addition, this trough has brought snow showers
to the northern mountains. The bulk of the snow showers have
formed in and around Rocky Mountain National Park. Radar shows
these snow showers are diminishing and that trend will continue
this evening as the snow showers will come to an end.

Brief ridging aloft will be over Colorado on Friday. This will
lead to highs 5-10 F above normal with light winds across the
plains.

A strong positively tilted trough will move across northeastern
Colorado Friday night into Saturday morning. This will bring
another wave of light snow showers to the northern mountains. 1-4"
of snow are expected mainly in the Park Range and Medicine Bow
Range. A cold front associated with this trough will move across
the eastern plains around midnight Friday night. During the day on
Saturday, strong winds will occur over the plains with gusts up to
50 mph. The highest wind gusts will be to the north and east of
Fort Morgan. The cold air behind the front will result in the
coldest night of the season Saturday night. Plenty of locations
across the plains will see lows in the teens.

A strong and broad ridge aloft will move over Colorado Monday
through Friday of next week. This will lead to an extended period
of well above normal temperatures with dry conditions. Ensembles
guidance shows this period could see multiple record highs tied or
broken as highs in the upper 70s are possible across the plains.

Light winds and VFR conditions are expected today with increasing

although the direction could be variable. A cold front will move
across the terminals around 07-10Z. This front will have gusts up

sustained around 10-12 knots out of the northeast for a couple of
hours after the front. After a brief period of light winds in the
morning hours, gusty northerly winds are likely to develop.
Depending on how far west the strong northerly winds get, DEN
could gust up to 30 knots.
