.DISCUSSION /Through Saturday/...
Issued at 1239 PM MST Sat Nov 14 2026

A negatively tilted trough is moving over the area this afternoon.
Moisture has increased significantly at mid and upper levels as this
system approached the area. As of early this afternoon, the DCVZ
was just to the east of Denver, with very light showers to its
east and north. We still have a bit of a dry layer around 750mb
across the plains, and with how light the precip is, it could
struggle to make it to the ground in some areas until the layer
starts to saturate more. Overall rain amounts are expected to be
very light for much of the plains. Snow showers are moving into
the mountains from the west and south as of early this afternoon.
Coverage of snow showers this afternoon and evening will be best
south of I-70, with most likely accumulations around a trace to 3
inches above 9000ft. Elevations around 8000ft to 9000ft could see
a rain/snow mix today, but accumulations are unlikely.

Overnight, we`re expecting more fog development across the plains.
The REFS currently has a medium to high chance (50-75%) that
portions of the I-70 and northern I-25 corridors will see fog with
visiblities less than 0.5 mile in the early morning. Fog should
start to clear around 10AM give or take an hour.

Upper level ridging begins to build over the area again on
Sunday. Warmer and drier conditions will prevail Sunday through
much of Tuesday. On Tuesday, an upper level trough will move onto
the West Coast. Winds at mid levels will strengthen as the
pressure gradient tightens between the upper ridge and trough.
However, the strongest winds are forecast to remain to the south
and east of our area. The trough will weaken and move east,
sending a shortwave through the area early Wednesday. Precip
chances will increase late Tuesday in the higher terrain as the
shortwave approaches. The shortwave will be moving rather quickly
and the southwesterly to westerly winds aloft are not super
favorable for our area, so impacts from this event will be rather
limited with snow totals around an inch or less for the higher
elevations. For the plains, a cold front is forecast to move
through sometime Wednesday, bringing slightly cooler temps for
Wednesday into the end of the work week. Rain chances remain low
