.DISCUSSION...
Issued at 1128 AM MST Wed Nov 6 2024

IR currently depicts the upper level trough positively tilted
south of the CWA now up to the upper Great Plains. Ridging has
begun to build in from the west and southwest giving way to
pristine late fall conditions in the coming days. Winter storm
activity has pushed east with lingering clouds covering some of
the CWA clearing west to east this afternoon. They hang on in
the CPR and I-25 area longest towards late afternoon but will
see enough sun to warm to above freezing. As a result of
clearing earlier than anticipated, temperatures have been bumped
up 3-5 degrees to stay above freezing for most of the CWA.
However, with the clearing skies and winds diminishing this
afternoon and overnight, temperatures will plummet to the
coldest thus far this season with single digits east of the
Divide and teens to the east.

With ridging in place, expect a warming trend and continued dry
conditions to end the work week and into the weekend. Light
winds and mainly clear skies with no impacts expected. By late
weekend on Sunday and into Monday, the upper level pattern
becomes more meridional and active as the main finger of the PFJ
dips back south off the Pacific northwest coast to the upper
Rockies. Cold frontal passage sometime Monday night with the
main trough on Tuesday. Impacts are not known specifically at
this point in time but with the warmer temperatures above
average, expect liquid precipitation east of the Divide and snow
to the west along with higher elevations. It looks to be quick
and progressive giving way to another ridge to build in to push
that system out looking to be limited in impact at this time.
Cooler temperatures back to more seasonable looks to occur
through mid next week with warming into the later half. Time
will tell, so stay tuned for updates in the coming days and
enjoy the nice weather through the weekend.
