DISCUSSION

Issued at 240 AM MDT Sun Sep 27 2026

Will see southwesterly flow aloft today and expect about 10 degrees of warming from yesterday ahead of an approaching Pacific trof. Moisture will increase and expect isolated to scattered showers tonight and Monday with the most significant activity in the eastern mountains. As the upper trof pushes east Monday will once again see cooling and about a 10 degree drop from today. Tuesday through next Sunday will be a dry period as we enter an extended period of generally well above normal temperatures as ridging will be the rule for quite some time.
