.DISCUSSION... Issued at 1040 AM MDT Tue Sep 30 2025
Upper level shortwave ridging will continue to quickly traverse west to east across the region with zonal flow settling in thereafter. Zonal flow aloft will dictate the sensible weather conditions on Wednesday with continued above average temperatures and mostly clear to partly cloudy skies.
High pressure aloft will begin building north across the Desert SW starting Thursday and lasting through Friday. Desert lowland temperatures will warm back above average, approaching 90 degrees. Skies will be mostly clear with partly cloudy skies each afternoon, along with light winds.
By this weekend, the next upper level trough will move across the Great Basin and Central Rockies. Upper level flow will become southwesterly, promoting low-end breezy winds on Saturday and Sunday. Temperatures will remain above average with mostly dry conditions expected.

.FIRE WEATHER... Issued at 1040 AM MDT Tue Sep 30 2025
Fire weather concerns are low with low fire danger this week with below normal ERCs and high soil moisture. Min RH 30-40%, dropping into the 20s by the end of the work week with light west winds 7 to 15 mph. Vent rates will be Good today and Wednesday afternoon with transport to the east.
The ridge is expected to break down on Saturday as a closed low sweeps into the Great Basin, leading to an increase in southwest winds that afternoon. Winds will fall short of hitting critical thresholds and with minimum RH only dipping into the upper teens, elevated to critical fire weather conditions will be unlikely. The aforementioned low will be absorbed into a larger scale trough cruising the Canada/CONUS border, keeping dry air in place on Sunday, along with low-end breezy conditions.
