DISCUSSION

Issued at 940 PM MDT Tue Sep 8 2026

High pressure to our east flattens as a trough moves across the northern high plains and southern Canada. The only real significant change for us will be flow shifting from southwesterly to more north through northwesterly. Models continue to indicate drier air across the area through Thursday and with no disturbances, anticipate dry conditions for the entire CWA. Warm temperatures will continue as highs remain anywhere from 5 to 10 degrees above more seasonal values.

Some deeper mixing will bring some gusty winds to the surface today and tomorrow while humidities hover around 10 to 15%. However, the gusty winds will be marginal at best. So despite these values being close to critical fire weather thresholds, only localized critical fire weather conditions are expected mainly for the Four Corners region.

As far as our next moisture push, models continue to highlight PWATs reaching upwards of 150% of normal for the Friday afternoon onwards. This remains dependent on the evolution and track of an area of low pressure/trough off the PacNW coast and the resultant moisture advection thanks to a more southerly wind flow. If this pans out, we could see some showers and a few storms. Time will tell, however, so keep an eye on the latest forecast if you have any big weekend plans.
