...Synopsis... An amplifying mid-level ridge over the Four Corners region will support a large area of hot and dry conditions over much of the Intermountain West. On the northern periphery of the ridge, southwesterly flow aloft will increase ahead of a shortwave trough. This will allow a dry cold front to approach and stall over the northwestern Great Basin. Ahead of the front, very warm and dry conditions are expected. With the increased flow aloft, forecast guidance shows south-southwest surface winds increasing to around 15 mph with gusts to 20-25 mph. The stronger winds amid a very dry airmass will support minimum RH of 5-15%. With regional fuels very dry, elevated fire-weather conditions appear likely.
...Northern Rockies... To the northwest, the mid-level trough and remnant monsoon moisture may support isolated thunderstorm potential across the higher terrain of the northern Rockies. Some lightning is possible, though the highest storm chances are expected over western MT and northeastern ID where less receptive fuels are present. This suggests the threat for ignitions is modest and below 10% coverage for IsoDryT highlights.
