Isolated dry thunderstorms will remain the primary fire weather concern for Tuesday across the country. Latest forecast guidance hints that a deeply-mixed, but adequately buoyant, environment will remain in place across central AZ on the northern fringe of deeper monsoonal moisture. Forcing for ascent will be fairly weak and largely driven by orographic ascent along the Mogollon Rim. However, several deterministic CAM and recent HREF guidance hints at the potential for at least a few thunderstorms. This thermodynamic environment has yielded a mixture of wet and dry thunderstorms over the past 24 hours, so a similar combination appears probable for Tuesday. Fine fuels largely remain dry across the region, and recent lightning-caused fires hint that the fuel environment should support at least some fire starts. ...Pacific Northwest... A weak mid-level trough is forecast to move across the Pacific Northwest on Tuesday. While flow aloft will be fairly modest, the zonal flow over the Cascades and northern Sierra Nevada will likely induce a downslope flow regime within an antecedent dry environment with receptive fuels. Ensemble support was too limited to warrant additional highlights, but localized elevated fire weather conditions appear possible across far northwest NV, eastern OR, and southern WA Tuesday afternoon. ..Moore.. 08/11/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
