SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0118 AM CDT Sun Jul 27 2025 Valid 271200Z - 281200Z ...Synopsis... A mid-level trough will linger along the West Coast as upper ridging builds over the remainder of the CONUS today. Weak mid-level perturbations pivoting around the trough will traverse the Great Basin into the northern Rockies, providing enough upper support for both dry and breezy conditions across the central Rockies, and thunderstorm activity over parts of the Northern Great Basin into the Pacific Northwest. Across the central Rockies, sustained southwesterly surface winds may exceed 15 mph for several hours, amid 15 percent RH and dry fuels, warranting Elevated highlights. Across the northern Great Basin into the Pacific Northwest, the lifting of mid-level moisture will encourage high-based thunderstorm development by afternoon. Forecast soundings depict inverted-v profiles, suggesting that a combination of wet and dry thunderstorms are possible. With dry fuels in place, isolated dry thunderstorm highlights have been introduced. ..Squitieri.. 07/27/2025 ...Please see www.spc.noaa.gov/fire for graphic product... Read more
