SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1240 AM CDT Sat Jul 19 2025 Valid 201200Z - 211200Z ...Synopsis... The upper-level pattern on Sunday will be similar to Saturday. However, stronger mid-level flow may nudge southward as the upper trough amplifies through the period in the Northwest. Surface troughing will develop in the northern High Plains. ...Northern Great Basin... Another day of elevated fire weather can be expected. With the stronger mid-level winds extending more to the south, greater spatial coverage of at least briefly 20+ mph winds may occur. Overall, however, 15-20 mph winds will be most common. RH of 10-20% will be possible in Nevada while Idaho will more likely see 15-20% by the afternoon. Model guidance does show some potential for high cloud cover which could also limit the duration of critical conditions. Ensemble guidance shows low probability of sustained critical conditions likely on account of those uncertainties. ..Wendt.. 07/19/2025 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1238 AM CDT Sat Jul 19 2025 Valid 191200Z - 201200Z ...Synopsis... Upper-level ridging will persist across much of the southern half of the U.S. today. A weak upper-level low will be positioned over southern California into northern Baja. A belt of stronger mid-level winds will exist across the northern tier states with a low-amplitude shortwave trough moving through the Northwest. A surface trough will deepen in the lee of the northern Rockies. ...Columbia Basin into the northern Great Basin... Offshore high pressure and the deepening trough to the east will promote modestly strong westerly winds across the Cascades. Winds in the Columbia Basin will reach 15-20 mph with perhaps higher speeds within some of the Cascade gaps. RH of 15-20% is possible by the afternoon. In the northern Great Basin, surface winds of 15-20 mph are possible with RH falling into the 10-20% range. Stronger winds are possible in the Snake River Plain as mid-level winds will be stronger and better aligned with the terrain. There, up to 25 mph winds will be possible for a short duration. ..Wendt.. 07/19/2025 ...Please see www.spc.noaa.gov/fire for graphic product... Read more
