SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0416 PM CDT Sat Jul 19 2025 Valid 211200Z - 271200Z A positive-tilt mid/upper-level trough, with enhanced mid-level flow along it's base, is forecast to remain across the Pacific Northwest Day 3/Monday. Thereafter, the trough is forecast to eject across the northern Rockies and into Canada through midweek. Meanwhile, a portion of the trough is forecast to become cutoff off the California coast Day 5/Wednesday through perhaps Day 7/Friday before ejecting northeastward, with a large-scale trough returning across the Western United States next weekend. ...Day 3/Monday - Day 4/Tuesday: Wind/RH... Mid-level winds are forecast to increase over the northern Great Basin Day 3/Monday as the aforementioned trough impinges on the area. A rather broad area of elevated fire weather conditions are likely, with critical fire weather conditions most likely across portions of the Snake River Plain in Idaho, along the Nevada, Oregon, and Idaho border, and across western/northwestern Nevada and adjacent portions of California where wind speeds are forecast to be strongest. Though, at this time, critical fire weather conditions appear too brief/spotty to introduce greater probabilities. Dry and breezy conditions are forecast to continue Day 4/Tuesday across much of the Great Basin. Though, relaxing mid-level winds and reduced surface pressure gradients should limit widespread fire weather concerns. ...Day 3/Monday - Day 4/Tuesday and Day 6/Thursday - Day 8/Saturday : Dry Thunderstorms... Dry thunderstorms are possible Day 3/Monday into Day 4/Tuesday across portions of the northern Great Basin, Northwest, and northern Rockies, as increasing moisture associated with the aforementioned trough overspreads the area. While forecast guidance suggests precipitable water values may be relatively high (0.8 - 1+ inch), somewhat fast-moving storm motions and critically receptive fuels suggest a mix of wet/dry modes. At this time, uncertainty remains too large to introduce probabilities for dry thunderstorms. Dry thunderstorm potential may return across the western United States by Day 6/Thursday as the aforementioned cutoff low begins to move onshore. Though, at this time, forecast guidance differs on the timing/evolution of the low, which reduces confidence in timing and coverage of dry thunderstorms. ..Elliott.. 07/19/2025 ...Please see www.spc.noaa.gov/fire for graphic product...

At this time, uncertainty remains too large to introduce probabilities for dry thunderstorms. Dry thunderstorm potential may return across the western United States by Day 6/Thursday as the aforementioned cutoff low begins to move onshore. Though, at this time, forecast guidance differs on the timing/evolution of the low, which reduces confidence in timing and coverage of dry thunderstorms. ..Elliott.. 07/19/2025 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0416 PM CDT Sat Jul 19 2025 Valid 211200Z - 271200Z A positive-tilt mid/upper-level trough, with enhanced mid-level flow along it's base, is forecast to remain across the Pacific Northwest Day 3/Monday. Thereafter, the trough is forecast to eject across the northern Rockies and into Canada through midweek. Meanwhile, a portion of the trough is forecast to become cutoff off the California coast Day 5/Wednesday through perhaps Day 7/Friday before ejecting northeastward, with a large-scale trough returning across the Western United States next weekend. ...Day 3/Monday - Day 4/Tuesday: Wind/RH... Mid-level winds are forecast to increase over the northern Great Basin Day 3/Monday as the aforementioned trough impinges on the area. A rather broad area of elevated fire weather conditions are likely, with critical fire weather conditions most likely across portions of the Snake River Plain in Idaho, along the Nevada, Oregon, and Idaho border, and across western/northwestern Nevada and adjacent portions of California where wind speeds are forecast to be strongest. Though, at this time, critical fire weather conditions appear too brief/spotty to introduce greater probabilities. Dry and breezy conditions are forecast to continue Day 4/Tuesday across much of the Great Basin. Though, relaxing mid-level winds and reduced surface pressure gradients should limit widespread fire weather concerns. ...Day 3/Monday - Day 4/Tuesday and Day 6/Thursday - Day 8/Saturday : Dry Thunderstorms... Dry thunderstorms are possible Day 3/Monday into Day 4/Tuesday across portions of the northern Great Basin, Northwest, and northern Rockies, as increasing moisture associated with the aforementioned trough overspreads the area. While forecast guidance suggests precipitable water values may be relatively high (0.8 - 1+ inch), somewhat fast-moving storm motions and critically receptive fuels suggest a mix of wet/dry modes. At this time, uncertainty remains too large to introduce probabilities for dry thunderstorms. Dry thunderstorm potential may return across the western United States by Day 6/Thursday as the aforementioned cutoff low begins to move onshore.
