SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0451 PM CDT Tue Jun 17 2025 Valid 191200Z - 251200Z ...Day 3-4/Thursday-Friday... An upper-level trough will begin to enter the Pacific Northwest Day 3/Thursday while upper-level ridging shifts eastward into the Plains. Increased mid-level flow atop a dry/well-mixed boundary layer will bring an expansive fire weather threat much of the Great Basin and Colorado Plateau in the form of breezy southwest winds and low relative humidity. A mid-level wind maxima rounding the southern periphery of an upper-level low then pushing into the Pacific Northwest will support even stronger southwest winds of 20-30 mph (locally higher in favored downslope regions) across much of central/southern Utah, northern Arizona and far western Colorado as well as northwestern Nevada where fuels have become increasingly supportive of wildfire spread. 70 percent probability of Critical fire weather conditions have been maintained and expanded within these areas. ...Day 5-8/Saturday-Tuesday... The warm, dry and breezy conditions supportive of wildfire growth in dry fuels will shift southeastward towards the upper Colorado River Basin and northern Arizona by the weekend. Magnitude of winds will wane by early next week as mid-level flow relaxes and shifts northeastward. However, the combination of increasingly dry fuels, drought and lack of rainfall will support an ongoing fire weather threat through Day 8/Tuesday across much of southeastern Utah, northern Arizona and far western Colorado. ...California Central Valley... Dry, post-frontal northerly flow along with low relative humidity and cured grasses will support at least an Elevated fire weather threat on Day 5/Saturday across the Central Valley. ..Williams.. 06/17/2025 ...Please see www.spc.noaa.gov/fire for graphic product...
