SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0121 AM CDT Sun Jun 07 2026 Valid 071200Z - 081200Z ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SOUTHWEST...GREAT BASIN...CENTRAL ROCKIES... ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTHERN IDAHO... ...Synopsis... A longwave mid-level trough will remain situated over the northwestern CONUS through the day on Sunday, with a shortwave trough moving across the northern Rockies. The attendant surface low and cold front will result in breezy conditions across portions of the Great Basin, southwestern CONUS, and northern Rockies with low RH values and critically dry fuels. ...Southwest, Great Basin, and Central Rockies... Ahead of the cold front, strong vertical mixing and a tight pressure gradient will result in gusty winds to 25-35 mph along with 5-15% RH. Poor overnight RH recovery across much of the area is expected to contribute to critically dry fuels across the region. For these reasons, a Critical area has been maintained in this outlook. Additionally, the cold front may provide enough lift and mid-level moisture for thunderstorm development across portions of Utah to central Wyoming. Given low precipitable water values and relatively fast storm motions, some Isolated Dry Thunder may occur in this region. ...Snake River Plain... Beneath the departing mid-level jet max, a relatively localized area of Critical conditions is expected in the Snake River Plain in Idaho colocated. Here, strong vertical mixing will result in winds of 25-35 mph along with 10-15% RH. Dry fuels in this region mean that a Critical area is warranted. ..Supinie.. 06/07/2026 ...Please see www.spc.noaa.gov/fire for graphic product...
