SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0101 AM CDT Tue Jul 07 2026 Valid 081200Z - 091200Z ...Synopsis... An upper-level trough will move into southwest Canada helping to flattening the ridge over the West and increasing west/southwest flow aloft across the northwestern US. The upper high will extend and shift westward over the southwestern US and off the southern California coast. A weak, Pacific cold front will move through the Northwest into the northern Great Basin. Westerly sustained winds of 12-20 mph with gusts of 20-30 mph amid minimum RH of 12-25% are likely across portions central/eastern Washington as the onshore pressure gradient remains enhanced. As the Pacific cold front moves southeast, winds will increase along and ahead of it across much of the Great Basin into the Four Corners. West-southwest sustained winds of 12-20 mph with gusts of 20-30 mph amid minimum RH of 5-15% are expected across this area. These dry and breezy conditions will be following multiple days of lightning across portions of the Great Basin, with holdovers likely to emerge. Isolated to scattered mixed wet/dry thunderstorms are likely from northeast Nevada/southern Idaho extending east-southeast to the West Slope. This will be on the southern/western periphery of the residual mid-level moisture that has tracked over the Intermountain West the past few days. Fuels remain near to record dry across portions of Utah and Colorado, and multiple large wildfires remain very active, with a history of pyroCb development in similar environments. ..Nauslar.. 07/07/2026 ...Please see www.spc.noaa.gov/fire for graphic product...
