A compact upper trough will exit the Great Basin region this afternoon, traversing the High Plains and moving over the Upper Midwest in the late evening. A surface low will develop northeastward to the Great Lakes region and send a cold front southward through the southern Plains. An amplifying upper ridge over the eastern Pacific will promote warm and dry conditions across the Interior West, though much lighter winds (compared to previous days) will bring some relief to the fire environment. However, very dry fuels will continue to support Elevated fire concerns. ...Four Corners, southern Colorado Rockies and adjacent High Plains... As the upper trough and attendant surface low exit the region, surface troughing over the Four Corners and Colorado Plateau will support westerly winds up to 15 mph amid 10-15% RH. In the wake of a cold front, veering north-easterly 15-20 mph winds (gusts up to 30 mph) and RH values of 10-20% will spread across portions of the southern Rockies and adjacent High Plains. Elevated highlights have been maintained to account for these conditions where dry fuels exist. Latest forecast guidance also shows elevated wind/RH spreading farther east over portions of the central High Plains. However, recent rainfall and resultant sub-critical fuels preclude an expansion of highlights. Briefly critical conditions are possible across northern NM and portions of the CO Plains and gap-flow regions, but the localized extent and limited duration of stronger winds precludes critical highlights. ...Sacramento Valley... Current northerly winds of 10-15 mph will persist with very poor humidity recoveries (RH values of 20-30% overnight). As an upper ridge over the eastern Pacific pushes the upper trough eastward, northwesterly flow aloft will weaken and shift more westerly. Northerly surface winds will gradually decrease throughout the afternoon, however fire concerns remain as 10-15% RH lingers into the evening. An extended burning period and dry fine fuels support Elevated highlights within the Valley and adjacent foothills. ..Elizalde-Garcia.. 06/11/2026 ...Please see www.spc.noaa.gov/fire for graphic product... $$
