Two new large fires were reported, one each in Northern California and Rocky Mountain Areas which were contained. Four large fires reached containment, one each in Northern California, Eastern Great Basin, Northwest and Northern Rockies Areas. Very high to extreme fire indices were reported in Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington and Wyoming.
An upper level trough will continue to move east through the Eastern Great Basin, creating a dry westerly flow over the area. This will bring mostly sunny skies with isolated showers or thunderstorms over the mountains of Idaho and northern Utah. High temperatures will be 75 to 85, except 95 to 105 in southwest Utah. Monsoonal moisture will increase into the front range of Colorado and cooler air will filter into Wyoming behind a cold front that passed through. Colorado will become partly cloudy with isolated thunderstorms over the mountains and eastern portions of the state. Wyoming will be partly cloudy and breezy, with widely scattered afternoon showers and thunderstorms. High temperatures will be  75 to 85 in Wyoming and the 60's in the mountains. A weak high pressure will rebuild over the Pacific Northwest creating a warming and drying trend.  West of the Cascades will have morning clouds, with clearing in the afternoon. East of the Cascades will have sunny conditions. High temperatures will be in the upper 60's to mid 70's west of the Cascades, except for the interior of southwestern Oregon which will be in the mid 80's. East of the Cascades, high temperatures will be in the mid 70's to mid 80's.  An upper level trough will move out of Montana with diminishing clouds and showers. High temperatures will be in the lower to mid 60's in the mountains and in the mid 70's at lower elevations.
