Initial attack activity was moderate nationally. Six new large fires were reported, three in the Northern Rockies Areas, two in the Eastern Great Basin Area and one in the Northwest Area. Seven large fires were contained, three in the Southwest Area, and two each in the Northwest and southern Areas. Very high to extreme fire indices were reported in Alaska, Arizona, California, Idaho, Kansas, Minnesota, Montana, Nebraska, Nevada, New Mexico, Oregon, and Washington.
Thunderstorm activity will continue to be on the decline today as a trough of low pressure approaches the Pacific Northwest. Isolated mixed wet and dry thunderstorms will develop again today over northeastern Washington, the extreme northern Idaho panhandle, and the northwestern Montana region. Elsewhere, thunderstorms will remain wet and shift eastward with activity over Montana, Wyoming and the Southwest. The Northwest, Northern Rockies and the Great Basin will be gradually cooling and relative humidity will rise in many locations; the exception being on the Oregon coast where offshore flow will result in drier conditions and poor relative humidity recoveries overnight. The upper level high pressure ridge over Alaska will hold strong for continued dry weather and record temperatures.
