As high pressure continues to build, hot and dry conditions will continue across the western CONUS away from the monsoon. A shortwave disturbance is likely to generate scattered wet and dry thunderstorm activity in the western Northern Rockies, central Idaho mountains, and into the eastern Great Basin. Gusty outflow winds will accompany the storms as they move over previously very dry terrain. Thunderstorms are possible in southern and central Oregon, and far northern California. Breezy conditions are anticipated in eastern Oregon, southwestern Idaho and northern Nevada. Monsoonal thunderstorms and showers will continue over the Southwest, mainly targeting the Four Corners region, with highest amounts of rainfall expected over southern Colorado and northern New Mexico. Isolated storms are possible in eastern and southern Nevada and in the Sierra Nevada as well. The southeastern corner of New Mexico, Texas, and portions of Louisiana will likely remain dry, breezy, and unstable. The possibility of widespread heavy rain will move into the central Great plains, Oklahoma, and the Lower Mississippi Valley, with lighter amounts expected across the Ohio Valley and into the Mid-Atlantic. Dry, breezy conditions will persist over much of the Southeast, northern Great Plains, and Upper Mississippi Valley.
