Isolated to scattered thunderstorms are likely across much of the Interior into south-central and southwest Alaska, with showers and wet thunderstorms likely for northeast Alaska. Cooler temperatures and higher humidity are expected across northern Alaska and portions of southwest and south-central Alaska as upper-level troughs move over those areas. A cold front will likely move into portions of the Interior tonight, but warm and dry conditions should remain across most of the Interior into southwest Alaska before it arrives. Dry thunderstorms are possible in eastern Nevada into far southern Idaho, and isolated dry thunderstorms are possible in the northern Sierra and central Oregon into northeast Oregon and southeast Washington, including the potential for nocturnal thunderstorms. Dry and breezy conditions are also likely along and east of the southern Sierra into southern Nevada. Hot and dry conditions will continue in much of Texas and the ArkLaTex and from California extending north and east into the inland Pacific Northwest, northern Rockies, and western and northern Great Basin. Thunderstorms are expected across the Great Lakes and much of the Southeast near the coasts, with severe thunderstorms likely from the Northeast into the Mid-Atlantic.
