Afternoon relative humidity around 10-20 percent will overlap sustained westerly winds at 10-15 mph (locally higher). Some locally Critical conditions may persist for a couple of hours where terrain enhancements favor locally stronger winds in the Cascade Gaps. ...Dry Thunderstorms... The western shortwave will bring forcing for ascent across portions of northern Nevada into southern Idaho and eastern Wyoming.
