scattered thunderstorms and showers today as a shortwave moves
through the area. Stronger storms will remain closer to the

Idaho tonight. Storms will be capable of outflows up to 50 mph,
small hail, and locally moderate/heavy rainfall. CAPE is

slip through the region on Thursday as an upper trough tracks
