Both of these thunderstorms were related to a Low pressure system that was moving across the Pacific Northwest and northern Rockies mid-week. (See maps, etc. from previous blog post). A cold front associated with that Low was in the vicinity of the Idaho/Wyoming border, pretty much was a stationary front on Wednesday and then that front passed across the Tetons on Thursday evening. Most of the more intense thunderstorm activity was occurring near this front.
