An upper level wave tracked up from the Clearwater Mountains of Idaho towards the Seeley Lake area and initiated thunderstorms thanks to warmer than normal temperatures in the region. As these storms tracked over the Bitterroot and Clark Fork Valleys, they produced damaging winds and power outages. Also, a thunderstorm produced torrential rain and subsequent flash-flooding to Anaconda in southwestern Montana.
