The wider storm
A negatively tilted shortwave trough of lower pressure pushed across the northern Idaho Panhandle during the early afternoon hours. There was just enough sunshine ahead of the upper level disturbance for surface based thunderstorm development. Moderate amounts of low level shear combined with the low level energy and dynamics aloft spawned a few stronger thunderstorms the pushed northeastward across the northern portions of the Idaho Panhandle. One of these thunderstorms was a supercell that produced large hail and damaging winds.
Began near Copeland (48.8408, -116.4047).
