Thunderstorms were developing around the Portland area, producing up to nickel-size hail.  As storms spread east into northeast Portland, a stronger storm developed, producing a fast-moving tornado starting around 9th Ave. and Wygant St. and ending around 38th Ave. and Shaver St.  The tornado brought down many tree limbs and a few large trees.  Minor damage was also done to a few roofs and a chimney.
