That was a fun 2 hours! Two clusters of thunderstorms did indeed form as our RPM showed (see previous post from midday). One passed from Beaverton down into Clackamas County, and another from the Coast Range out past McMinnville and Dundee. Appears to be about 110 cloud to ground (or ground to cloud) lightning strikes within the range of this map. It was a good weekend to work! My co-workers are still finishing up their honeymoons.
At 11pm the showers are almost all east of I-205 and 99E, mainly in the Cascade foothills.
