By 6:30pm, the storm was creating lightning and thunder over Hillsboro, Aloha and parts of Beaverton. Thanks to Aaron and Ryan for the pictures of the storm. With only about a dozen or so lightning strikes from this storm you guys really nailed the timing to get these bolts!
Here are some facts about the storm: cloud tops shot up to 25,000′ during the storm’s maximum strength – this was over Aloha. 25,000′ is a pretty good thunderstorm in the northwest but certainly tame compared to mid-west storms that have cloud tops in the 50,000-60,000′ range. Maximum rain rates in a very narrow core of the storm were about 1″ an hour.
The storm dropped hail off and on from Dundee all the way to the west hills and eventually on over to Clark County which caught just the eastern edge of this storm as it moved north toward St. Helens and died off.
There were no reports of damage. But if you were under the storm you probably have some stories to tell!
