Thunder storms pushed through Oregon and Southwest Washington Monday morning, drenching the Portland area and sparking wildfires around Mt. Hood and in central Oregon.

Thunder and lightning were expected to continue east of the Cascades late Monday, according to KGW Chief Meteorologist Matt Zaffino.

Lightning strikes sparked at least 25 small wildfires in the Mt. Hood National forest Sunday night, according to officials with the Interagency Fire Center.

In central Oregon, a complex of at least four wildfires were first reported late Sunday and are burning on state-protected private land and federal forestlands. The fires, known as the Summit Springs Complex, range in size from a few trees to over 1200 acres. They're located over a large area between 10 and 20 miles north of Sisters, Ore.

"We've gotten more than 1,400 lightning strikes across the state in the last hour," KGW Meteorologist Dave Salesky said Monday morning.

In Portland, lightning struck a utility pole at SE 3rd and Stark Street. No one was hurt. Several thousand customers also lost power during the morning.

An unusually humid air mass and upper-level disturbance was behind the weather pattern, which was moving north.

Tuesday is expected to be drier and milder, but a winter-like storm is expected by Wednesday.

"Wednesday an unseasonable cold and wet system will arrive. It's going to feel like October," Salesky said. Highs might reach into the upper 60s, he predicted.

The colder and wet weather won't stay for long. This weekend high temperatures will return to the upper 80s and near 90 degrees, according to Salesky.

"It's going to be a roller coaster. Just grab hold and enjoy the ride," he said.
