PORTLAND, Ore. – Some serious Pacific Northwest rain is on the way Thursday. Forecasters say the past couple days of brief showers, grey skies and misting were all leading up to this precipitation storm.

The National Weather Service in Portland said a wet, cold front moving southward across western Oregon is leading a cool upper level trough through the area.

This means snow levels will lower near the Cascade passes and yes, you guessed it, lots of rain will fall in the metro area and Willamette Valley.

In the Cascades, the snow levels will lower around 4,000 to 5,000 feet Thursday night. These elevations will accumulate a few inches of snow overnight.

Forecasters say there might even be thunderstorms.

The weather isn’t going to change anytime soon, so be sure to grab a rain jacket or umbrella before you leave home.

“Impressive rainfall totals” will fall through Saturday, the National Weather Service said.

Another system behind the front will eventually push the wet weather south to northern California.

“By the time that occurs, most of the Willamette Valley will have seen 0.50 to 1.00 inch of rain, with some spots over an inch,” forecasters say.

The northern Oregon coast will likely see 2 to 4 inches of rain.

Experts are concerned blocked storm drains could cause urban flooding, and that the heavy precipitation could cause landslides in the Eagle Creek Fire burn area.
