If you’ve been enjoying hints of spring lately, Oregon’s about to remind you who’s still in charge.

A powerful winter storm is rolling into the state, and it’s expected to dump serious snow across the Cascades just as many were starting to think winter was winding down.

According to reporting from OPB, a winter storm warning is now in effect from Wednesday morning through Thursday night, bringing heavy snow and strong winds to much of the Oregon Cascades and nearby foothills.

This isn’t just a light dusting either. Forecasters say some areas could see up to 20 inches of snow, especially across parts of Marion, Linn, and Lane counties. At times, snowfall rates could exceed an inch per hour between Wednesday afternoon and early Thursday morning, which is about as intense as it gets for mountain travel.

And it’s not just the snow. Winds could gust as high as 40 miles per hour, creating blowing snow and drastically reducing visibility across higher elevations.

Travel Could Get Rough Fast

If you’re planning to head over the mountains, you may want to rethink those plans.

Cascade passes across the state are expected to become difficult to navigate, with a combination of heavy snowfall, slick roads, and low visibility making travel potentially hazardous. Officials are urging people to delay travel if possible during the peak of the storm.

For those who absolutely have to make the drive, the National Weather Service recommends being fully prepared. That means carrying essentials like tire chains, extra warm clothing, blankets, water, a flashlight, jumper cables, and even a shovel in case you get stuck.

It’s one of those storms where being underprepared can quickly turn into a dangerous situation.

What About the Rest of Oregon?

If you’re not heading into the mountains, conditions will look very different.

Most lower elevations across Oregon will see steady rain through Wednesday and Thursday instead of snow. So while the valleys won’t be dealing with winter driving conditions, it’s still shaping up to be a wet and gloomy couple of days.

A Quick Return to Spring

The good news? This blast of winter won’t stick around for long.

Forecasters say warmer and drier weather is expected to return by Friday and continue into the weekend, offering a much-needed break after the storm passes through.

Still, if you’re hoping to squeeze in one last snowy adventure or planning a trip through the Cascades, this storm is a reminder that winter in Oregon doesn’t always follow the calendar.
