Valley snow forecast 2026: Where could Portland area see accumulation?

Snow is falling in the mountains, and now forecasters are suggesting it could make it all the way to the valley floor.

According to the National Weather Service in Portland, “confidence is increasing for several inches of accumulating snow with travel impacts somewhere in the lowlands” Wednesday night into Thursday morning.

But the question is, where will this potential snow potentially land and how much would potentially accumulate?

The snow, if it happens, is expected to arrive in a “narrow band,” the National Weather Service said, but it is still unclear where, or even if, that band will develop.

The agency put forth three options for where snow could accumulate, depending on where the low-pressure track ends up.

The first possibility would mean no snow on the ground for valley areas. The second could mean snow from Longview to Portland, and the third could mean snow further south from Salem through Eugene.

“If you have travel plans on Thursday,” said Tyler Kranz, a meteorologist with the National Weather Service in Portland, “please monitor the forecast closely over the coming days for updates as the details become clearer.”
