The mix of snow and rain is expected to cause slick road conditions and potential travel delays during the Friday morning commute.

Why it matters

Snow and wintry weather can significantly impact morning commutes in the Pacific Northwest, leading to slower traffic, accidents, and public transit delays. This forecast highlights the need for residents to prepare for potential travel challenges and adjust their commute plans accordingly.

The details

According to meteorologists, the snow is expected to start Thursday night and continue into Friday morning, with a mix of rain and snow tapering to just rain by the afternoon.

  • The rain-snow mix is expected to taper to just rain by 2 p.m. on Friday.
