Snoqualmie Summit Forecast Includes Fog and Snow Flurries

At Snoqualmie Summit, this week started with a mix of freezing fog, light rain, and snow showers. Today's (Monday) temperatures will climb in the upper 30s before dropping to the mid-20s tonight. The fog will likely hang around into Tuesday morning before another round of snow and rain arrives with another storm.

Tuesday evening, expect steady rain at the pass, with temperatures in the mid-30s and up to three-quarters of an inch of rain possible. Drivers heading over Snoqualmie Pass should be ready for changing road conditions from wet pavement one moment to icy patches the next.

Tuesday night, the rain and snow hit again, but higher temps should keep it from sticking. The roads will be slushy but slick.

Blue Mountains Getting Snow and Fog

Farther east, the Blue Mountains are also expecting light snow and fog early this week, part of the same system bringing moisture across southern Washington. Winter travel season is here, and starting November 1st, chains and traction tires will be back in play.

Reminder, make sure you check WSDOT mountain pass reports before heading out, especially during evening hours when temperatures drop the fastest.
