SEATTLE — A chilly Monday morning beckons as an upper-level trough moves through the region, bringing with it showers and brisk winds. A Wind Advisory remains in effect for San Juan and Whatcom Counties until 2 p.m. due to ongoing Fraser River Outflow. As the day progresses, expect breezy conditions to calm slightly, transitioning into gusty weather later on. Initial showers are primarily affecting the South Sound area but are forecasted to diminish, allowing for clearer skies and increasing sunshine. High temperatures today are projected to reach the upper-50s to lower-60s.
Blewett Pass experienced snowfall overnight, prompting the Washington State Patrol to share images highlighting the wintery conditions. Although the roadway remains open with controlled traffic by flaggers, drivers are advised to anticipate reduced speeds and occasional delays due to maintenance efforts following previous fire activity in the area. White Pass Summit along US 12 also saw a mixture of snow and slush.
Looking ahead, tonight will bring clear skies and cooler temperatures, possibly dipping to frost levels, particularly away from waterfront areas. Tomorrow promises more clear conditions with highs settling in the lower-60s, a trend expected to continue into Wednesday.
Thursday may offer increased cloud cover along with a chance of light sprinkles, while Friday could see additional showers amidst cooler weather. The weekend forecast suggests a drier start on Saturday, but rain is anticipated to develop later in the day, resulting in a wet finish on Sunday with highs around the 50s.
Overall, despite the cooling temperatures and potential rain, the community can look forward to the beauty of changing seasons and a reminder that winter is just around the corner.
