A cold front brought the colder and windy weather yesterday and now a cut-off low will live in the Pacific Northwest for the remainder of the workweek. Disturbances will wrap around the low bringing shower activity through early Friday with breaks in the rain and clouds at times. A break from the rain with some sunshine this morning before a disturbance brings increasing showers activity late this morning through this evening. Snow levels start around 2,500 feet this morning and will be climbing through the day up to 3,500/4,000 feet. Another break from the showers overnight into tomorrow morning with showers returning late Thursday through early Friday.
In heavy showers, especially over the Cascades passes, visibility may be low at times. Also be prepared for slushy, slick and icy roads especially over the higher terrain and east of the Cascades. Showers can produce gusty winds and small hail. Winds won’t be as strong as yesterday, but still breezy, strongest wind gust yesterday was 55 mph at Long Prairie, just inland from the coast. Through Friday morning be prepared for wintry travel.
Now to the holiday weekend: The good news, it will be warmer, the bad news for outdoor activities, the chance for showers persists. The cut-off low will open up and allow waves of energy to slide down the backside and bring us a chance for isolated afternoon thundershowers east of the Cascades on Saturday. Chance for region-wide solated light showers possible Sunday and most of Memorial Day will be pleasant with increasing clouds and showers moving in Monday evening with rain on Tuesday. This weekend we will also be warmer with highs back in the low to mid-70s west side and mid-60s on the east side. Shower activity will not cause events to be a wash-out, but you may want to bring the umbrella.
