As promised, Tuesday afternoon marked the arrival of a soggy weather system in Seattle--and tricky travel over the mountain passes! Spin outs and collisions occasionally resulted in highway detours near Stevens Pass, and after dark, traction tires were required at all of the Cascade crossings, including Snoqualmie. A WINTER WEATHER ADVISORY goes on to underscore the additional snow expected above 2,000' overnight and into Wednesday morning. Another 1 to 6" of late autumn snow should tally up nea

Our Christmas week is wrapping with a lingering frontal system, and the snow goes on for the mountains. The WINTER WEATHER ADVISORY in the Cascades has been extended until 4 a.m. Saturday to account for the lingering heavy snow over the high country, with an additional 6 to 12" possible by dawn. This is fabulous news for the ski parks, but not such fabulous news for pass travelers, as winter driving conditions are making for treacherous travel at times, including on Snoqualmie Pass. But how abou

Happy New Year! 2025 is certainly wrapping up on a foggy note. Dry December weather can be decent, but if it gets *too* calm and quiet, it leads to problems all its own...locally, that means fog (and worse, FREEZING fog) setting up in the natural bowl that is the Puget Sound Basin. You only need sustained winds of 7 to 8 mph to scour fog out of the way---the wind acts like the "spoon" to stir that pea soup out of the picture. Unfortunately, the winds in Olympia, Tacoma, and Seattle have been dea

What a mellow start to December! We've gone quiet, cloudy and cool, but other than a few stray sprinkles in the lowlands or flurries in the Cascades, we are precipitation-free for our Tuesday night. Overnight lows will drop into the 30s for most of the region, and pockets of freezing fog may result in a couple of slippery pockets for morning commuters by dawn. We'll keep the calm weather going into Wednesday, with the mainly cloudy/partly sunny skies again keeping us in the chilly middle 40s aro

Our October weekends have all been stormy, and this final weekend of the month will keep the trend alive. We'll once again be wet, windy and wave-y (big breakers at the ocean beaches), but this storm will have much cooler air filling in behind it...we'll see the snow level hovering in the higher passes for much of Saturday and Sunday. The big Pacific frontal system was on approach all day Thursday, clouding us up throughout the afternoon. We are in the warm sector of the storm, which made for a

Stormy skies are making their way back to the region later this week, with rain, wind, waves and mountain snow all on the menu. In the short-term, we'll enjoy dry and mild October weather for one more day before the storm takes hold. Our wimpy Wednesday disturbance is currently winding down. We pulled a few stray showers from it, mainly near the B.C. border and Olympic Peninsula. Otherwise, the skies turned a bit ominous mid-day on Wednesday near Seattle, but the dark clouds didn't drop much rai
