We will have some off-and-on rain shower activity out there this evening into tonight, though the amounts won’t be all that heavy. By morning, low temperatures will be in the 40s in the lowlands so these milder temperatures prevent any issues with frost.
However east of the Cascades, as rain moves through, temperatures will get just below freezing in parts of Chelan and Douglas counties, so a Winter Weather Advisory is in effect there for the chance for more freezing rain to glaze road surfaces.
Rain will be around through the day Saturday in the lowlands and our attention turns to an area of low pressure offshore that will move near to our coast or possibly inland Saturday night and early Sunday. A high wind event looks unlikely and there are presently no wind advisories in effect, but it’ll be breezy mainly during the overnight and early morning hours of Sunday. Most lowland spots will have wind gusts in the 25-35mph range, but some stronger gusts are likely at the coast and northern waters. All-in-all, this is a pretty typical windy weather system for this time of year, but those who still have outdoor decorations that could blow away easily should secure them or take them down by Saturday night.
Also, it is our high astronomical (or “king tide”) period for this month. A Coastal Flood Warning is in effect for the Pacific beaches where up to three feet of additional high water is possible either side of high tide on Saturday and Sunday midday. This is a little higher than we’d otherwise expect because of the subtle “tug” upward of atmospheric low pressure in place. Inland, a Coastal Flood Advisory is in effect for Saturday for the inland waters, including most of Puget Sound. This will be high water level of more typical levels for a “king tide” period, meaning up to two feet of additional water rise is possible around morning highest tide. Some low-lying roads and waterside parking lots could see some inundation for a time.
Through the weekend, snow levels in the mountains will be above 5,000 feet Saturday dropping to 4,000 feet Sunday. So for Snoqualmie Pass, we’re looking at mainly rain.
After a relative “break” early Monday, more active weather comes our way by late Monday through Wednesday. The flow aloft shifts northwesterly early next week, bringing in colder air aloft. This will mean a much better shot at heavier mountain snow, especially around Tuesday. Cooler temperatures for all of us will be noticeable with lowland lows in the mid to upper 30s and highs in the 40s. Lowland snow doesn’t look too likely though we’ll monitor snow levels as they will be near or below 2,000 feet starting midweek.
