The light precipitation has arrived, and it’s doing just about what we expected. Flakes or ice pellets in the air, sticking lightly in some spots, but not in others. As I mentioned in the first couple sentences of last night’s post, it may end up being just a “talker” as we say in the business. I first saw the term “conversational snow” a few months ago and I’ve decided it’s a perfect weather phrase. It means enough snow for folks to notice and admire, but not enough to have a significant effect on roads or your life. Just enough to blare the Christmas music in your car as the flurries zip by at 65 mph while you spread butter on the bagel, fix your hair, and sip your coffee.
I have white ground here at home, that’s just since 7am. Many areas in the main part of the metro area have seen nothing sticking to the ground though. There has been less than expected up in Clark county. Looks like 1/2″ at best so far north of Vancouver. I still think the Battle Ground to Amboy areas have the best chance of getting 1″ or so before it’s over. Also watch out for freezing rain in a few protected valleys in the Coast Range or Cascade foothills. It’s real straightforward; if your road is wet, it’s not going to freeze now. But if it is snow-covered a layer of ice may form over the top of that before 10am if your local temperature is below freezing.
Models have clearly shown a back edge to the solid precipitation and that may be what’s coming over the Coast Range right now.
Big Picture: As expected, we escaped a significant snowfall and by 9am the upper atmosphere will warm too much to support snow anyway. Then it’s on to gusty southwest wind this afternoon. Probably the strongest southerly wind we’ve seen in about 3 weeks. Maybe 30-35 mph gusts.
