After Week of Sun and Frigid Temps, Snow Finally Creeps into Valley Weather Forecast

Update, December 10th, 6AMPM:

The National Weather Service canceled the Winter Weather Advisory it issued yesterday afternoon as the treat of snow in the Snoqualmie Valley has diminished.  Sorry kids.  No snow day.


It may have been 24 degrees in Seattle early Monday morning, but in the Snoqualmie Valley it was about 16-17 degrees – and some moisture is finally working its way into the local weather forecast.

Impending moisture is a sign that warmer air will eventually scour out the entrenched cold air, but weather forecasters say it will take about a day to get back to our typical gray and rainy winter weather.

Sorry kids and snow fans, just light snow (if any) is predicted. But according to the National Weather Service, the best chance for light accumulation (like 1-2 inches) through Tuesday is in the Cascade foothills.

Light snow is predicted to start moving onshore and work its way east Monday morning.  According to weather models, light scattered showers could coat the Snoqualmie Valley with around an inch of snow by this evening.  Then overnight Monday into Tuesday morning another inch might fall.  Key word, though?  MIGHT.

There’s also a chance of freezing rain before a switch to straight rain by Wednesday.  None of the precipitation is predicted to be heavy, but even a little snow, coupled by freezing rain, can mess with traffic and local roads.

And, as witnessed in the past, the Snoqualmie Valley can have its own micro-climate – making our local weather sometimes unpredictable.

So just a quick heads up that some light snow is in our weather forecast Monday, December 9th, and Tuesday, December 10th, along with possible freezing rain.  Temperatures aren’t predicted to moderate to above freezing (just mid 30’s) until Tuesday afternoon.

By Wednesday, it’s back to 40 and rain.  So one more day of cold temperatures, along with a possible shot of snow, as we transition back to our normal winter-like weather.

Enjoy your last day of our week-long deep freeze!
