The first reports of light snow came in from Puyallup, Federal Way, Tacoma, Parkland, Lakewood, Maple Valley, Everett, Mukilteo and other locations Sunday morning.
By noon, snow flurries were reported in more locations, including downtown Seattle and many other Seattle neighborhoods.
Sunday morning's snow is courtesy of a weak system that developed offshore and moved inland overnight to our south. It is expected to move out by midday and none of the snow showers roaming around Sunday in the Puget Sound area were going to amount to much -- maybe 1/2-inch at best.
However, some models indicate perhaps light accumulations along the lines of 1-2 inches are possible today from Olympia south, so factor that in to your plans Sunday.
Meanwhile, arctic air will continue to funnel in from the Fraser River Valley, keeping temperatures in the mid 30s Sunday, except around 30 near Bellingham and Whatcom County.
Forecasting models are pretty consistent that it will be a dry but very cold night with lows in the mid-upper 20s. This is cold enough that places that did get a little moisture Sunday could be dealing with icy roads Monday morning as those wet roads freeze.
A second, stronger system comes in on Monday, however its impact remains uncertain for the greater Seattle area.
Most forecast models bring the system in well to our south into northern Oregon, focusing most of the snow potential there with the northern edges of the storm spreading snow as far north as Olympia. Areas to the north of Seattle will likely remain dry but just be very cold.
As for the area between Seattle and Olympia? Well, that's tricky.
One model has been adamant with this southerly track. However, another one has been fluctuating and at times brings the system in farther north -- far enough to paint about 1" of snow as far north as the Seattle Metro area Monday afternoon. That is a low chance now, but something we have to monitor.
Right now, we're keeping the "best odds" forecast with snow in Southwestern Washington -- maybe 1-3" depending on how much moisture makes it north. We're leaning dry but cold for Seattle Metro area, but with a very big asterisk.
For areas north of Seattle, you have pretty high chances of getting zero snow, but as a consolation prize, you'll get the cold north wind as this storm reenergizes the arctic outflow out of the Fraser Valley.
Highs on Monday will likely be upper 20s to near 30 north of Seattle, right around freezing in the Seattle metro area, and probably low 30s in Southwestern Washington.
So to recap: Everyone be on the lookout for icy roads Monday morning. Those of you in Olympia and points south, be prepared for potential snow on your commute home Monday. For Seattle-Tacoma Metro and points west and east, keep an eye to the forecasts and we'll let you know if that moisture looks like it's going to sneak farther north and if Monday's commute home will present any challenges. But as of right now, the Puget Sound area looks like it'll dodge the snow.
And if you're reading this from Portland or the Vancouver/Longview area, really keep an eye to forecasts as you have a much higher chance for accumulating snow during the day Monday.
Dry Out / Bitter Cold Monday Night
All the snow/moisture is gone by Monday night and we begin to clear up and really dive into the ice box, as that system will have brought in another wave of cold air. Lows will drop into the teens to low 20s. Of course that means any kind of moisture will be a very solid freeze on the roads for Tuesday morning.
Tuesday: Sunny and VERY Cold
Photographers -- grab your cameras. Tuesday will be an incredibly crisp late-fall day with plenty of sunshine but very cold temperatures. Highs will only be near 30 meaning most of the day will be in the 20s.
But the mountains should be out in full force. If you've been meaning lately to take a trip to the Space Needle or, say, Kerry Park, Tuesday is your day. Just bring the camera and a very heavy coat. (And send us any great pictures you get to our YouNews site. I'll post some in a future weather blog and we might use some on air.
Another chilly night Tuesday night
With clear skies, Tuesday night might end up colder than Monday night, with lows solidly down into the teens most areas, maybe 20 or so in Seattle with urban "heating".
Slow warm up
Long range models do gradually warm us up as we head toward Thanksgiving with highs then back into the 40s.
Stay warm out there!
