Friday Night Update

The much talked about potential for lowland snow is finally here and we are in the range where we can talk about specifics.

Tonight, a cold front is crossing the area, evident in satellite imagery.

 Behind this cold front is much colder air which will filter into the area tonight. Temps are sitting in the upper 40's currently in much of the Puget Sound, by about 2 AM, much of the area will be in the 30's and a gradual cool down will continue. At this time there are several chances for lowland snow, but accumulations will be spotty as the system is more showery in nature and not organized. 

There will be several areas with a heightened potential for lowland snow and I will point it out on this little graphic.

 Zone 1 is in Snohomish county and has a heightened potential for snow due to the convergence zone setting up over there tonight and into tomorrow. There is a chance this extends southwards briefly so some of northern King county could also see some snow. I expect about 1-3 inches with the CZ tmrw.

Zone 2 is Whatcom county and it has been area that has been highlighted on the models for snow. I expect 3-6 inches through Tuesday in this area.

Zone 3 is the Port Angeles area as the Olympics could enhance precipitation throughout this event. 4-12 inches for this area.

Zone 4 is the southern Puget Sound. Models have shown showered training over the area and we could see enhanced snow totals in this area. I am going with 2-6 inches with more possible closer to the foothills.


The central sound may not do as well with this event due to shadowing. Currently only expecting an inch or two for most of the central sound. 

This will be followed by very cold temperatures for much of the area. Temps will struggle to make it out of the lower 30's for basically the rest of the week, with lows in the lower 20's. Some areas with snow cover could make it into the teens. 

In the longer term, temps look to stay cold with more chances for lowland snow. 

Have a good night!!

Widespread Lowland Snow Incoming!!

 Well it is going to be an interesting 48 hours coming up. We will have snow, ice, sleet, rain, wind, basically everything on the weather bingo card in the next 2 days.  A strong and moist Pacific system will move into the area tomorrow evening, spreading precipitation into a very cold and dry air mass. A ripe set up for a snowstorm in the PNW.  Current satellite imagery shows moisture moving into Oregon.  This moisture will spread north and with the cold temperatures in place, it will bring wintry weather to the lowlands of Oregon and Washington. Winter and ice storm warnings are out for Portland and the Willamete valley. This storm will work effectively to scour out cold air in the upper levels so I expect precipitation type to quickly transition to freezing rain and sleet south of Salem. However, upper levels should stay just cold enough for precipitation to remain snow north of Wilsonville.  The low will pull east winds out of the gorge, keeping things very ...

Evening Update

 We are very close to tonight's snow potential and models still have no idea what will happen. Looking at Sattelite imagery, the low pressure we have been tracking looks to be a bit north of Hoquiam. How north this low goes will determine which area gets the most moisture. Earlier this area looked to be King County and the Central Sound, but now this area may have shifted a bit northwest. Northern King County and the Kitsap peninsula.  As I said earlier, this looks to be a bit more widespread in terms of moisture, but temps look to be more marginal so elevation will definitely aid with snow. Looking at the graphic below, the area circled in blue will have the most access to moisture tonight. In this area, places above 500 feet should see 2-8 inches of snow. Below that, 1-3 inches of snow seems likely. Another wildcard going into tonight is the deformation band as the low passes to the south of us, the models are struggling to nail that feature but if it does form then areas un...
