Strong Storm On Monday

 Apologies for not posting on Halloween, as I was quite busy, but I'm back now as we have more active weather to watch.

 Starting today, a series of weather systems will cross the area bringing lowland rain, mountain snow and wind. As I write this, a weak front is coming ashore but this will just be an appetizer for the bigger storm on Monday and that is what I will be talking about today.

Synopsis

On Monday, a strong area of low pressure, originating way off in the Pacific near Hawaii, will come ashore on the coast of Vancouver Island.


As this strong low moves over the interior B.C area, the pressure gradient will cause windy conditions in the western Washington area. Much uncertainty exists to the position and strength of the low, but some of the solutions have been concerning with very high wind gusts being portrayed, especially in areas near the strait of Juan De Fuca. The storm will also bring a strong frontal system to the south of the low pressure, affecting the area. Heavy rain coupled with strong winds will make for a difficult commute back home on Monday.

Winds

As mentioned above, the winds will be the most concerning factor of Monday's storm. Winds will start increasing midday around the Puget sound area and will continue to roar through the day as winds shift from southerly to westerly. Wind gusts around the strait of Juan De Fuca and the Islands look particularly damaging. Gusts up to 70 mph are possible for areas along the strait. Areas in the Puget sound will once again avoid the worst of the winds, but they could still pack punch with gusts pushing 40 mph in the metro area. Tree damage and widespread power outages are likely. Here is the European model's depiction of the winds tomorrow:

After the front passes, a strong convergence zone could form on the backside in Snohomish and northern King counties. 
Lastly, let's not forget about the mountain snow. By the time this storm passes, Snoqualmie and Stevens passes will receive 8-10 inches of fresh powder, with higher amounts due to the convergence zone. Certainly a positive start to the season for ski areas!
I will keep posting updates if necessary as we get closer to the event!
Have a great weekend!!

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 ...

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 abo...

Evening Update

Image
 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...
