Update

Today's front was not all that eventful but it led to the formation of a long-lived convergence zone in southern Snohomish county. Moving forward, tomorrow will be cool and showery with highs in the lower 40's and lows in the 30's. Some places could see their first freeze. Some showers could enter the Puget Sound tmrw night, temps will be at their coldest at this time so some snow could mix in. Better chances for areas over 500 ft. Certainly not expecting any accumulation for areas below 1000 ft. Similar forecast for the Portland area. After that our attention turns to the bombcyclone. 

An area of low pressure will rapidly deepen as it moves closer to the coast. The low pressure could bottom down to below 950 millibars! The storm won't have major impacts for Western Washington but the strong pressure gradient will lead to the development of east winds. The foothills (North Bend, Enumclaw, etc) could see a period of strong winds beginning Tuesday evening. Gusts up to 60 mph wouldn't be out of the question for these areas. Parts of the coast could also seem some gusty winds up to 60 mph. The wind forecast will be heavily dependent on the position of the low pressure system so details will be ironed out as we get closer. Other than that and more mountain snow, I am not expecting any other major impacts.

This storm is certainly one of the more rare occurrences in this area and it would be a devastating blow it it tracked inland. Thankfully, this is not forecasted to happen and the storm will remain well offshore. But it is certainly interesting to see what our atmosphere is capable of producing!

Hope everyone had 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...
