snow_wizard Posted February 18, 2018 Report Share Posted February 18, 2018 You were spot on when you said late February Arctic Blast are rarely dry! Looks like there's going to be numerous chances of snow this coming week for everybody! Indeed. I think it's at least 80% of late season cold events that have decent snowfall. Maybe higher. 1 Quote Death To Warm Anomalies!

TT-SEA Posted February 18, 2018 Report Share Posted February 18, 2018 I seriously wonder if the models will ever be good enough to accurately depict situations like this. I think the Olympics make it nearly impossible. A trajectory difference of just a couple of degrees can make the difference between no snow and several inches. Insanely difficult here. When you head westbound into Bellevue on I-90 and come down the hill towards 405... the Olympics look like a small bump on the horizon. It always amazes me how much they profoundly affect the weather in Seattle and Bellevue. I understand why the mountains play a role in North Bend... but you would never imagine mountains that appear so far off in the distance would block so much precipitation and be directly responsible for so many c-zones.

My comment was really directed at the ICON model showing temperatures that would not support much accumulating snow at the light to moderate rates depicted. I guess on a closer look it is showing around an inch for most of Snohomish county through Sunday which would be realistic given the temperatures shown I suppose.
