That system seemed to usher in some warmer air, it's much milder -3.7C
It will get above freezing today!

There will be a new ECMWF Weeklies update today and new Seasonal data on Saturday! Currently all models are basically suggesting a normal or below normal Winter and Spring which is quite the difference from last year! I wonder if we will have a benign fire/smoke season this Summer?

My current thinking is nothing that happens before summer matters in terms of fires. 2-3 days of extreme heat is all you need.

Yeah given I had an inch of compacting in 3 hours I'm sure you did okay measuring at 6:30

That decrease from 6 to 2 at YVR in the middle of a snow event makes no sense whatsoever. They got at least 14 cm. (Hasn’t a poster in Richmond reported 15?)
It's called clown range for a reason.

so an average of 15 cm fell here, BUT, that is only an average since the wind created multiple depths of snow. So I took 4 different measurements and averaged them. Accuracy is in doubt...
