Good day all, how was your snowfall? I see my predictions were spot on this time. I was starting to lose faith in myself.
A good helping of 15CM to 20Cm fell across the entire south coast. They system delivered with an overly fat abundance of powdery light snow.
Now onto more important things.
Friday night, into Saturday and possibly beyond is looking like a massive snowstorm potential of epic proportions.
The scene:
Very cold air still trapped in all of SW BC. System dropping out of the North and sliding down over BC.
Models overdoing the warm-up, almost guaranteed at this point. (If this system was coming out of the south west,then it would be more clear).
Ground temps are frozen very well, river temps, and water body temps are at or below freezing. Excellent ice coverage on lakes and even the Fraser River. Another clear night tonight should lower temps pretty good and as cloud cover rolls in Friday hopefully, most likely the cold temps will be held in. Almost everything is on par for snow.
Now, the system is a bit warmer, so there may be some low level sea elevation that will see a transition at some point on Sunday. My feeling is this will NOT turn to rain at higher elevations, like Burnaby, Surrey, Fraser Valley. The usual suspects.
It will start as snow at sea level as well. Wet bulb will play a role.
The uncertain part of this is there is a high chance some areas will not transition to rain, and remain snow until Monday when the temps start to drop again and snow is even more likely. This will be riding the edge for sure. So many dynamics at play that are NOT normal in these situations.
My forecast, simplified. Friday Night and Saturday will see snow at all elevations. Heavy snow. Possible amounts 20CM lower elevations and to 40CM at higher elevations and inland going into Sunday. Now IF this turns out to be all snow, these amounts will verify easily over the 2.5 days. Then Monday comes with another storm that looks like it could run into Tuesday bringing another 20Cm or more!
It really is amazing the possibilities we are at right now. This could be the winter storm that puts that Victoria storm in second place if there is NO transition over the next few days. So keep that in mind. Again, "IF"
We all know there is a possibility of a bust, but at this point it could go wither way.
This coming week looks excellent for snow lovers. Some people could end up having a combined snow cover total of over 60CM! (Combined) <- Key word.
*This is a region wide event, in fact much of western BC will feel the impacts
EXCITING!
