Hmm block?

Just as I expected. As soon as the SSW starts, we see a model shift. Looks like both are happening right now.

Nice and broad but we need that sucker to amplify. Build that bridge across the arctic. Looks like the west based -NAO is here to stay for a while so it could happen.

In the short and mid term though, there is absolutely no chance of that pacific jet shutting down.

Perhaps a 2006 storm cycle pattern? Both November and December had back to back damaging windstorms and heavy rain events.

Not surprised. Tomorrow morning looks quite wet, especially for northern sections of the lower mainland.

The amount of rain we got in the first three quarters of November 2006 was crazy. Mostly SW flow.

The next couple weeks look a lot more zonal.

Not sure about now, but at one point it was in the vicinity of between taxiway Bravo and Charlie.

Actually Bonerman that's B.S. it's between Bravo and Sierra.

Looks like I might get another 5cm of sloppy while I sleep snow.

Hmmm

I have a Facebook page too for BCStorms, but it doesn't have the same community type feel. I only post some model things sometimes but you can send messages. Usually someone from the forum sends me a Twitter message if the site is down, which hasn't had to happen too many times yet thankfully.

Yup. I got locked out of my account once due to a password issue, and Stuffy got it fixed for me right away after I sent him a message on Twitter. Thanks Stuff!

That said, I do think we should consider finding a backup source, since we may not all have Twitter and be able to message you.

That sounds conservative. I'm going with 5 - 10 for you, gut feeling.
I know burnaby mountain has elevation, but the biggest payoff to me will be those situations where the arctic front and the low dont quite meet up in time. These kinds of sloppy slushuations are kinda meh in my opinion. Itll melt in no time.

[Pomoman]

I’d be down with a good 10 cm. Like you said it will melt in a hurry once snow levels rise in the morning. But hey it’s snow.

Totally. Never going to say no to that. I just grew up in the caribou and okanagan and it spoiled me for life. I hope you get your just rewards for -> moving to a better spot tonight!

[Pomoman]

I’ve seen the flakes fly on 4 occasions so far and twice accumulated over 3cm. Fringe benefits seem to be my friend

Hopefully January brings us something other than 1 week of rain followed by 20 minutes of brightness a another week of rain. As a lifelong resident of the lower mainland I'm used to the rain but would take some clear and cold to make it feel like winter.
