December 2020 Forecasts and Discussions

Is everyone prepared for the last minute rug pull?

You need to go into this with low expectations... think cold rain!

So if it does manage to snow you will be pleasantly surprised.

If it cold Rainz, then expectations will have been met.

Cmon Nito think positive! Think incoming Low strengthens on the approach

As usual, the models are struggling even this close to the event.

I really don't think this would classify as a rug pull. Getting a bunch of snow with no arctic air is a real challenge here.

[PortKells]

The early returns on January are about as ugly as it gets. There's a lot riding on this upcoming system here.

ECMWF. 150-300m snow levels for Vancouver Island. Mix down to 200m in the LM. Low pressure much weaker...more of an open wave.

Sounds like a marginal window splat event. Windshield accumulations likely if you crank up the AC.

Sounds about right.

12z ECMWF still lookin’ good. Gotta like this trend in the models.

How is the snow map for the ecmwf represent a 150 meter snow level? Shows snow right down to sea level

6:16 AM PST Sunday 20 December 2020
Special weather statement in effect for:

Metro Vancouver - central including the City of Vancouver Burnaby and New Westminster
Metro Vancouver - North Shore including West Vancouver and North Vancouver
Metro Vancouver - northeast including Coquitlam and Maple Ridge
Metro Vancouver - southeast including Surrey and Langley
Metro Vancouver - southwest including Richmond and Delta
Heavy wet snow possible over higher elevations of southern Vancouver Island and the Lower Mainland on Monday.

A low pressure system crossing Washington state Monday will bring abundant moisture to southern sections of the south coast. Areas with the heaviest precipitation will see the heavy rain switch over to heavy wet snow above about 150 metres during the day. Mixed rain and snow is even possible at sea level.

Precipitation should not be as heavy for northern sections of Vancouver so the snow level will likely be above 200 metres. Snowfall accumulations are uncertain at this time.

Nito's back in business..just wait till the models flip in our favour again>it's the flip flop game..well known if you track the models.

Look at upper level temps.

ECMWF snowfall maps always do snowfall amounts in marginal setups.
