Light snow. Temp 1.5°C, DP -0.6.
It's called clown range for a reason.

Day 5-10 so subject to change but rare to see this these days -- broad west based -NAO block suppressing the pacific jet.

Helps to lock in some modified arctic air in BC/AB meaning :flakey: potential for the south coast with systems to our south.

Maybe Gumps can take you out to sea to experience it?

In the short term... Get ready for some cold :raindrip: Wednesday through Friday! Low snow levels though... slush for Burnaby mountain and upper Westwood plateau? :think:

From what I remember of the teleconnections for the Jan 2020 cold snap it was mostly due to the tanked PNA... was there also an anomalous -NAO?

Also looks like home grown cold on the 18z... wasn't it a lobe of the PV coming out of Yukon/NWT in 2020?
