Another thing to be very fearful about flooding

There won't be any disastrous flooding.

This is not a flood-prone area in the spring. Now, if there was considerable snow to melt at the lowlands, then yes.

Any rain that falls will not be enough to cause flooding.

Unless it's a 1 in 100 year event that is. :shh:
It always snows in December in the Kootenays :clap:

The question is how warm will it get in the higher elevations and how long. 18z GFS abruptly breaks down ridge in week 2 and the CPC mentions some models showing a deamplification of the upper level pattern around 10-14 days out. There's some model uncertainty. I prefer cool, cloudy and slightly wet to have a slow melt situation instead of massive flooding that will come with an early heat wave.

Good news..recent model runs have that ridge breaking down much sooner. Looks like a 4 or 5 day dry stretch, breaking down around the 11th. Love the variable weather pattern we seem to be in.

Looks like it should be an interesting afternoon in weather. Some heavy showers on the radar and a special weather statement is up for winds!
Why not try cycling to work, grocery store, anywhere!

Ya some orange and red showing on the radar in SW Washington. Will it reach us up here? It looks like the brunt of the action is south of the border. Some rain shadowing occuring too. Here in Coquitlam its been in a dry pocket for a couple of hours after the Initial wave. It looked brighter like it was maybe gonna clear up.
