You may notice this post is tagged, cold, wet, wind, and storm. We could get it all.

First, Monday: Today will stay cold and dry. The latest NAM and GFS model runs agree that there is more chance for snow on the East coast, (coming off the Strait) than there is for Port Alberni. But there is still likely to be snow for both. Expect no more than 2cm this afternoon and through the evening in either place. Also expect it to get down to -5C or colder tonight as it did last night.

Tuesday: Cold no Snow

Wednesday/Thursday: Difficult to say could be nothing, could be dangerous. The models have been flip flopping about the events of Wednesday and Thursday and it has me, and every weather person I follow confused.

Scenarios, in order of likeliness based on what I’ve seen from the models and heard elsewhere.

#1: if the storm heads well south of us through Washington, then we will remain dry, and quite cold and there won’t be much to say.

#2: if the storm is not too far south, say it passes over the Olympics or through Puget Sound, then we could have huge snow storm potential.

#3: If the storm is anywhere north of the border, then we can expect possibly a big dump, followed by a quick change to rain with possibly some wind.

The models seem to be taking the storm south more often than, not, so I’m betting most on the first two options.

Here is what the GFS has for now: this will likely change.

The precipitation:

The temperature:

What is without doubt is that Friday the coast will have a major low push through down to 970mb. This will produce strong winds. It should all be rain by then, but if we end up still in the deep freeze on Wednesday and Thursday then Friday could be really really ugly.

Here’s the model for pressure… Look at that dip on Friday! (Saturday ain’t shabby either)

It looks like we won’t know all this for sure until we get within 24hrs of each event… Stayed tuned.
