If things play out as currently modelled, the snow should start piling up.

Just need to get through that 1 last AR.

Although the little Miami River in Harrison Hot Springs doesn't flood or l've never heard of it flooding it's definitely up, nice view of Cheam peak from the lake today.

Look at that big block! I still think an arctic blast is coming to the PNW this winter. I really do but I think it will be after Christmas. I've had a really good feeling about January for a while. But I could be wrong. Like what someone suggested on here earlier, we could have an issue with the block ending up too far west and the polar lows ejecting the core of the cold over the water. Hope not but it seems to be a reoccurring theme this winter.

1981-82 progression.

That might be a top 10 day for them. It's not often you see Abby perform like that.

Totals from my manual gauge:

Tuesday: 12 mm
Wednesday: 83.9 mm
Thursday: 0.2 mm

Storm total: 96.1 mm

I believe this is my second biggest storm total since I moved to Mission.

The rain never got super heavy here. It was more like a very constant moderate rain. Obviously much worse out towards Hope and down in Skagit/Whatcom areas.

Same here. It was just a long duration moderate rain. I was actually surprised to have recorded 77.2mm at my station given the rain intensity. But it was actually lower than the 86.2mm recorded at YXX so either I was reading low or it was simply accurate. Since I've started keeping my station data records, I've only had three daily rainfalls of 60+mm. One of them was November 14th, 2021 where my station recorded 106mm. Another one was October 19th, 2024 where I had 75.6mm and then of course we have this most recent AR where I recorded 77.2mm for the day. Other than that, I usually top out just under 60mm during a top tier AR. It's just not common for AR's to take the path that bypasses the Olympic Mountains, which causes the rain shadow over Whatcom and the Fraser Valley regions. Thankfully, it's rare because the Sumas Prairie is highly vulnerable to flooding.

Snowfall amounts look great across the province. Looks like a good amount for the Lower Mainland in this run.

If anyone is wondering, don't really pay attention to these maps as they are macro scale and have terrain bleed which don't accurately predict the lowland snow at all.

As they say down south, fake snow.

Probably right. The forecast always show this, it shift east more as it gets closer, and usually the cold forecast is diluted to sometimes just an arctic fart. Dynamic weather is rarely something that ever pokes its head out around the coast now. Things are starting to line up to change things to the cool side though.

Places like Grouse have substituted the winter revenue with summer revenue more now. Opening of bike park and soon coast type ride down the mountain. There is only so much interest and revenue in two grizzly bears and a logger man show that is on repeat. Maybe Seymour needs to start some summer activities other than the easy one of pay parking.

Too cold out East for the West to be cold too. Throw it out.

Ya that's a good point Mr. Minion man although l do peak in at the Griz cam from time to time to see how they are.

Yah not allowed in our new climate rarely a coast to coast Arctic fart like decades ago.
