Hmmm..looks like the Similkameens is in the ground zero zone

Weather doesnt look good for the interior this weekend. Chance of T-storms in many locales..look to be mostly dry lightning with that wimpy quasi stationary Low

Why is there still a heat warning for Abbotsford and Chilliwack? Seems a little unnecessary now...

Not saying I agree but the explanation is in the warning. I assume it has to do with the deaths earlier in the week and just wanting people to check with elderly to make sure they are okay

“
In collaboration with BC Health Authorities, MSC has decided to continue the Heat Alert until a sufficient period of cooling has been observed. It is recognized that daytime temperatures may not meet published Heat Alert criteria.”

Still a week+ out but we are seeing signs in the models of the 4CH wanting to surge northward again towards next weekend

Can you please define 4CH, I can't for the life of me figure out what that means.

4 corners high, which is usually centered over the intersection of 4 states (Utah, Colorado, Arizona, New Mexico). It moves around a bit though and that combined with how strong it gets can really affect how hot it gets up here. It forms every summer and pulses and moves around a bit.

Well here it is Cst. Goose, Hounderdog as promised l drove by the volunteer Chilliwack weather station and snapped a photo.
Luckily no neighbours called the cops on me. it's next to Chehalis park in south Sardis.
excellent location all grass around the Stevenson screen. Maybe it can be moved to the weather station photos thread.

Nice job Mr Sardine!! Nice!

Ah the old 4CH, yeah l've heard reference to it over the years, But if l'm correct Mr. M it can bring our normal hot temps also can it send moisture eventually northwards?

No problem the things we do for the love of weather.

Some interesting reading from a weather blog:

From unprecedented heat to unprecedented wildfires. This satellite image was captured just several hours after the one posted in Wednesday’s blog. Smoke (grey-brown) can be seen along with massive pyrocumulonimbus clouds (white). The extreme dryness and heat, combined with an unstable atmosphere, led to extreme wildfire conditions on this day. Sadly, we have entered a new era of so-called “megafire” wildfires, wherein some fires become so intense they create their own weather, fueling themselves with strong winds that make them spread extremely rapidly. These fires are too intense and fast moving for wildfire crews to fight. Historical fire suppression (allowing build-up of fuels) and climate change have made these increasingly common. Fire weather expert Dr. Neil Lareau rightly described Wednesday’s pyroCu’s as “horrifying.” Very sadly, after three consecutive days shattering the nation’s all-time heat record, Lytton burned to the ground. It’s perhaps the most obvious victim of climate change to date.

Christopher Burt, a well-known weather extremes expert, said of this heatwave “The recent and ongoing heatwave in the Pacific Northwest (in both the U.S. and Canada) is not just another heat wave, it is the most anomalous extreme heat event ever observed on Earth since records began two centuries ago.” Climate change undoubtedly made the heatwave worse. The question of how much worse is a difficult one, and will be the subject of many studies to come.

I'm absolutely proud of my fellow British Columbians for stepping up in helping with the Lytton relief efforts that is or are being set up.
They are vowing to rebuild the town, but l really wonder how many will return.
You have to be concerned living in those other towns in the canyon with what happened to Lytton could happened to their town in an instant not to be a fear monger.
I'm surprised something like this didn't happen sooner we've seen hot dry conditions before in the canyon.

Phil keeps insisting the troughiness is right around the corner. He honestly had me fooled but he clearly doesn't know what he's talking about. Things are trending majorly hot again.
