Fine, I'll do what EC won't do and calculate the Humidex for ALL stations including those with temperatures UNDER 20C.

Here you go...

Temps already in the low 30s in Chilliwack as of 9:30am. Even see a 32C reading.

Soundings at 500mb (as per Seattle NWS) did suggest record breaking temps aloft.

Only 28C here, but humid. Gonna be gross later.

Okay, so it seems that they don't report the Humidex unless the ambient temperature is 20.0C or higher?

They never used to report the Humidex, either, unless the value was 29 or greater. I'm not sure when that changed, but I think it's not really accurate at values below that threshold.

Range of humidex: Degree of comfort

Less than 29: No discomfort
30 to 39: Some discomfort
40 to 45: Great discomfort; avoid exertion
Above 45: Dangerous; Heat stroke possible

Yeah, the KUIL sounding was pretty impressive.

In Fahrenheit, but here are the local observations from the NWS site.

Very interesting hourly progression of a record high temperature.

In that context, our house high last year during the heatwave was 39.8 on July 28, 2021. Location is North Burnaby just up the hill from the golf course. The hourly temperature progression was: low of 24.6; 25 degrees at 0710, 26 at 0830; 27 at 0850; 28 at 0910; 29 at 0930; 30 at 0940; 31 at 1000; 32 at 1010; 33 at 1020; 34 at 1100; 35 at 1120; 36 at 1230; 37 at 1250; 38 at 1320; 39 at 1430.

Our high yesterday was 30.3; based on the trend so far today (now 28.4 at 1050), we should see a temperature of around 35-36 here.

If im being honest, yesterday was a pretty run of the mill warm day. Humidity didnt seem to be much of an issue. This morning wasnt even bad inside the home. Meh. Today is spike day, then temps slowly dwindle away into the next troffy episode

[wetcoast91]

Temp still creeping up. 32.2 degrees. The snow will transition to rain soon.

I stand by my 37.8c at YXX

Edit: Long way to go. 4c ahead of yesterday..which puts Abby at ~36-37c later. I may have guessed too high

Cultus Lake the hot spot in BC at 34.6c at noon according to EC
