Josh Classen's forecast: Nearing the end of the heatwave
![Edmonton skyline. Edmonton skyline.](/content/dam/ctvnews/en/images/2022/9/2/edmonton-skyline--1-6053542-1662142578527.jpg)
Two more days of 30 C heat and then some cooler air moves in. Temperatures looks like they'll be near 20 C for daytime highs by Friday/Saturday.
That's where our morning LOWs have been the past several days.
We'll talk about the smoke in a moment, but first let's deal with the heat for today and Tuesday.
Temperatures hit a record-setting 33.8 C on Sunday. That broke the old record of 32.8 C from 1945.
It's unlikely that we'll set any record highs today and/or Tuesday.
A lot will depend on how thick the smoke is, but even if it completely cleared out...I'm skeptical we could beat today's record of 34.5 C (set in 2006).
Tuesday's record high is 33.4 C (also from 2006). That one looks safe as well.
I think we'll get to the 31-34 C range today and the 29-32 C range Tuesday.
Today will be Edmonton's 7th consecutive day above 30 C. That ties the all-time record from 2021. (There are only two other years with five or more.)
There's about a 50/50 chance that we break that record tomorrow. Again, a lot will depend on the smoke situation.
And with that, let's get into the smoke forecast.
To be clear...smoke forecasting is MUCH more difficult and less reliable than cloud/precipitation/temperature forecasts.
The models DID indicate smoke would move into the Edmonton area for the weekend, but was off on the thickness (particularly for Saturday).
With that said, expect SOME variability in air quality through the coming days. However, it doesn't look like we'll get any better than a moderate risk and there may be times we're back into an extreme risk situation like Saturday.
Also, with smoke now present across much of B.C., Alberta and Saskathcewan...it's not even so much a matter of determining if the wind is coming at us from areas with fires. We're now trying to determine where exactly the thickest smoke is and whether or not the wind is coming from those areas AND/OR regions with fires.
Bottom line: the hazy conditions will persist for the foreseeable future with some days being a bit better and some days having thick smoke.
And...there's probably not going to be a lot of advance warning on when those changes will occur.
Thunderstorms are already developing in northwestern Alberta this morning and we'll see more of that through the day in that region.
We're not anticipating any thunderstorms in the Edmonton area today or Tuesday.
Wednesday would be our next-best chance to get some precipitation. There's a chance of showers in the morning and a risk of thunderstorms later in the day.
Thursday also has a very high probability of showers or periods of rain.
Two last notes: I'll write up a separate article detailing all the records from the past few days, so look for that on our website later today.
Also, I'm on an extended stretch of holidays starting Tuesday. This will be my last WxBlog until next week.
Here's the forecast for Edmonton and area:
