Josh Classen's forecast: Smoke lingers for a few more days
Wildfire smoke that blew into the Edmonton area from the northwest on Thursday looks like it could be stuck in the Edmonton area through the weekend.
That's a bit of a change from what I was thinking yesterday.
The modelling indicated the thickest smoke moving east of Edmonton overnight and this morning, but that just hasn't happened.
Air quality remains extremely bad in the Edmonton region as a bit of an inversion and low wind has trapped that smoke in place (it's also why we're dealing with the fog early this morning).
Smoke HAS moved into eastern and southeastern Alberta, it just hasn't cleared out of the Edmonton region.
Before going any further...let me stress: smoke forecasting is VERY DIFFICULT (for a wide number of reasons), especially over timeframes longer than a day or two.
So...there's definitely some uncertainty with this outlook, but here goes:
With a more easterly/southeasterly wind direction in the lower and mid-levels of the atmosphere...it looks unlikely that the smoke will move out today (the wind direction actually doesn't change much between now and the end of Saturday).
Given the fact that there's a chance of a shower or thunderstorm tonight and some scattered showers possible Friday, there IS a chance that precipitation could "wash out" some of the smoke before the weekend, especially since this seems to mostly be smoke near the surface.
(If it was high-level smoke, precipitation can sometimes mix that down to the lower levels and increase surface-based smoke.)
I don't think there'll be enough rain to completely clear the air though...so we should expect at least SOME smoke in the Edmonton region Friday.
The Air Quality Health Index MIGHT improve slightly on Friday, but then the modelling has another blast of thicker smoke pushing in from the east on Saturday.
Sunday's a bit more uncertain. However, smoke looks like it'll PROBABLY still be lingering in the Edmonton region.
Bottom line: While the AQHI readings may vary a bit, we should expect "high to very high risk" conditions for most, if not all, of the next few days. And, any improvement likely doesn't get us any better than a "moderate to high risk."
As for the shower/thunderstorm risk:
Thunderstorms (possibly severe) are very likely in western Alberta today. Gusty wind and large hail are the main threats.
In the Slave Lake/Whitecourt/Edson/Drayton Valley regions, there's also the threat of some isolated downpours to go along with the wind and hail.
Edmonton and area has a slight risk of seeing a shower or thunderstorm roll through the region late this evening/overnight.
Friday's showers and thunderstorms will also be mainly focused on western (and southern) Alberta. There's a good chance we'll see some occasional scattered showers in the Edmonton area, but it doesn't look like any significant moisture.
Here's the forecast for Edmonton and area:

A man who has brain damage has a murder conviction reversed after a 34-year fight
A man who has brain damage and was sentenced to life in prison for the murder of a shopkeeper in London had his decades-old conviction quashed Wednesday by an appeals court troubled by the possibility police elicited a false confession from a mentally vulnerable man. Oliver Campbell, who suffered cognitive impairment as a baby and struggles with his concentration and memory, was 21 when he was jailed in 1991 after being convicted based partly on admissions his lawyer said were coerced. “The fight for justice is finally over after nearly 34 years," Campbell said. “I can start my life an innocent man.” Campbell, now in his 50s, was convicted of the robbery and murder of Baldev Hoondle, who was shot in the head in his shop in the Hackney area of east London in July 1990. He had a previous appeal rejected in 1994 and was released from prison in 2002 on conditions that could have returned him to prison if he got into trouble. Defense lawyer Michael Birnbaum said police lied to Campbell and “badgered and bullied” him into giving a false confession by admitting he pulled the trigger in an accident. He was interviewed more than a dozen times, including sessions without either a lawyer or other adult present. His learning disability put him “out of his depth” and he was "simply unable to do justice to himself,” Birnbaum said. He said the admissions were nonsense riddled with inconsistencies that contradicted facts in the case. At trial, he testified that he was not involved in the robbery and had been somewhere else though he couldn't remember where. A co-defendant, Eric Samuels, who has since died, pleaded guilty to the robbery and was sentenced to five years in prison. At the time, he told his lawyer Campbell was not the gunman and later told others Campbell wasn’t with him during the robbery. Lawyers continued to advocate for Campbell that he wasn't the killer and his case was referred to the Court of Appeal by the Criminal Cases Review Commission which investigates potential injustices. The three judges on the Court of Appeal rejected most of Birnbaum's grounds for appeal but said they were troubled by the conviction in light of a new understanding of the reliability of admissions from someone with a mental disability. The panel quashed the conviction as 'unsafe,' and refused to order a retrial.
