Some “fresh” Saskatchewan smoke is expected to take a stroll through the area on Wednesday night (maybe?) and Thursday.
If you didn’t know, the cause of our sunny skies today is a high in northwestern Alberta. If you understand anything about highs, you would know winds flow out clockwise from them. Currently there are fires in central Saskatchewan. The smoke would go to us because of the high being north of us, but remember the high is actually northwest of us, meaning the smoke should miss us. The end.
But wait. Pressure systems, or rather all weather systems go west to east. It’s called the Earth not being flat. That means when our high moves east, the winds will shift from northeasterly to southeasterly. If the smoke is already to the southeast of us, then the shifting winds will bring them to us!
Of course, the smoke not coming directly from the fires means it will have dispersed a great amount. The smoke that looks like it may be coming for us would have probably already come out of the fires 18-24 hours ago. This means when they reach us, you’ll likely be able to tell it’s in air, but it wont be very thick.
So what about timing? Environment Canada doesn’t like to go far in the future, so it’s either just Thursday or no smoke at all. AQICN says Wednesday night and Thursday. Accuweather says no smoke, and FireSmoke.ca says starting Thursday morning, and actually continuing to Friday morning.
