Showers coming to southern Alberta, but not enough
The action is north of Calgary, but the local effects will be palpable.
The Gulf of Alaska low closing in means we can further fine-tune its effects, but first, let's examine last night:
Oh, what a night!
Severe #abstorm watches came through across the board, with #Calgary falling under a warning, too - but the path of least resistance for that particular storm drove it to the southeast, instead. #yyc pic.twitter.com/ShzvoRiOnK
Environment Canada played it all properly, delivering a warning to the Calgary area for severe storms – especially after that gust front pushed in and amplified our maximum wind gusts into the 70 km/h range briefly.
The storm ended up pushing off to the southeast and weakening – it was following the path of least resistance.
On to the Next Big Thing as weather-makers go. Friday, the stacked low (it exists in the upper and lower atmosphere) presses across the Rockies. Thursday, we're under the lingering effect of our ridge, which makes for our heat warning lasting another day. That falls off tomorrow with the low.
Showers are likely to rip from the local foothills as that low arrives, some of which may trigger thundershowers. Heavier showers will roll into northern Alberta. Unfortunately, we're still lacking for precipitation in southern Alberta.
When showers roll through, they may develop into spotty thundershowers with a largely west-to-east trajectory.
After that, the cooler air starts to fold in. Our temperatures will assuredly fall away from heat warning criteria and stay there for a couple of days.
Unfortunately, the strong shower potential for southern Alberta that was forecast for Sunday has fallen off considerably.
There's still time for that to change, which would be handy – Agroclimate Canada's charting below shows our precipitation percentiles in the Calgary zone between 10th and 20th percentile. Not good.

Our forecast conditions will be elevated by wind today, tonight, and tomorrow.
While that cold front lies beyond us, the continuing effects are palpable. We're still cool, we're still dealing with a touch of wind
A hefty uplift may trigger showers, with a slighter potential for thundershowers associated with this frontal passage.
