Heat warnings will drop soon; storms possible this weekend in Calgary

AFTERNOON UPDATE: Tonight has a small chance to yield showers, still, to add to the haze and cloud we've been offered. Wind speeds are quite strong already this afternoon, with gusts steady around 40 km/h this week.

Moving into the weekend, storm risks remain, and with them, our chance for severe storms has fallen. It's not gone - but it's dropped substantially in the wake of our ongoing convective inhibition. Otherwise, the storm risk is starting to populate a bit higher Sunday.

MORNING EDITION: It took a few days to get there, but we're starting to see the visualized editions of the thunderstorm potential in our forecast for Saturday evening.

The chance is slimmer even now than it was yesterday; a crisper model image displays instead that activity could deviate wide around Calgary. The current renderings are all over the map; some models are calling for a 3 p.m. storm tomorrow, and others think it won’t roll by until 2 a.m. Sunday. I look at our best chance for storms as part of the daytime heating cycle; therefore, storm activity around the dinner hour becomes most likely.

I have been remiss to mention today's conditions – they simply don't amount to much in our case. Hot, dry conditions are the dominant feature of our forecast. The heat warning continues.

Skipping ahead to Sunday, another shot at showers or thundershowers will sit staunchly atop Saturday's motion; in fact, Sunday holds dependencies on what Saturday does. If we don't get much Saturday, we’re less likely to deal with it Sunday. Convective inhibition may play that role.

After a lengthy stay beneath the ridge, we're on our way out thereafter. It’ll still take until the midweek, but seasonally-normal conditions are coming, and they're bringing showers along for the ride.

CBC says it is cutting 600 jobs, some programming as it slashes budget

The Canadian Broadcasting Corp. and Radio-Canada will eliminate about 600 jobs and not fill an additional 200 vacancies. The cuts at CBC come days after the Liberal government suggested it may cap the amount of money CBC and Radio-Canada could get under a $100 million deal Ottawa recently signed with Google.
