September in Calgary leads with heat, but cooling is on the horizon

Viewer James' photo of Mare's Tails near Brooks.

AFTERNOON UPDATE: Very little to say - it remains hot. Model verification shows a return to normal by Thursday, September 8; that's also the most likely evening where we shut down the record posted through a tweet below, related to consecutive days above 5 C.

Enjoy the heat while it lasts - it's gone soon, to the extent where from Saturday to Wednesday, there are no temperature recurrences in our long-term forecast; that is to say, once we drop off from 25 C, we won't come back for a while.

MORNING EDITION: For many, the feeling about the heat in this forecast aligns something like my captured facial expression here:

This past month had 25 days above seasonal, four below, and two that matched their seasonal values, equating to us ending four degrees above seasonal.

While September holds out for a little while, it’s not a permanent state, by any means. Some looks out to our ten-day forecast show the trend below (I’m almost done with tweets today, I promise) breaking in a big way.

If you're through with the heat, this high-pressure ridge has a close-out date in mind, and it’s looking like we won’t get ten days into the month without low temperatures in the low single digits. For now, though, sun prevails, and the only wrinkle in an otherwise cloudless forecast is today. The cold frontal passage is aiming to generate gusts in the 40s today… and that’s about the most exciting thing taking place.

As for the image (and its question!) at the top of the article… let’s just hold off on that for a little bit. Now that meteorological autumn has begun, the digging begins.

James from Brooks sent this lovely photo of mare's tails by – cirrus clouds that get wispy from upper wind.

An honourable (if controversial) mention goes to Jamie, here, too:
