We're leaving summer on a high note, and starting fall on one, too – for the first half of the day, at least!

Today's "trifecta" weather – that's a high pressure ridge, the ensuing sun, and westerly wind off the Rockies – should pump us well above seasonal. The 40 km/h gust expectations will stand out as the 'great contentious issue' for the day.

So, as I said on Twitter…

I hope you enjoy the last full day of summer 2021! pic.twitter.com/8GQsuxLW1p

Tomorrow, the start of autumn takes mere hours to turn cooler; a frontal passage will drop our temperature and raise our wind speed yet again. We can expect our temperature Thursday to bear the brunt of this cooling, though it, too, is temporary. Warmer weather is just around the bend, as a second high pressure system is nipping at this cool air's heels. That'll make for a lovely first weekend of fall.

Of some interest to the beautiful moon last night, our pals in Edmonton posted this infographic about the Harvest Moon:

When the sun sets tonight, a #FullHarvestMoon will rise. It will appear full for a few days ahead of #Autumn on Wed. The moon with clearer skies will lead to a brighter evening. Nickname given as farmers used to take advantage of the extra light for harvesting. #yeg #yegwx pic.twitter.com/DxWTk2WOHS
