I know....it's Friday, and you don't want to think about Monday, but....
Heads up for southern Albertans.....Monday will be snowy. Not a lot, 5-10 cm, but the first significant snow of the year is never fun on the roads. #yyc #abstorm Image from pivotalweather.com.

I'm an author! (sort of). Excited to share that I wrote the weather content for the 2026 Almanac edition of the iconic Canadian magazine Harrowsmith. It was so much fun to work on this, and I'm very thankful for the opportunity. It goes on sale today (July 28).

I really should be doing my taxes. Or fertilizing my lawn. Or seeing a podiatrist.

ONE LAST FLIPPIN’ COLD DAY. In Calgary, we’re 13 degrees below average so far in February. This changes tonight, as temperatures begin to rise. Tomorrow’s bar on this chart will be red (above avg) - the first of many. #yyc

Not a surprise to learn January in #Calgary was warmer than average. The average temperature was -4.0....long term average is -7.6. La Nina has since kicked in, and February has begun cold. The map on the right shows #yyc temps for the next 3 months should be near or below average. #yyc

More snow along the US Gulf Coast (circled) this week than across most of Canada! At least according to this map, which shows expected snow from now until the evening of Sunday Jan 26. Quite remarkable how much of North America can expect snow in the next seven days. #snow #winter #lanina
