Wednesday, March 6th 2019, 5:18 pm - Meteorologist Kelly Sonnenburg takes a look at signs of spring on the horizon.
The official start to spring is just around the corner, but winter temperatures have been tenacious across the Prairies for the start of March. Extreme cold warnings have dropped off (for now) across the Prairies, but the extremely cold airmass that's been lingering over the region has already brought new record lows to parts of Alberta. It may be hard to picture when you're bundled up against daytime highs in the minus teens, but there is finally a glimmer of hope on the horizon. More on cracking out of the deep freeze, below.

A persistent circulation stuck over Hudson Bay has been behind a lot of the dogged cold that's kept cities like Edmonton below the freezing mark for more than a month. The last time Edmonton topped 0 degrees was January 31; although that might seem like getting off easy if you're in Thompson, Manitoba, where the thermometer hasn't crept into the positive numbers since November 5.
"It's been so cold that we've already broken our all-time coldest March temperature for both the city of Lethbridge and Sundre, Alberta over this past weekend as temperatures dropped down to about -40°C," says Weather Network meteorologist Kelly Sonnenburg.
A GLIMMER OF SPRING HOPE, MILDER AIR
While this week still features some below-seasonal temperatures for the Prairie provinces, there are some glimpses that spring may start fighting back against winter's chill.
"As we head towards the end of the week and into early next week, temperatures will start to climb back closer to seasonal values," Sonnenburg says.
A relatively mild southwest flow is even expected to mark a stretch of days at or above the freezing mark for some communities by next week.
