Daytime highs around 30C – challenge record highs across the Southern Prairies this week. Little reprieve in sight from Extreme fire conditions. Locally heavy thunderstorms expected by mid-week.
EXTREME FIRE CONDITIONS & RECORD HIGHS
The last full week of May will feel more like summer across the Canadian Prairies. Rising fire ratings this week, can be attributed to a large ridge in the Jet-stream – sending temperatures soaring up to 10C above seasonal. This has led to the first issuance of a Heat Warning for 2018 – for Central and Northeastern Alberta.
Hot and dry conditions have led to extreme fire conditions across the Canadian Prairies (Alberta, Saskatchewan & Manitoba).
Current Hotspots being detected by satellite show several brush, grass, and vegetation fires in Southern Manitoba – continuing into Saskatchewan.
“A hotspot is a satellite image pixel with high infrared intensity, indicating a heat source. Hotspots from known industrial sources are removed; the remaining hotspots represent vegetation fires, which can be in forest, grass, cropland, or logging debris.” – Natural Resources Canada
Fire conditions continue to worsen this week ahead of a threat for thunderstorms.

If you are a smoker, be mindful of where you throw cigarette butts. Avoid any outdoor burning or use of any source of ignition while outside.
RISK FOR THUNDERSTORMS MID TO LATE WEEK
The threat for thunderstorms develops Wednesday for Southern Saskatchewan. Moving east into Manitoba for Thursday. We are closely watching for a risk of severe thunderstorms for Thursday in Southern Manitoba. Thunderstorm risk retreats further west into Alberta for Friday and Saturday.
With thunderstorms comes the risk of lightning – an ignition source for fires.
Unfortunately, little relief from extreme fire conditions is expected due to the isolated and convective nature of thunderstorms. Conditions are expected to improve some – especially for Southern Saskatchewan – by late week.
We will be closely monitoring the situation.
