Relief from Prairie heat short-lived as new wave builds
Sunday, August 12, 2018, 9:14 PM - After all-time heat records were shattered Saskatchewan and Manitoba Saturday, with the heat lasting into Saturday, heat warnings were slowly dropping as the weekend comes to a close.
But as the heat shifts eastward out of the Prairies, the relief will be short-lived as a new wave builds. Details below.

- Extreme heat shifts eastward, heat warnings span Manitoba and northwestern Ontario late Sunday, likely to soon drop
- Extreme fire danger remains across southern Prairies
- Relief from the heat will be short-lived as a new wave builds
WATCH BELOW: HEAT BUILDS EASTWARD THROUGH THE WEEKEND
SCORCHING TEMPERATURES LINGER
Heat warnings were slowly dropping late Sunday across the eastern Prairies, though lingering longest in Manitoba.
"The passage of a cold front from northern Manitoba will bring more seasonable temperatures to southern Manitoba for Monday," Environment Canada says.
But this relief will be short-lived, as a new ridge begins to build for the new week.
"The heat will move into B.C. to start the week and move into the western Prairies by Tuesday and eastern Prairies by Wednesday," Weather Network meteorologist Kevin MacKay says. "Temps won’t be pushing 40° this week but most areas across the southern and B.C. Interior will spend a few days above 30°C."
EXTREME FIRE DANGER LINGERS IN THE SOUTH
As goes the heat, so goes the fire danger across the parched southern Prairies. With little in the way of widespread precipitation this summer, many places across the southern Prairies are running at significant rainfall deficits. Swift Current has reported only about 35 mm of rain total for June and July 2018 -- slightly more than 100 mm less than the average June and July rainfall.
Extreme fire danger has been relatively high across much of Western Canada through mid-August, and will remain at extreme levels to start the week in southern Alberta and Saskatchewan..
RAIN AND COOLER WEATHER AHEAD
The upper level trough moved in from B.C. Sunday, bringing a fair bit of rain to parts of the parched Prairies while chasing the heat out of the region, though raising the risk of thunderstorms in some area.
The extent of showers in the south is likely to be limited, with more in the way of isolated thunderstorms and less in the way of soaking rains.
