Sizzling summer-like heat will cast a wide blanket across the Prairies this week. Temperatures will soar into the 30s, first in western sections before spreading east through the coming days. However, there won't be much rainfall, something that is sorely needed to combat the ever-growing drought, as a potent upper ridge in place will prevent any systems from swinging through. Far-reaching 30-degree daytime highs will be seen by Wednesday, with some areas in Manitoba feeling close to 40 with the humidex on Friday.

THIS WEEK: WIDESPREAD SUMMER-LIKE HEAT, REMAINING DRY UNTIL LATE WEEK
A southerly flow across Western Canada is taking centre stage this week, thanks to a strong upper ridge of high pressure.
Temperatures will soar the upper 20s for much of the southern Prairies Tuesday, possibly reaching or exceeding 30°C in southwestern Alberta. By Wednesday, much of southern Alberta and Saskatchewan will hit or exceed the 30-degree mark.
As well, a surface low sliding east across Manitoba could spark off thunderstorms in the southern areas Tuesday afternoon. Any that do fire up are expected to remain non-severe in nature, but may still bring small hail and heavy rainfall.
The heat will continue spreading further east into more southern areas of Saskatchewan and into Manitoba by late week.
"This is a great start to June. We are going to see those hot temperatures spread east as that ridge gets stronger," said Ida Hung, a meteorologist at The Weather Network.
By Friday, parts of southern Manitoba, including the city of Winnipeg, could see humidex values inch closer to 40. Widespread temperatures into the mid-30s are expected, and a few spots could even reach the upper 30s.
Accompanying the warm-up will be abundant sunshine, continuing through until late week — resulting in a drier pattern once more.
However, there is an increasing threat for thunderstorms for Alberta on Friday. Following that, there will be more widespread rain and thunderstorms for parts of the region on the weekend as a system develops over Alberta and tracks east. This will be accompanied by a considerable temperature drop for the aforementioned province, with daytime highs sinking to the mid-teens.
South of the widespread rain, there is the potential risk for thunderstorms, some could be strong or severe in nature, but overall the southern Prairies will become very dry again. But forecasters are watching the potential for a more stormy pattern for next week.
LITTLE RELIEF FOR DROUGHT CONDITIONS AS MOST OF THE WEEK REMAINS DRY
While there has been some beneficial rain earlier in the month, helping to push some drought stricken areas out of "severe" territory, some areas in southern Manitoba still remain very dry.
Parts of southern Alberta remain in a moderate drought, which will likely worsen this week with no widespread rain in the short-term forecast for most of the southern Prairies.
The upper ridge in place will deter any systems from moving into the region, which could become a growing concern once again, with some regions already in desperate need of some rain.
