A prolonged period of intense heat is expected to develop across much of the southern Prairies and continue well into next week, prompting heat warnings and special weather statements across parts of Saskatchewan and Manitoba.
Warmer air moving northward will bring daytime temperatures into the low to mid-30s across many southern regions, particularly near the Canada–United States border.
Combined with rising humidity, humidex values are forecast to exceed 45 in some areas, with the most oppressive conditions expected on Sunday.
In southern Saskatchewan, temperatures were expected to reach or exceed 32 C, leading to the issuance of heat warnings for most of the region. Orange-level heat warnings were issued for areas extending from Moose Jaw eastward to the Manitoba border, while yellow-level warnings remained in effect elsewhere.
Meanwhile, a Special Weather Statement remained in effect across Manitoba as hot and humid conditions continued to build. Forecast highs in the Red River Valley on Friday were expected to range between 28 C and 30 C, with humidex values in the low to mid-30s.
The heat event is expected to persist through much of next week, increasing the risk of heat-related illnesses. Residents are encouraged to stay hydrated, limit strenuous outdoor activities during the hottest parts of the day, and check on vulnerable individuals, including seniors, young children, and those with underlying health conditions.
The hottest conditions are expected across southern portions of the Prairie provinces, with little relief anticipated until later next week.
