Extended Heat Warning for Winnipeg
A heat warning remains in effect for Winnipeg as humidex values are expected to reach 40°C for one last time on Friday. Daytime highs will be at or above 32°C, with overnight lows remaining above 16°C. The intense heat is due to an upper-level ridge persisting over the area, bringing extreme daytime temperatures and high humidex levels, with little relief overnight. A reprieve from the heat is anticipated starting late Friday and through the weekend as the warmest air moves southward.
