Increasing winds and heat for Sunday..
Perfect weather today will give way to more uncomfortable conditions Sunday as a strong southerly flow of hot and more humid air spreads into southern Manitoba. A developing low pressure system over Montana will push a warm front across southern MB overnight into Sunday morning with a few thunderstorms likely along the front, especially north and west of Winnipeg. As the warm front pushes north, gusty southerly winds of 40 to 60 km/h will develop over southern MB Sunday tapping a very warm airmass over the Northern US plains. Temperatures of 32-35C are likely across southern MB and the RRV by Sunday afternoon, with humidex values of 40-43C. The hot and windy conditions will continue through Sunday evening with temperatures likely remaining near 30C through midnight. A sharp cold front will cross southern MB Monday bringing showers and thunderstorms along with cooler temperatures.
