Hot spell forecast for next week.. locally strong thunderstorms possible Saturday into Saturday night
Models are cranking up the heat beginning this weekend, and continuing much of next week. A warm front is forecast to push through southern MB on Saturday, which could trigger some heavier thunderstorms especially by Saturday night. (Note that SPC is indicating a slight risk of severe storms for Saturday over the northern Plains. Models hint at potential for strong elevated thunderstorms Saturday evening/night anywhere from North Dakota into central MB) We start getting into the steambath on Sunday with hot and humid conditions as the warm front pushes north of us, with afternoon highs of 30-33C and humidex values near 40. The hot and humid conditions are expected to persist through Thursday with daily highs in the 30-33C range before a cold front sweeps through late in the week with cooler air by next weekend. Although much of next week should be generally storm free as warm air aloft caps thunderstorm development over southern MB, there is a chance of daily scattered thunderstorm activity as weak impulses ride the upper ridge, especially through the Riding Mtn/Interlake areas. All in all though, looks like a steamy stretch of weather coming up, with potentially 5 straight days of 30C plus weather next week.
