Several atmospheric factors will come together late today and into early tonight leading to the formation of severe thunderstorms from northeastern Montana to southeastern Alberta, southern Saskatchewan and perhaps extreme southwestern Manitoba.
The main risks will be damaging straight-line winds and large hail. However, atmospheric conditions will also be favorable for the formation of tornadoes early this evening, especially over extreme south-central Saskatchewan.
Hot air to the south of the thunderstorms will surge into extreme southern Manitoba on Thursday with some areas reaching +32 C. (~90 F.)
The air will also get very unstable again later Thursday afternoon and evening with the chance for damaging thunderstorms from southeastern Saskatchewan through the western two-thirds of Manitoba.
