The environment is favourable for isolated severe storms in South-central Saskatchewan on Tuesday afternoon and evening. However, storm development is questionable which is required to take advantage of the environment. If we do see storms develop somewhere around Assiniboia and Moose Jaw, they could reach severe levels with quarter-sized hail, 90km/h wind gusts and maybe even a landspout.

Landspout: A landspout is a type of tornado that forms under a weak thunderstorm. Unlike traditional tornadoes, which develop from supercell thunderstorms and are associated with a rotating updraft called a mesocyclone, landspouts form from non-supercell storms and do not have a mesocyclone. These tornadoes are generally weaker and shorter-lived than their supercell counterparts but can still pose a threat to property and life, with wind speeds occasionally reaching up to 160 km/h.
