THURSDAY PM UPDATE: The latest data continues to show the isolated storm risk with no change to the forecast needed.

Thunderstorms are possible in Southeastern Saskatchewan and along the international border during the afternoon and evening on Friday. Some of these storms particularly along the Manitoba border including Estevan, Oxbow, Moosomin and Kamsack could reach severe levels with 90 km/h hour wind gusts and nickel-sized hail. Funnel clouds and maybe even a landspout isn’t out of the question.

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.
