A line of strong to severe thunderstorms is expected to develop in Southwestern Saskatchewan during the early afternoon hours on Sunday. This line will slowly track to the northeast throughout the day and could being damaging wind gusts to much of Central Saskatchewan including Moose Jaw, Regina and Saskatoon. The main risk associated with these storms will be wind gusts up to 100 km/h and quarter-sized hail.
The overall tornado threat is low, however, there are some indications that the environment will be favourable for the development of funnel clouds. These funnel clouds typically don’t pose a threat to those on the ground, but they can touch down and become a landspout tornado in rare cases.
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.
