Severe Thunderstorm Risk, Including Possible Tornadoes, Forecast for Southern Saskatchewan

Southern Saskatchewan is facing a heightened risk of severe thunderstorms today as a developing low-pressure system moves across the province, creating favourable conditions for dangerous weather.

An organized severe weather event is expected to develop as a low-pressure centre forms near the Saskatchewan border. A cold front extending to the southwest and a warm front stretching across southeastern Saskatchewan are expected to provide the ingredients needed for strong thunderstorm development through the afternoon and evening.

Atmospheric conditions are becoming increasingly unstable, with rising temperatures and moisture levels supporting thunderstorm growth. Weather models indicate instability values have increased compared with earlier forecasts, raising concerns about the potential intensity of storms.

All forms of severe weather are possible, including large hail, damaging wind gusts and isolated tornadoes. The greatest tornado threat is expected across southeastern Saskatchewan, particularly along and south of the Trans-Canada Highway corridor from east of Swift Current to the Manitoba border.

While heavy rainfall is possible, flooding is not expected to be the primary concern due to the relatively fast movement of storms. Instead, large hail and strong winds are expected to pose the greatest hazards for many communities.

The severe weather threat is expected to continue into the evening and overnight hours. Strong thunderstorms may persist as they move eastward, reaching western Manitoba by Friday morning.
