Conditions are favourable for the development of dangerous thunderstorms that may be capable of producing damaging wind gusts, damaging hail and torrential rain. Very large hail can damage property, break windows, dent vehicles and cause serious injury. Very strong wind gusts can damage buildings, down trees and blow large vehicles off the road. Intense lightning is likely with any thunderstorm that develops. Remember, severe thunderstorms can produce tornadoes. Heavy downpours can cause flash floods and water pooling on roads.
Timing: Late Saturday afternoon and evening, possibly overnight in the extreme southeast.
Threats: 3 to 5 cm hail, wind gusts 90 to 120 km/h and local rainfall amounts of 50 to 75 mm. Possible tornado in southwestern portion of the province from the Red River Valley to the Saskatchewan border.
A trough of low pressure will intersect with a hot and humid airmass over southern Manitoba allowing for the development of severe thunderstorms late this afternoon and into the night. Some thunderstorms will become very intense capable of producing 4 cm hail, heavy downpours, and even tornadoes across southern sections.
