Severe thunderstorms possible over southern MB this afternoon/evening..
Severe thunderstorms are possible this afternoon and evening across southern MB as an upper level disturbance tracks into southwest MB tapping an unstable airmass over the area. Strong to severe thunderstorms are expected to develop across SW Manitoba this afternoon and push eastward into the Red River valley later this afternoon and into SE Manitoba this evening. The strongest thunderstorms will be capable of producing large hail of 2 to 3 cm in diameter, torrential downpours of 25-50 mm/hr, and damaging wind gusts of 90 km/h or more. In addition, conditions are favourable for some storms to produce funnel clouds and/or tornadoes.. similar to what was reported in southern SK Monday afternoon. Stay tuned on this developing situation..
