Severe thunderstorms over southwest Manitoba Sunday evening.. showers/storms bypass Winnipeg/northern RRV yet again..
Some stunning images sent to the Weather Network of locally severe thunderstorms that affected southwest Manitoba last evening. The left image shows a shelf cloud passing over Oak Lake, MB which produced strong wind gusts, heavy downpours, and quarter size hail. The right image is a beautiful shot from Virden of mammatus clouds being underlit by a setting sun. Mammatus cloud sometimes accompany tornadic storms, and this cell did indeed produce a brief tornado just east of Virden Saturday evening. The strongest storms generally moved from the Transcanada highway near the SK border down towards the southern RRV last night, once again bypassing Winnipeg and the northern RRV. About 5-15 mm of rain was recorded in storms last night over the southern Red River valley.
These storms come from the same system that pounded southern Saskatchewan Saturday with some exceptionally heavy rain and hail north and east of Regina. Hail up to a foot deep fell on Highway 6 north of Regina Saturday afternoon (image left) which disrupted travel in the area. 50-70 mm of rain flooded areas just east of Regina along with hail and local funnel clouds.
