Thunderstorms have already rumbled through the Winnipeg area early this morning, and storms are still brewing to our west and southwest as we speak. Severe tstorm warnings are in place due to excessive rainfall. Some areas have already seen over 40 or 50 mm of rain this morning west of Winnipeg.
Thunderstorms are likely throughout south-central and southeastern Manitoba this afternoon and evening. The main threats are large hail, damaging winds and excessive rainfall. The storms are slow movers today, which explains why some areas are getting such high rainfall amounts. Also, they are quite isolated as a result. For example, Oak Bluff had about 30 mm of rain this morning, while some parts of Winnipeg barely had a drop.
These showers and storms are expected to continue tonight, mainly over southeastern Manitoba, before moving out into northwestern Ontario by afternoon tomorrow. Hot and sunny weather will return behind the morning rain for the afternoon. Highs in the low thirties and humidex values in the high thirties and approaching 40 are expected for Friday. Saturday will be similarly hot, albeit less humid.
