It is shaping up to be a stormy day in southern Manitoba. Rain and thunderstorms crossing North Dakota have spread north of the border and are moving east across southern Manitoba this afternoon. Environment and Climate Change Canada said the risk of severe convection will likely be in North Dakota, but it can’t be ruled out in Manitoba either this afternoon or tonight. The weather agency said damaging hail and wind gusts will be the primary hazards, adding a low-grade tornado risk could develop in the southwest. Humidity is helping to fuel thunderstorms, with humidex values expected to reach the upper 20s and low 30s across the south Thursday. Air temperatures will reach the low 20s in the southwest and mid-20s in the southeast. The chance of thunderstorms in Winnipeg and the southeast will grow throughout Thursday afternoon into this evening. Meanwhile, high pressure over northern Manitoba will bring sunshine or a mix of sun and cloud across the region Thursday. Unseasonably warm daytime highs will reach the low 20s. Conditions are similar across northwestern Ontario Thursday, but with warmer highs in the mid-20s. Thunderstorms are expected to miss Kenora and Dryden, but could track through Sioux Lookout and Fort Frances tonight.
