Thunderstorms and heavy rain possible Friday night
A trough of low pressure over Saskatchewan will be advancing towards southern Manitoba Friday into Friday night. Southerly winds ahead of the trough will bring a warm and increasingly humid airmass over southern MB during the day, with thunderstorms developing by late afternoon or evening. The storms may generate heavy rainfall over the Red River valley Friday night into Saturday morning with rainfall amounts of 20-30 mm likely, with 50 mm or more possible in some areas. Some storms may be severe with large hail and damaging winds. Cooler and unsettled weather will follow on Saturday before a drying trend Saturday night into Sunday.
