It's been a very wet and gloomy stretch over the past 10 days or so, and it doesn't look any better for the next few days either. A stubborn slow moving upper low pressure area over the Dakotas will maintain a cyclonic flow of cloudy cool and unsettled weather over southern Manitoba through the rest of the week into the weekend. Periodic showers will be possible every day, adding to the already soggy rainfall totals of the past two weeks. Some parts of south Winnipeg and southeastern MB have seen over 120 mm of rain in May, twice the average for the month. Luckily, dry conditions earlier in the spring have helped to minimize widespread flooding problems.. however the wet weather is starting to become a concern over southern and eastern sections of the province which have been hardest hit in recent days by heavy rain and lack of sun.
Note that June is normally the wettest month over southern Manitoba as weather systems over the Dakotas tap warm and humid air spreading north from the American midwest, creating showers and thunderstorms over the southern Prairies.
