More rain will move through the Winnipeg area today, but a high pressure system will bring sunshine for the weekend.

A low pressure system crossing the province today will bring unsettled conditions to the Winnipeg area. Rain moved into the region overnight and will continue as widespread rain and showers through the day today. Northeast winds up into the 40 to 50 km/h range will keep temperatures cooler with a high in the upper teens this afternoon.

The rain will begin to break up this evening as this system’s upper-level disturbance curls to the south into North Dakota. Temperatures will head down to a low near 10 °C with easing winds.

Storm-total rainfalls will likely reach 25 to 50 mm in many areas in southern Manitoba, including Winnipeg.

For the weekend, a broad area of high pressure will build across the Prairies. This will bring sunnier skies but cooler temperatures will linger across the region. High temperatures in Winnipeg will reach the upper teens or 20 °C on Saturday, then climb into the low 20s on Sunday. Winds will be northerly at around 20 km/h on Saturday and southerly with similar speeds on Sunday.

Long Range Outlook

Another low pressure system is forecast to eject across the Prairies later Sunday and could bring showers and thunderstorms to southern Manitoba on Sunday night. The wet weather could last into Monday as an area of broad rainfall or several waves of thunderstorms…it’s not clear yet which way the system will develop.

Unsettled conditions with possible showers will linger behind this system through Tuesday. After that, it looks like conditions will settle somewhat, but a low chance of pop-up showers will likely last through the week.

Today’s seasonal daytime high in Winnipeg is 25 °C while the seasonal overnight low is 12 °C.
