Southern Manitoba Soaking Marks Arrival of Cooler Weather

A Colorado Low will bring widespread rain to southern Manitoba today and usher in cooler temperatures for the rest of the week.

Winnipeg will see cloudy skies today with rain beginning midday as it spread northwards out of North Dakota. Rain will move into all of southern Manitoba today and gradually lift northwards through the night. The organized rain should taper off by Thursday morning across much of southern Manitoba.

Rainfall totals in Winnipeg will likely sit in the 20–30 mm range with slightly higher amounts to the west along the Red River Valley escarpment. Much of southwestern Manitoba will likely get a good soaking with 25–40 mm possible throughout that region. Rain will also fall to the east of the Red River Valley, but accumulations should be a bit less in the 15–25 mm range.

Temperatures will stay steady around 9 °C with westerly winds up to 30 km/h. Precipitation will taper off Thursday evening, then winds will ease and temperatures will dip to a low near +3 °C.

Friday will bring westerly winds of 20–30 km/h to Winnipeg with temperatures climbing to a high near 9 °C again.

Temperatures will be cool on Friday night with a low near 1 °C and light winds under clearing skies.

Long Range Outlook

Temperatures will warm a bit this weekend as a push of mild Pacific spills eastwards across the Prairies. This will set up another low to start off next week that may bring another batch of showers to the region.

Today’s seasonal daytime high in Winnipeg is 11 °C while the seasonal overnight low is 0 °C.
