Continuing Cool With Some Light Snow

Seasonably cool temperatures will continue in Winnipeg through the week with some light snow likely on Tuesday.

A persistent vortex over Hudson Bay continues to push Arctic air southwards across the Prairies. With little forecasted change in the long-wave pattern, below-normal temperatures will be the norm right into next week. Winnipeg will see highs climb just above freezing over the coming few days with overnight lows varying between around -3 or -4 °C and near -10 °C.

Today will bring partly cloudy skies to Winnipeg with a small chance of light snow from passing lake-effect clouds. Skies should clear out tonight as a ridge moves through, allowing temperatures to drop to a low close to -10 °C.

On Tuesday, a disturbance moving into the region will spread cloud into Winnipeg through the day. Light snow will spread through the province, reaching Winnipeg sometime mid- to late-afternoon. The city should see light snow through the night with a few centimetres accumulation possible.

Long Range Outlook
