Winnipeg will see another burst of snow later today as warmer air begins spreading into Manitoba.
Forecasts have shifted over the past few days regarding the next low pressure system moving through the province today. What earlier in the week was forecast to weaken as it moves into Manitoba is now expected to maintain its integrity. As a result, not only will skies cloud over today, light snow will spread from western Manitoba into the Red River Valley later this afternoon. Winds will pick up out of the southeast to around 20 km/h as temperatures climb to a high near +1 °C.
The snow will continue overnight before tapering off on Saturday morning. While areas in western Manitoba will see close to 10 cm of snow, amounts in the Red River Valley will be less. Winnipeg will likely see 2 to 5 cm of snow by the time it tapers off, though there is an off-chance of seeing totals in the 5 to 10 cm range. Temperatures will head down to a low near -4 °C tonight.
Skies will stay mainly cloudy on Saturday as a trough of low pressure hanging back into the region continues to weaken. Light westerly winds will develop as temperatures bounce back above freezing into the low single digits for the daytime high. Skies will begin to clear out overnight with a low in the -10 to -5 °C range.
A ridge of high pressure will begin moving into the region on Sunday, bringing partly cloudy skies and light winds. Daytime highs will again climb above freezing into the low single digits. Temperatures will dip down into the -15 to -10 °C range on Sunday night with partly cloudy skies.
Long Range Outlook
The warm-up starts in earnest early next week as an upper ridge begins building into the Prairies. This will push milder Pacific air eastwards, sending daytime highs into the 5 to 10 °C range for much of next week.
It looks dry through much of the week, though a couple passing systems could bring a chance of rain showers or light snow.
Today’s seasonal daytime high in Winnipeg is +4 °C while the seasonal overnight low is -7 °C.
