Cool Weekend, Warming Next Week

Cool weather will persist across Southern Manitoba this weekend as the region remains under the influence of an unseasonably cold outbreak of Arctic air. Temperatures will continue to slowly moderate, however things will be generally mixed through the weekend with a fair amount of cloud and slight chance of precipitation. The real warm-up will build into the region next week, returning us to summer-like weather.

Friday

Mainly sunny

Saturday
14°C / 5°C
Mainly cloudy

Sunday
14°C / 5°C
Mixed skies

Today will be the nicest day that the area has seen in a while thanks to a westerly wind which will help dry out the low-levels and clear out the cloud that has been so persistent over the past week. Thanks to that, mainly sunny skies will be seen in Winnipeg and throughout much of the Red River Valley with westerly to southwesterly winds up to around 20km/h. Temperatures will remain cool, however, as the wind will be outflow from the colder air mass slumping to our south; highs through the Red River Valley will sit near the 13°C mark.

Tonight will see mainly clear skies with a little bit of cloud working in from the northwest late in the overnight period and a low near 4°C.

Cool, Mixed Weekend

Saturday will be a mainly cloudy day as a weak trough of low pressure swings through the Red River Valley. While no precipitation looks likely, there will be a slight chance of some isolated, light shower activity. The temperature will climb to around 14°C for a high temperature in the valley.

Skies will begin to clear overnight as the trough slides off into Ontario and winds back to northwesterly, although another slightly cool shot of air will be moving in behind the trough so some cloud with a chance of showers or drizzle in the lee of the lakes is likely. Lows will be near 4 or 5°C in Winnipeg & through the Red River Valley.

Sunday will bring mixed skies with a chance of drizzle or showers in the lee of the lakes. The high will once again be near 14 or 15°C while the overnight low drops to a repeat 5°C.

Warmer Weather Next Week

The NAEFS is forecasting above-normal temperatures across Southern Manitoba in the 8-14 day outlook.

Manitobans will be repaid for their patience with the cold weather – if medium-to-long-range enesemble models are to be believed – with a hurried return to summer-like conditions. Both Canadian and American models show an upper-level ridge building eastwards across the Prairies next week brining significantly warmer air with it.

850mb temperatures will climb early next week from the –2°C or so they sit at this morning over Winnipeg to around 10°C. This warming aloft will translate to significantly warmer temperatures down here where we live, with daytime highs moving from low-to-mid teens up to the low 20’s.

The weather also looks fairly dry through the warm-up, although by week’s end there looks to be a chance of showers or thunderstorms as a low pressure complex tracks eastwards through the Prairies & Northern Plains of the United States.
