Windy Weekend Brings Summer Heat Back to Winnipeg

Brad

After a cool end to the week, breezy southerly winds will strengthen this weekend and bring summer temperatures back to the region.

Today will be one last seasonably cool day across the Red River Valley as an Arctic ridge exits the region. Temperatures will top out at only around 19°C with light winds. Winnipeg should see sunny skies, so although it’s cool, the light winds and sunshine should make for a pleasant June day. Temperatures will dip to a low near 8°C tonight with light southeast winds.

Temperatures will return to seasonal values on Saturday with a high near 23°C under mainly sunny skies. Winds will pick up through the morning into the 30 to 40 km/h range out of the southeast. With seasonal temperatures and a nice breeze keeping the bugs at bay, it will again be a pleasant June day! Temperatures will head to a low near 14°C on Saturday night.

Moderate southeasterly winds will develop over southern Manitoba this weekend.

The city will see partly cloudy skies and no notable humidity will accompany the heat. Winnipeg will see more cloud cover on Sunday night with a chance of showers or thunderstorms. Temperatures will drop to a low near 17°C as the winds continue through the night.

Long Range Outlook

Next week will continue to be seasonably warm with highs in the mid-20s. Some unsettled conditions will develop as a series of low pressure systems move through. As is typical with summer lows here, they will be convectively driven so rainfall patterns will be hit and miss. Early indications are that western Manitoba will see most of the rain next week, providing some relief to flooded regions in the southeastern corner of the province. That said, all areas in southern Manitoba will see a chance of showers or thunderstorms through the first half of the week.

Today’s seasonal daytime high in Winnipeg is 23°C while the seasonal overnight low is 10°C.

Winnipeg will see one more warm and humid day before cooler, drier air sweeps into the region.

Winnipeg will see temperatures, and the humidity, climb to start the work week. Skies will mix out this morning as a warm front pushes northwards through the region. Behind the warm front, temperatures will climb to a high near 28°C; with the humidity that arrives today, that will end up feeling more like the mid-30s. A cold front will begin to push across the Red River Valley this afternoon and be the focus for another round of thunderstorms. While a majority of the activity will likely develop over southeastern Manitoba, there is still a slight chance for a few showers or thunderstorms Winnipeg and areas south. Any thunderstorms that develop today will have the potential of producing severe weather with primary threats of large hail and/or damaging wind gusts.

Drier air will push into the region tonight as winds pick up out of the northwest to around 30 km/h overnight and temperatures drop to a low near 12°C. Skies will see increasing cloud through the night.

Pleasant Days Ahead With Increasingly Unsettled Nights

Brad Leave a comment

Winnipeg will see temperatures begin to climb again as a deep southerly flow begins pushing summer heat back towards the region. With it, though, will come increasingly unsettled overnight conditions.

Today will be a cool but pleasant day in Winnipeg. With partly cloudy skies and breezy northwest winds near 30 gusting 50 km/h, temperatures will climb to a high near 19°C. A ridge of high pressure sliding across the province will ensure the winds drop off quickly in the evening. Temperatures will dip to a low near 8°C.

On Saturday, seasonal temperatures will return to Winnipeg with highs climbing to around 22°C. Southeasterly winds will begin to pick up in the afternoon into the 20 to 30 km/h range. Skies should be mainly sunny as well, making for a great summer Saturday. Conditions will turn heading into the evening, though, as clouds move in ahead of a warm front approaching the region. Overnight, a strong low-level jet will develop, supporting a broad area of showers that will lift northwards through the night. The showers will have limited instability, so while isolated thunderstorms will be possible there won’t be a notable severe weather threat. The showers will exit the region late overnight or early Sunday morning. The southeasterlies will persist right though the night at 30 to 40 km/h and temperatures should dip to a low near 13°C.

Showers will move through southern Manitoba on Saturday night.

Sunday will bring mostly cloudy skies to the region with winds gradually easing to 30 gusting 50 km/h. After Saturday night’s showers move out, the day should stay dry. The high temperature will be a bit tricky and highly dependent on how much sunshine the city ends up with. A rather warm and humid summer air mass will be moving into the region. If skies stay overcast, Winnipeg may see a high of only 23 or 24°C. If the sun manages to poke out a bit more, temperatures could reach as high as the upper 20’s. For now, we expect a few sunny breaks but otherwise mainly cloudy skies and a high near 26°C.
