Sweltering summer heat will slowly build into Winnipeg this week as an upper ridge builds moves into the region.
The only significant weather feature for southern Manitoba over the next few days will be a potent upper-level ridge building into the region. As it approaches, daytime highs will slowly climb to around 30°C with overnight lows moving from the mid-teens to around 20°C.
Conditions will remain dry over the next few days with sunny to partly cloudy skies in place right through Wednesday. Overnight Wednesday into Thursday morning there may end up being a chance of showers or thunderstorms as a low pressure system begins moving eastwards across southern Saskatchewan.
Humidity levels should remain comfortable through the first half of the week.
Long Range Outlook
The heat continues into the second half of the week, but Thursday in particularly looks sweltering. As the low pressure system passes by to the north, dew points are expected to climb to around 20°C. Assuming that the region ends up seeing enough sunshine, this would produce humidex values in the upper 30s. The humidity will ease heading into the weekend, but temperatures should remain warm with highs in the upper 20s or low 30s.
Today’s seasonal daytime high in Winnipeg is °C while the seasonal overnight low is °C.
Winnipeg will get to enjoy sunny to partly cloudy skies right through the weekend.
Winnipeg will find itself between two main weather features today: a trough of low pressure laying across the Interlake, and a mid-level disturbance zipping along near the U.S. border. Not being directly affected by either system, the city will see plenty of sunshine today. With a few clouds grazing by, temperatures will climb to a high near 26°C. Winds will be breezy out of the west-southwest at up to 30 gusting 50 km/h. Skies will clear out tonight with winds easing as temperatures head to a low near 15°C.
Saturday will bring partly cloudy skies to the city again as a cold front slumps southwards. Winds will shift out to the north-northwest in the morning, picking up into the 20 to 30 km/h range. There might be a slight chance of a shower midday as the front passes, but it looks like things should stay dry. Temperatures will reach a high near 23 or 24°C behind the front. Winds will taper off in the evening as temperatures head to a low near 12°C.
On Sunday, a ridge of high pressure will slowly build into southern Manitoba. As a result, the city will see mainly sunny conditions with northwest winds around 20 km/h. Temperatures will climb to a high near 23°C, then dip to a low near 13°C on Sunday night.
Long Range Outlook
Next week will see temperatures climbing back into the upper 20s or low 30s as an upper ridge redevelops over the Prairies. Winnipeg should see plenty of sunshine through the first half of the week, then unsettled weather may return for the second half into the weekend.
Today’s seasonal daytime high in Winnipeg is 26°C while the seasonal overnight low is 13°C.
The dry conditions of just a couple weeks ago are almost a distant memory with more showers and thunderstorms possible through the second half of the week.
More showers are on the way for Winnipeg later today. The city will see cloudy skies as a low pressure system works its way across the province. By midday, scattered to widespread showers will develop ahead a trough of low pressure with the chance of embedded thunderstorms. The unsettled conditions should clear out by late in the afternoon with the skies clearing out a bit after that.
Temperatures will be cooler today; Winnipeg will have southerly winds to around 20 km/h and a high near 23°C. It will continue to be a bit muggy today with dew point temperatures near 18°C with only slight relief tonight. The city will see a low near 16°C with partly cloudy skies.
Thursday will be a bit of a tricky weather day over the region. Warmer weather will return to Winnipeg with temperatures climbing to around 28°C with muggy dew points near 18 or 19°C. Winds will pick up out of the southwest into the 20 to 30 km/h range.
The southwesterly flow over southern Manitoba will push a broad frontal wave into the province. As it moves into place, a low pressure system will push into western Manitoba from Saskatchewan. The interaction of these two systems will produce a conditional threat of thunderstorms over the region late in the day. There will be a chance that these thunderstorms, should they form, could be severe. Unfortunately, the subtle nature of the interactions that will lead to thunderstorm development can’t be forecast with too much accuracy this far out. Be sure to check out ECCC’s thunderstorm outlook on our Bulletin Viewer on Thursday morning for a complete discussion on the day’s thunderstorm potential.
Warmer weather will return to southern Manitoba on Thursday.
Once the thunderstorm threat diminishes on Thursday evening, the city will see partly cloudy skies with temperatures heading to a low near 15°C. Winds will persist out of the southwest near 20 km/h through the night.
Partly cloudy skies will be in place for Winnipeg on Friday, although cloudier conditions won’t be too far to the north. Temperatures will reach a high near 24°C with westerly winds of 30 gusting 50 km/h. Of note will be that those westerly winds will finally flush the humidity out of the region, bringing a return of more comfortable conditions.
Winnipeg will see a few clouds on Friday night as winds ease and temperatures drop to a low near 13°C.
Long Range Outlook
Winnipeg will see variable cloudiness this weekend with a chance of a few showers on Sunday. Settled conditions will move in after that with plenty of sunshine through next week. Temperatures will be near-seasonal through the weekend, but a warm-up is forecast by mid-week with daytime highs returning to the 30°C mark. Humidity levels are forecast to stay low through much of next week.
Today’s seasonal daytime high in Winnipeg is 26°C while the seasonal overnight low is 13°C.
Winnipeg may see a few showers or thunderstorms today and Wednesday, but the summer heat and relatively humid conditions continue.
The warm and humid weather continues this morning, but relief is on the way. Winnipeg may see a thunderstorm to start the day, but it’s dependent on where the overnight activity decides to move. Most guidance suggests the line will remain north of the city, but there’s a small chance that some new thunderstorms will develop along the southern end of the line. After that passes this morning, the region will see a mainly sunny morning with mixed skies in the afternoon. Temperatures will climb back up to 29 or 30°C with humid conditions continuing. A weak cold front will sweep through late in the day, bringing another chance of showers or thunderstorms to the city.
Winds will gradually turn northwesterly and strengthen to around 30 km/h through the day today, then ease in the evening. Winnipeg will see partly cloudy skies tonight as temperatures drop to around 17°C.
Tuesday will bring increasing cloudiness in the afternoon as the next low pressure system approaches. While still noticeable, the humidity will be a bit lower and comfortable as climb to a high near 26°C. Skies will remain mostly cloudy on Tuesday night with a small chance of showers. Temperatures will dip to a low near 17°C again.
While still humid, Tuesday will bring some relief from the humidity in place over the region on Sunday and Monday.
Unsettled weather returns on Wednesday as a low pressure system crosses the province. The showers or thunderstorms are likely, particularly heading into the afternoon. Early indications are that much of the Red River Valley will see 5 to 15 mm, but the convective nature of the rain will mean some places see more, and some less, than that. All the cloud cover will mean cooler temperatures with a high near 23°C in Winnipeg. The rain should taper off by evening leaving partly cloudy skies overnight.
Long Range Outlook
Thursday will likely bring mixed skies and another small chance of thunderstorms, then a big pattern change moves in. While temperatures won’t cool down too much, a much drier air mass is forecast to move into the region. The weekend should bring highs in the mid- to upper 20s and plenty of sunshine!
Today’s seasonal daytime high in Winnipeg is 26°C while the seasonal overnight low is 13°C.
