Mostly Cloudy Skies and Seasonal Temperatures Ahead for Canada Day Weekend

Winnipeg will see seasonal temperatures this weekend with generally cloudy conditions. Unfortunately, it looks like more rain may be on the way for Canada Day evening.

Any last showers or thunderstorms will push east of Winnipeg this morning, but plenty of cloud will remain as a trough lingers through the region. Winds will pick up out of the northeast to 20 to 30 km/h this morning while temperatures climb to a high near 23°C. Winnipeg will have mostly cloudy skies tonight as temperatures dip to a low near 15°C. The wind will ease tonight as it shifts northerly.

Cloudy skies continue Saturday with just a slight chance of showers. Winnipeg should see a high near 24°C with the sun peeking from the clouds a bit late in the afternoon. Winds will be out of the northwest at 15 to 20 km/h. Skies will cloud over again on Sunday night with a low near 14°C.

Unfortunately, more rain may be on the way in the evening on Canada Day

On Canada Day looks to bring a mixed bag to the city. After what looks to be a cloudy start, Winnipeg should see clearing skies for the afternoon with plenty of sunshine as temperatures climb to a high near 25°C. Winds shouldn’t be much of an issue either, increasing out of the southwest to around 15 to 25 km/h in the afternoon. Unfortunately, current guidance suggests that a low pressure system moving into the region will cloud things over again late in the day and bring showers and/or thunderstorms back to the region, possibly making outdoor celebrations a little unpleasant in the evening. The showers are forecast to exit the region overnight as temperatures dip to a low near 14°C.

Long Range Outlook

Next week is starting to look like it will be quite an unsettled one. Forecasts show an increasingly hot and humid air mass pushing northwards into the region. A couple organized systems are forecast to bring showers and the risk of thunderstorms to the region during the first half of the week.

Winnipeg’s seasonal daytime high is currently 25°C while the seasonal overnight low is 13°C.

 

Unsettled Conditions to End The Week

A disturbance crossing the Prairies will bring generally unsettled conditions with scattered showers and thunderstorms to southern Manitoba to round out the week.

Mixed to mostly cloudy skies will move into Winnipeg and the Red River Valley today ahead of an upper-level disturbance slowly moving eastwards through Saskatchewan. Over the next two days, unsettled conditions will produce scattered showers and thundershowers across the region. Slack winds over the region mean that the [thunder]showers will be fairly slow-moving, with local rainfall amounts of 5 to 15 mm possible. Conditions will settle for Sunday, with more sunshine building into the region under partly cloudy skies.

Forecast 24 hour accumulated precipitation shows shows the widespread likelihood for showers across much of southern Manitoba today.

Temperatures will continue to be warm with highs in the upper twenties or low thirties. Lows in the 16 to 18°C range are forecast for the next few days.

Long Range Outlook

Next week will kick off with unsettled conditions as a southerly flow redevelops and taps into warmer, more humid air. Highs will climb back towards 30°C with muggier conditions moving into the region.

Winnipeg’s seasonal daytime high is currently 24°C while the seasonal overnight low is 12°C.

Weather Becoming Hot & Humid with Thunderstorms…Maybe?

A potent low pressure system developing in Alberta today will bring southerly winds to the Red River Valley that will bring heat and humidity back into the region.

Today will be a beautiful day in Winnipeg. Morning sun will give way to some afternoon cloud as temperatures head towards a high near 26°C. Humidity will be low today, and winds will continue out of the southwest at around 20 km/h. Skies should clear out in the evening, then a relatively mild night is forecast with a low in Winnipeg near 16°C. After midnight there will be a slight chance of a shower or thunderstorm as a warm front lifts through North Dakota.

Thursday will bring mixed skies to Winnipeg with southeasterly winds increasing to 30 to 40 km/h. Temperatures will climb to a high near 28°C with humidity gradually increasing through the day. Attention then turns to southeastern Saskatchewan and southwestern Manitoba. By mid- to late Thursday afternoon, the potential for a severe thunderstorm outbreak exists. All of the ingredients are there for potent storms, however whether or not the storms develop as forecast will depend significantly on the region seeing enough sunshine and heating through the day.

Thunderstorms, potentially severe, will likely be moving into western Manitoba on Thursday evening.

If all goes as currently forecast, then thunderstorms would develop and move onto western and southwestern Manitoba in the evening. Depending on how the thunderstorms evolve, the risk for severe thunderstorms with large hail and damaging winds may develop in the Red River Valley overnight. There is the chance that it misses the region, though. Some models suggest the best dynamics lift north of the region and the greatest energy collapses south. For now, know that there’s a chance of thunderstorms Thursday night, with a slight risk they’ll be severe.

Otherwise, Thursday night will a warm one with southerly winds of 15-25 km/h and a low near 19°C.

Friday will bring clearing skies to Winnipeg as a cold front sweeps through the region. It will still be warm with a high near 28°C, but the humidity should drop off markedly with the passage of the front. Winds will shift out of the west midday at around 20 to 30 km/h Winnipeg should see a few clouds on Friday night with a low near 14°C and calm winds.

Long Range Outlook

The weekend will likely bring a fair amount of cloud cover to Winnipeg as a significant storm system moves through the northern United States. At this point it looks like most of the precipitation will remain south of the border, but the Red River Valley may see some rain on Sunday afternoon into the evening. Temperatures will return to seasonal with highs of 23 or 24°C forecast for both Saturday and Sunday.

Winnipeg’s seasonal daytime high is currently 23°C while the seasonal overnight low is 11°C.

Cold Front Brings Monday Showers, Then Settling

A cold front sweeping across southern Manitoba will bring showers to the Red River Valley today, followed by seasonal temperatures and more settled conditions.

Today will be a wet day over the Red River Valley. An upper level disturbance moving northwards along a cold front swinging across the province will support an area of rain that will spread into the Red River Valley this morning. The showers will remain in the region for much of the day, finally clearing out in the late afternoon or early evening.

Many regions in the Red River Valley could see 10 to 20mm of rain by the end of the day today as showers move through the region

Temperatures will reach a high near 21°C early in the day, then cool to around 14°C through the afternoon. Southerly winds near 30 km/h will shift to westerly 30 gusting 50 km/h as the cold front swings through midday, then ease to light by the end of the afternoon. Winds will be light overnight as a ridge of high pressure moves through the region. Winnipeg should see a low near 9°C.

Tuesday will be a slightly warmer day in Winnipeg with temperatures reaching a high near 23°C under partly cloudy skies. The ridge of high pressure will slump to the southeast, replaced by breezy west-southwesterly winds near 30 gusting 50 km/h. It should remain dry over the region, however there is just the slightest chance of an isolated pop-up shower or thundershower late in the afternoon. Winnipeg will see a few clouds on Tuesday night as temperatures dip to a low near 11°C.

Wednesday will bring mixed skies to the region with southwesterly winds near 20 km/h. Winnipeg should see a high near 25°C and that’s about all there is to say! Expect a low near 14°C on Wednesday night.

Long Range Outlook

The warmer conditions will continue through the remainder of the week, however it looks like Friday may bring another batch of showers/thunderstorms through the region. The weekend will bring variable cloudiness with low chances for any precipitation.

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