Pleasant Weekend With a Return to Seasonal Temperatures

Brad

There will be plenty of sunshine in Winnipeg over the coming days as temperatures gradually ease back to seasonal values.

RDPS 2m Temperature Forecast valid 21Z July 1, 2022
Canada Day will bring seasonably cool temperatures and a northwesterly wind to Winnipeg this year.

A low pressure system over Hudson Bay will keep a persistent west-northwest flow over the province for the next couple days. This pattern has brought a slow-moving high pressure system to the Prairies; it will keep the clouds (mostly) away and temperatures seasonably cool.

Temperatures in the city today will climb to a high in the low 20s this afternoon. A northwest wind will pick up into the 20–30 km/h range later this morning. In the afternoon a few clouds will pop up, but it should stay dry through the afternoon. The clouds will dissipate this evening as the wind dies off. Temperatures will head to a low near 10 °C.

A few clouds will move through the region on Saturday as temperatures climb to a high in the low 20s again. Winds will be light as the area of high pressure moves across the province. A weak low crossing Saskatchewan will begin pushing a warm front towards the region by evening. This will bring some cloud cover into the region overnight as temperatures drop to the low teens.

Sunday will be an unsettled day across the region as enough warmth and moisture returns to produce broad instability. A combination of the passing low and stalled frontal boundary will provide support for showers and/or thunderstorms, likely possible at several points throughout the day. Temperatures should reach the mid-20s in the afternoon the afternoon. At this point, severe weather is unlikely, but a few strong thunderstorms may develop.

Conditions should settle on Sunday night with temperatures heading into the low teens.

Long Range Outlook

Forecasts show temperatures staying at seasonal to above-seasonal values through the week with gradually increasing humidity. By the end of the week, daytime highs could reach close to 30 °C. Conditions will be pleasant for the first couple days, but an unsettled pattern could develop mid-week, bringing occasional periods of stormier weather.

All in all, a pretty typical and pleasant summer weather forecast!

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

Stormy Friday Leads to Cooler Weekend

Severe weather is possible across southern Manitoba today as thunderstorms fire up in the afternoon.

Most weather models show strong to severe thunderstorm activity developing over southern Manitoba on Friday afternoon into the evening.

A dynamic weather setup will develop over southern Manitoba today. To begin the day, a warm front lies draped west-to-east across southern Manitoba. Temperatures will warm into the upper 20s this afternoon as a humid air mass pushes northwards out of the Dakotas. A few showers or thunderstorms are possible beginning later this morning, followed by the chance for more potent thunderstorms later this afternoon. All modes of severe weather will be possible, but the main threats will be damaging hail and torrential downpours/flooding. Some thunderstorms may be capable of producing damaging wind gusts. An isolated tornado may be possible too.

Watch for any severe thunderstorm or tornado watches and/or warnings issued by Environment and Climate Change Canada as the day progresses.

The unsettled weather will continue into the evening, then gradually taper off into the overnight period. Temperatures will head down to a low in the mid-teens overnight.

More cloud and unsettled weather will be around for Saturday as an upper low moves through the region. The morning will likely be cloudy with just a slight chance of some showers. Temperatures will climb only to around 20 °C with a strengthening west-northwest wind. As the upper low passes in the afternoon, the region will see a good chance of some more showers swinging in from the northwest. The wind will ease overnight and the showers will taper off as the system tracks off into Ontario. Temperatures will head down to the low teens by Sunday morning.

Finally, mainly sunny skies return for Sunday as a ridge of high pressure moves towards the region. Temperatures will climb into the low to mid 20s with a light northwesterly wind that tapers off later in the afternoon. Temperatures will dip to the mid-teens on Sunday night.

Long Range Outlook

It will be a bit unsettled next week as a relatively active pattern develops over the region. Stormy weather is possible again on Monday, followed by cooler temperatures and calmer weather on Tuesday. Again, Wednesday may bring more showers or thunderstorms that could possibly linger into Thursday. By the end of the week, a pattern of more settled, sunnier conditions should develop.

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

Weather Turning Unsettled This Weekend

Winnipeg will see another day of sunny and mild conditions before cloudier, unsettled weather moves into the region.

RDPS 2m Dew Point Temperature Forecast valid 12Z Monday June 13, 2022
Humid conditions will push into southern Manitoba by the end of the weekend with dew point values climbing into the upper teens.

Today is Winnipeg’s last day under the influence of the upper ridge over the Prairies. After a mostly sunny start to the day, temperatures will climb into the mid-20s for the afternoon. Skies will cloud over through the day as a warm front approaches from the west.

A few showers may be possible this evening, but the activity will weaken though the night. The warm front will stall southwest of the region on Saturday and continue to bring cloud to the region. A few showers may linger across the region early Saturday, but should taper off as the morning progresses.

From Sunday onwards, the upper ridge will slump southwards, allowing multiple disturbances to ride over it across the southern Prairies. While cloud will keep daytime highs in the low to mid-20s, southerly winds will raise dew points into the upper teens. This will give the region the first stretch of humid conditions this summer. Another chance of showers or thunderstorms will develop across the region on Saturday night into Sunday morning. That activity will clear out on Sunday morning, leaving behind mixed to cloudy skies for the rest of the day.

Long Range Outlook

Generally unsettled conditions will persist through the first half of next week as several disturbances roll through the region. A few periods of showers or thunderstorms will again be possible on Monday and Tuesday. Conditions will begin to improve on Wednesday with some sunshine returning the region, but there may be enough lingering instability for a few late-day showers.

Heading into the second half of next week, there’s strong indications that even warmer weather will begin moving into the region. Daytime highs may climb into the upper 20s by the end of next week.

With humid and warmer weather on the horizon, it’s a great time to check to make sure you have some fans in your home and that, if you have it, your air conditioning unit is working correctly. Heat stress is becoming more common in western Canada summers; ensuring that everything works before the warm weather arrives will help protect you. If there are any issues, you’ll likely find what you need easier and cheaper before the heat arrives. If you live alone, think about having someone you might check in with daily this summer during periods of extreme heat, especially if you don’t have access to air conditioning.

It looks like the shift into summer has finally begun; enjoy it! Especially after the winter we just had to endure!

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

Strong Winds as Rain Ends, Seasonably Cool and Dry Conditions Follow

The rain across southern Manitoba will taper off today as very strong northwesterly winds develop across southern Manitoba. Once they ease later today, a stretch of slightly cooler, but mainly dry, conditions takes over.

RDPS 10m Wind Forecast valid 15Z Tuesday May 31, 2022
Strong to severe northwest winds will develop over parts of southern Manitoba early Tuesday morning.

A low pressure system tracking northwards out of Minnesota is the culprit for this latest batch of wet weather across the region. It will continue along the Manitoba/Ontario border today with wrap-around showers lingering through the region into the afternoon. Very strong northwest winds will develop across most of southern Manitoba this morning; sustained winds of 50–60 km/h will spread eastwards this morning, and gusts could reach as high as 80–90 km/h.

The winds will begin to ease later in the day as the low continues off into northern Manitoba. The combination of cloud cover, showers, and that northerly wind will result in a very cool day. Temperatures in Winnipeg will only reach around 10 °C this afternoon. Some clearing will develop tonight as the winds continue to ease to around 20 km/h. Temperatures will fall into the 5–10 °C range.

The weather forecast will be fairly stagnant through the rest of the week. This low moving through will stall out over northern Manitoba for a few days, keeping the weather relatively consistent across the province. Here in Winnipeg, daytime highs will generally sit in the 15–20 °C range with lows in the 5–10 °C range. Northwest winds of 20–30 km/h will be common during the days, but will slowly ease as the system in northern Manitoba weakens through the week. Morning sun with some afternoon cloud will be commonplace.

The only catch might be Thursday; there’s a chance that the Red River Valley is clipped by the remnants of this system as it exits the province. If that happens, Winnipeg would see cloudier conditions on Thursday with a chance of a few showers. It would also be cooler in that situation with highs in the 10–15 °C range.

Long Range Outlook

The end of the week and weekend is looking pleasant overall. Temperatures will nudge back towards 20 °C for the weekend with plenty of sunshine Friday through Sunday.

Today’s seasonal daytime high in Winnipeg is 22 °C while the seasonal overnight low is 8 °C.
