Get The Sunscreen Out: Summer’s Back

Brad 1 Comment

Here comes the shortest forecast we’ve written in a while: summer is making a big comeback in Winnipeg as the forecast — both short and long-range — holds practically nothing but sunshine and warm temperatures.

Winnipeg will see a trio of beautiful days ahead as two features keep skies clear and slowly warm things up. The first is an upper-level ridge over Manitoba and the second is a high pressure system in Ontario that continues to exert its influence over southern Manitoba. These two features combined together will keep things sunny, and as the surface high slowly moves off to the southeast, temperatures will climb back into summer-like values.

The jet stream lifts far to the north of Winnipeg, creating an upper-level ridge that is producing clear skies over the eastern Prairies.

So both today and Saturday will bring nothing but sunshine to Winnipeg & the Red River Valley with high temperatures of 23°C today and 26°C on Saturday. Winds will be out of the south both days, to around 20-30 km/h today and 30-40 km/h on Saturday. Expect lows near 9°C tonight and near 15°C on Saturday night.

We could see a few clouds on Sunday morning, but overall the day should be fairly sunny. The only fly in the ointment could be a thick layer of smoke spreading in from the west. Temperatures may reach as warm as 30°C, but if there ends up being a lot of smoke it could be a few degrees cooler than that. Winds will continue out of the south at around 30 km/h. A cold front will swing through on Sunday night, bringing some clouds and a chance of showers to the region, however no significant rain is expected with the passage of the front.

Long Range

Monday looks to bring mixed skies and lighter winds in the wake of the cold front with temperatures slightly cooler than Sunday. Things then clear out for Tuesday and temperatures continue to remain above-normal through mid-week. A disturbance developing over the Prairies on Wednesday into Thursday will then likely begin bringing more seasonal temperatures, increased cloud, and a chance of showers back to the Red River Valley for the end of the week.

The biggest question mark will be how much smoke ends up in the region, though. With westerly winds, a fair amount of the B.C. forest fire smoke may end up making its way here, and early indications are that there is the potential for it to be the most significant smoke event for Winnipeg so far this year. We’ll be keeping an eye on it!

Winnipeg’s seasonal daytime high is currently 20°C while the seasonal overnight low is 7C.

Warm and Dry Weather on the Horizon

An upper-level ridge building into the Prairies will spread significantly warmer-than-seasonal temperatures back into the region while keeping the rain well away.

Winnipeg has quite the stretch of warm, dry weather ahead as an upper level ridge builds eastwards through Alberta and into the eastern Prairies over the next couple days. That said, it makes for a pretty short forecast.

Today will bring mixed skies as some cloud moves into the region associated with the warmer air moving in aloft. Winds will be light and temperatures will head to a high near 21°C. Clouds will stick around through the night as temperatures head to a low near 10°C.

Thursday will bring partly-cloudy skies to Winnipeg with a high around 22°C and a light northeast wind. The clouds should clear out by the evening and then temperatures head to a low near 8°C.

And for Friday, nothing but sunshine as highs climb to around the 23°C mark as winds pick up to around 15-20 km/h out of the south. Expect a low near 12°C on Friday night under clear skies.

Long Range

The warmth intensifies on the weekend with highs in Winnipeg climbing into the upper 20’s with a slight chance of even seeing a 30°C reading on Sunday. A cold front will move through on Sunday evening bringing a slight chance of a shower or thunderstorm, but then things go right back to sunny with warmer-than-seasonal temperatures continuing!

Winnipeg’s seasonal daytime high is currently 20°C while the seasonal overnight low is 8C.

Warm and Dry Weather Ahead

An upper-level ridge slowly building eastwards across the Prairies will bring generally sunny and increasingly warm weather to Winnipeg and the Red River Valley. For those who like summer weather, the next 5 days will be pretty much perfect!

The upper-level ridge that has been anchored over British Columbia over the past week will begin pushing eastwards, shifting the omega block pattern from the west coast to over the Prairies. This will spread mild weather over the Prairies and, eventually, break the persistent northerly winds that have been in place over the province and return a southerly flow that will bring humid conditions back to the region next week.

By Sunday, the omega block will be situated over the central Prairies, however parts of Southern Manitoba will see some cloud as an upper low tracks through North Dakota.

So, for the coming few days, the forecast will be straightforward with daytime highs of 26 or 27°C and overnight lows in the 13-15°C range. Winds will be light over the next 3 days and there will be plenty of sunshine. Sunday may bring a few more clouds as an upper-level low passes by to our south, but even then we expect things to remain dry.

Long Range

Looking into the beginning of next week, things start off quite warm with highs climbing into the upper 20’s and overnight lows creeping up into the high teens. A trough of low pressure will begin building across the Prairies Monday night, bringing southerly winds into the region on Tuesday that will gradually ramp up the humidity. As it stands now, it appears that by the end of Tuesday dew points will climb to around 17°C, bringing slightly muggy weather back to the region.

A chance of showers or thunderstorms then returns to the region on Tuesday night into Wednesday and marks the transition into a few days of potentially unsettled weather. Temperatures will remain warm, though with highs continuing in the mid- to upper-twenties.

Winnipeg’s seasonal daytime high is currently 26°C while the seasonal overnight low is 12°C.

Get The Sunscreen Out; Plenty of Summer Sun & Heat On The Way

A beautiful second half to the week is ahead for Winnipeg as an upper-level ridge building into the Prairies brings plenty of sun and warmth to the area!

It’s been a while, but the forecast today is finally short once again. The next few days will be great across Winnipeg and the Red River Valley as upper-level ridging clears skies and ushers warmer weather back into the region. Today will bring highs near 26°C to Winnipeg and area with mainly sunny skies until late in the afternoon. A very weak upper-trough moving through late in the day will bring a few clouds to the region and perhaps trigger an isolated evening shower, but the main chance will be north of the city and it’s not expected that Winnipeg or areas south have much of a chance of seeing any rain.

The RDPS shows some isolated showers, mainly through the Interlake, late today in to the evening.

Temperatures will head to a low near 16°C tonight. Thursday and Friday will both be mild with high temperatures climbing towards 30°C on Friday. Both days will have plenty of sun; Thursday should bring nothing but sunshine while Friday brings partly cloudy skies. Winds will be out of the northwest today at 15-25 km/h, light on Thursday, and then increase out of the south on Friday to 20-30 km/h. Temperatures will dip down to around 17°C on Thursday night, but Friday will see a warmer overnight low near 20°C.

Long Range

Warm weather will continue throughout the weekend. A low pressure system moving through the Prairies on Saturday will bring increasing humidity and a risk of thunderstorms to much of Manitoba. For Winnipeg and the Red River Valley, the risk for storms will likely be in the late-afternoon and evening. Sunday will see northerly winds usher in drier air while temperatures return to near-seasonal values.

Next week looks to bring near-seasonal temperatures with a slight chance of some thunderstorms on Tuesday and Wednesday.

Winnipeg’s seasonal daytime high is currently 26°C while the seasonal overnight low is 13°C.
