Rain will taper off in the Winnipeg area this morning, leaving behind cold conditions as the region begins to dry out.
Very cool temperatures will flood the eastern Prairies in the wake of the departing rain.
Rain will taper off this morning in the Winnipeg area and leave behind mostly cloudy skies. Moderate northerly winds near 40 gusting 60 km/h will stick around through the day, flooding the region with much cooler air. Daytime highs will struggle to reach even our seasonal overnight low in Winnipeg; the city will top out at around 6 °C.
Conditions will improve in the evening as the wind begins to taper off and some clear breaks develop. It will be a cold night with lows dipping to around the freezing mark. Frost will be possible, especially in outlying areas, overnight.
After that, conditions will be on the up and up. Mixed skies on Saturday will give way to sunshine on Sunday, and daytime highs will climb by around 5 °C per day. Saturday’s high will be near 10 °C and Sunday should reach the mid-teens. Overnight lows will also ease towards the mid-single digits. With the sunshine on Saturday, a few scattered showers will be possible in the afternoon.
To start of next week, Monday will bring partly cloudy skies with a high in the 15–20 °C range. Overnight lows will climb into the 5–10 °C range for the start of next week.
Long Range Outlook
Next week begins to look decidedly more summery for southern Manitoba. Daytime highs will finally return to more seasonal values, sitting in the 20–25 °C range for most of next week. A few chances for some scattered thunderstorms are possible next week, but no widespread significant rain is in the forecast. Overall, it looks like a shift back towards more seasonal conditions with an opportunity to dry out.
Today’s seasonal daytime high in Winnipeg is 21 °C while the seasonal overnight low is 6 °C.
After a windy day today, conditions will settle down with a stretch of cooler and drier weather ahead.
Cooler conditions will settle into the eastern Prairies in the wake of Friday’s passing low pressure system.
With the overnight rain now well to the north, the weather in Winnipeg today will be marked by the passage of a strong low pressure system to the west. As it lifts northwards, southerly winds will strengthen over the Red River Valley. Most areas will see winds as high as 50–60 km/h this afternoon with gusts up to 80 km/h possible. Skies will stay mostly cloudy through the morning, with more breaks in the cloud developing this afternoon. Conditions should be drier though, with just a chance of some scattered afternoon showers. Temperatures will hover in the low teens through the day today.
The low will push off into northern Manitoba tonight, bringing a bit of clearing into the region as the winds ease to around 30 gusting 50 km/h. Temperatures will dip down to the upper single digits. Some more cloud will push back into the region later on Saturday as an upper-level disturbance skirts along the border. This will also bring a few showers to the region that taper off in the evening. It will be another breezy day with southwesterly winds of 30–40 km/h.
Temperatures will be cool on Saturday and for several days after that. A northwesterly flow will usher in a high pressure system from the Arctic over the next few days. Daytime highs will be well below seasonal, particularly on Sunday and Monday. Daytime highs will struggle to climb much higher than 10 °C on either of those days. Overnight lows will also dip into the low single digits, with even a chance that we might dip below freezing on Monday night. The upside to the cooler conditions is that it will also bring drier weather. No significant rain is in the forecast for the next several days.
Long Range Outlook
Temperatures will begin to creep back towards seasonal values in Winnipeg towards the middle of next week. Showers will be possible through the second half of the week, but at this point it doesn’t look like they’ll produce very significant amounts of rain for the region.
Today’s seasonal daytime high in Winnipeg is 19 °C while the seasonal overnight low is 5 °C.
Southern Manitoba will see a mix of weather this week with more rain on Thursday.
Southern Manitoba will see another soaking on Thursday with a widespread 15–30 mm of rain across many areas and some locally higher accumulations.
The region will get a bit of a chance to dry out today, a welcome change after the 15–25 mm of rain seen across most of the region yesterday. Sunnier skies will send highs near 20 °C, but it will be windy this afternoon. Southwest winds will pick up into the 40–50 km/h range this afternoon.
The winds will taper off this evening as a ridge moves across the region. Lows will dip into the upper single digits. More cloud will push into the region early Wednesday morning as a push of warmer air begins moving in aloft from the Dakotas.
Wednesday will bring cloudy skies to the region with a chance of showers a warm front slowly continues northwards towards southern Manitoba. Temperatures should climb into the upper teens with northeast winds picking up to 20–30 km/h through the afternoon. A few sunny breaks might materialize later in the day, but skies will cloud back over in the evening.
The next storm system to impact the region will begin its approach on Thursday night. It will spread showers and thunderstorms into the Dakotas as it moves northwards, reaching the Manitoba border by Thursday morning. A broad area of rain will move through the region on Thursday, bringing another 15–30 mm of rain to the Red River Valley. A few embedded thunderstorms will be possible and could result in locally higher rainfall accumulations. A more organized thunderstorm threat will develop late in the day, but will highly likely be for southeastern Manitoba into MN/ND. The rain will taper off by Thursday evening with just a few lingering showers hanging around until Friday morning. Temperatures will sit in the mid-teens on Thursday with breezy northeast winds.
Some sunshine will poke through later on Friday with temperatures climbing back towards the 20 °C mark. Moderate southwesterlies will develop through the day, climbing into the 40–50 km/h range.
Long Range Outlook
Cooler temperatures will build into the region for the weekend in the wake of this next storm system. Highs will fall into the 10–15 °C range with mixed skies over the weekend. Warmer weather will begin building back into the region near the middle of next week. Fortunately, it doesn’t look like any frost is in the forecast; overnight lows should drop only to the mid-single digits.
Today’s seasonal daytime high in Winnipeg is 18 °C while the seasonal overnight low is 4 °C.
Temperatures will stay mild in Winnipeg through the weekend, but sunshine will give way to more chances for showers.
Summer-like warmth will spread through southern Manitoba on Saturday.
Warmer weather will continue to push into the Red River Valley over the coming days. Daytime highs will stay in teh 20s, reaching close to the mid-20s on Saturday. This push of warmer weather is thanks to a stubborn low pressure system over the northern Prairies. It will support a southerly flow over the southeastern Prairies, drawing a consistent stream of milder air northwards. With that, though, will also come several disturbances that will also move north in the flow.
After a plenty of sunshine day today, a broken line of showers will push across the Red River Valley. Supported only by a weakening trowal, the showers won’t likely amount to much. Skies will clear out overnight as temperatures dip into the low teens.
Saturday will be a slightly more interesting weather day across the region. Off to a sunny start, the day will warm up quickly. Winnipeg should reach 20 °C by noon, and climb close to 25 °C in the afternoon. Of note will be that it will become quite windy in the afternoon with strong southerly winds of 50–60 km/h. This will be particularly concerning as the winds will generate significant wave action on the flood waters through the valley. This will produce stress on flooded roads and flood barriers in place; consult local EMOs on whether you might need to take any additional action to reinforce any personal flood protection structures.
Later in the day, cloud will push into the region as a low pressure system lifts from eastern Montana into western Manitoba. This low will support an area of rain that moves through southeast Saskatchewan into western Manitoba through the day.
For our region, showers will likely develop late in the day as a cold front starts pushing eastwards towards the Red River Valley. By evening, the forcing of the cold front will combine with a strengthening low-level jet, triggering a line of showers and thunderstorms. The storm environment is even relatively supportive for this time of year. As long as the forecasted moisture advection from the American Plains is able to materialize, the storms will have a moderate amount of energy to work with and ample wind shear to organize it.
The storms will likely trigger close to the Saskatchewan border, then move east-southeast. Some of these storms may be severe with the potential for damaging hail and strong wind gusts. As the line approaches the Red River Valley, it will dig into the low-level jet, developing southwards. As a result, the storms in Manitoba will weaken as they head into the Red River Valley, making it more likely that our area sees some collapsing showers or weak thundershowers, although stronger storms could linger closer to the U.S. border.
Thunderstorms are likely over southwestern Manitoba on Saturday afternoon, pushing towards the Red River Vally into the evening hours.
Temperatures will drop down to around 10 °C on Saturday night. Showers will be possible through the night.
On Sunday, the region could see some morning showers but its highly dependent on the evolution of this system. The rest of the day will bring mixed skies to the region as we sit on the edge of a system passing to the east. Temperatures will still be mild with highs in the upper teens.
Long Range Outlook
On Monday, another disturbance will move into the province bringing more showers and a risk of thunderstorms to the region. After that, a couple nice days are in store, then another chance of showers or thunderstorms will develop later in the week.
Today’s seasonal daytime high in Winnipeg is 17 °C while the seasonal overnight low is 3 °C.
