Brad Leave a comment

Summer-like weather will persist through the end of the week, sending September 2021 off with beautiful conditions.

A potent upper-level ridge will bring another hot day to southern Manitoba today. Temperatures will climb up to the 30 °C mark again today with breezy southerly winds near 30 gusting 50 km/h. The region will see plenty of sunshine today despite a bit of cloud building in through the day.

It will be a mild night with a low near 15 °C as the winds ease. A cold front will gradually slide across the Red River Valley overnight, bringing a chance of showers or thunderstorms to the region with it. Most of the activity will likely stay over the western portion of the valley, but a few showers may push eastwards early Thursday. By Thursday morning, Winnipeg will see mostly cloudy skies with a light northwest wind.

Scattered showers and/or thunderstorms will lift northwards through the western Red River Valley along an advancing cold front on Wednesday evening.

The system bringing the unsettled conditions will be tracking eastwards slowly on Thursday, bringing mainly cloudy skies to the region. There will be just a slight chance of an isolated shower or two through the day. Temperatures will be cooler but still well above seasonal averages with a high near 20 °C. The cloud cover should break up on Thursday night as temperatures head to a low near 8 °C.

A ridge of high pressure will bring sun back to the region on Friday. Winnipeg will see light northerly winds and a high near 22 °C. Temperatures will dip to a low near 6 °C on Friday night under mainly clear skies.

Long Range Outlook

The region will see beautiful weather this weekend with highs in the low 20s, partly cloudy skies, and light winds. Lows will sit in the upper single digits. The mild weather will continue into next week.

Today’s seasonal daytime high in Winnipeg is 15 °C while the seasonal overnight low is 4 °C.

Scorching Summer Weather Returns

Temperatures in Winnipeg will soar through the first half of the week as summer returns in full force.

A potent upper-level ridge building over the region will bring temperatures well above seasonal values to wrap up September in southern Manitoba. With plenty of sunshine, temperatures will climb from the mid-20s today to near 30 °C on both Tuesday and Wednesday. Rather unusual for late season heat will be that it won’t be overly windy. The city will see southerly winds up to 30 gusting 50 km/h this afternoon that ease overnight, lighter southeast winds for Tuesday, then southerlies back up to 30 gusting 50 km/h on Wednesday.

Temperatures will climb into the 30s across much of southern Saskatchewan and Manitoba on Tuesday.

A cold front pushing towards the region on Wednesday will bring increasing cloudiness to the city through the day. Skies will stay mostly cloudy overnight with a good chance of showers moving through the region overnight into Thursday morning.

Lows over the coming nights will vary from the low teens to upper teens.

Long Range Outlook

While temperatures will cool behind the cold front, above-seasonal warmth will stay right through into next week. Forecasts show the upper ridge pattern breaking down in the second half of next week, bringing a return to more seasonal temperatures and unsettled conditions.

Today’s seasonal daytime high in Winnipeg is 15 °C while the seasonal overnight low is 4 °C.

Hot And Smoky in Winnipeg

Winnipeg will see more smoky weather as an upper ridge sends temperatures soaring.

Winnipeg will see several days ahead with highs climbing above 30 °C as a potent upper ridge pushes eastwards across the Prairies. With the upper ridge will come broad subsidence and mainly sunny skies over the next few days.

Unfortunately, Winnipeg will continue to see periods of smoke as well. Conditions will likely be worst today, improve for tomorrow, then degrade a bit again on Wednesday.

Winnipeg will see very warm temperatures on Tuesday with highs in the 30s.

Overnight lows will be seasonably warm, though it will be a very warm night on Tuesday night when the warmest air is over the region.

It will stay dry over the next few days, but a few showers or thunderstorms may be possible later Wednesday. A low pressure system will be dropping southwards into the region and may trigger more scattered thunderstorms.

Long Range Outlook

Winnipeg will see a return to seasonal temperatures in the second half of the week with variable cloudiness. There might be a small chance of some showers, but no notable rainfall is likely.

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

More Warm Weather With a Chance of Showers

Brad Leave a comment

Temperatures will stay warm in Winnipeg through the first half of the week and the city may even see a bit of rain.

Today will start off with mixed to cloudy skies as a band of showers makes its way across southern Manitoba. This band developed overnight and may bring some rain to Winnipeg; as of writing, the band hasn’t formed yet so its exact placement is unknown to me!). It will be a narrow band situated just north of an upper-level front draped across the province. There may even be a chance of a thunderstorm. Any rain should push off to the east by midday, leaving the city with partly cloudy skies. Temperatures will climb to a high near 28 °C with northeasterly winds picking up into the 30–40 km/h range.

These winds will tap into some of the forest fire smoke from east of Lake Winnipeg, reducing air quality on Monday night into Tuesday. It shouldn’t be anywhere near as a bad as the last smoke event, but will be enough to be noticeable.

Temperatures will dip to a low near 14 °C tonight with clear skies and easing winds.

An approaching low pressure system will push temperatures higher on Tuesday with the high in Winnipeg in the low 30s. Skies should stay mainly clear for much of the day but some cloud will build into the region by late afternoon. The winds will stay light through the morning, then pick up out of the south into the 20–30 km/h range by the end of the afternoon.

Hot weather will return to southern Manitoba on Tuesday.

Heading into the night, nocturnal thunderstorms will likely develop over western Manitoba and push eastwards. Winnipeg will see a chance for some of that activity overnight into early Wednesday morning. Temperatures will head to a low near 19 °C with southeasterly winds near 30 km/h.

Skies will gradually clear out on Wednesday with northwest winds near 30 gusting 50 km/h and a high near 29 °C. The winds will ease on Wednesday night with a low near 17 °C.

Long Range Outlook

Warm weather will continue for the rest of the week with another chance for some showers or thunderstorms on Friday. After that, temperatures will return to seasonal values with variable cloudiness through the weekend into next week.

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