Winnipeg will see seasonably cool conditions last through the first half of the weekend, then warmer weather arrives on Sunday.

A series of Arctic ridges will move through over the next couple days, keeping temperatures cool across southern Manitoba. Both Friday and Saturday will bring daytime highs near 10 °C in Winnipeg and lows dipping just below freezing. The city will see light southerly winds today switching to light northerly winds on Saturday.

The city will see mixed to cloudy skies today as the cloud associated with a low to the west slumping into the Dakotas clips through the Red River Valley. The rest of the weekend will see partly cloudy skies return. There’s a small chance of an isolated shower or snow flurry overnight Friday into Saturday morning. Otherwise, the weekend should be dry.

On Sunday, an approaching low will usher in moderate southerly winds of 30–40 km/h and bring temperatures back up to a near-seasonal 12°C. This will mark the beginning of a stretch of near-seasonal temperatures that should last right through the coming week. With a warmer air mass in place, overnight lows on Sunday night will be much warmer, bottoming out around 8 °C.

Long Range Outlook

Next week will start off with some cloud on Monday, but then bring partly cloudy conditions through much of the rest of the week. Temperatures look to be fairly steady with highs in the mid-teens and lows in the 5–10 °C range. No notable precipitation is forecast for the city, however areas further north could see several chances for rain through the week.

Today’s seasonal daytime high in Winnipeg is 14 °C while the seasonal overnight low is 3 °C.

A weak disturbance will bring slightly cooler and cloudier weather to Winnipeg on Wednesday, but mild temperatures quickly return.

Two features will combine to bring a change in the weather to Winnipeg today. The first is a large area of high pressure tracking across the Prairies that will sprawl across Manitoba today. It will bring dry northerly winds of 20–30 km/h to the region today and cooler highs in the upper teens. The second is a weak mid-level disturbance that will move through the area. It will spread cloud cover into the Red River Valley through the morning and bring a chance of showers for the afternoon hours.

Skies will clear out in the evening with easing winds. A ridge from the high pressure system over the province will move into the Red River Valley overnight, sending lows to a seasonably chilly +3 °C.

The warm weather quickly returns to the region on Thursday as another low begins pushing eastwards across the Prairies. Winds will pick up out of the south into the 20–30 km/h range in the afternoon as temperatures climb to a high near 23 °C. A warm front will approach through the day, bringing partly cloudy skies to the region.

Skies will stay cloudy overnight with a chance of showers as a trough and cold front successively move through the area. The combination of cloud cover and persistent south wind will keep temperatures mild with a low near 14 °C.

Friday will be another warm day in Winnipeg. The city will see a high near 24 °C with a westerly wind near 20 km/h and partly cloudy skies. Not much else to say about the day; it’ll be a nice one! Temperatures will dip to a low near 10 °C under partly cloudy skies on Friday night.

Long Range Outlook

Winnipeg will see a mild weekend with highs near 20 °C and lows around 9 °C. Both Saturday and Sunday should bring partly cloudy skies with a slight chance of rain showers on Saturday. On Sunday night, a low will begin moving through the region, bringing rain through the region and ushering in strong northerly winds and a return to seasonal temperatures.

Today’s seasonal daytime high in Winnipeg is 16 °C while the seasonal overnight low is 5 °C.

Temperatures will warm up for the weekend, kicking off an extended period of seasonably mild temperatures.

Near-seasonal temperatures will return to Winnipeg today as a warm front pushes eastwards across the province. This front will also bring cloud cover with it, replacing morning sun with cloudy periods by midday. The city will see a high near 16 °C this afternoon with southerly winds of 20–30 km/h. Skies will clear by the evening as the front pushes off to the east. The winds will keep up near 20 km/h tonight and it will be a much warmer night with a low near 8 °C.

On Saturday, the region will see mainly sunny skies and light southerly winds. Temperatures will climb to a seasonably mild high of 23 °C. There may be a bit of high-level forest fire smoke, but most dispersion models show the denser plume of smoke lifting into the central and northern Prairies. Winnipeg will see a low near 13 °C on Saturday night as winds pick up out of the southeast to 30 km/h. Some cloud cover will begin to push into the region overnight as a low approaches from the west.

Winnipeg will see mixed to mostly cloudy skies on Sunday as a low pressure system pushes into the province. Moderate southerly winds of 30–40 km/h will persist through the day as temperatures climb to a high near 24 °C. A few showers will move into the region, but most will weaken moving into the Red River Valley. The cloud cover will break up in the evening as a trough moves through, then temperatures will dip to a summer-like 16 °C with a chance of showers early Monday morning.

Long Range Outlook

Next week will continue to bring seasonably mild temperatures to Winnipeg with highs largely staying in the 20–25 °C range. A few chances of showers will occur through the week, but it looks like great end-of-September weather.

The one unknown heading into next week will be how much of the West Coast wildfire smoke moves into the region. Details on that should become more clear as the weekend progresses.

Today’s seasonal daytime high in Winnipeg is 17 °C while the seasonal overnight low is 6 °C.
