Seasonal temperatures will return to much of Manitoba by the latter half of the week.

Today will bring cloudy and cool weather to Winnipeg. The main weather feature will be a band of rain stretching from a low pressure system crossing the American Plains into southwestern Manitoba and eastern Saskatchewan. This will likely bring showers to the southern Red River Valley today while Winnipeg will have a chance of seeing rain if it ends up grazed by the eastern edge of the precipitation as it pushes northwest.

The cloudy weather will come alongside easterly winds of 20–30 km/h and a high in the mid-teens. Rainfall totals will likely range from anywhere from as much as 10 mm of rain over the far southwestern Red River Valley to a trace of rain further northeast.

Temperatures will dip down into the mid-single digits as the cloud cover breaks up overnight.

Wednesday will bring a building ridge of high pressure into the region. This should bring partly cloudy skies to the region with light easterly winds. With more sunshine, temperatures will climb higher than today, topping out in the upper teens. Wednesday night will bring clear skies and temperatures dipping down into the mid-single digits.

Thursday will bring mainly sunny skies and a high near 20 °C. Winds will pick up out of the northeast to around 20 km/h for much of the day. The winds will shift southeast overnight as temperatures head to a low in the 5–10 °C range.

At this point, it doesn’t appear that smoke will be much of an issue in the days ahead. The recent rain and cooler weather has dampened the fire activity in southeastern Manitoba. We’ll monitor the fires through the week as conditions dry out and the weather begins to warm again.

Long Range Outlook

The weather looks benign into the weekend the weekend with variable cloudiness and highs hovering near the low 20s. Overnight lows will sit in the 5–10 °C range.

A push of warmer weather along with a chance of showers or thunderstorms is possible later next week.

Today’s seasonal daytime high in Winnipeg is 21 °C while the seasonal overnight low is 6 °C.

More Warm Weather Ahead in Winnipeg

Wednesday evening’s Whiteout Street Party will start with pleasant temperatures in the upper teens in downtown Winnipeg.

Seasonal temperatures return to the Red River Valley today behind a cold front that moved through the region overnight. Northerly winds will continue through the day near 30 gusting 50 km/h as temperatures climb to a high in the upper teens. The wind will die off tonight as a ridge of high pressure moves in and sends temperatures down into the low single digits.

An upper ridge will begin to build back across the Prairies mid-week, bringing more sunshine and warmth to the region. On Wednesday, temperatures will climb to around the 20 °C mark with light southeast winds developing in the afternoon.

Wednesday evening’s Whiteout Street Party for Game 1 against the Dallas Stars should see temperatures near 16 or 17 °C at puck drop that cool to around 11 °C by the end of the game. The low overnight will dip down into the upper single digits under clear skies.

Warmer weather returns for Thursday as daytime highs climb into the mid- to upper-20s as southerly winds of 30 to 40 km/h redevelop over the region. Those southerly winds will ease and turn northerly on Thursday night as a weak cold front pushes through the region. It may bring clouds and a chance of showers overnight into early Friday morning. Temperatures will head to an overnight low in the low teens.

Long Range Outlook

Friday and Saturday are looking like they will bring seasonal to mild temperatures to the region along with an end to the sunny skies with cloud cover possible later Friday into Saturday. Showers may be possible Saturday night as warmer air pushes into the region. Sunday will be another hot day with highs in the upper 20s possible. That heat will likely build into Monday and bring the chance for Winnipeg’s first 30 °C day of the year.

For Friday’s Whiteout Street Party, the weather should be similar to Wednesday with the only notable difference being a more noticeable northerly breeze. Which, to be honest, will likely be low down on the “things to notice” list if you’re planning on heading downtown for the game.

Go Jets go!

Today’s seasonal daytime high in Winnipeg is 17 °C while the seasonal overnight low is +3 °C.

This weekend will bring the warmest weather so far this year to southern Manitoba.

Winnipeg has had a couple mild days this spring, but none that will compare to the heat that builds into the region this weekend. With a cooler Thursday behind us, yesterday’s northerlies will be replaced with light westerlies as milder Pacific air begins to push east. Today will trend cooler with a high in the low teens as the region transitions out of the colder air that moved into the region. While the day will start with cloud in the region, it should break up and move out for the afternoon.

Temperatures will dip into the 5–10 °C range tonight under clear skies as light winds shift southerly.

Heading into the weekend, the early-season heat is on with mainly sunny skies through the weekend. Saturday will bring daytime highs into the mid-20s while Sunday will likely be warmer with highs in the mid- to upper-20s . Winds will shift westerly through Saturday but should remain light. On Sunday, the winds will strengthen from the south to as high as 40 gusting 60 km/h. Those winds will ease into the 20 to 30 km/h range on Sunday night. Overnight lows in both nights should sit in the 10 to 15 °C range.

Long Range Outlook

The warm weather will stick around for Monday, then ease to seasonal values for a couple days before more heat builds back into the region. No significant precipitation is in the forecast.

Today’s seasonal daytime high in Winnipeg is 16 °C while the seasonal overnight low is +2 °C.

Gradually Warming up in Winnipeg

Temperatures will gradually warm through the week in Winnipeg, bringing beautiful spring warmth to the region by week’s end.

A building upper ridge will bring warm weather to western Canada this week, gradually pushing it east into southern Manitoba.

Sorry about the delay in posting; life has been busy and we’ll go with better late than never!

Looking ahead through the rest of the work week, the weather in Winnipeg will see a distinct warming trend as an upper ridge builds over western North America. Before that warmer weather gets to southern Manitoba, though, a weak disturbance will move through the region.

This disturbance will push cloud cover into the region overnight as temperatures dip down to a low near the freezing mark. Light snow is possible by Wednesday morning. Periods of light snow will likely transition to a few rain showers through the day on Wednesday as temperatures climb up to a high near 5 °C. Winds won’t be too much of an issue, climbing to around 20 km/h out of the southeast for the afternoon.

Skies will stay cloudy on Wednesday night as the winds taper off. Temperatures will head down to a low near the freezing mark.

On Thursday, a surface high pressure will build into the province as the upper ridge begins to amplify over western Canada. Cloudy skies will gradually break up through the day with clearing pushing into the region by the evening. Winds will stay light as temperatures climb to a high in the 5 to 10 °C range. Temperatures will dip down into the -5 to 0 °C range overnight under clear skies.

Long Range Outlook

Friday will bring mixed skies to the region as temperatures climb into the mid-teens. The warmth will come with breezy southerlies up to around 40 km/h that gradually taper off on Friday night. Temperatures will likely dip down into the 5 to 10 °C range on Friday night.

There’s more uncertainty in the weather heading into the weekend. A potent low pressure system will develop in the United States push northeast, but it’s unclear if it will end up affecting southern Manitoba or track further east into NW Ontario. It has the potential to bring significant precipitation to the region, but there’s a wide range of solutions that change day by day.

It does look likely that Winnipeg should see a high in the teens again on Saturday, then cool into the single digits for Sunday. There may be rain or snow beginning on Sunday, but that will be dependent on the track of the system south of the border. We’ll keep track of this system’s development through the week and have more to say on Friday.

Until then, enjoy the warmth heading our way!

Today’s seasonal daytime high in Winnipeg is 8 °C while the seasonal overnight low is -3 °C.
