Spring Arrives

Brad

Winnipeg will finally see pleasant, seasonably mild conditions through the rest of the week.

Winnipeg will shake off the cool grip of winter today as milder spring weather moves into the region. The story for the next few days is short, sweet, and great news for those waiting for conditions to improve.

Temperatures will climb back to seasonal values today with a high near 13°C, but will climb even higher on Thursday into the mid- to upper-teens. A low pressure system exiting northern Manitoba on Friday will send highs back down to a seasonal 13°C. Overnight lows will hover near the freezing mark through the rest of the work week.

Long Range Outlook

The weekend should bring much of the same weather with seasonal temperatures continuing. Beginning Sunday night into the first half of next week, conditions may turn more unsettled with several chances for rain.

Today’s seasonal daytime high in Winnipeg is 13°C while the seasonal overnight low is 0°C.

Cool with Snow to Start, But Spring Arrives Mid-Week

Brad Leave a comment

Winnipeg will have a cool and unsettled start to the week, but warmer spring conditions are on the way.

A cold front slumping southwards today will bring cool temperatures and mostly cloudy skies to Winnipeg. Northwest winds up to 30 gusting 50 km/h will keep temperatures to a high of just +3°C. A few flurries will be possible midday through the afternoon as general instability develops over the region. The clouds will clear out this evening with diminishing winds. A ridge of high pressure moving through overnight will send lows down to -10°C by Tuesday morning.

Another low pressure system will slide through the southeastern Prairies on Tuesday. While it will bring mild conditions to southeastern Saskatchewan and southwestern Manitoba, it will be much cooler in the Red River Valley. Highs will again sit near +3°C with breezy south-southeast winds of 30 gusting 50 km/h. Skies will cloud over in the morning as the low pushes into the southwest corner of the province, followed by some light snow through the afternoon hours. The winds will taper off in the evening with some fo the cloud cover breaking up. Temperatures will dip to a low near -2°C.

On Tuesday, a low pressure system will produce a swath of snow that moves from west-central Manitoba southeastwards into the Red River Valley.

Wednesday will mark the beginning of The Turnaround®. A more zonal flow will develop across the Prairies as the west coast upper ridge begins to collapse, allowing milder Pacific air to push eastwards. Winnipeg will see a high near +9°C with mixed skies and light winds. Skies will stay mixed on Wednesday night with a low near +2°C.

Long Range Outlook

The rest of the week finally looks to bring pleasant spring weather. With partly cloudy to mixed skies, Winnipeg will see several days of highs in the mid-teens with light winds. There may be a chance of showers (or perhaps even thunderstorms) in the second half of the week, currently looking like possibly on Wednesday night into Thursday morning. Even warmer weather looks likely for the weekend with highs climbing into the upper teens.

Today’s seasonal daytime high in Winnipeg is 12°C while the seasonal overnight low is 0°C.

Mild Friday Followed by Cooler, Unsettled Weekend

Brad

Spring weather arrives in Winnipeg today with plenty of sunshine and a return to seasonal temperatures. The weekend will bring unsettled conditions as a pair of disturbances move through.

Seasonal temperatures will return to Winnipeg today as a breezy southwest wind pushes milder Pacific air back into the region. Winds will strengthen to 30 gusting 50 km/h through the morning under sunny skies. As a low pressure system moves towards the province from the northwest, a few clouds will begin to arrive through the afternoon.

Seasonal temperatures will return to Winnipeg today thanks to a breezy southwest wind.

Skies will cloud over this evening as the low moves through the region, bringing with it a chance of showers. Winds will ease, then shift northwesterly overnight as a cold front swings through. The cloudy conditions will persist on Saturday with a lingering chance for showers gradually tapering off. It will be cooler on Saturday as northwest winds of 30 to 40 km/h limit temperatures to just a couple degrees above tonight’s low.

Skies will clear out later on Saturday afternoon, then winds will ease and temperatures will dip below freezing on Saturday night.

Another low pressure system will approach the region on Sunday, bringing increasing cloudiness and breezy west-southwest winds again. Temperatures will again climb into the mid-single digits. By the afternoon, a chance of showers will develop, but much of the precipitation is forecast to fall north of the area. Much of the cloud will stick around on Sunday night with a continued chance of showers or flurries.

Long Range Outlook

Conditions will improve next week when a more sustained period of seasonal temperatures moves into the region. A westerly flow will bring several disturbances across the province through the week, resulting in variable cloudiness and a few chances for rain.

Today’s seasonal daytime high in Winnipeg is 11°C while the seasonal overnight low is -1°C.

Cool Weather And Flurries Easing Friday

Milder spring weather will return to Winnipeg after a couple more cool days.

A brisk northwest wind of 20 to 30 km/h will keep daytime highs nearly 10°C below normal over the next couple days in Winnipeg. The city will see variable cloudiness today and tomorrow – partly cloudy skies today and mixed skies tomorrow – as the spring sunshine continues to produce convective cloud over the region. The low-level instability in the cool air will continue to bring a chance for some light flurries both days.

Overnight lows will dip into the -5 to -10°C range.

A low pressure system will spread seasonal temperatures eastwards into Manitoba on Friday.

On Friday, a warm front pushing through the province will usher in a milder Pacific air mass. Highs will return towards seasonal values near 10°C with breezy southwest winds of 20 to 30 km/h. Fortunately it’s a fairly dry air mass, so the region should see plenty of sunshine. Near the western escarpement, winds will be a bit stronger with gusts up to 60 km/h.

Long Range Outlook

Winnipeg will see a cloudier weekend with highs in the mid-single digits as a series of disturbances move through. There will be a couple chances for precipitation through the weekend as well. Settled conditions with temperatures rebounding back towards seasonal values will develop early next week.

Today’s seasonal daytime high in Winnipeg is 10°C while the seasonal overnight low is -2°C.
