Pleasant Weekend Ahead

Winnipeg will see a pleasant spring weekend ahead with plenty of sun and daytime highs near 20°C.

A high pressure system gradually moving into the province over the coming days will bring sunshine and seasonably warm temperatures. Winds will be out of the northwest at around 20 km/h today under mainly sunny skies with a high near 20°C. A few clouds will move into the region tonight as a weak disturbance rolls through, bringing just a slight chance of showers to the region through the overnight hours. Temperatures will dip down to around 5°C for the low.

Winnipeg will see partly cloudy skies this weekend with daytime highs close to the 20°C mark. Winds on Saturday will be out of the north at around 20 km/h as the high pressure system approaches. On Sunday, winds shift to light out of the south as the high exits the province. Saturday will bring another seasonal low near 4°C, but warmer air building into the region on Sunday will keep lows much warmer on Sunday night. Winnipeg should see a low around 10°C heading into Monday morning.

Long Range Outlook

Next week continues to look seasonably warm, however Winnipeg may finally begin to see the chance for some much-needed rain. Forecasts show the storm track pushing northwards out of the United States into the southern Prairies with the  potential for rain or thunderstorms Monday night into Tuesday. This chance repeats again on Friday or Saturday as another low moves through.

Unfortunately, these systems will be driven largely by convection, making forecasts this far out practically useless. It’s safe to say that it will be a bit more unsettled and Winnipeg will see more cloud next week; we’ll have to wait and see if that translates into rain.

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

Beautiful Weekend Ahead for Winnipeg

Winnipeg will see a cool Friday to round out the work week, but sunshine and warm temperatures return for the weekend.

Temperatures will be cool today as Winnipeg remains in cool air brought south behind yesterday’s cold front. Skies will cloud over early this morning then clear sometime mid- to late afternoon. Winnipeg’s high temperature will only reach around 12°C, tempered by cool northwesterly winds of 30 gusting 50 km/h that will persist until evening.

Tonight will be chilly as a ridge of high pressure brings clear skies and a low near -1°C.

An upper-level ridge will build into the Priaries this weekend, bringing warmer temperatures.

Things turn around quickly for the weekend though. An upper ridge building into the Prairies will bring sunny skies both Saturday and Sunday. Southerly winds will draw warmer air into the region with highs reaching 15°C on Saturday and a mild 23°C on Sunday. Winds will become more pronounced as the weekend progresses. Saturday will see southerly winds strengthen to 20 to 30 km/h. Sunday will bring southerly winds of 30 to 40 km/h.

Long Range Outlook

As we’ve mentioned several times over the past week, the beginning of next week will see a rather complex low pressure system lift out of the northern Plains into the Prairies. Details are still hazy, but the general idea is beginning to come into focus.

At this point, it looks like Winnipeg will see a chance of showers or thunderstorms on Monday morning. Most models are showing an area of thunderstorms developing over southeastern Saskatchewan on Sunday night that spreads eastwards. There’s still significant uncertainty in exactly where everything will set up, but in general Winnipeg will see cloudier, unsettled weather on Monday and Tuesday.

Winnipeg’s seasonal daytime high is currently 15°C while the seasonal overnight low is 2°C.

Warm and Windy Weather On The Way

Breezy conditions will develop over the Red River Valley this weekend as temperatures climb to above-seasonal values.

A low pressure system tracking through the northern Prairies will be the main driver for Winnipeg’s weather over the next several days. As it develops in Alberta and moves eastwards, warmer temperatures will spread across the southern Prairies. Daytime highs will sit comfortably in the mid-teens today, then climb into the upper teens for both Saturday and Sunday. This weekend’s mild temperatures will be matched by increasing winds out of the south to around 30 gusting 50 km/h by Saturday afternoon.

These warmer daytime highs will be matched by overnight lows climbing to above-seasonal values, particularly on Saturday night where southerly winds of 20 to 30 km/h will help produce a mild low near 6°C.

Of particular note, alongside the temperature, the dew point temperature will also be increasing. This value is a measure of how much water is in the air.  Not only is it important summer-focused weather such as thunderstorms, it also has major impact on the spring snow melt. Dew point temperatures will climb above 0°C on Saturday, combining with the mild temperatures to speed up the melting of any remaining snow in the Red River Valley.

Skies will be variably cloudy over the next couple days. Winnipeg will see mixed today, but Saturday will bring more sun with just partly cloudy skies. Winnipeg should see sunshine Sunday morning change to mixed skies in the afternoon as a cold front moves through.

There is a chance of a passing shower as the cold front swings through on Sunday, otherwise conditions look dry.

Long Range Outlook

More of the same in the long range: seasonal to above-seasonal temperatures and variable cloudiness. No big rainfall events are on the horizon. With continuing mild temperatures drying out the ground, all should be aware of the increasing fire hazard heading into the end of the month.

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

Variable Cloudiness, Above-Seasonal Temperatures Ahead

This week is shaping up to be pleasant in Winnipeg with variable cloudiness and slightly above-seasonal temperatures.

Winnipeg will remain under the influence of a stationary high pressure system for the rest of the week. The result will be dry conditions with pleasant temperatures and variable cloudiness lasting into the weekend.

Temperatures over the coming days will trend to slightly above-seasonal values. Winnipeg will see highs in the low teens and overnight lows near 0°C as milder air gradually spreads across the Prairies. Thanks to the stationary high pressure system, winds will remain relatively light over the region. Wind speeds should remain around the 10 to 20 km/h range while the direction backs from northeasterly today to westerly on Thursday to southerly on Friday.

Long Range Outlook

The weekend looks great, likely bringing daytime highs in the mid- to upper-teens and overnight lows well above 0°C. Notably, there are suggestions that dew point values will finally climb above 0°C, significantly helping melt any remaining snow. Precipitation continues to look unlikely.

I don’t want to count chickens before they hatch, but it seems likely that over the next week Winnipeg will finally be able to say goodbye to winter and start the spring cleaning!

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