Winnipeg will see a warm end to the work week give way to slightly cooler, cloudier conditions for the weekend.
Winnipeg will see great summer weather today. A weak ridge of high pressure over the region will keep skies mainly sunny and winds light. The city will see temperatures climb to a high near 25°C with northerly winds near 20 km/h through the afternoon. Cloud cover will move in overnight as a disturbance approaches from the northwest. The city should see a low near 11°C.
Saturday and Sunday will both bring mostly cloudy conditions to Winnipeg with high temperatures near 20°C and lows near 10°C. The rain associated with the disturbance moving through will fall mainly over southwest Manitoba, but a few showers might creep into the Red River Valley. Either way, it looks fairly dry for Winnipeg right through the weekend.
Long Range Outlook
Next week will kick off with seasonal conditions and variable cloudiness in Winnipeg. By mid-week, though, a marked change in the weather pattern is forecast that will bring unsettled conditions to the region. Through the second half of the work week, multiple rounds of showers and/or thunderstorms look possible, perhaps giving some needed rain to parts of the region.
Today’s seasonal daytime high in Winnipeg is 23°C while the seasonal overnight low is 11°C.
Winnipeg will continue to see pleasant weather through the second half of the week. A few showers are possible Thursday afternoon into Friday morning as a weak low pressure system moves through the region.
A ridge of high pressure over the region today will ensure that Winnipeg sees mainly sunny skies through the day. Temperatures will continue at slightly below-seasonal values with a high near 19°C. The lack of wind and ample sunshine should help it still feel rather nice outside, though. Winds will remain light tonight with temperatures dipping to a low near 8°C under clear skies.
Thursday will start off sunny, but a weak warm front moving into the region in the afternoon will bring more cloud and a chance of showers. Winds will pick up out of the south-south-west into the 20 to 30 km/h range, pushing temperatures temperatures to a seasonal high near 23°C. A low pressure system will move through the region overnight, keeping cloudy skies with a chance of showers around through the night. Temperatures should dip to a low near 11°C with light winds.
Friday should start off with a few showers exiting the region, then a bit more sun returning. Temperatures will climb to a high again near 23°C with a northerly wind near 20 km/h. Winnipeg will likely see partly cloudy skies on Friday night with a low near 10°C.
Long Range Outlook
The weekend should bring Winnipeg near-seasonal temperatures and variable cloudiness. Winnipeg won’t likely see any significant chances of rain until sometime early next week. Forecasts show a more unsettled pattern developing over the region, bringing slightly warmer temperatures alongside plenty of cloud and a chance of precipitation.
Today’s seasonal daytime high in Winnipeg is 23°C while the seasonal overnight low is 10°C.
A northwesterly flow aloft will bring seasonably cool temperatures and variable cloudiness to Winnipeg this week.
There won’t be too much of a change in the weather over the next few days as cooler conditions settle in behind the blast furnace the city saw on Friday. Temperatures over the next three days will be consistent with highs near 20°C and lows of 5 to 10°C.
Both today and Wednesday will bring just a few clouds to the city, but Tuesday will bring more cloud as a shortwave moves through. A few showers or perhaps even an isolated thundershower will move into the Red River Valley on Tuesday afternoon, but might stay west and south of the city.
Winds will also be fairly consistent over the next few days. Winds will increase out of the northwest or north into the 20 to 30 km/h range each day and diminish at night.
Long Range Outlook
The rest of the work week will bring more of the same to Winnipeg with highs continuing in the low 20s and variable cloudiness. Temperatures will warm up slightly for the weekend, but no major changes are forecast.
Today’s seasonal daytime high in Winnipeg is 23°C while the seasonal overnight low is 10°C.
Today will be a scorcher over southern Manitoba as strong southerly wind pump hot and increasingly humid air northwards. With that heat, though, will come a fair amount of instability and one of the first widespread severe thunderstorm threats of the season.
To start the day, some elevated convection will move across the region, most likely through the Interlake. These thunderstorms may be strong to severe, but should remain north of the Red River Valley. Although the storms should pass north of Winnipeg, the city will still see some passing cloud as they move by. These storms and their cloud cover should clear out by midday. As the sun comes out, the wind will pick up. A tight pressure gradient over the region1 will produce southerly winds up to 50 gusting 70 km/h today, helping heat and moisture surge northwards out of the United States. With those strong winds in place, Winnipeg will see temperatures climb to a high near 33°C. It will also get a tad more humid as the day goes on as dew points rise into the mid-teens.
Strong southelry winds will be in place over southern Mantioba this afternoon. To the west, a trough of low pressure extending southwards into the United States may trigger a line of thunderstorms late in the day.
By late in the afternoon, the thunderstorm threat will begin to build. A trough of low pressure over southwestern Manitoba into the Interlake may trigger the development of thunderstorms. If they develop, they’ll likely be strong to severe with primary threats of large hail and strong winds. Any of these thunderstorms that develop will move eastwards towards the Red River Valley through the evening. The focus then turns southwards to the Dakotas. A shortwave lifting northeastwards through the state will trigger convection late in the day. These thunderstorms will grow upscale and expand in coverage overnight. As the evening progresses, this blossoming area of thunderstorms will gradually spread across southern Manitoba. The potential for strong to severe thunderstorms exists tonight, with large hail and damaging wind gusts the primary threats. The thunderstorms should be through the Red River Valley by Saturday morning.
Temperatures will remain mild on Friday night with a low near 19°C. Those strong southerly winds will ease into the 20 to 30 km/h range this evening and then diminish to light overnight.
If thunderstorms are able to develop along the trough, southern Manitoba may see a line of thunderstorms marching towards the Red River Valley early in the evening.
Saturday will bring plenty of cloud to Winnipeg as the low pressure system responsible for all this heat and instability moves through. Temperatures will be much cooler with morning temperatures near 18°C dropping to 14°C through the day. Winds will gradually pick up out of west into the 20 to 30 km/h range. More showers with the risk of thunderstorms are likely to develop later in the morning and persist through much of the afternoon. Conditions will calm down on Saturday night with some clear breaks developing towards Sunday morning. Winnipeg should see a low temperature near 9°C.
Sunday will bring seasonably cool conditions to Winnipeg, but things will get a chance to dry out. The city should see a high near 19°C under partly cloudy skies. Westerly winds near 30 km/h will be in place for much of the afternoon before diminishing in the evening. Winnipeg will see a low near 8°C with just a few clouds on Sunday night.
Long Range Outlook
Next week will bring seasonably cool temperatures with daytime highs around 20°C and overnight lows close to 10°C. The city will see variable cloudiness through the week, and a couple of passing disturbances may bring a chance or two of showers through the week. Temperatures should begin to warm up near the end of the week, but that may bring a return to unsettled conditions.
Today’s seasonal daytime high in Winnipeg is 23°C while the seasonal overnight low is 10°C.
The tight pressure gradient is a result of a 996 mb low over western Manitoba squishing against a ridge of high pressure extending through SE Minnesota into Iowa.
