Mild Late-Summer Weather Continues

Brad Leave a comment

Seasonably mild conditions will continue in Winnipeg this week, but with breezy winds to go with it.

After a blast of summer heat yesterday, Winnipeg will see a much cooler day today in the wake of a cold front that pushed through the province overnight. The showers associated with that system should come to an end early this morning, leaving behind cloudy skies to start the day. Northwest winds will strengthen this morning to 30 gusting 50 km/h and the cloud should begin to clear out this afternoon. Temperatures will reach a near-seasonal high in the upper teens today, more than 10 °C cooler than yesterday’s warmth. All this adds up to rather unremarkable weather as Winnipeggers head to the polls today.

A ridge of high pressure will move into the province overnight, bringing clearing skies and a low near 6 °C. The northwest winds will gradually ease through the night.

Breezy northwest winds will spread across most of southern Manitoba for Election Day (Monday).

On Tuesday, Winnipeg will see mainly sunny skies with a high again in the upper teens. The high pressure system over the province should keep the winds light through the day as well. The light winds will shift southerly overnight as temperatures dip to a low near 8 °C.

The city will see more sunshine on Wednesday, but the southerly winds will pick up through the day as warmer air moves back into the region. The day’s high should reach the mid-20s with southerly winds of 30–40 km/h. A few clouds will start building into the region overnight as the next disturbance crossing the Prairies approaches. The breezy conditions will help keep temperatures warmer on Wednesday night with lows near 12 °C.

Long Range Outlook

Mild weather will stick around for Thursday, but then a strong cold front will slump through the region on Friday. Temperatures will fall into the low teens with plenty of cloud and a good chance of showers. The weekend will bring a return of warmer weather.

Today’s seasonal daytime high in Winnipeg is 17 °C while the seasonal overnight low is 5 °C.

Summer Warmth Returns for the Weekend

Temperatures will soar back into the upper 20s this weekend as southerly winds usher summer weather back into the region.

Before it warms up, Winnipeg will have a day of seasonal temperatures in the wake of yesterday’s rain system. Temperatures will climb to a high near 17 °C with partly cloudy skies from an upper low crossing the province. Breezy westerly winds this morning will ease in the afternoon as a ridge of high pressure builds in from the west. That ridge will scoot across the province quickly, already exiting into NW Ontario by this evening. Another low pressure system moving into the Prairies will push more cloud into the region tonight with strengthening southerly winds. Temperatures will dip to a low near 7 °C.

Moderate southerly winds will push a warmer air mass into the southern Prairies on Saturday. Here in the Red River Valley, southerly winds will strengthen in the morning up to 40 gusting 60 km/h. Any lingering cloud should clear out relatively quickly with a few clouds through the rest of the day. Highs will reach the mid-20s throughout the Red River Valley. More cloud will push across the region on Saturday night as a warm front moves across the Red River Valley. The southerly wind will ease through the night into the 20–30 km/h range and help keep temperatures mild with a low near 18 °C in Winnipeg.

Very warm temperatures will move into southern Manitoba on Sunday.

Skies will clear out again on Sunday with winds shifting westerly for the afternoon as a trough moves across the region. Temperatures will climb even higher on Sunday with highs possibly reaching up to 30 °C. A weak cold front will push through on Sunday evening, bringing a bit more cloud and cooler lows near 14 °C.

Long Range Outlook

The weather next week looks fairly benign with near-seasonal temperatures, variable cloudiness, and little chance of precipitation. Little to complain about for late September conditions!

Today’s seasonal daytime high in Winnipeg is 17 °C while the seasonal overnight low is 5 °C.

Unsettled Conditions Usher In Seasonal Temperatures

A potent low pressure system crossing the northern Prairies will bring unsettled conditions to the region as temperatures cool to seasonal values.

Winnipeg will see another day of seasonally mild temperatures as blustery southerly winds send highs into the low 20s. The winds will pick up to 30 km/h by lunch, then strengthen to 40 gusting 60 km/h through the afternoon. As this push of warmer air moves in, so will the cloud cover. A trough of low pressure will push into the region this evening and will bring a slight chance of an isolated shower or thunderstorm.

The wind will ease overnight as it shifts to the west. Skies will clear and temperatures will dip to a low near 12 °C.

Moderate to strong southerly winds will develop over the Red RIver Valley on Wednesday afternoon.

A disturbance aloft will follow into the region on Thursday, again bringing cloudy conditions to Winnipeg. There will be a chance of showers with this system and temperatures will be cooler with a high near 18 °C. Skies will begin to clear through the afternoon across the Red River Valley as the system pushes off to the east. The stars will be out on Thursday night with temperatures dipping into the upper single digits.

The sun will make its return on Friday with partly cloudy skies and a westerly wind of 20–30 km/h. The city will see a seasonal high near 17 °C. Temperatures will dip to around 9 °C on Friday night with some cloudiness ahead of the next system moving into the region.

Long Range Outlook

Another low will cross the Prairies this weekend bringing variable cloudiness to the region and highs climbing back into mid-20s. Unsettled conditions will likely return into the first half of next week.

Today’s seasonal daytime high in Winnipeg is 18 °C while the seasonal overnight low is 6 °C.

Seasonably Mild Conditions Continue

Winnipeg will see mixed conditions over the next few days, but temperatures will stay warm for this time of year.

It will be a nice start to the day in Winnipeg with partly cloudy skies and a bit of a south breeze as temperatures warm into the low 20s. By midday, more cloud will begin working into the region as a weak cold front pushes towards the region. Much of the region will see a chance of showers through the afternoon as the cold front pushes through. Skies will then clear out overnight with temperatures dipping to a low near 9 °C.

A few showers will push across southern Manitoba later today.

Tuesday will bring plenty of sun to the city with temperatures climbing back to a high near 21 °C. Winnipeg and area will see a moderate northwest wind pick up to around 30 gusting 50 km/h. Skies will stay mainly clear through the day and the night thanks to a ridge of high pressure moving into the region. Temperatures will dip to a low near 9 °C on Tuesday night.

Another low pressure system will track across the Prairies on Wednesday. As it moves towards Manitoba on Wednesday, winds in the Red River Valley will strengthen to into the 30–40 km/h range with gusts up to 60 km/h. Skies will cloud over through the day as a warm front pushes through and temperatures climb to a high near 23 °C. There’s a slight chance that Winnipeg will see a few showers late in the day as a cold front pushes into the region, but it looks quite uncertain right now. The cloud cover will break up behind the cold front overnight with a low near 10 °C.

Long Range Outlook

Temperatures will cool to near-seasonal values for the rest of the week with variable cloudiness. It looks like the next chance for showers will be on Friday night with the potential for some elevated convection developing in the Dakotas and lifting northwards. The weekend will see highs in the low 20s with the potential for a few showers again on Saturday night.

Today’s seasonal daytime high in Winnipeg is 18 °C while the seasonal overnight low is 6 °C.
