The bitterly cold air that slammed into southern Manitoba earlier this week is on its way out, and after an unpleasant Friday, nicer winter conditions will develop for the weekend.
Breezy southerly winds will eventually bring warmer temperatures to southern Manitoba.
Although warmer weather will begin working its way into the Red River Valley today, it will be a rather miserable day outside. As an Arctic high slowly works its way east, its return flow of cold air will strengthen over the region. Southerly winds will strengthen into the 30 to 40 km/h range as temperatures climb towards a high in the mid-teens, but those winds will keep wind chill values in the -35 to -25 range through the day.
The southerly winds will continue into the night and temperatures will warm slightly overnight as skies cloud over.
Heading through the weekend, a low pressure system tracking across the southern Arctic will spread milder air east through the Prairies. With skies on the cloudier side through both Saturday and Sunday, temperatures will rise into the -10 to -5 °C range on Saturday and closer to the freezing mark on Sunday. It will be a bit of a breezy weekend, though, with southerly winds of 20 to 30 km/h on both days. Overnight lows will climb into the -10 to -5 °C range for the weekend.
Long Range Outlook
More snow is possible overnight Sunday into Monday as a low pressure system develops and moves through the Dakotas. Early indications are that 2 to 5 cm of snow are possible before this system moves out of the region on Tuesday. Colder weather will build in behind it with temperatures dipping back to seasonably cool conditions.
Today’s seasonal daytime high in Winnipeg is -10 °C while the seasonal overnight low is -19 °C.
Winnipeg will see its first shot of bitterly cold Arctic air as a ridge of high pressure builds into the region this week.
An Arctic high will bring bitterly cold temperatures with lows in some places falling below -30 °C this week.
With the system that brought 15 to 20 cm of new snow to Winnipeg on its way out, the next system to shape the weather in the region will be an Arctic High building into the province from the north.
Before it gets here, though, a weak disturbance will move through the region today. It will bring a little bit of light snow, perhaps another 2–4 centimetres, today and then sweep a strong cold front southwards.
Temperatures will plummet behind the front as northerly winds of 30–40 km/h drive Arctic air southwards. A seasonable high near -10 °C today will quickly be forgotten as skies clear tonight and temperatures head to a low in the mid-minus 20s.
The Arctic High will be in full force through the rest of the work week. With plenty of sunshine, daytime highs will struggle to climb into the -25 to -20 °C range with overnight lows dipping back into the -25 to -35 °C range. Wind chill values will likely get close to -40 at times on Wednesday night and Thursday night.
Long Range Outlook
Temperatures will begin to moderate on Friday as the high begins to weaken and the core of coldest air moves out of the region. Daytime highs should climb back above -20 °C but breezy southerly winds will have a bite to them and produce wind chills that make it feel much worse.
Temperatures will climb back to seasonal values for Saturday and continue warming on Sunday. The region will likely see mixed skies through the weekend.
A bit of snow is possible later Sunday into Monday ahead of colder temperatures slumping back into the region.
Today’s seasonal daytime high in Winnipeg is -9 °C while the seasonal overnight low is -18 °C.
A low pressure system moving through southern Manitoba will bring snow and mild temperatures to the Red River Valley. In its wake, colder temperatures and strong winds will surge into the region.
Strong winds will develop across the Red River Valley late Tuesday into Wednesday, likely producing widespread blowing snow across the region.
Apologies for the late forecast, life has been busy!
Snow spread across much of southern Manitoba this morning as a low pressure system pushed a warm front into the region. A burst of moderate to heavy snow has moved through the region this morning, and now milder temperatures will spread across the region with daytime highs of -5 to 0 °C across southern Manitoba. As the warm air moves in, stiff southerly winds will shift to lighter westerlies.
A cold front will sweep through later today, ushering in some light snow and a major shift in the weather. Temperatures will plummet into the minus teens tonight as northwesterly winds strengthen into the 40 to 50 km/h range with gusts of 60 to 80 km/h. It’s likely that lake-effect snow will develop off the lee of Lake Manitoba and Lake Winnipeg, producing a band of flurries that could last well into Wednesday.
The colder temperatures, new snow, and strong winds will likely produce widespread blowing snow across the region, though limited snowpack inside of Winnipeg could reduce the overall amount of blowing snow within city limits. Of particular concern will be the Trans-Canada Highway corridor between Winnipeg and Portage la Prairie where strong winds, existing snow, and lake-effect snow could combine to produce white out conditions and potential highway closures heading through Wednesday.
With those strong northwest winds, temperatures will only recover a couple degrees on Wednesday before dropping down to a low in the -20 to -25 °C range on Wednesday night. Wind chilled values will likely hover in the -25 to -30 range all day then closer to -30 overnight as the wind dies off.
A ridge of high pressure over the province on Thursday should bring partly cloudy skies to the region, light winds, and highs in the mid-minus teens.
Long Range Outlook
Another notable pattern shift will occur late this week as a strong low pressure system is forecast to track across the southern Arctic. This system will send warmer air sweeping across the Prairies, sending daytime highs back towards the 0 °C mark on the Weekend. More snow looks possible eon Sunday as a cold front pushes through the region, then it looks like a return to near-seasonal conditions for much of next week.
Today’s seasonal daytime high in Winnipeg is -7 °C while the seasonal overnight low is -16 °C.
The mild fall conditions seen across southern Manitoba will continue into mid-November. There will be weather, though: after a blustery Tuesday, Winnipeg will see several chances for rain over the next week.
Strong southerly winds will develop over the Red River Valley today.
Temperatures will stay well above seasonal values in Winnipeg this week as mild air continues to flood into the southern Prairies. While winter weather isn’t that far away — the farther reaches of northern Manitoba and southern Nunavut have seen temperatures near -20 °C or colder already this year — that cold air won’t be making its way south any time soon.
Rather, winds will stay more southerly and westerly over the coming week, bringing daytime highs 5 to 10 °C above seasonal values and keeping overnight lows equally mild.
Starting off with today, it will be a seasonably mild day but marked most notably by strong southerly winds. with the region squeezed between a high pressure system to the southeast and a low pressure system in northern Saskatchewan, southerly winds will strengthen into the 40 to 50 km/h range today with gusts as high as 70 km/h through the Red River Valley. Temperatures will climb to a high near 7 °C this afternoon as skies cloud over.
Cloudy skies will continue through the night as southerly winds gradually taper off into the 20 to 30 km/h range. The cloud and wind will keep things mild with lows dipping just below 5 °C.
On Wednesday, temperatures will rebound back into the upper single digits as a trough of low pressure moves through the region. That trough will bring a chance of some light midday rain showers that clear out of the region for the afternoon. Some sunny breaks are possible as skies likely clear out heading towards the evening. Those southerly winds will also ease in the morning, then switch to light northwesterlies behind the trough.
Temperatures will head to a low near freezing on Wednesday night with light winds and clear skies. Some fog patches could develop overnight and last into Thursday morning.
On Thursday, more cloud will develop over southern Manitoba as another low pushes into Saskatchewan. Temperatures will again climb into the upper single digits as winds shift back out of the south and strengthen into the 20 to 30 km/h range. The low in Saskatchewan will lift northeast through the day, lifting its warm front with it and bringing the Red River Valley into its warm sector. This should bring clearing skies on Thursday night with a low in 0 to 5 °C range and southerly winds of 15 to 20 km/h.
Long Range Outlook
On Friday, Winnipeg should see a beautiful mid-November day in the warm sector of the low tracking through the province. Daytime highs could be as high as +10 °C with sunny skies and a southerly breeze.
The warm weather will persist into the weekend, but another low moving into the area will bring cloudier skies with a good chance of rain on Saturday. Conditions will settle on Sunday with mild weather lasting right into Tuesday.
Tuesday/Wednesday next week will likely bring more rain to the region with temperatures likely beginning to cool off behind it. That said, there’s quite a bit of discrepancy in the guidance at this point; some keep it relatively mild, while others bring a sharp cold snap into the region.
Either way, there’s at least another week of pleasant, mild November weather ahead. Hope you can enjoy it!
Today’s seasonal daytime high in Winnipeg is -1 °C while the seasonal overnight low is -8 °C.
