Bitter Cold Eases Across Southern Manitoba

Brad Leave a comment

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.

RDPS 2m Temperature Forecast valid 21Z Saturday December 14, 2024
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.

Sunshine Reappears in Winnipeg…Briefly

The sun will finally make a reappearance in Winnipeg today as colder weather moves into the region.

RDPS 2m Temperature Forecast valid 12Z Saturday November 30, 2024
Winnipeg will see chilly overnight lows near -20 °C in the days ahead, but it will be much colder to the west.

Morning cloud cover will give way to sunshine today as the never-ending blanket of stratus cloud finally moves out of the region. The minor cost to finally kicking some of the gloom that’s set in is that temperatures will drop across the region. In Winnipeg, temperatures will hover just below -10 °C today with norhtwest winds steady around 30 km/h.

The winds will ease to around 20 km/h tonight with temperatures dropping close to -20 °C. A bit of lake-effect cloud and snow is possible off of the Manitoba Lakes, so Winnipeg could find itself with mixed skies through the night and perhaps some scattered flurries. Between the wind and the vicinity cloud, it’s unlikely that temperatures will drop much below -20 °C, if at all.

Much colder temperatures will sit just to the west of the Red River Valley; overnight lows in the -25 to -35 °C range will straddle the Saskatchewan/Manitoba border over the next couple nights.

The next couple days in Winnipeg will likely look much the same; cloud drifting into the region from the northwest as it pours off Lake Manitoba in the freeze-up process, possibly with some light snow. Highs will range from just below -10 °C under clearer skies to just over -10 °C under cloudier skies. Overnight lows could be in the -10 to -15 °C range if the band of lake cloud parks itself over the city at night, while it could drop closer to -20 °C if it clears.

Conditions may trend sunnier on Sunday as winds shift more northerly which would shift lake-effect cloud bands out of the Winnipeg area.

Long Range Outlook

Looking ahead, a low pressure system is likely to move through the region Monday night through Tuesday. Dropping down from the northwest, it looks to bring 5 to 10 cm of snow to central Manitoba with amounts diminishing southwards. It will come with a push of colder air, so there is still uncertainty with its track. This system will likely produce a swath of 5 to 15 cm of snow, but whether that occurs through central Manitoba or along a strip from the Parkland through the Red River Valley is unclear at the moment.

Behind this system, a push of colder air will move into southern Manitoba and send temperatures colder through the second half of the week.

Today’s seasonal daytime high in Winnipeg is -6 °C while the seasonal overnight low is -15 °C.

Cooler, Cloudy Weather Ahead for Winnipeg

The Winnipeg area will stay smothered in cloud cover this week as temperatures gradually cool.

RDPS 2m Temperature Forecast valid 21Z Thursday November 28, 2024
While temperatures will drop in southern Manitoba this week, the region will avoid the bitter cold that will move through the western Prairies.

The Winnipeg area will be stuck under a blanket of cloud cover this week thanks to a stagnant flow over the region. Winds will stay light over the next few days as a weak ridge of high pressure stalls over southern Manitoba.

While an occasional sunny break may be possible, it looks like skies will stay mostly cloudy to overcast for the next several days.

Daytime highs will hover around -6 °C over the next couple days with overnight lows close to -10 °C. With temperatures in this range, flurries will be possible over the next couple days as well.

A cold front will slide through the area on Thursday, bringing breezy northwest winds and cooler temperatures. Winds should climb up to 30 gusting 50 km/h on Thursday as colder air pushes in. Temperatures will struggle to break -10 °C and then head down into the mid-minus teens on Thursday night. The cooler temperatures will make flurries less likely, but with the push of colder air there will be a chance that some lake-effect snow streams off Lake Winnipeg and Lake Manitoba.

Long Range Outlook

Heading into the end of the week, skies will likely stay mixed to mostly cloudy right through the weekend. Some sunshine is possible, but will more likely be through breaks in the cloud and any widespread clearing.

Temperatures will hold relatively steady with highs in the -15 to -10 °C range and overnight lows in the -20 to -15 °C range. Now that the city has snow on the ground, it will be much easier for temperatures to drop overnight, especially under any clearing that could develop.

Winds will gradually ease and there could still be some more flurries, but with the likelihood dropping along with the temperature.

Today’s seasonal daytime high in Winnipeg is -5 °C while the seasonal overnight low is -13 °C.

November Warmth Continues This Week

Brad Leave a comment

Southern Manitoba will recover from the weekend rain quite nicely with warming temperatures and lots of sunshine.

RDPS 2m Temperature Forecast valid 21Z Thursday November 7, 2024
An upper ridge will begin to push mild weather into Manitoba later this week.

A ridge of high pressure will bring plenty of sunshine to the Winnipeg region today with light winds. Temperatures will climb to a seasonably mild high around 6 °C this afternoon. Tonight, a decaying low pressure system will begin to spread cloud cover into the region as temperatures head to a low down to around -3 °C.

Tomorrow, Winnipeg and the Red River Valley will see mainly cloudy skies as the decaying system mentioned above moves through. The clouds will keep it cooler with a near-seasonal high in the low single digits and winds will continue to be light. Skies will gradually clear out tomorrow night with a low down near -5 °C.

For the rest of the week, an upper ridge will build into the Prairies, bringing sunshine and warm weather. Daytime highs will climb into the 5 to 10 °C range with lows near freezing or warmer for the second half of the week. Winds will become more present on Thursday with southerly winds strengthening into to 30–40 km/h range for the afternoon. Winds will become calmer again on Friday.

Long Range Outlook

Pleasant conditions will last right through the weekend with seasonably warm daytime highs and mainly sunny skies. The pleasant conditions will continue into the start of next week week, but temperatures will begin to moderate towards more seasonal values.

The next chance for precipitation looks to come in the middle of next week, and it could come as a mix of rain and snow. It doesn’t look like accumulations will be all that much, but we could see the first coating of snow of the season. Temperatures will continue to be mild, though, so it’s unlikely that the snow will stick!

Today’s seasonal daytime high in Winnipeg is +2 °C while the seasonal overnight low is -7 °C.
