Residents of southern Manitoba should buckle up for a meteorological ride, according to the latest forecast from meteorologist Colleen Bready. A significant temperature rollercoaster is on the horizon, promising a week of dramatic swings that will challenge wardrobes and heating bills alike.
Forecast Details and Expected Swings
In her forecast published on January 12, 2026, Colleen Bready outlined the incoming weather pattern set to dominate the region. The period is expected to feature sharp fluctuations between unseasonably mild conditions and plunging, bitter cold. This pattern is characteristic of a volatile jet stream pulling air masses from vastly different source regions across the Prairies.
While specific high and low temperatures for the coming days were detailed in her report, the key takeaway is the rapid changeability. One day might feel almost spring-like, only to be followed by a stark return to deep winter conditions within a 24 to 48-hour window. Such swings can impact everything from road conditions due to freeze-thaw cycles to personal health and energy consumption.
Preparing for Weather Whiplash
This type of weather pattern, often colloquially called "weather whiplash," requires proactive preparation from the public. Colleen Bready typically advises residents to stay updated on the daily forecast rather than relying on a single day's conditions. Layered clothing becomes essential, as temperatures can shift dramatically from morning to evening.
Infrastructure is also tested during these cycles. Rapid freezing can lead to black ice on roads and walkways, while thawing can create pooling water and slush. Homeowners are often cautioned to monitor their properties for potential ice dam formation on roofs during the warming periods, which can lead to leaks when temperatures drop again.
Regional Context and Broader Patterns
The forecast for southern Manitoba's temperature volatility comes amidst a week of significant weather and news events across Canada. From wind warnings with gusts forecast up to 120 km/h in other provinces to evacuation orders due to heavy rain on Vancouver Island, the national weather picture remains active and diverse.
For Winnipeg and the surrounding areas in southern Manitoba, the focus remains on the thermometer. Such rollercoaster patterns are not unheard of in a Prairie winter, but they serve as a potent reminder of the region's dynamic and sometimes unforgiving climate. Staying informed through trusted forecasters like Colleen Bready is the best defense against being caught off guard by the next sharp turn in the temperature track.
