Residents of London, Ontario, can finally breathe a sigh of relief as the grip of an intense Arctic air mass begins to loosen. The region is set for a significant shift in weather patterns, moving away from the bitter cold towards conditions much closer to seasonal norms.
Forecaster Predicts a Major Thaw
According to the latest forecast from CTV News London meteorologist Julie Atchison, the prolonged period of frigid temperatures is coming to an end. The change is expected to bring a noticeable moderation in the air, with thermometers climbing to readings that are typical for mid-December in southwestern Ontario.
The shift is not just about warmer air. Atchison indicates that rain is on the way, replacing the dry, biting cold that has characterized the recent weather. This precipitation will further contribute to the melting of any accumulated snow and ice, signaling a definitive break from the deep freeze.
From Extreme Cold to Seasonal Norms
The forecasted transition marks a stark contrast to the conditions experienced over the past week. The Arctic chill had plunged temperatures well below freezing, creating hazardous conditions and prompting numerous cold-weather advisories. The move to near-normal temperatures will be a welcome change for commuters, pedestrians, and anyone spending time outdoors.
This weather update, provided on December 16, 2025, offers a clear outlook for the coming days. While winter is far from over, the immediate future points towards a more manageable and seasonally appropriate climate for the Forest City.
What This Means for Londoners
The easing of the cold snap brings several practical implications:
- Safer travel conditions as ice melts and road treatments become more effective.
- A reduction in the risk of frostbite and cold-related health emergencies.
- The potential for temporary fog or mist as the warmer, moist air moves over colder ground.
While the rain may create its own set of challenges, such as wet sidewalks and possible pooling water, it is generally seen as a preferable alternative to the dangerous wind chills and extreme cold warnings that have been in place. Londoners are advised to swap their heaviest parkas for waterproof jackets as the region transitions into this warmer, wetter pattern.
