Urgent Weather Alert: Rain Turns to Snow as December Approaches

URGENT UPDATE: A significant weather shift is underway as rain transitions to snow across southern Ontario, just in time for December. Meteorologist Julie Atchison from CTV News London warns that showers are expected to intensify this afternoon, with a 40 percent chance of precipitation early today and increasing likelihood as temperatures begin to plummet.

Authorities confirm that cold air will sweep into the region starting Wednesday night, bringing a major change in weather conditions. “We will start to usher in December with colder temperatures and the risk for flurries,” Atchison noted. The forecast indicates potential for snow squalls, particularly in Grey and Bruce County through the week.

Residents should prepare for what may become a multi-day snow squall event for London, with the heaviest snowfall expected in midwestern Ontario. “As temperatures drop, it will get windy. If the weather system aligns perfectly over Lake Huron, we could see significant snow squalls,” Atchison added. The urgency of this forecast cannot be overstated, as this drastic change may impact travel and daily activities.
