Polar Vortex Brings Frigid January Temperatures to GTA

The Greater Toronto Area (GTA) is currently experiencing a severe cold snap due to a polar vortex. This Arctic air mass has led to significantly low temperatures that are expected to persist throughout January. The current temperature in Toronto is -13°C, but wind chill makes it feel like -24°C. Nearby Vaughan feels like -19°C, while Oshawa is colder at a wind-chill equivalent of -22°C.

Understanding the Polar Vortex

Meteorologist Ross Hull from Global News explained that the polar vortex typically develops around the Arctic Circle. This phenomenon involves outbreaks of frigid air that can migrate southward. Hull indicated that the current Arctic air intrusion is expected to linger for a few more weeks.

Temperature Predictions

• Temperatures in the GTA will remain several degrees below normal.
• A brief warm-up is anticipated mid-week due to an Alberta clipper moving through the region.
• This clipper might raise temperatures closer to zero but will bring some snow, likely around 5 cm.

In the eastern GTA, areas like Scarborough and southern Durham could receive up to 8 cm of snow from this system. However, temperatures are forecasted to drop again starting Thursday, with Toronto expected to hit -4°C and -11°C on Friday and Saturday.

Health and Safety Advisory

As the cold persists, several municipalities, including Toronto, Durham, and Peel Region, have opened warming and emergency shelters for those in need. Although Environment Canada has not declared an extreme cold alert, it is crucial to remain vigilant as health risks associated with cold weather, such as frostbite and windburn, still exist.

• Dress appropriately for the cold.
• Engage in physical activity to maintain body warmth when outdoors.
• Always check weather conditions before venturing outside.

Caution is advised to ensure safety during this harsh winter weather. Residents should prepare for continued cold temperatures and potential weather changes in the upcoming days.
