Keep bundling up; this cold snap is sticking around for the rest of the week. Environment Canada Meteorologist Geoff Coulson says an air mass from the arctic is causing the frigid temperatures in Muskoka.
Coulson says the district is facing much colder temperatures than the average; which is minus five degrees in January, while the overnight low is usually around minus 15.
Coulson adds this cold spell is affecting all parts of the country east of The Rockies, but as of Sunday we may start to see warmer weather.
Environment Canada is predicting a high of minus seven on Sunday, and minus four on Monday.
