Northern Ontario Weather Trivia!

Did you know that on March 13, 1996, Fort Severn recorded a staggering -37.4°C? That same year, Pikangikum saw one of its biggest March snowstorms, dumping over 30 cm of snow! This year, we’re seeing a mix of everything, from freezing rain to blizzards, proving once again that March in the North is anything but predictable!
