A day and night of freezing rain coated trees, homes and roads with 40-45mm of ice. The storm was a product of an Oklahoma low with a potent surface warm front that simply stalled out and could not overcome the dominant sub-freezing easterly flow just north of the great lakes. This created a perfect storm so to speak where the heaviest rain sat right on an axis of rotation and pummelled some areas just north of Toronto for excess of 24 hours. The result was significant ice accretion leading to substantial tree and infrastructure damage.
