The Ottawa Valley is often up to 2 C cooler than the surrounding area. When the temperature is near freezing, an interesting effect is rain can fall but turns to ice as it passes through the colder air in the valley. The result is a freezing rain that leaves a coating of ice on everything. Luckily, this was just a light rain - nothing unusual - and the ice will soon be gone, but in 1998, we had a famous ice storm. There was even a book written about it!
It may look like water on the vines, below, but it's a thin layer of ice.
