Slushy Michigan rain in December. Slushy December rain. When you live in Michigan, the weather can be pretty unpredictable. It might be sunny, rainy, and snowy all at the same time. It’s actually been pretty cold and snowy over the last couple of weeks, but during a brief warm-up, nearly everything melted, and it even rained for a day before completely snowing over again. This recording of surprise winter rain was captured with the BasicUchos and F3 under an umbrella. These are Outdoor Sounds.
