Here’s a collection of all the graphics I have shared on social media and on TV today.
Temperatures and precipitation, showing timing of transition from rain to freezing rain and sleet to snow:
What’s the difference between sleet and freezing rain? Freezing rain occurs when there is a deep enough warm layer aloft, allowing the precipitation to remain liquid until it hits the ground, where it freezes on contact. Sleet occurs when the warm layer is shallower, meaning there is time for the rain to refreeze into ice pellets. Freezing rain is much more problematic.
Wind chills will be rather harsh during the weekend.
