The light coating of snow that fell tonight along with below-freezing temperatures are the recipe for dangerous travel conditions as anything that may have melted today will re-freeze.
Use caution and keep a safe distance between yourself and other cars while driving.
It’s not over yet. More snow is expected on Tuesday then rain at the end of the week.
All of this will add to the weight of the snow already sitting on your roof. If you can, remove the snow, or hire someone to do it before any damage is done.
