I recommend a good pair of hankook all weathers instead of playing the winter tire summer tire game. Just use chains if the roads are going to be that bad

I've dealt with ice on the windshield at home in the morning. Only once I was leaving work at night, and the windshield was frozen over with no hose anywhere near. I was drinking a bottle of water. I started pouring that on the windshield. I guess I got enough ice removed to drive home.
