Absolutely. What happened to all the below-0 degrees of cold? -2°C is mushy, -10° is crispy, and then it gets very cold. It's important!
EDIT: now I see the last interval is just very large: -9°C to 0°C. Something around -5°C would work better, as this is roughly where the physical properties of the world change, because road salt stops working.
