So Cold (NotSo) Accuweather Runs Out Of Colors

NotSoAccuWeather

It’s currently in the below teens in much of the upper plains but you wouldn’t know it according to this (Not So) AccuWeather map  found at USAToday.com. You see Accuweather for some reason only has one color for anything below zero. Even if it was 20 or 30 below zero it would still be just dark blue. And yet they don’t even use the upper 2 shades of red, why is this? Are they trying to hide how cold it actually is?
