You just don’t get it do you? If my forecast for Sunday is for 0.05” of precip do I really give a shit how cold it is? I’m not an idiot. Of course I need BOTH. I’ll say it again, no precip =no chance. Precip = a non zero chance typically during winter. Places that get precip are guaranteed snow this weekend as temps are iffy, but they have a chance. Would you rather have that or a completely zero chance?
