Is it possible they could occur when the surface temperature is more,
um, temperate, but the temps aloft, at the right altitude, are brutal?
I ask because back around Thanksgiving or Christmas I saw what I would
have sworn were sundogs, but the surface temperature was -8C or -10C,
not -20C.
It's possible, but I don't think it is the norm.
As Herb mentioned, it is the temperature in the stratosphere that makes em happen.
Around here, we don't see them until it is ugly cold out.
