According to weather.com:
The chance of seeing snow on Christmas here in Redmond is... 0%.
The record low temperature on Christmas here is... 25° F.
In contrast, in Lincoln:
The chance of seeing snow on Christmas in Lincoln is... 30%. (I figured higher.)
The average low temperature on Christmas is... 15°. (Ten degrees below Redmond's record.)
I generally like the cold, but 30-40° is plenty cool. No need to overdo it.
