Not in MI!!
here in MI it drops to about 40 by the middle of october, somtimes snow by the end of october, always snow by the end of november and in dec/jan, the wind chill is like -10/-20 an will go through anything. feb is jan with light wind, march we might lose some snow, by april most of the snow is gone, but then we get freezing rain, by mid may it's about 40 agian, and by june it's almost warm enough to go to the field without a winter coat. gotta love MI

Thats ok, I plan to be flying a combat spad during the winter, so I should be alright.
