I don't think a single year would work very well as the yearly values vary too greatly and it would be very likely one year would be higher. We could set the starting point at 54.2F for 2001 and if the data for 2002-2012 produce a best fit line with a tempreture greater than 54.5F in 2012, you win.
I'll consider over the weekend. What about the spring thaw criterion?
