When Does Houston First See Freezing Temperature?

It is winter and it is about to get cold. So, when does Houston on average first see its first freezing temperature? This is based on data from Intercontinental Airport from 1969 to 2010.

Mean = 335.8 December 1st
Median = 336 December 2nd
Standard Deviation = 18 Days
Earliest = October 15, 1989
Latest = January 5, 1986

If we see our first freeze on Tuesday night or December 6th, it would be within the average.
