Race-morning weather history
Early-December Memphis swings widely; the 2013 race was cancelled for an ice storm — freezing rain is the tail risk. Wyndo tracks what this calendar slot has actually served up at the start hour — temperature, dew point, wind, and rain — including the years when weather canceled or disrupted the race, and reads the live forecast for the start once race week arrives.
