Hour by hour
Hours in your time zone (the track's when they match). Track temperature is an estimate.
The racer numbers
Computed from the forecast air temperature, dew point and station pressure (NWS formulas). Track temperature is estimated from sun, wind and the surface; it is not a sensor reading. How these are figured.
