The racer numbers
Computed from the forecast air temperature, dew point and station pressure (NWS formulas; the correction factor by SAE J1349 and the older 60 °F STD standard). Track temperature is estimated from sun, wind and the surface; it is not a sensor reading. How these are figured.

Flags judge the racing hours: 9 am to 10 pm at the track for a drag strip. National Weather Service alerts raise them. Days marked partial are at the edge of the forecast. How the flags work
