Hour by hour
Hours are track time (EST). Track temperature is an estimate. DA is density altitude.
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
Every hour, every number
Today’s remaining 10 hours are free. Pro members get all seven days and the CSV.
