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 11 hours are free. Pro members get all seven days and the CSV.

Every hour from the forecast, the same arithmetic as the pit box above (NWS density-altitude formula; track temperature is an estimate). Hours are track time.
Plan the whole week at Interstate
Pit box, all week
Every forecast hour for the next seven days at Interstate: density altitude, air density, grains, track temp and more, with a CSV for the tuning laptop.
Do the models agree?
ECMWF, GFS and ICON side by side for the next three racing days, so you know when the forecast is shaky.
Next 6 hours of rain
Rain in 15-minute steps for the next six hours at your tracks, refreshed every hour.
Alerts for your tracks
An email the morning a red or yellow flag is due at Interstate, and a heads-up three days out.
A year at Interstate
Typical for November here: highs around 40°4°, lows 26°-4°, rain on 19% of days.
5-year averages from the Open-Meteo archive at the track's coordinates.
