Wind on the strip—The strip’s direction is not mapped
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.

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.
Raceway Weather Pro
Plan the whole week at Tri-State
Pit box, all week
Every forecast hour for the next seven days at Tri-State: 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 Tri-State, and a heads-up three days out.
Typical for November here: highs around 47°8°, lows 31°-1°, rain on 21% of days.
Month by month
Average highs and lows, rain days, gusty days, freezing and hot days for all twelve months at Tri-State, from 5 years of records. Part of Raceway Weather Pro.
