Every hour from the forecast, the same arithmetic as the pit box above (NWS density-altitude formula; track temperature is an estimate). Hours in your time zone, the track’s when they match.
Raceway Weather Pro
Plan the whole week at High Plains
Pit box, all week
Every forecast hour for the next seven days at High Plains: 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 High Plains, and a heads-up three days out.
