NOAA Forecast Model Guidance Temporarily Unavailable

On July 20th, NOAA introduced an additional day of availabilty (from 48 to 72 hours) to the CMAQ air quality model. Unfortunately this update will require changes to the AirNow scripts which process and provide this output as model guidance for forecasters. Forecast guidance will be unavailable until these updates are made. We apologize for the inconvenience.
