The animated movie on the weather.gov/medford/wildfire web page is based on the HRRR. Typically those movies only go out 18 hours.

The HRRR smoke model has really improved over the past several years and can provide a good idea on where the greatest/least concentration of smoke will be, out to 48 hours. Please understand when viewing this imagery that no model is perfect, and it's usually best to use to view trends where smoke is getting worse or better. Take a look at the AQI in your area, and then you can use the model to see if it looks like your area will improve or worsen through the day/night.
