About This Product
The Maximum/Minimum Air Temperature Difference map plots two values for each Mesonet station:
- the difference between yesterday's maximum temperature and the previous day's maximum temperature
- the difference between yesterday's minimum temperature and the previous day's minimum temperature.
Both values are plotted in degrees F. This map is updated once daily.
