Plot Description:

This chart displays the combination of Model Output Statistics (MOS) forecasts and actual observations by the automated station the MOS forecast is for.

The case of ~Daily Max/Min Air Temperature is difficult to explain. The NBS/NBE values are slightly different periods than the GFS/NAM values. Some care is taken to attempt to properly align the MOS values to the observations and consider METAR 6-hour max/min temperatures when appropriate.

The bars represent the ensemble of previously made forecasts valid for the given time.

The IEM MOS Mainpage has more details and services for this dataset.
