Plot Description:
Based on available hourly or better observations, the IEM computes local calendar day statistics for variables like relative humidity, dew point, and feels like (read: windchill or heat index) temperature. This autoplot computes a simple climatology of these values with a smoothing to remove some of the day to day variability.Note that the observations plotted can fall outside of the smoothed range of values, as the smoothing is applied to the climatology and not the individual observations.
