Plot Description:

The IEM computes a daily maximum and minimum relative humidity value based on whatever observations were available for that calendar day. This app presents these values along with a simple climatology computed by averaging the daily observations. You can also plot a frequency of the RH value being above or below some threshold. This frequency is grouped by week of the year to provide some smoothing to the metric.

Based on a sampling of recent timings for this application, plot generation time has averaged 10 seconds. Hold on for the plot is generating now!
