Plot Description:

The map presents IEM computed climate district or statewide values for a metric of your choice. This map can be generated for a given month and year or period of dates. If the period of days includes leap day, this day is included and unweighted against years without it. If the period spans two years, the presented year on the map represents the second year in the selection. For plotting period Option 2, the time period is limited to 1 year or less.

The data uses the current NWS COOP nomenclature of reporting each day at approximately 7 AM. So for example, a plot of June precipitation would stricly include the period of 7 AM 31 May to 7 AM 30 June. Data for the current date is available at approximately noon central time each day.

Aridity Note: Presently, this autoplot can only plot the value and not departures nor ranks. Hopefully, this can be implemented in the near future.
