Plot Description:

This application produces map analysis of climatological averages. The IEM maintains a number of different climatologies based on period of record and source. If you pick the NCEI Climatology, only basic temperature and precipitation variables are available at this time.

If you select a period of dates with the end date prior to the start date, the logic then has the period cross the 1 January boundary. For example, a period between Dec 15 and Jan 15 will be computed.
