Outlook past accuracy maps

The accuracy of a particular monthly, or seasonal, outlook will vary, depending on how long before the start of the month or season it was generated. Generally, the closer to the start of the time period an outlook is produced, the higher the accuracy will be. For example, an April outlook generated 10 days prior to the start of April (i.e., generated around March 20) will have higher accuracy than the April outlook generated 40-days prior to the start (i.e., generated around February 18).
