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 is generated. Like our daily weather forecasts, the closer to the start of the time period an outlook is issued, in general, the higher the accuracy will be. For example, an April outlook generated 10 days prior to the start of April (i.e., generated around 20 March) will have higher accuracy than the April outlook generated 20-days prior to the start (i.e., generated around 10 March). View accuracy information by selecting options from the lists below. 20 and 50 days earlier refers to the outlooks issued mid-month, 10 and 40 days earlier refer to outlooks issued at the end of the month.
