Narrative:

Dispatched aircraft with WX forecast from sep/xx/97. This occurred due to company switching from one WX vendor to another. It was caused by a computer error. Neither myself nor the crew of any flight I dispatched discovered the error. I discovered the error on the following day (sep/xy/97).
