While preplanning the release for Flight ABC ZZZ-ZZZ1 arrival time XA45Z; [Flight Planning Software] advised the Dispatcher with the following message:  NO ALTERNATE RECOMMENDED - ZZZ2 INPUT THRESHOLD-ALT...DONE ON DESTINATION STATION ONLY PER [FLIGHT PLANNING SOFTWARE] RULES The weather/forecast for ZZZ1 was as follows: A) 22005KT P6SM OVC035 TEMPO 2716/2721 -RA OVC035 B) 30005KT P6SM -RA OVC035 TEMPO 2721/2800 4SM -RA BRC) OVC 025   D) 14006KT 5SM -RA OVC025 TEMPO 2800/2806 3SM -RA BRE) OVC015     F) 14006KT 5SM BR OVC025 TEMPO 2806/2810 3SM -RA BRG) OVC015                        Note lines D and E above in the weather forecast; [Flight Planning Software] is advising the Dispatcher to violate FAR 121.619. Because of Dispatcher interaction; ZZZ2 was added as alternate for ZZZ1 thus ignoring the [Flight Planning Software] automated message advising to violate FAR 121.619. There is an obvious fallacy in the [Flight Planning Software] program or the team who developed the program does not understand what is required to determine alternate weather minimums per FAR 121.619. Eliminate [Flight Planning Software] until this product can provide a useful purpose to the Dispatcher; otherwise it will continue to mass produce unnecessary messages that will be ignored since it is advising inaccurate and false direction for the Dispatcher to implement.
A Dispatcher does not agree with the automated weather software assessment that an alternate airport is not required for the conditions; and expresses his concern about the validity of the flight planning software.
