The afternoon 'wind' routes to JFK have 4 connection points to chose from for ZLA departures.  The overnight 'wind' mid-routes only have two connection points for ZLA departures SPI and KK54E.  Those two points are only 53 nm apart.   Due to convective weather in the Western Mississippi Valley; I needed to file [2] flights on a more northerly routing.  FOD [Fort Dodge Regional] is the most northerly routing from the afternoon wind routes but is not offered on the overnight wind routings.  ATC re-routed back on the published mid-routes which brings my flight right through the convective weather. ATC does not take into account enroute weather when publishing mandatory re-routes.  ATC needs to take into account enroute weather off more choices for the overnight mid-routes to both JFK and EWR.
Air carrier Dispatcher reported the ATC issued 'wind routes' required for filing a JFK arrival conflicted with weather the Dispatcher was trying to avoid.
