System that allows naturalistic weather processions. The system starts by generating a weighted chance (based on the time of year) for a weather type (drizzle, rain, storm, snow) to happen within a defined slot (can be set by user), then it checks to see if conditions allow for that weather type to occur (for example a storm cannot happen if it hasn't been raining). Then the system deploys the weather type for the remainder of the slot and the whole cycle starts over. The slot system is disabled here to show different weather types.
