Air Masses -> Air Fronts -> Weather Events

Weather like this is just goofy without anything driving it.

simple, dominating weather is rain, doesn't need a specific front:



as explained, rather handily, in the manual:

The actual weather is partly determined by the Climate Zone. This indicates the type of weather that might be expected to dominate in that zone at that time of the year. The chart can be accessed by clicking on ‘Show Dominating Weather Table’ on the Current Weather Conditions screen.

These default weather conditions are then modified as weather fronts move across the map. A front can bring a different weather type to that expected so the actual weather may improve, or worsen, compared to what is expected.
