There are military, commercial, and private pilots. Each group has different look-ahead needs and approaches to planning and routing flights. If you want to give your brain a little exercise and learn new stuff, read up on various levels of pilots' licenses, endorsements, type ratings, etc. Add to that limits imposed by the aircraft (max operating altitude, speed, de-icing equipment, weight, etc.), airspace classes (how high can you/have to fly, will you be cleared to fly above weather), and jurisdictions (does my aircraft rating allow me to land at my destination given the weather forecast in that area). When you do that, you will understand how important weather forecasting is for pilots.
As for emergency services, it's good to know if/when things are going to get biblical, because you may need to transport additional machinery and personnel to another area, or you may need to prep temporary shelters.
