think the proliferation of weather apps on phones makes it to where nobody wants to go to a website anymore, they just want to press on an icon and have it display the info they need.
you have basically answered your question , has harsh as it or this sounds your wasting your time , 99.9% probably of your target audience is not interested in the finer details and own a smart device where the relevant information to them is at a click of an icon,button etc.. ask yourself what separates what you offer over the applications or information available to them instantly ? if you say i have radar images . are they interested do they understand exactly what is being displayed ? i have the forecast so does there pocket device , so does there computer, local media tv stations have it , local radio stations have it and so on .
importantly how does your website appeal to them is pretty , is it easy to understand, are the key points predominantly visible i.e how hot or cold will it be to tomorrow,is going to rain , is it going to snow . simple as they may sound thats what the average person is interested in outside the home weather enthusiast community ..
a predictable reply it may sound but you have to think outside your own interests , understanding and simplify it to something appealing.
personally i would just focus on your own needs , ive never had any interest in getting involved in anything for anyone outside my own home or interests after channeling time and effort in to a school project .
4 years ago i got involved in our local k12 international school and we bought a weather station and hooked it up to the web used kens saratoga template added links via the school website promoted it in parents newsletters etc it was complete waste of time has highlighted in a parent meeting session “but my phone shows the weather was a popular view “ now its just used for educational purposes internally occasionally with no public website .
lastly goto any smart device app store and your confronted with 100s or more applications what separates the popular ones from the rest is useability , ease of use and appearance (the key point is appearance as the expectation of a smart device is to be smart not old and out of date looking, distorted looking images, bad egg shaped appearance when it should be circular understand the importance of ergonomics especially using a smart device).
channel your knowledge into serving your own interests unless you have a niche ..
