Hi there! I understand your Weather Underground app keeps closing right after you try to open it, even after you’ve reinstalled it. Let's try to get this sorted for you.

Since you’re using Linux with WebKit as your browser engine, is this app running as a web app in a browser or is it a native app on your system? That info will help me narrow down the steps.

Meanwhile, here are some general troubleshooting steps we can try:

1. Clear Browser Cache and Cookies:
Since you're on WebKit and Linux, clearing cache and cookies for the browser might help. Sometimes, cached data can cause apps or websites to misbehave.

2. Check for Browser Updates:
Make sure your browser and WebKit are up to date. Outdated versions could cause compatibility issues.

3. Disable Browser Extensions:
Some extensions might interfere with the app loading properly. Try disabling them temporarily and see if the app opens.

4. Try a Different Browser:
If possible, see if the Weather Underground site or app opens correctly in another browser on your Linux system.

5. Check Network Connection:
A disrupted or slow network can cause the app to hang or close. Verify your connection is stable.

If you’re running a native Linux app (less common for Weather Underground), or a web app installed as a desktop app, let me know so I can provide more tailored steps like clearing local app data or checking logs.

Could you tell me a bit more about the exact setup? That way, I can guide you more precisely. Are you seeing any error messages when it closes?

Looking forward to your reply so we can get this fixed!
