I was trying to figure out how to implement this well. One of my principles for this tool is to stay simple, and avoid trying to compete with the 'professional' tools like DUATS, ForeFlight, etc. While pulling and parsing TAFs for large airports is only a moderate work item, I fear the complexity I would add by trying to locate the nearest airport with a TAF and then trying to interpolate it.

Are you looking for something like--'should I fly in 4 hours?'. Knowing what people are looking for could help me keep the solution simple and effective.

Again, thanks for taking a look. The audience for such a tool is small, so I appreciate and any all feedback.
