Brian, my computers were indeed running the latest version of Weather Display (build 84, with the latest file dated November 12).
Fortunately, it was after Weather Display cross-over midnight that the tags got reset. It now appears that the only tags without data are:
- maxgustlastimediatehourtime == time that the max gust last prior 1 hour occurred
- maxhourrnt == time that the max rain last hour for the day occurred
