This extension has many features and does require some patience setting it up. Well worth the time investment.
Only snag I ran into was with thumbs folder and cache. Re-read the docs, adjusted permissions and was good to go.
Very well done!
Only possible minor bug I found was the 'Forecast Update Time'. Enabling this displays a time in CDT time zone (server is EDT) and the time is oddly 3.5 hours ahead. All other times and features work as expected.
