There is no need to overwrite anything. Simply open up TotalCmdr and go to the HH 0409 WeatherCities xml. Click on 'File' and then 'Edit'. Scroll to where your city should be alphabetically and use the 'Enter' key to create a new blank line. Use the space bar to line up your entry and enter your city in the EXACT same format as the other cities listed, paying attention to spaces and punctuation marks. If you know your cities' NAM code great, but if not the zip code works just as well. Click 'File' then 'Save' and close out of TC. Usually your city should be ready to go right off the bat, but if you don't see it at first simply soft reset and it will be there. Hope I helped.
