Note that ST uses Weather Underground as their weather sources. If you don’t like the station being automatically chosen based on your zip code, you can specify a particular Personal Weather Station be used instead - at least with those SmartApps that ask you for your Zip Code.
The trick is to specify the desired station instead of entering a zip code. the syntax is “pws:STATIONID” - i use my own weather station by entering “pws:KMATYNGS2”.
And to get more frequent updates on your Virtual Weather Tile, search for the app “Pollster” - I set mine to poll every 10 minutes…
