[Help] How To Get Accurate Weather Data w/ Location Services Off

Weather on watch faces is not updating for my location unless I have location services turned on on my phone (my LG V20 wouldn’t last 10 hrs if I left that on). No instructions on the syntax for manually setting location in Facer. Faces still show old temperature values from the last time I had time I had location services on, even after days have gone by. If it has a location scored, why isn’t it updating temperature?
