Hi Justin,
I use the Saratoga template for my site and have for several years now; I do have a personal weather station operating that feeds data to it.
There was a time when I was using Virtual Weather Station (VWS) software with the template (have since switched to Weather Display). When using VWS I had many instances where VWS was not updating for various reasons. What I did when that happened was create a separate Home Page by editing the existing Home Page and deleting areas where “live” weather data from the station would occur. In essence just showing data obtained from outside sources e.g. NOAA, NWS, WU, etc.
So, from my experience I would say yes you can use a template (at least the Saratoga template) without having an actual station supplying data. I will say though that it was an effort to stay on top of it and make the changes when VWS failed. VWS failing was the main reason I switched to Weather Display.
Also, just a note – the link you have to your [future] web site needs to be edited.
It currently is
https://www.wxforum.net/www.northshoreweatherservice.com, you need to edit out the portion in the beginning that relates to this forum.
It should be
https://www.northshoreweatherservice.comAnyway, my $0.02
