Why not just use the 4 digit city code like you do with desktop widgets that report weather? You will get Temperature, cloud cover and precipitation, scattered showers, heavy rain, whatever. LFS would default to a minimum temperature of say 5C, unless we're going to have snow!
So if you're running a Fern Bay server, enter the city code for Kingston Jamaica or some other city in Jamaica, or anywhere in the world, or of course you could set the weather manually to whatever you want.
