For most lockscreens that have a weather widget, you do this: 1) Go to weather.yahoo.com and enter your location 2) Click on the RSS button on the right. Your address bar should look something like this: Code: http://weather.yahooapis.com/forecastrss?p=USKY0706&u=f The code after the "p=" and before the & is what you need. So in my case, it's "USKY0706". 3) Search in your theme's Lockbackground.html file or, in this case, the yahooweather.js file to find a spot that is marked "weather code" or "locale". Usually the creator marks it pretty clearly. Then replace what is there with your code, making sure to surround it with quotation marks. ("USKY0706") 4) Respring! Note that sometimes if you're in a smaller place, you might get the name of a different town. I'm at Berea, KY but my weather code is for Bighill, KY. Also, if you want Fahrenheit over Celsius, most themes have a field you can change for that. Just search and there should be a true/false attribute you can change.
