Where do Upweather forecasts come from?
The primary source of forecast information is the National Weather Service (NWS), a division of the National Oceanic and Atmospheric Administration (NOAA). The NWS forecasts are generally a blend of various computer models chosen by meteorologists with local expertise. The forecasters discuss their choices in an Area Forecast Discussion twice a day. This discussions can get very technical, but are a wonderful resource for those who wish to learn a little more.
Why can't I get weather for Canada (or Madagascar)?
The National Weather Service only produces detailed forecasts for the United States and some U.S. territories. Other forecast sources have global coverage (though with much less detail) so world-wide forecasts are certainly a possibility.
Can I see the forecast beyond 7 days?
Although 10-day forecasts are available from some sources, they are speculative at best.
What's up with the capitalization in the forecast discussion?
The forecast discussions are written by National Weather Service meteorologists in ALL CAPS with a variety of cryptic abbreviations. The Upweather version follows some fairly simple rules to improve the capitalization and expand abbreviations, but doing this well is trickier than you might think.
How does Upweather guess my location?
There are a number of possibilities. A rough guess at location is provided using GeoIP lookup. This varies in usefulness - it gives a rough location for a home DSL address but is useless for mobile devices. Then, Upweather will ask your browser or mobile device for a location, which may cause a dialog box to pop up asking if you want to share your location. See geolocation help for more information about browser geolocation.
