The venerable U.S. weather app Wx, named a 2009 Mac Gem by Macworld magazine, is now available for iPhone! Wx displays current conditions, forecasts, alerts, and radar for U.S. locations using high fidelity XML data from the National Weather Service.
Wx is designed for two types of customers: serious weather watchers who want detailed information and facts with no fuss, and casual users who want a fast, clean, and functional weather app that has low memory overhead and low CPU/battery usage.
Wx lets you set up locations on an embedded map, guiding you to choose nearby NWS observation sites (over 1700 available in the U.S. and its territories), nearby NEXRAD radar sites, and nearby city- and county-based alert zones.
Wx is crafted with attention to detail by a pro developer. The app has multiple levels of redundancy to handle severe weather events, and offers network settings for both Wi-Fi and 3G operation to fine tune performance and bandwidth needs.







Wx sets up a 7-day summary "point" forecast customized for the specific latitude and longitude of each location, and a 7-day “pro” forecast that graphs temperature (actual and apparent), dew point, relative humidity, cloud cover, wind speed, wind direction, gust speed, 12-hour probability of precipitation, 6-hour liquid precipitation amount, and 6-hour snow amount.
Wx’s pro forecast is also latitude/longitude based, and is about as good as it gets if you need to plan work, sports, hobbies, and outdoor activities based on upcoming weather. With their high spatial resolution, the point and pro forecasts are especially useful in coastal and mountainous regions, where typical zone forecasts can be inaccurate. Wx backs these forecasts up with a regional forecast bulletin for additional information.
Wx also lets you bookmark and setup weather maps for quick reference. Choose from 18 default NWS maps and images, or provide the URL for any map of your choice and load it right in the app! If you have preferred weather providers, you can load your favorite maps and images right in Wx and keep them handy.

FAQ:
Can the app display alternate units, such as temperature in Celcius or wind in knots? Right now the app only displays the US standard units available in the NWS data feeds. An option for alternate units may be added in the future.
How do I setup a custom weather map/image? When viewing a map/image in Safari, tap and hold on the image until a popup appears, then select "Copy". Go into Wx to setup a map, activate the text cursor in the URL field, press and hold until the copy/paste popup appears, and select "Paste".
Runs on any iPhone or iPod Touch with iOS 4.1 or later.
