Hunter Research and Technology has rolled out a trio of updates its Wx weather app (http://www.hrtapps.com/wxmac/) that displays current conditions, forecasts, warnings, and radar for U.S. locations using XML data from the National Weather Service. It's available for the Mac, iPhone, and iPad.

Wx helps users set up locations on an embedded map, guiding them to choose nearby NWS observation sites, nearby NEXRAD radar, and nearby city- and county-based alert zones. The app sets up a seven-day summary "point" forecast customized for the specific latitude and longitude of the 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 six-hour snow amount.

Wx also lets users set up weather maps for quick reference. Users can choose from over 40 default NWS maps and images, or provide the URL for any map of interest and load it right in the app. The update has all new download and processing engines, and is faster than ever.

Wx for Mac 6.2.1 is available on the Mac App Store for US$11.99. The app runs on OS X 10.6 or later. On the Apple App Store, Wx for iPhone 2.0 is available for $2.99, and Wx for iPad 2.0.1 is available for $3.99. Both iOS apps run on iOS 6.1 or later.
