Quick Look: Weather HD on Roku provides static weather graphics from the National Weather Service.
The US Weather category provides nationwide radar mosaic plus 12 regional radar maps. These radar images were nearly a half-hour old at the time we viewed them, so don't depend on them for current conditions.
Under US Forecast Maps and Data you'll find a national weather forecast graphic, plus condition maps such as low temperature, precipitation probabilities, and weather hazards. When we reviewed the channel, the forecast graphic was over 12 hours out of date, even though an updated version had been posted on the National Weather Service website over an hour ago.
You'll also find several categories of satellite images: PACUS and CONUS, US Satellite, Earth Satellites 1 (North America, South America) and Earth Satellites 2 (Africa, Other Regions). You won't find any local weather conditions or forecasts on this channel, but for some reason there are Hawaii, Alaska, and Puerto Rico forecast maps and data. Rounding out the channel are images from the Japanese weather satellite Himawari-8.
Some of these graphics, and many more, are also available on Weather4us, which also provides detailed forecasts, current weather conditions, warning, and much more. The Weather Graphics private channel also provides some of these images, but as a looping time lapse instead of just a single image, and offers time lapse regional radar for a large number of sites around the U.S.
