FAQs

How accurate is radar weather? ›

Weather surveillance radars such as the WSR-88D can detect most precipitation within approximately 80 nautical miles (nm) of the radar, and intense rain or snow within approximately 140 nm. However, light rain, light snow, or drizzle from shallow cloud weather systems are not necessarily detected.

The Weather Channel and 1Weather are also solid options, while Clime NOAA Weather Radar Live and Radarscope are a great way to access more detailed satellite views of the sky.

Precipitation moving perpendicular to the radar beam (in a circle around the radar) will have a radial velocity of zero, and will be colored grey. The velocity is given in knots (10 knots = 11.5 mph).

The Weather Channel has revamped its iPhone and iPod touch application to make it more personalized and relevant, with display live tiles on the home screen providing users with immediate access to radar, forecasts and new video. The app also offers users an immediate view of when to expect rain to start and stop.

AccuWeather's global leadership in providing life-saving weather information with Superior Accuracy demonstrated through #1 worldwide ranking in new temperature accuracy report, severe weather verifications, and use cases.

Trusted by 100 Million+ users across the world, the 1Weather app will keep you weather-ready, every day. Stay prepared with minute-by-minute forecast and precipitation up to 48 hours in advance.

Each weather app has access to varying sources of model data. Some are exclusive to their respected company, and some are borrowed from other sources and then molded to make them their own.

On a weather radar map, a tornado is usually indicated by a smaller area of red surrounded by a larger area of green. However, modern radar systems can also indicate debris balls, a sign of a tornado on the ground.

Purple indicates “range folding”— where the radar cannot determine the radial velocity. Velocity image of a large-scale weather system. denotes the approx. location of the radar.

What does a black dot mean on a weather radar? ›

Black dots represent divergence centers. Arrow length is proportional to wind speed. Negative (positive) Doppler velocities represent flow toward (away from) the radar. (

The Weather Channel is the World's Most Accurate Forecaster**. In addition to our daily forecasts, hourly details and 24-Hour Future Radar, you also can personalize your weather preferences from skin health to air quality index forecast and more.

Algorithms don't have that kind of discernment yet, which in turn makes app predictions like precipitation and storms somewhat imprecise. Algorithms also can't compete with the human experience of living somewhere and knowing how weather behaves in that particular area.

From iOS 8 to iOS 15, The Weather Channel was used as the weather data source of the app. Since iOS 16, Apple has used its own internal forecast data.

Most radar guns can accurately measure speeds up to several hundred miles per hour. However, effectiveness depends on several factors, including: The specific gun design. The distance between the radar gun and the target vehicle.

Algorithms don't have that kind of discernment yet, which in turn makes app predictions like precipitation and storms somewhat imprecise. Algorithms also can't compete with the human experience of living somewhere and knowing how weather behaves in that particular area.

Based on our observations, police radar guns can detect your speed from about a quarter mile to 700 feet away.

GPS is preferred for navigation and mapping because it offers accurate positioning globally, while radar is mainly used for short-range object detection and tracking.
