Got radar? You do now: Grab your mobile device and head to. Be sure to check out these video tutorials and frequently asked questions to help you get started using the site. Last summer, I wrote an article on how there were radar gaps in the United States and there were struggles to fill them all. We added new features to the radar viewer based on feedback we received from the public and emergency management community. The webpage is more reliable now that it's on an operationally supported system 24/7. The new page’s infrastructure allows for easy integration of new datasets, like satellite imagery, in the future and Radar animation loops can be saved, shared and used on social media Extremely heavy precipitation (values on the radar above 60dBz) is almost always a result of hail. However, there are some tricks you can use to make an educated guess about what might be falling. It also doesn’t discriminate directly between rain, snow, or other precipitation types. For times when a single radar is out of service, you still have coverage since radar beams overlap Ībility to customize data to any domain, and data layer preferences can be saved or bookmarked Radar cannot show clouds, it only picks up precipitation. More radar data, including 159 NEXRAD Doppler radars and 45 Terminal Doppler Weather Radars. However, phased array radar is expected to cost billions of dollars to implement, and with dual-polarization recently launched, it's unlikely to occur until well into the next decade.The radar webpage can be saved on your mobile device home screen just like an app, so you can use this powerful weather monitoring tool on the go.Īccess to certain dual-polarization radar products to help differentiate between precipitation types, such as rain and snow Instead of the 2-6 minutes each scan takes now in the Doppler radar system, phased array will be able to scan the same area in under a minute. It has risen in the Northwest, but continues below freezing at all the stations north of Tennessee and North. And meteorologists aren’t stopping with Doppler radar: new technologies like phased array radar will improve detection, and also dramatically increase scan times.

The NOWRAD Radar Summary maps are meant to help you track storms more quickly and accurately. What’s Next for Weather RadarĪs we’ve said already, radars have revolutionized weather forecasting, especially when it comes to severe weather. The Current Radar map shows areas of current precipitation. This is called a “debris ball,” and it's a telltale sign on a dual-pol radar of a tornado on the ground. See the latest Rhode Island Doppler radar weather map including areas of rain, snow and ice. See the latest Maine Doppler radar weather map including areas of rain, snow and ice.

The image on the right is called correlation coefficient, and the small circular blue area indicates an area of clear air encircled by objects detected in the air (the green color) and similarly shaped raindrops (shown in red). Tornadoes are more common in the United States than in any other country or state. Before dual-polarization, we’d only have the velocity data on the left, which would allow us to suspect a tornado on the ground, but not confirm it without a ground spotter. Tornadoes in the United States 1950-2019 A tornado strikes near Anadarko, Oklahoma.This was part of the 1999 Oklahoma tornado outbreak on May 3, 1999.
