![]() As with super-res velocity, green is motion towards the radar and red indicates motion away from the radar. When storms are moving quickly, this makes it easier to spot green/red velocity couplets that are indicative of rotation and which might be masked out by the motion of the storm. Super-res storm relative velocity is super-res velocity with the average storm motion subtracted out. Super-res velocity is available at four different tilts or beam angles, with tilt 1 being the lowest to ground level. It provides the highest-resolution reflectivity available from NEXRAD radars to a distance of 230 kilometers from the radar. The super-res velocity product has a resolution of 0.25 kilometers by 0.5 degrees. But it gives you a fairly good idea which way a storm is heading. Note that the radar can only detect the component of the velocity vector along the radar beam, so this isn’t a full picture of the wind field. They can be difficult to interpret without training and experience, but Doppler velocity products can be used to detect the overall movement of a storm as well as relative motion within the storm itself, such as rotation. Negative values (green in RadarScope) indicate motion toward the radar, while positive values (red in RadarScope) indicate motion away from the radar. The velocity products in RadarScope use the Doppler effect to determine how fast the particles in the air are moving relative to the radar itself. While the top end Tier 2 package adds in hail and shear contouring (the latter necessary for tornado formation), as well as multi-platform use and a 30-day radar archive.īut even for just $9.99 for the app alone without the tiered options, the standard data is fantastic.Doppler velocity products indicate storm motion toward or away from the radar. Stepping up to the Pro Tier 1 subscription for $9.99 per year gets you longer animations and lightning data (a must for outdoor enthusiasts), dual pane capability, and inspection tools. ![]() You have access to every single radar product that the pros do, at practically the same time they see them-along with up to the minute warning information. Available on Android and iOS for $9.99 and Windows or Mac for $29.99, this app is one of the quickest updating around. If none of the above weather apps have what you’re looking for, and you’re willing to spend money on a quality professional weather radar app or website that storm chasers use, hands down our top recommendation is RadarScope. However, the smoothing is addressed in a premium radar option, which offers higher resolution imagery and the previously mentioned forecast radar imagery. ![]() In turn, this may cause some inaccuracy in the data, especially when zoomed in. If we had to pick a negative with this one, it’s that the app smooths radar imagery too much to make it look nice on the screen. It also has an innovative future radar option, which attempts to forecast future storm movement up to six hours in advance using the company’s proprietary short-range modeling. Zooming in and out of imagery is fluid, and the satellite map used allows you to zoom down to street level. According to Forecast Advisor, The Weather Channel is consistently rated as the most accurate weather app for many cities across the country.Īlthough it’s a more general weather app, there are some great radar features that we think are worth mentioning. The Weather Channel’s app continues to be one of our top radar apps for 2023, and in our opinion, it’s the best actual mobile weather app.
