![]() This image is an example of what you might see. The Probability of Hail and Probability of Severe Hail (POSH) can be viewed by touching the “i” icon on the storm attributes. work outside the county.34 KOAM - TV argues that Cable One's programming. The higher these reflectivity values are found above the freezing level, the higher the likelihood that the cell is producing hail. is unique.29 KSNF states that it has a very advanced weather radar system. After this data is ingested, the algorithm searches for reflectivity values of at least 45 dBZ above the 0☌ level. The HDA works by identifying the 0☌ level and the -20☌ level from model data. NOAA Weather Unofficial (Pro) (10 Similar Apps, 15 Features, 6 Review Highlights & 14,910 Reviews) vs RadarScope (10 Similar Apps, 4 Review Highlights & 9,762 Reviews). For a given storm, the HDA calculates the Probability of Hail, the Probability of Severe Hail (larger than an inch in diameter), and the Maximum Estimated Hail Size. NEXRAD radars use an algorithm known as the Hail Detection Algorithm (HDA) to assess the potential for hail. ![]() However, this will likely not be the case because these hail sizes are estimated at the height of the radar beam (which increases with distance from the radar), not what you may see at the ground. At first glance, you might interpret hail size as the size of the hail when a stone reaches the ground. These attributes are displayed in RadarScope by using storm tracks.
