PREDICTIVE HAIL AND LIGHTNING ICONS
• The hail prediction algorithm analyzes 3D weather data along with
temperature data to predict cells likely to be hail producers.
• The lightning prediction algorithm is similar to that for hail prediction,
but uses a slightly different reference altitude and dBZ threshold.
• There is very good correlation between lightning and hail predicted by
the RDR-4000 and that detected by ground-based systems.
• Predicted Lightning actually provides a leading indicator of future
lightning.
