The above image was produced by GRLevel3 software using NEXRAD Radar data from station KLOT.

ETVS Default Icon
The NMD iconsheet has two rows of five icons. The top row is shown when the mesocyclone does not extend down to the lowest velocity tilt. The NMD Strength Rank is used to select the column via the equation: (SR-1)/2.
The MESO iconsheet is shown on legacy volume scans. There are two icons: 2D detection and 3D detection.
The Hail iconsheet has five rows of four icons. Each row corresponds to the inches in the estimated hail size. Each column represents 0.25" increments.


Lightning Data has been added to the Peotone Local base reflectivity 2 (br2) GRLevel3 Radar. To keep the display (radar) readable, only one lightning bolt will show every 2 square miles! Use chart below radar to determine how much lightning has actualy occured. For example the larger the bolt the more recent the strike. While the color tells you aproximately how many strikes that one bolt represents. For example Purple is 1 bolt, Red is 2-3 bolts, Gold is 4-10 bolts and white is 11 or more!
