Lightning Stoplight in AWIPS

While utilizing stoplight for IDSS activities. I noticed a few mapping errors in the AWIPs version. The first example comes from a lightning strike detected by ground-based networks underneath the anvil ahead of the storm. Stoplight correctly highlighted this strike, however on the AWIPS display it highlighted the adjacent grid (Figure 1). The strike occurred just northwest of McDade.

While comparing the CAVE lightning stoplight with the webviewer, it appeared as if they did not match one another. Below is an example of what was seen while viewing the CAVE version (figure 2) versus what was seen on the web viewer (figure 3). The webviewer indicated that the radius of concern had been lightning free for 30 minutes, whereas the cave version held on to some for longer.
