A strong PGLM surge was noted just before issuing a warning. A strong to severe thunderstorm developed over the southern suburbs of Denver. The cell had a history of nickel sized hail over south Denver. An boost came in the form of an outflow boundary coming in behind the cell. A warning was issued. Unfortunately, it appears that the Lightning Jump algorithm was a no-show just before the warning was issued.
