For the first time, we have storms in an LMA domain strong
enough to produce images on lightning jump grid.
The four-panel image below contains a 3-sigma lightning jump
(top left: orange fill region) the pGLM lightning grid (top right: max flash
extent density as high as 18 flashes per min), MRMS reflectivity at -10 C
(bottom left), and ProbSevere (94%) overlaid on MRMS MESH (bottom right).

This particular combination has provided a couple ideas for
lightning jump algorithm development.
(1) inclusion of metadata similar to the mouse-over ability of the
ProbWarn product. The mouse over for the
lightning jump should contain the current flash rate as well as the degree of
jump in sigma. (2) Combination with a product similar to ProbWarn (if not, the
ProbWarn product itself. This could
provide the forecaster information from satellite, lightning and radar all-in-one product. The advantage this provides is that
approaches a forecaster-over-the-loop type product without becoming a “black
box” as all the information that is part of the product is also provided as
metadata. I look forward to working with
CIMSS-WI and other researchers on this type of development.
