ProbTor and GLM Comparison

Here is a loop of the ProbTor overlayed on the MRMS Rotation Tracks (Upper Left), along with GLM (Lower Left), ENTLN (Lower Right) and Sandwich GOES-16 (Upper Right).

~80 minute loop over central Pennsylvania

The thing to take notice of in the lower left loop is how the GLM lightning flashes/events quickly ramped up just ahead of the highest ProbTor values (74%).  That GLM increase highlighted the intensifying updraft in the storm.  In addition, when taking a close look at the MRMS Rotation Tracks, you can see increases around the same time or just after the GLM events/flashes increase (possible lightning jumps).

One item that I did notice with the 9km GLM data with this storm is a few pixels of no data (notice it during the first half of the loop and again near the end as the storm moves directly over one of the spots where the lightning data doesn't match with the AWIPS grid.

Example of zero data due to the grid in AWIPS at 1809Z.
