This was a great clue that the updraft of the storm was strengthening and that a warning may be necessary. We used this information in conjunction with the Prob Severe which was showing an increasing trend to go ahead and pull the trigger on a severe thunderstorm warning. It was interesting that although Prob Severe was showing an increasing trend, it was not over the 80% threshold. In this case, the lightning jump algorithm alerted us more than Prob Severe whereas we&#8217;ve seen other cases today where Prob Severe has been high and the lightning jump algorithm has been lower than expected.<\/p>\n<p><a href=\"https:\/\/inside.nssl.noaa.gov\/ewp\/wp-content\/uploads\/sites\/22\/2015\/06\/LJA.gif\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-large wp-image-11859\" src=\"http:\/\/hwt.nssl.noaa.gov\/ewp\/internal\/blog\/wp-content\/uploads\/2015\/06\/LJA-1024x545.gif\" alt=\"LJA\" width=\"584\" height=\"311\" srcset=\"https:\/\/inside.nssl.noaa.gov\/ewp\/wp-content\/uploads\/sites\/22\/2015\/06\/LJA-1024x545.gif 1024w, https:\/\/inside.nssl.noaa.gov\/ewp\/wp-content\/uploads\/sites\/22\/2015\/06\/LJA-300x160.gif 300w, https:\/\/inside.nssl.noaa.gov\/ewp\/wp-content\/uploads\/sites\/22\/2015\/06\/LJA-768x409.gif 768w, https:\/\/inside.nssl.noaa.gov\/ewp\/wp-content\/uploads\/sites\/22\/2015\/06\/LJA-500x266.gif 500w\" sizes=\"auto, (max-width: 767px) 100vw, (max-width: 1200px) 60vw, 720px\" \/><\/a>-Helen Hunt<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Click on the animated gif below to see how the lightning jump algorithm increased from 0 sigma at 2210Z to 4 sigma at 2211Z to 8 sigma at 2212Z.
