By monitoring the cell via All-Tilts BR\/BV\/CC\/ZDR and GOES-East Satellite Imagery via Mesosector, I was able to get roughly 5 additional minutes of lead time on my warning (ProbHail was less than 45% by warning issuance). A good reminder as to how the ProbSevere suite is best utilized as an additional tool, and not necessarily the deciding factor in warning ops, especially in freshly forming cells.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-medium wp-image-18264\" src=\"https:\/\/inside.nssl.noaa.gov\/ewp\/wp-content\/uploads\/sites\/22\/2019\/06\/Screenshot-from-2019-06-06-21-03-54-900x592.png\" alt=\"\" width=\"900\" height=\"592\" srcset=\"https:\/\/inside.nssl.noaa.gov\/ewp\/wp-content\/uploads\/sites\/22\/2019\/06\/Screenshot-from-2019-06-06-21-03-54-900x592.png 900w, https:\/\/inside.nssl.noaa.gov\/ewp\/wp-content\/uploads\/sites\/22\/2019\/06\/Screenshot-from-2019-06-06-21-03-54-768x505.png 768w, https:\/\/inside.nssl.noaa.gov\/ewp\/wp-content\/uploads\/sites\/22\/2019\/06\/Screenshot-from-2019-06-06-21-03-54-600x394.png 600w, https:\/\/inside.nssl.noaa.gov\/ewp\/wp-content\/uploads\/sites\/22\/2019\/06\/Screenshot-from-2019-06-06-21-03-54.png 1415w\" sizes=\"auto, (max-width: 767px) 100vw, (max-width: 1200px) 60vw, 720px\" \/><\/p>\n<p>Quick update: The earlier warning did verify with quarter-sized hail.
