Tornado Warning Prompted with Merged AzShear

Radar imagery f/ KGRK showed rotational low-level organization within the QLCS. While ProbSevere was putting near 80% for the wind threat with and increase to a 9% for a tornado threat. The Merged AzShear product was showing strong 1D pseudo-vorticity in the area of interest and was used to push the SVR warning w/ Tor possible tag up to a Tornado Warning. Immediately after issuing the warning the circulation seemed to fall apart, however, a couple minutes after the warning a report of a wall cloud with a rope tornado came in through the chat. Lead time may have been nill (also due to not having a Text Workstation up yet), but the warning seemed to have verified thanks to the dependency on the AzShear product. With a single-radar AzShear in operations it would have been possible to increase lead time.
