This 4-panel satellite product display provides forecasters with an opportunity to view multiple satellite-based products in conjunction with each other and other observational products. In this particular display, we have transparent nearcast instability field with IR underlayed in the upper left, GOES-R CI and VIS in the upper right, OTD and VIS in the lower left, and NLDN lightning and PGLM total lightning in the lower right.
At 1845 UTC, the NearCast theta-e difference field (instability) had a nose of instability surging from central Texas into central Oklahoma. As a cu field developed within the unstable air, GOES-R CI began to target several cloud objects with probabilities of convective initiation greater than 50%.
By 1935 UTC, several cloud objects with higher probabilities did develop into mature storms within the axis of greatest instability as shown in the NearCast product. Lightning was also being mesaured with this developing convection. Meanwhile, high probabilities of CI, including some >90%, were being detected along the NearCast instability boundary into Oklahoma.
By 2010 UTC, a line of mature convection had developed along the NearCast instability boundary from north Texas into Oklahoma, where CI was detecting relatively high probabilities.
By 2130 UTC, many of these storms were becoming severe, one of which had an overshooting top detected, indicating a particularly strong updraft.
Participants this week have found this 4-panel display to be quite useful, as it helps to reduce the amount of displays they must toggle through. Additionally, many of these products are enhanced when used in conjunction with one another and other observation-based tools.
