CI Provides Lead Time on Cell Just South Of Memphis.

Below in the upper right is the CI product. The cursor readout shows a value of 58% with a cell just southeast of the city of Memphis in Shelby County at 1945 UTC.

The radar image from KNQA below shows the cell with 41 dBZ at 2003 UTC exiting far southern Shelby County. This provided about 18 minutes of lead time for the 35 dBZ-plus echo. This made sense, as the modified NUCAPS sounding (not shown) showed a little more than 400 J/kg of CAPE in that area, ahead of the pre-frontal surface trough. JJW
