Today in the NOAA HWT EWP in Norman we have been watching a line of cu over the TX Panhandle. At 1932 UTC we first noticed the CI "pre-cloud growth" and the "likely" indications. It was interesting to note however that the "likely" was associated with cloud-top cooling rates in the -4 to -7 range, but the "pre-cloud growth" was associated with greater values of cloud-top cooling rates of around -9. Eventually the area of -9 became the first convective initiation spot, and those values increased to -14 before we saw the first 35 db echo. The first 35 db echo showed up at 1955 UTC, which was 23 minutes later. At 2025 UTC a 1" hail report was logged with that same storm.
One other point to note was that we were monitoring the products on the web site (http://cimss.ssec.wisc.edu/snaap/convinit/quicklooks2.php) and estimated that the CI indications were approximately 3 minutes faster than the LDM feed into AWIPS.
