The transition from a LP to Classic Supercell was observed from 0-3 Z on June 3rd, 2007 just west of Patricia, TX. The first image, as viewed from southeast, shows early genesis of LP with saucer shaped Rain Free Cloud Base, slightly lowered updraft intake area with rotating Fractus Scud Cloud(s), and light precipitation. The second image reveals pronounced Wall Cloud lowering partially obscuring the RFD "Clear Slot". 
The third image is un-zoomed to show the gradual transition to Classic Supercell by denoting low level moisture transport from "Beavers Tail" (lower right), ragged slightly lowered Wall Cloud, and RFD "Clear Slot" with noted blowing dust to southwest.
The fourth image is driving quickly to the south of circulation center (to the right on image) to become better positioned on southeast side of storm but encountered large 2.5" diameter hail as shown hitting pavement and strong RFD winds estimated at 55-60 knots shown by blowing dust in background
. The last image is viewing the RFD (upper center) from the southwest side of Classic Supercell with heavy rain and hail core lower center and left.
