TSTMS ON NORTHERN EDGE OF CWA DON'T SEEM TO BE GROWING VERY FAST. THEY MAY NEVER FILL IN ENTIRELY SINCE 12Z RAOBS SHOWED DRYING UNDERWAY ALOFT. SPC POINTS OUT THEY MAY NOT BE REACHING SFC AIR BECAUSE OF A CAP. BUT...IF THEY EVER BREAK THROUGH TO THE EXTREMELY HIGH DEWPOINTS AND INSTABILITY AT SFC...THEY WILL PROBABLY EXPLODE. THUNDERSTORMS BOUNDED TO NORTH BY DRY SFC ADVECTION. MODELS SEEM TO BE A LITTLE FAST DEVELOPING THIS COMPARED TO WHAT LAPS SHOWS. BUT THEY ARE NOT TOO BAD AND ALL AGREE PRETTY WELL.
