MEAN LAYER HIGH IS ANCHORED WELL OFFSHORE OVER THE ATLANTIC WATERS. CONVECTION IS BEGINNING TO FIRE UP OVER INTERIOR NORTHEAST FLORIDA IN VICINITY OF UPPER LEVEL SHORTWAVE TROUGH AS EXTENSIVE FOG/CLOUDS THIS MORNING HAS DELAYED ONSET OF CONVECTION ACROSS SOUTHEAST GEORGIA. THE INTERACTION OF TEMPERATURES IN THE 90S AND DEWPOINTS IN THE 70S HAS YIELDED SURFACE-BASED LI READINGS OF -5 TO -8. THUNDERSTORMS WILL CONTINUE TO RAMP UP AS THE AFTERNOON UNFOLDS AND ANTICIPATE THUNDERSTORMS TO INITIATE CLOSER TO THE ATLANTIC COAST AS THE ATLANTIC SEA BREEZE SLOWLY ADVANCES INLAND. THUNDERSTORMS WILL LIKELY FOCUS OVER THE INTERIOR THIS EVENING BEFORE DISSIPATING.
