   DISCUSSION...SCATTERED STRONG TO SEVERE THUNDERSTORMS CONTINUE
   ACROSS WWS 62 AND 63. THESE STORMS ARE OCCURRING IN AN ENVIRONMENT

   HAIL AND DAMAGING WIND THREATS. ADDITIONAL STRONG TO OCCASIONALLY

   AS LOW-LEVEL SHEAR INCREASES THROUGH 02Z IN CONJUNCTION WITH A
   DEVELOPING LLJ. HOWEVER...AFTER 02Z...NOCTURNAL COOLING OF THE
   BOUNDARY LAYER WILL CAUSE STORMS TO GRADUALLY BECOME MORE
   ELEVATED...WITH LARGE HAIL BECOMING THE PRIMARY THREAT.
