   Areas affected...Southeast VA into Northeast NC

   Concerning...Severe potential...Watch unlikely 

   Valid 111615Z - 111815Z

   Probability of Watch Issuance...5 percent

   SUMMARY...Isolated to widely scattered thunderstorms may produce
   gusty winds and small hail through the afternoon. The severe risk is
   expected to remain low, and a watch is not currently expected.

   DISCUSSION...Isolated to widely scattered thunderstorms have
   developed early this afternoon as strong heating of a very moist
   airmass has resulted in weak to moderate destabilization across the
   region. Modest mid/upper west/southwesterly flow resides over the
   region as an upper trough lifts northeast across the Eastern
   Seaboard today. This is supporting effective shear magnitudes around
   20-25 kt, allowing for transient organized cells. Weak midlevel
   lapse rates and modest shear will likely limit longevity of any
   stronger/better organized cells. Nevertheless, cool temperatures
   aloft (around -10 C at 500 mb) and steepened low-level lapse rates
   could allow for gusty winds and small hail with the more intense
   cells. The severe risk is expected to remain low overall, and a
   watch is not expected.
