   Concerning...Severe Thunderstorm Watch 325...

   Valid 270218Z - 270345Z

   The severe weather threat for Severe Thunderstorm Watch 325
   continues.

   SUMMARY...Some damaging-wind threat may persist into late this
   evening.

   DISCUSSION...A long-lived QLCS with a history of producing some wind
   damage continues to move northeastward late this evening. Downstream
   instability continues to diminish with the loss of diurnal heating,
   but given the rather well-organized nature of the QLCS, some
   damaging-wind threat may persist downstream, as it moves through a
   relatively moist environment where rather strong heating occurred
   earlier today. 

   Weakening deep-layer flow/shear with eastward extent and increasing
   MLCINH should eventually result in a definitive weakening trend
   later tonight. Additional downstream watch issuance is not
   anticipated, but local extension may need to be considered depending
   on convective trends over the next 1-2 hours.
