   MESOSCALE DISCUSSION 1597
   NWS STORM PREDICTION CENTER NORMAN OK
   1145 AM CDT MON AUG 03 2015

   AREAS AFFECTED...MAINE / VT-NH / E-CNTRL AND NRN NY

   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 

   VALID 031645Z - 031845Z

   PROBABILITY OF WATCH ISSUANCE...40 PERCENT

   SUMMARY...A FEW CLUSTERS OF STORMS MAY INTERMITTENTLY BE CAPABLE OF
   DAMAGING STRAIGHT-LINE WINDS.  THE TIMING OF SEVERE STORMS AND THE
   SRN EXTENT OF GREATER STORM COVERAGE/INTENSITY LENDS SOME
   UNCERTAINTY AND TRENDS WILL CONTINUE TO BE MONITORED.

   DISCUSSION...VISIBLE SATELLITE IMAGERY SHOWS A LINEARLY ORIENTED
   BAND OF AGITATED CU ON THE EFFECTIVE FRONT LOCATED FROM NEAR THE ST.
   LAWRENCE SEAWAY SWWD INTO THE ADIRONDACKS.  SURFACE OBSERVATIONS
   INDICATE THE BOUNDARY LAYER CONTINUES TO WARM/DESTABILIZE AHEAD OF
   THE FRONT WITH TEMPS RISING INTO THE LOWER 80S AS OF 18Z.  DESPITE
   RELATIVELY POOR THERMODYNAMIC PROFILES SAMPLED BY 12Z AREA
   RAOBS...THE ADDITIONAL HEATING SINCE THEN AND A SLIGHT INCREASE IN
   LOWER TROPOSPHERIC MOISTURE /4-HR DEWPOINT RISES OF 2-4 DEG F/ ARE
   CONTRIBUTING TO WEAK BUOYANCY ACROSS NY INTO NEW ENGLAND AHEAD OF
   THE FRONT.  88D VAD DATA AT KCXX SHOWS VEERING SLY LOW-LEVEL WINDS
   VEERING TO WSWLY AND INCREASING TO 50 KT AT 4KM AGL.  AS A
   RESULT...SEVERAL STRONGER STORMS EMBEDDED WITHIN CLUSTERS OF STORMS
   WILL PROBABLY BE CAPABLE OF INTERMITTENT STRAIGHT-LINE WIND DAMAGE
   LATER THIS AFTERNOON.
