   AREAS AFFECTED...NH...WRN/SRN  ME
   
   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 
   
   VALID 031608Z - 031745Z
   
   TRENDS CONTINUE TO BE MONITORED.  A WW COULD BECOME NECESSARY BY THE
   17-18Z TIME FRAME.
   
   IN THE WAKE OF STRONG/SEVERE CLUSTER OF STORMS...LIKELY TO SPREAD
   ACROSS THE HOULTON/CARIBOU AREAS INTO NEW BRUNSWICK BY/SHORTLY AFTER
   17Z...AND...STILL AHEAD OF ASSOCIATED WEAK MID-LEVEL IMPULSE...THE
   BOUNDARY LAYER CONTINUES TO DESTABILIZE WITH STRONG HEATING.  LATEST
   OBJECTIVE ANALYSIS INDICATES THAT INHIBITION REMAINS...BUT WITH
   ADDITIONAL INSOLATION...CAPPING IS EXPECTED TO BECOME NEGLIGIBLE BY
   18/19Z ACROSS NEW HAMPSHIRE INTO WESTERN MAINE.  FORCING/INSTABILITY
   COULD EVENTUALLY BECOME SUPPORTIVE OF AN ADDITIONAL STORM CLUSTER OR
   LINE IN WEAK TO MODERATELY SHEARED WESTERLY FLOW REGIME.  AND...THE
   MOST VIGOROUS STORMS PROBABLY WILL BE CAPABLE OF PRODUCING LARGE
   HAIL...IN ADDITION TO STRONG SURFACE WIND GUSTS.
   
   FARTHER UPSTREAM...ISOLATED CONVECTIVE DEVELOPMENT IS EVIDENT TO THE
   LEE OF THE LOWER GREAT LAKES...ACROSS PARTS OF NEW YORK STATE. 
   BUT...MORE SIGNIFICANT THUNDERSTORM POTENTIAL...IF ANY...MAY AWAIT
   SOUTHEASTWARD ADVANCEMENT OF COLD FRONT OUT OF ONTARIO LATER THIS
   AFTERNOON.
