   OVER THE NEXT HOUR WHERE MODERATE INSTABILITY IS IN PLACE WITH
   MLCAPE VALUES IN THE 1000 TO 2000 J/KG RANGE. INSTABILITY WILL
   INCREASE ACROSS MAINE AS THE MOIST AXIS MOVES EWD ENABLING A SEVERE

   ABOUT 50 KT OF 0-6 KM SHEAR WHICH COMBINED WITH STRONG LOW-LEVEL
   SHEAR PROFILES WILL BE SUFFICIENT FOR ROTATING STORMS CONTAINING AN
