THUNDERSTORMS HAVE BEEN GRADUALLY INCREASING FROM WRN AROOSTOOK CNTY
SSWWD INTO EXTREME NRN OXFORD CNTY ME. ACTIVITY IS OCCURRING AHEAD
OF AN ADVANCING COLD FRONT AND TRENDS ARE BEING MONITORED FOR A
POSSIBLE WW.
STORMS HAVE DEVELOPED WITHIN THE WRN EDGE OF A LOW LEVEL MOISTURE
AND INSTABILITY AXIS WHERE SBCAPE IS 1500-2000 J/KG. THE AREA IS
WITHIN THE LEFT EXIT REGION OF AN UPPER LEVEL JET STREAK WHICH IS
PROVIDING DYNAMIC FORCING FOR LARGE SCALE ASCENT OVER THE AREA.
VISIBLE SATELLITE IMAGERY SHOWS THINNING CLOUDS AHEAD OF THE
CONVECTION SUGGESTING THAT ENHANCED DIABATIC HEATING AND ADDITIONAL
DESTABILIZATION IS LIKELY TO OCCUR INTO THE EARLY AFTERNOON HOURS.
ALTHOUGH MID LEVEL WINDS AND DEEP LAYER SHEAR ARE MODEST AT BEST
/20-25 KT WINDS AT 500 MB/...WATER VAPOR IMAGERY SUGGEST DRIER
ENVIRONMENT IN THE MID/UPPER LEVELS WHICH MAY ENHANCE MID LEVEL
LAPSE RATES AND POTENTIAL FOR HAIL AND STRONG GUSTS.
