   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 145
   CONTINUES.
   
   A SEVERE THREAT MAY DEVELOP ACROSS CNTRL AND NRN PA AS STORMS MOVE
   IN FROM THE WEST. THE SEVERE THUNDERSTORM WATCH IN NW PA WILL BE
   LOCALLY EXTENDED.
   
   THE STORMS ARE LOCATED NEAR A SFC LOW AND PRESSURE FALL/RISE
   COUPLET. THIS ALONG WITH LIFT ASSOCIATED WITH THE LOW-LEVEL JET WILL
   SUPPORT THE CONVECTION OVER THE NEXT FEW HOURS. OBJECTIVE ANALYSIS
   SHOWS A CAPPING INVERSION ACROSS THE REGION MAKING THE STORMS
   ELEVATED. HOWEVER...A FORWARD SPEED OF 55 TO 60 KT MAY RESULT IN A
   WIND DAMAGE THREAT AS THE LINE IN VENANGO AND MERCER COUNTIES MOVES
   SEWD INTO THE STATE COLLEGE AREA TONIGHT. STEEP MID-LEVEL LAPSE
   RATES MAY ALSO BE SUFFICIENT FOR HAIL WITH THE MORE INTENSE CORES.
