   NWS STORM PREDICTION CENTER NORMAN OK
   1030 AM CST FRI MAR 02 2012
   
   AREAS AFFECTED...PARTS OF ERN IND...NERN KY...MUCH OF OH AND
   ADJACENT WEST VIRGINIA
   
   CONCERNING...SEVERE POTENTIAL...WATCH LIKELY 
   
   VALID 021630Z - 021800Z
   
   A WATCH IS NOT NECESSARILY ANTICIPATED IN THE NEAR TERM...BUT ONE
   PROBABLY WILL BE NEEDED LATER THIS AFTERNOON.
   
   THE SEVERE HAIL POTENTIAL ASSOCIATED WITH STORMS SPREADING
   NORTHEASTWARD WITHIN AN ELEVATED WARM ADVECTION REGIME...IN ADVANCE
   OF THE SURFACE WARM FRONT LIFTING NORTHWARD THROUGH THE OHIO
   VALLEY...MAY BE LIMITED ENOUGH TO PRECLUDE A SEVERE THUNDERSTORM
   WATCH ISSUANCE.  HOWEVER...THE RISK FOR SEVERE STORMS IS EXPECTED TO
   INCREASE LATER THIS AFTERNOON...AS THE WARM SECTOR OF A DEEP SURFACE
   CYCLONE...MIGRATING NORTHEAST OF THE MIDDLE MISSISSIPPI VALLEY INTO
   THE GREAT LAKES REGION...ADVECTS NORTHEAST OF THE LOWER OHIO VALLEY.
    AT THE PRESENT TIME...IT APPEARS THAT A TORNADO WATCH COULD BECOME
   NECESSARY CLOSER TO THE 21-22Z TIME FRAME.
