EVENT...SCATTERED TSTMS CAPABLE OF PRODUCING LOCALIZED HVY RAINFALL
APPROACHING FROM THE W ACROSS E OH
.
SATELLITE ANALYSIS AND TRENDS...IN RESPONSE TO MULTIPLE MID-LVL
DISTURBANCES..VORT MAXES AND S/WV SEEN ROTATING AROUND UPPER-LVL LOW
ACROSS THE LOWER GREAT LAKES..TSTMS HAVE DEVELOPED AND ARE MOVING EWD
ACROSS CENTRAL AND EASTERN OH THIS AFTERNOON AND ARE CAPABLE OF PRODUCING
HVY RAINS.  THESE STORMS ARE RELATIVE WARM-TOPPED WITH OVERSHOOTING TOPS
READING TEMPS AROUND -48C FROM IR IMAGERY AND BASED ON 12Z SOUNDING
EL WAS -28C..SO THIS PUTS CLOUD TOPS WELL ABOVE THAT.  FOR THE MOST
PART LVL MOISTURE HAS BEEN LACKING ACROSS W PA/N WV TDY BASED ON SFC
ANALYSIS..HOWEVER LATEST VALUES FROM GPS NETWORK SUGGESTS PW'S HAVE
RISEN TO NEAR 1.0".  IT APPEARS THAT SOME WEAK MOISTURE ADVECTION IS
OCCURRING AS 850 MB FLOW IS ALLOWING FOR TRANSPORT OF SLIGHTLY HIGHER
PWS POOLED ACROSS W TN TO BE ADVECTED INTO S AND E OH.
.
LOCALIZED HVY RAINS ARE THOUGHT TO BE THE MAIN CONCERN INSTEAD OF A
WIDESPREAD SITUATION.  RAINFALL AMOUNTS ACROSS S PA/N WV MAY BE BETWEEN
1-2" OVER THE NEXT FEW HRS WHICH POSES A BIT OF A CONCERN AS FFG VALUES
ARE RELATIVELY LOW ACROSS W PA AND N WV.
