NWS STORM PREDICTION CENTER NORMAN OK
0151 AM CDT MON JUN 19 2006

AREAS AFFECTED...SRN IA/S CENTRAL AND SERN NEB/NRN KS/NRN MO

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 190651Z - 190845Z

EXPECT STORMS TO PERSIST -- ROUGHLY CENTERED ON THE MIDDLE MO VALLEY
-- OVER THE NEXT FEW HOURS.  THOUGH LOCAL THREAT FOR HAIL WILL
CONTINUE WITH STRONGER CELLS...WW NOT ANTICIPATED.

ELONGATED CLUSTER OF STRONG/LOCALLY SEVERE STORMS CONTINUES MOVING
ESEWD ACROSS SRN IA ATTM...WITHIN REGION OF ASCENT ASSOCIATED WITH
LEFT EXIT REGION OF UPPER JET. STORMS ARE ALSO INCREASING IN
COVERAGE ACROSS S CENTRAL NEB...WITHIN ZONE OF WARM
ADVECTION/ISENTROPIC LIFT N OF SURFACE FRONT.  

MARGINAL ELEVATED INSTABILITY IS INDICATED ACROSS THIS
REGION...WHICH COMBINED WITH PRESENCE OF LOW-LEVEL JET AND UPPER
SHORT-WAVE TROUGH/JET STREAK SHOULD SUPPORT A CONTINUATION OF
CONVECTION FOR THE NEXT FEW HOURS.  THOUGH MODERATELY-STRONG
MID-LEVEL WNWLY FLOW REMAINS SUFFICIENT FOR LOCALLY
ORGANIZED/ROTATING STORMS...ELEVATED/MARGINAL NATURE OF INSTABILITY
SUGGESTS ONLY A LIMITED HAIL THREAT.
