AREAS AFFECTED...ERN NEB...WRN IA

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 211332Z - 211500Z

THE SEVERE THREAT WILL CONTINUE OVER THE NEXT 2 TO 3 HOURS ACROSS
ERN NEB AND WRN IA. LARGE HAIL AND ISOLATED WIND DAMAGE WILL BE
POSSIBLE WITH THE STRONGER CELLS. A WW WILL BE ISSUED SHORTLY.

NUMEROUS THUNDERSTORMS ARE ONGOING ALONG AN AXIS OF MODERATE
INSTABILITY. THE STORM ACTIVITY IS BEING SUPPORTED BY AN APPROACHING
UPPER-LEVEL TROUGH EVIDENT ON WATER VAPOR IMAGERY. A 50 KT MID-LEVEL
JET IS LOCATED ACROSS SWRN IA AND THIS IS CREATING VERTICAL SHEAR
FAVORABLE FOR SEVERE STORMS. AS DESTABILIZATION CONTINUES...THE
SEVERE THREAT SHOULD BE SUSTAINED THIS MORNING WITH LARGE HAIL AND
ISOLATED WIND DAMAGE POSSIBLE.
