AREAS AFFECTED...ERN SD...NERN NEB...NWRN IA AND SWRN MN

CONCERNING...SEVERE THUNDERSTORM WATCH 319...

VALID 290203Z - 290300Z

SEVERE THUNDERSTORM WATCH 319 IS SET TO EXPIRE AT 0300 UTC. 
HOWEVER...AN ADDITIONAL WEATHER WATCH MAY BE NEEDED FOR PORTIONS OF
THE AREA.  

A COUPLE OF SUPERCELLS LOCATED ALONG THE MO RIVER FROM SIOUX CITY TO
NEAR SIOUX FALLS ARE EXPECTED TO GRADUALLY DIMINISH THROUGH 0300
UTC.  THE 00 UTC OMAHA SOUNDING SHOWED AN INCREASING CAP BUILDING
NWD BENEATH UPPER LEVEL RIDGING.  THE SUPERCELLS INFLOW WILL LIKELY
CONTAIN MORE AND MORE INHIBITION WITH TIME...AND THE CELLS SHOULD
DIMINISH.

MEANWHILE...ISENTROPIC LIFT IS BEGINNING TO INCREASE FROM ERN SD
INTO SRN MN ALONG NOSE OF A SWLY LOW LEVEL JET DENOTED BY EXPANDING
BANDS OF TSTMS.  THESE STORMS SHOULD CONTINUE TO INCREASE IN AREAL
COVERAGE/INTENSITY OVER THE NEXT SEVERAL HOURS FROM ERN SD...SERN ND
INTO SWRN MN AND PERHAPS NRN IA.  THE DEEP LAYER SHEAR ACROSS THE
REGION IS MORE THAN SUFFICIENT FOR SUPERCELLS...AND GIVEN THE
MOISTENING MIDLEVELS...AMPLE ELEVATED INSTABILITY WILL EXIST FOR
LARGE HAIL.
