   ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS THE UPR MS
   VLY...MIDWEST...AND CNTRL PLAINS...
   
   ...UPR MS VLY TO WRN GREAT LAKES...
   VIGOROUS SHORT WAVE TROUGH AND ASSOCIATED ND SFC LOW ARE EXPECTED TO
   CONTINUE TO TRACK ENEWD ACROSS NRN MN AND INTO SCNTRL CANADA THROUGH
   EARLY THURSDAY. WHILE SYSTEM BEGINS TO UNDERGO OCCLUSION PRONOUNCED
   MID LEVEL HEIGHT FALLS AND STRONG MASS TRANSPORT AHEAD OF THE SFC
   LOW AND ASSOCIATED FRONTAL ZONES WILL MAINTAIN THE THREAT OF
   SCATTERED SEVERE TSTMS ACROSS MN AND WI THROUGH LATE TONIGHT.
   
   ONE LARGE CLUSTER OF ONGOING SEVERE STORMS APPEARS TO BE LOCATED
   NEAR FRONTAL TRIPLE POINT ACROSS CNTRL MN AT THIS TIME. THIS
   ACTIVITY IS BEING SUSTAINED BY STRONG DYNAMIC FORCING AND WARM AIR
   ADVECTION ON THE NOSE OF LOW LEVEL JET. HOWEVER...STORMS APPEAR TO
   BE IN THE PROCESS OF OUTRUNNING WARM SECTOR AIR MASS RECOVERY AND
   STABLE ELY FLOW ORIGINATING OVER LAKE SUPERIOR AND SPREADING ACROSS
   THE ARROWHEAD REGION SHOULD LIMIT SEVERE POTENTIAL TO MOSTLY HAIL AS
   STORMS SPREAD EAST ACROSS NERN MN AND NRN WI.
   
   FARTHER SOUTH...A NUMBER OF SUPERCELLS HAVE DEVELOPED IN THE WARM
   SECTOR AND AHEAD OF THE COLD FRONT OVER SRN MN. ALTHOUGH SOME OF
   THESE CELLS HAVE STRUGGLED TO PERSIST FROM LATE AFTERNOON INTO EARLY
   EVENING...PERHAPS DUE TO A STRONG CAP...NEW ACTIVITY NOW APPEARS TO
   BE TAKING HOLD ACROSS SWRN MN/NWRN IA ATTM. AIR MASS AND SHEAR AHEAD
   OF THIS ACTIVITY WILL REMAIN VERY SUPPORTIVE FOR SUPERCELLS WITH
   VERY LARGE HAIL AS WELL AS A COUPLE OF TORNADOES.
   
   ...IA/KS/MO...
   A BROKEN BAND OF STRONG TO SEVERE STORMS EXTENDS SWWD FROM WCNTRL IA
   ACROSS SERN NEB...AND INTO CNTRL KS. THIS CONVECTION INITIATED AS
   FRONTAL CIRCULATION SPREAD INTO VERY UNSTABLE AND HOT AIR MASS OVER
   THESE AREAS. WITH FRONTAL ZONE NOW STALLING ACROSS THE REGION...AND
   SLIGHTLY WEAKER LARGE SCALE FORCING ON THE SRN EDGE OF MID LEVEL
   WIND MAX...ACTIVITY APPEARS TO BE PRIMARILY DRIVEN BY STRONG
   INSTABILITY IN A MARGINALLY SHEARED ENVIRONMENT. STRENGTHENING
   NOCTURNAL LOW LEVEL JET IMPINGING ON LEADING EDGE OF CONVECTIVELY-
   INDUCED COLD POOL...FROM KS NEWD...COULD CONTINUE TO SUPPORT STRONG
   TO SCATTERED SEVERE STORMS OVER THE NEXT FEW HOURS. IF WIDESPREAD
   STORMS CAN CONTINUE TO DEVELOP THROUGH THIS PROCESS...AN MCS MAY
   SPREAD EAST INTO NWRN MO LATER TONIGHT WITH A SEVERE WIND AND HAIL
   THREAT CONTINUING.
