...THERE IS A SLGT RISK OF SVR TSTMS OVERNIGHT FROM NW KS/CENTRAL
NEB TO MN....

...CENTRAL/NRN PLAINS AREA TONIGHT...
A BROKEN BAND OF PRE-FRONTAL THUNDERSTORMS IS MOVING EWD ACROSS NW
MN/SE ND/ERN SD.  THIS CONVECTION SHOULD PERSIST FOR SEVERAL MORE
HOURS AS CONVECTIVE OUTFLOWS CONSOLIDATE AND ENCOUNTER A CORRIDOR OF
MODERATE INSTABILITY /MLCAPE VALUES NEAR 1500 J/KG/ FROM ERN SD INTO
NW MN. ADDITIONALLY...THE LARGER SCALE ENVIRONMENT WILL REMAIN
SUPPORTIVE OF A FEW SEVERE STORMS AS A LOW-AMPLITUDE SHORTWAVE
TROUGH EJECTS ENEWD FROM THE CENTRAL DAKOTAS TO NW MN...AND AS SSWLY
LLJ INCREASES TO 40-50 KT WITHIN THE WARM SECTOR.  AFTER ABOUT
06Z...THE SEVERE THREAT SHOULD DIMINISH DUE TO WEAKENING INSTABILITY
AND INCREASING CONVECTIVE INHIBITION FOR BOUNDARY LAYER BASED
PARCELS.

FARTHER SW...CLUSTERS OF STRONG/SEVERE THUNDERSTORMS ARE ONGOING
ACROSS NW KS INTO S CENTRAL NEB.  THIS CONVECTION FORMED EARLIER IN
THE AFTERNOON INVOF A PRE-FRONTAL TROUGH WHERE LOW-LEVEL
CONVERGENCE/ASCENT WERE MAXIMIZED...AND WHERE SURFACE HEATING HAD
SUBSTANTIALLY WEAKENED THE CAP.  DESPITE A GRADUAL INCREASE IN
CONVECTIVE INHIBITION AFTER SUNSET...THIS CONVECTION MAY PERSIST
WELL INTO THE OVERNIGHT HOURS IN CONJUNCTION WITH A DEVELOPING SLY
LLJ.  ISOLATED LARGE HAIL/DAMAGING WINDS WILL REMAIN POSSIBLE UNTIL
ROUGHLY 04-06Z...AFTER WHICH TIME INSTABILITY SHOULD BECOME MARGINAL
AND THE SEVERE THREAT SHOULD DECREASE.
