VALID 100100Z - 101200Z

...THERE IS A SLGT RISK OF SVR TSTMS FROM NERN UT/SERN ID EWD INTO
SWRN MN/IA/PARTS OF NWRN IL...

...ERN WY/SRN SD/NEB INTO IA AND VICINITY...
POST-FRONTAL THUNDERSTORMS CONTINUE ACROSS PARTS OF SWRN SD AND INTO
ERN WY/THE NEB PANHANDLE...WHERE NELY UPSLOPE FLOW IS SUPPORTING
PERSISTENT CONVECTION WITHIN SUFFICIENTLY-UNSTABLE ENVIRONMENT. 
THOUGH DEGREE OF SHEAR WILL CONTINUE TO SUPPORT ORGANIZED/SUPERCELL
STORMS...POST-FRONT/ELEVATED NATURE OF CONVECTION SUGGESTS THAT HAIL
SHOULD REMAIN THE PRIMARY SEVERE THREAT -- PARTICULARLY AFTER DARK.

FURTHER E...STORMS CONTINUE ACROSS N CENTRAL AND NERN NEB AND INTO
FAR SERN SD/NWRN IA...WHERE LOW-LEVEL JET WILL CONTINUE TO
INTENSIFY.  EXPECT STORM COVERAGE TO INCREASE SIGNIFICANTLY OVER THE
NEXT FEW HOURS...THOUGH GREATEST CONVECTIVE COVERAGE SHOULD REMAIN N
OF SURFACE BAROCLINIC ZONE -- I.E. ACROSS NERN NEB...SERN SD...AND
THE NERN HALF OF IA.  AGAIN -- GIVEN MAINLY ELEVATED NATURE OF
CONVECTION...EXPECT MAIN THREAT TO BE HAIL...THOUGH LOCALLY
STRONG/DAMAGING WINDS WILL BE POSSIBLE WITH LESS ELEVATED STORMS IN
CLOSER PROXIMITY TO THE SURFACE FRONT.

...NRN UT/SERN ID/PARTS OF MT...
THUNDERSTORMS CONTINUE AHEAD OF PRONOUNCED VORT MAX CENTERED OVER
NRN UT ATTM.  COMBINATION OF MARGINAL BUT SUFFICIENT INSTABILITY AND
MODERATE MID-LEVEL FLOW ASSOCIATED WITH THIS FEATURE SUGGESTS THAT
STRONG/LOCALLY-SEVERE STORMS REMAIN POSSIBLE.  THOUGH THREAT SHOULD
EVENTUALLY BEGIN TO DIMINISH...EXPECT AT LEAST SOME SEVERE THREAT TO
LINGER THROUGH THE REMAINDER OF THE EVENING -- PARTICULARLY ACROSS
PARTS OF SWRN WY AND VICINITY.
