   ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PORTIONS OF THE SRN
   PLAINS...
   
   ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PORTIONS OF SERN
   KS...NERN OK...SWRN MO AND NWRN AR...
   
   ...CNTRL/SRN PLAINS...
   00Z ANALYSIS INDICATES THAT THE DRYLINE WAS BEGINNING TO RETREAT WWD
    AS LARGE SCALE HEIGHT FALLS CONTINUE ACROSS THE FOUR-CORNERS REGION
   AHEAD OF THE PRIMARY UPPER TROUGH IN THE WRN CONUS.  TSTMS THAT
   INITIATED ALONG THE DRYLINE HAVE LARGELY BECOME REMOVED FROM THE
   SOURCE OF CONVERGENCE AND ARE BEGINNING TO WEAKEN AS INHIBITION
   INCREASES.  GIVEN VARIOUS INTERACTIONS WITH THE OUTFLOW BOUNDARIES/
   TERRAIN...TSTMS MAY THRIVE THROUGH MID-EVENING...BUT THE SEVERE
   THREATS SHOULD GRADUALLY DIMINISH.
   
   UPPER LEVEL JET STREAK MIGRATING EWD THROUGH KS/NRN OK THIS EVENING
   WILL TRANSLATE INTO THE MID/LWR MS VLY LATER TONIGHT.  THE ASCENDING
   BRANCH OF THE LLJ WITHIN THE RIGHT ENTRANCE REGION OF THIS JET
   STREAK WILL INCREASE LATER THIS EVENING WITH AN AXIS FROM NWRN TX
   ACROSS OK INTO THE OZARK REGION.
   
   ELEVATED TSTMS ARE EXPECTED TO DEVELOP NEAR/AFTER 06Z FROM ERN KS
   SEWD INTO NWRN AR AS THE VERY UNSTABLE PARCELS SITUATED ACROSS SWRN
   OK REACH THE LFC.  MAGNITUDE OF ELEVATED CAPE AND EFFECTIVE SHEAR
   SUGGEST THAT A FEW UPDRAFTS WILL BE ORGANIZED WITH LARGE HAIL BEING
   THE PRIMARY SEVERE THREAT.  A SMALL AND LOOSELY ORGANIZED MCS MAY
   EVOLVE VERY LATE TONIGHT AND BE LOCATED OVER SWRN MO BY 12Z.
   
   ...MID-ATLANTIC TO SRN NEW ENGLAND...
   A FEW TSTMS CONTINUE TO ACCOMPANY THE COLD FRONT AS IT MOVES EWD
   ACROSS THE MID-ATLANTIC AND SRN NEW ENGLAND.  LOSS OF HEATING WILL
   CONTRIBUTE TO A STABILIZING BOUNDARY LAYER AND TSTMS SHOULD WEAKEN
   THROUGH THE EVENING.
