   ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF THE GREAT
   PLAINS AND MS VALLEY...
   
   ...SYNOPSIS...
   AN UPPER-LOW CURRENTLY OVER SE CO WILL CONTINUE TO MOVE EWD INTO THE
   PLAINS THIS AFTERNOON...SPREADING STRONG LARGE-SCALE FORCING ACROSS
   THE REGION SUPPORTING WIDESPREAD THUNDERSTORM DEVELOPMENT THROUGH
   THE OVERNIGHT HOURS.
   
   ...CNTRL AND SRN PLAINS/LOWER MS VALLEY...
   AT THE SFC...A LOW IS PRESENT IN FAR SW KS WITH A QUASI-STATIONARY
   FRONTAL BOUNDARY EXTENDING NEWD INTO SE NEB. A DRYLINE EXTENDS SWD
   ACROSS WRN OK AND NCNTRL TX. STRONG STORMS ARE LOCATED ACROSS CNTRL
   AND ERN KS WHICH SHOULD MOVE NEWD INTO SE NEB/IA/SRN MN AND WRN MO
   LATE THIS AFTERNOON INTO THE EVENING. THIS CONVECTION SHOULD
   CONTINUE TO HAVE A HAIL AND WIND DAMAGE THREAT DUE TO THE
   INSTABILITY AND STRONG SHEAR. FARTHER SW ACROSS SWRN KS...STORMS
   SHOULD CONTINUE TO DEVELOP ALONG THE DRYLINE EAST OF THE SFC LOW
   THIS AFTERNOON SPREADING NEWD ACROSS CNTRL AND SRN KS. OBJECTIVE
   ANALYSIS SHOWS STEEP MID-LEVEL LAPSE RATES SPREADING NEWD ACROSS
   CNTRL KS WITH 0-6 KM SHEAR VALUES OF 60 KT....SUFFICIENT FOR
   SUPERCELLS WITH AN ISOLATED TORNADO THREAT...VERY LARGE HAIL AND
   WIND DAMAGE POSSIBLE WITH THE STRONGEST OF CELLS.
   
   FARTHER SOUTH ACROSS NCNTRL TX...ISOLATED STORMS HAVE INITIATED. IN
   OK...CONVECTIVE INITIATION SHOULD HOLD OFF ALONG THE DRYLINE UNTIL
   LATE AFTERNOON WHEN FORCING WILL BEGIN TO STRONGLY INCREASE AHEAD OF
   THE UPPER LOW. INITIALLY...STORM COVERAGE SHOULD BE ISOLATED BUT AS
   THE LOW-LEVEL JET INTENSIFIES THIS EVENING...A LINE SHOULD RAPIDLY
   DEVELOP ACROSS ERN OK AND NE TX. VERY LARGE HAIL AND AN ISOLATED
   TORNADO THREAT WILL BE POSSIBLE IF SUPERCELLS CAN REMAIN DISCRETE
   FOR SOME TIME IN THE EARLY EVENING. OTHERWISE...A LINEAR MCS SHOULD
   DEVELOP BY LATE EVENING WITH LARGE HAIL AND WIND DAMAGE LIKELY WITH
   THE STRONGER CELLS IN THE LINE. THE LINE SHOULD SPREAD EWD INTO AR
   AND DEVELOP SWD ACROSS EAST TX WITH A SEVERE THREAT CONTINUING LATE
   TONIGHT.
