   ...THERE IS A SLGT RISK OF SVR TSTMS FROM THE UPPER MS VALLEY AND
   GREAT LAKES SSWWD TO THE ERN OK/NW AR AREA....
   
   ...SYNOPSIS...
   THE DEEP MID LEVEL TROUGH CURRENTLY OVER CA/NV WILL EJECT ENEWD OVER
   THE PLAINS AND UPPER MS VALLEY BY TOMORROW NIGHT IN RESPONSE TO
   ANOTHER TROUGH MOVING ESEWD TOWARD THE PAC NW FROM THE GULF OF
   ALASKA.  A SURFACE LOW INVOF NE NEB/SE SD EARLY IN THE PERIOD IS
   FORECAST TO DEVELOP ENEWD TOWARD UPPER MI WHILE A TRAILING COLD
   FRONT AND REMNANT LEE TROUGH MOVE EWD ACROSS THE ERN PLAINS DURING
   THE DAY AND THE MID MS VALLEY LATE IN THE PERIOD.  THE PRIMARY
   THUNDERSTORM THREAT AREAS WILL BE IN ASSOCIATION WITH THE SURFACE
   LOW AND COLD FRONT ACROSS THE MS VALLEY REGION.
   
   ...MS VALLEY REGION...
   A BROAD/RELATIVELY MOIST WARM SECTOR IS ALREADY ESTABLISHED ACROSS
   THE GULF STATES AND AS FAR N AS KS EARLY THIS MORNING WITH DEWPOINTS
   RANGING FROM THE MID 60S TO LOWER 70S. THIS MOISTURE WILL CONTINUE
   TO SPREAD NWD TODAY AND TOMORROW...RESULTING IN A MOIST/UNSTABLE
   WARM SECTOR TOMORROW FROM THE GREAT LAKES SWD TO THE GULF COAST. 
   WITH MLCAPE VALUES EXPECTED TO RANGE FROM 1000-2000 J/KG TOMORROW
   AFTERNOON IN CONJUNCTION WITH ROUGHLY 50 KT SWLY MID LEVEL FLOW
   THROUGH MUCH OF THE WARM SECTOR...THERE WILL BE A BROAD AREA WITH AT
   LEAST SOME THREAT FOR ORGANIZED SEVERE STORMS. THE MORE PROBABLE
   AREA FOR SEVERE STORMS WILL BE IMMEDIATELY IN ADVANCE OF THE SURFACE
   LOW ACROSS THE WI AREA...WHERE INSTABILITY AND VERTICAL SHEAR SHOULD
   BE SUFFICIENT FOR SUPERCELLS/BOWING SEGMENTS CAPABLE OF PRODUCING
   DAMAGING WINDS...LARGE HAIL...AND POSSIBLY A FEW TORNADOES.
   
   FARTHER S...A FEW SEVERE STORMS SHOULD ALSO DEVELOP DURING THE
   AFTERNOON/EVENING NEAR THE SURFACE COLD FRONT FROM ERN OK INTO MO. 
   INSTABILITY AND VERTICAL SHEAR WILL ALSO BE FAVORABLE FOR SUPERCELLS
   THIS AREA...ESPECIALLY DURING THE EVENING WHEN LOW-LEVEL SHEAR IS
   FORECAST TO STRENGTHEN WITHIN THE WARM SECTOR. ACTIVITY ALONG THE
   FRONT WILL SPREAD EWD OVERNIGHT...WITH THE SEVERE THREAT LIKELY TO
   GRADUALLY DECREASE AS INSTABILITY DIMINISHES.
