   VALID 202059Z - 202200Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 523 CONTINUES.
   
   PARTICULARLY DANGEROUS SITUATION TORNADO WATCH 523 CONTINUES UNTIL
   01Z WITH A CONTINUED THREAT OF TORNADOES AND LARGE HAIL ESPECIALLY
   ACROSS SOUTH-CENTRAL/EAST-CENTRAL NEB INCLUDING THE I-80
   CORRIDOR/CENTRAL NEB TRI-CITIES AREA THROUGH LATE AFTERNOON.
   
   LATEST SUBJECTIVE SURFACE ANALYSIS CONTINUES TO REFLECT A
   NORTH-NORTHEASTWARD SHIFTING SURFACE LOW /AROUND 992 MB/ NOW LOCATED
   NEAR THE SOUTH-CENTRAL NEB/NORTH-CENTRAL KS BORDER. ON THE PERIPHERY
   OF THE SURFACE LOW...A WARM FRONT CONTINUES TO LIFT NORTHWARD ACROSS
   EASTERN NEB...WITH A SURFACE FRONT/FRONTAL BOUNDARY EXTENDING
   NORTHWARD FROM THE SURFACE LOW ACROSS CENTRAL NEB. THIS LATTER
   SSW-NNE ORIENTED BOUNDARY AND THE AREA ON THE IMMEDIATE NORTH SIDE
   OF THE SURFACE LOW WILL REMAIN HIGHLY FAVORABLE FOR TORNADOES
   INCLUDING THE I-80 CORRIDOR NEAR/EAST OF LEXINGTON TO KEARNEY TO
   GRAND ISLAND. HERE...RICH BOUNDARY LAYER MOISTURE CONTINUES TO WRAP
   WESTWARD NEAR/NORTH OF THE LOW AMID A HIGHLY SHEARED ENVIRONMENT.
   WITH TOWERING CU ALSO NOW NOTED NORTHEAST OF THE SURFACE LOW/NEAR
   THE WARM FRONT...EXPECT ADDITIONAL DEEP CONVECTIVE/SUPERCELLULAR
   DEVELOPMENT TO OCCUR FARTHER EAST ALONG THE I-80 GENERAL
   VICINITY/TRI-CITIES EAST-NORTHEASTWARD INTO EAST-CENTRAL NEB WHERE A
   VERY VOLATILE/WEAKLY INHIBITED BOUNDARY LAYER NOW EXISTS WITH 4000
   J/KG OF MLCAPE.
