VALID 311200Z - 051200Z

...DISCUSSION...
WEAK INSTABILITY/SHEAR REGIME WILL BE NOTED EARLY IN THE MEDIUM
RANGE PERIOD.  WITH TIME UPPER TROUGHING WILL EVOLVE ACROSS THE WRN
U.S. AND MODEST SWLY FLOW AT MID-LEVELS COULD SPREAD ACROSS THE
ROCKIES INTO THE NRN/CNTRL HIGH PLAINS REGION WHERE RETURN LOW-LEVEL
MOISTURE WOULD PROVE SUPPORTIVE OF ROBUST CONVECTION.  IF LATEST
ECWMF IS ACCURATE...SCT SEVERE THUNDERSTORMS MAY DEVELOP ACROSS
PORTIONS OF THE NRN/CNTRL HIGH PLAINS BEGINNING DAY6.  WHILE SEVERE
MAY ULTIMATELY EVOLVE ACROSS THIS REGION TUE/WED...PREDICTABILITY
REMAINS TOO LOW AND FORECAST SHEAR A BIT TOO WEAK TO DELINEATE A
SEVERE AREA THIS PERIOD.
