...DISCUSSION...
SVR THUNDERSTORMS WILL BE UNLIKELY FOR D4/SUN THROUGH D8/THU.
MEDIUM-RANGE MODEL GUIDANCE INDICATES LITTLE OPPORTUNITY FOR ANY
SUBSTANTIAL POLEWARD FLUXES OF APPRECIABLE MOISTURE AND ENSUING
INLAND BUOYANCY WHILE A MULTI-STREAM MID-LEVEL FLOW PATTERN PREVAILS
THROUGH MOST OF THE PERIOD. THERE IS SOME POTENTIAL FOR
AMPLIFICATION OF A TROUGH OVER PORTIONS OF THE CNTRL/ERN UNITED
STATES FOR THE MIDDLE OF NEXT WEEK. HOWEVER...LARGE VARIABILITY
AMONGST MODEL SOLUTIONS REGARDING THE EVOLUTION OF SUCH A FEATURE
AND ITS RELATED PROPENSITY TO SUPPORT ANY SVR THUNDERSTORM POTENTIAL
ACROSS THE GULF COAST REGION EXIST. FURTHERMORE...MANY SOLUTIONS
INDICATE LITTLE...IF ANY...PHASING OF APPRECIABLE BUOYANCY WITH
TROUGH-PRECEDING ASCENT...THUS MITIGATING THE OVERALL SVR
THUNDERSTORM RISK.
