   VALID 121200Z - 131200Z

   ...NO SVR TSTM AREAS FORECAST...

   ...SYNOPSIS...
   MODELS SUGGEST THAT AMPLIFICATION OF THE UPPER FLOW MAY COMMENCE
   ONCE AGAIN SUNDAY INTO SUNDAY NIGHT ACROSS THE EASTERN PACIFIC INTO
   THE WESTERN U.S...WITH RIDGING BEGINNING TO BUILD OVER THE EASTERN
   PACIFIC INTO THE PACIFIC COAST.  EVENTUALLY DOWNSTREAM AMPLIFICATION
   WILL ENSUE...BUT CONSIDERABLE SPREAD DEVELOPS AMONG THE MODELS AND
   WITHIN THE MODEL ENSEMBLES CONCERNING THE SPLITTING REMNANTS OF A
   MORE SIGNIFICANT UPPER TROUGH THAT IS EXPECTED TO MIGRATE INLAND 
   OFF THE PACIFIC ON SATURDAY...BEFORE CONTINUING EASTWARD ACROSS THE
   ROCKIES...PLAINS AND MISSISSIPPI VALLEY DURING THIS PERIOD.  THIS
   INCLUDES THE SOUTHERN PORTION OF THE SPLIT DEVELOPING EAST OF THE
   CENTRAL AND SOUTHERN ROCKIES...AND ITS POSSIBLE INFLUENCE ON AN
   IMPULSE WITHIN A LINGERING WEAKER BELT OF WESTERLIES EXTENDING
   ACROSS NORTHERN MEXICO INTO THE GULF COAST. DESPITE THE MODEL
   VARIABILITY...ENOUGH OF SIGNAL SEEMS TO EXIST CONCERNING A SOUTHERLY
   RETURN FLOW OF MOISTURE AND FORCING FOR ASCENT TO SUPPORT AT LEAST
   LOWER THRESHOLD /10 PERCENT/ PROBABILITIES FOR A CATEGORICAL
   THUNDERSTORM OUTLOOK ACROSS PORTIONS OF THE WESTERN AND CENTRAL GULF
   COAST STATES.  HOWEVER... SEVERE WEATHER POTENTIAL STILL APPEARS
   NEGLIGIBLE AT THE PRESENT TIME.
