OVERALL A RATHER STAGNANT PATTERN AS THE UPPER RIDGE REMAINS  
ANCHORED ACROSS THE CENTRAL US. THE MAIN CORE OF THE JET STREAM IS  
EXPECTED TO REMAIN WELL NORTH OF THE REGION THROUGH THE FORECAST  
PERIOD, THUS TEMPERATURES ARE EXPECTED TO REMAIN ABOVE AVERAGE,  
ESPECIALLY AT NIGHT.  
 
MEANWHILE UNDERNEATH THE UPPER RIDGE A WEAK TROUGH IS TRAPPED AND  
PERSISTS ACROSS OUR REGION LEADING TO DIURNAL CONVECTION. CELLS THAT  
POP UP HAVE LITTLE OR NO STEERING, THUS A DUMP OF RAINFALL OR GUSTY  
WINDS ARE POSSIBLE.  
 
THE OVERALL WEATHER PATTERN CHANGES LITTLE UNTIL THE HOLIDAY WEEKEND  
AS A TROPICAL DISTURBANCE BEGINS TO TAKE SHAPE IN THE GULF. WHERE  
THIS CIRCULATION ENDS UP WILL DETERMINE WHETHER OUR RAINFALL IS  
ENHANCED FOR THE EARLY PART OF NEXT WEEK. RIGHT NOW IT'S TOO EARLY  
TO TELL OTHER THAN TO ANTICIPATE AT LEAST A CONTINUATION OF THE  
POSSIBILITY OF DIURNAL CONVECTION.
