..DISCUSSION
 
 
MEDIUM-RANGE MODELS REMAIN IN RELATIVELY GOOD LARGE-SCALE AGREEMENT  
THROUGH THE PERIOD, WITH A GENERALLY ZONAL/WESTERLY FLOW PATTERN  
INTERRUPTED PERIODICALLY BY LOW-AMPLITUDE WAVES PROGRESSING ACROSS  
THE CONUS.  
 
WITH THESE WAVES BEING OF THE LOW-AMPLITUDE VARIETY, AND GIVEN  
SUBSTANTIAL INTRUSION OF A COOL/DRY/STABLE AIRMASS INTO THE CENTRAL  
AND EASTERN STATES, PROSPECTS FOR APPRECIABLE  
MOISTENING/DESTABILIZATION AHEAD OF THESE TROUGHS APPEARS  
NEGLIGIBLE, FOLLOWED IN EACH CASE BY RE-INTRUSION OF CONTINENTAL  
POLAR AIR. THEREFORE, POTENTIAL FOR SEVERE WEATHER APPEARS LIKELY  
TO REMAIN LOW ACROSS THE U.S. THROUGH THE PERIOD.
