..DISCUSSION
 
 
MEDIUM-RANGE GUIDANCE IS IN REASONABLE AGREEMENT THAT UPPER RIDGING  
WEST OF THE ROCKIES WILL PERSIST INTO NEXT WEEKEND WHILE A SERIES OF  
SHORTWAVE TROUGHS CONTRIBUTE TO BROAD UPPER TROUGHING ACROSS THE  
CENTRAL AND EASTERN CONUS. THIS WILL RESULT IN GENERALLY  
ABOVE-AVERAGE TEMPERATURES ALONG AND WEST OF THE ROCKIES WHILE  
BELOW-AVERAGE TEMPERATURES EXIST ELSEWHERE. THERE IS SOME POTENTIAL  
FOR A COLD FRONT RESULTING FROM ONE OF THE SHORTWAVE TROUGHS TO  
INTERACT WITH A MODERATELY MOIST AND UNSTABLE AIRMASS SUPPORTIVE OF  
STRONG THUNDERSTORMS. HOWEVER, LOW CONSISTENCY WITHIN THE GUIDANCE  
CURRENTLY PRECLUDES MUCH CONFIDENCE IN THAT SCENARIO.
