..DISCUSSION
 
 
EXPANSIVE UPPER RIDGING IS EXPECTED TO BE IN PLACE ACROSS MUCH OF  
WESTERN NORTH AMERICA ON D4/WEDNESDAY, WITH THIS RIDGING EXPECTED TO  
PERSIST THROUGH THE WEEKEND. UPPER TROUGHING WILL LIKELY EXTEND FROM  
NORTHERN QUEBEC THROUGH ONTARIO, THE UPPER GREAT LAKES, AND THE MID  
MS VALLEY EARLY D4/WEDNESDAY. PRIMARY PORTION OF THIS UPPER TROUGH  
IS FORECAST TO GRADUALLY SHIFT EASTWARD ACROSS THE REMAINDER OF  
ONTARIO AND THE UPPER GREAT LAKES ON D4/WEDNESDAY AND THE NORTHEAST  
ON D5/THURSDAY, BUT MODEST UPPER TROUGHING IS EXPECTED TO REMAIN IN  
PLACE OVER MUCH OF THE EASTERN CONUS INTO THE WEEKEND.  
 
AT THE SAME TIME, A COLD FRONT WILL GRADUALLY PUSH  
SOUTHWARD/SOUTHEASTWARD ACROSS THE CENTRAL PLAINS, OH VALLEY, AND  
NORTHEAST ON D4/WEDNESDAY AND NORTHERN PART OF THE SOUTHERN PLAINS,  
MID-SOUTH, AND TN VALLEY ON D5/THURSDAY. SOME LIMITED SEVERE  
POTENTIAL MAY EXIST ACROSS THE NORTHEAST ON D4/WEDNESDAY BEFORE THE  
FRONT CLEARS THE REGION. AFTER D4/WEDNESDAY, PROGRESSION OF THE  
FRONT WILL DISPLACE THE BETTER LOW-LEVEL MOISTURE SOUTH OF THE  
STRONGER FLOW ALOFT, LIMITING THE SEVERE-STORM POTENTIAL ACROSS MUCH  
OF THE CENTRAL AND EASTERN CONUS THROUGH THE WEEKEND. THE ONLY  
EXCEPTION IS ACROSS THE HIGH PLAINS, WHERE MODEST LOW-LEVEL MOISTURE  
BENEATH VERTICALLY VEERING WIND PROFILES COULD SUPPORT A FEW STRONG  
TO SEVERE STORMS EACH AFTERNOON.
