..DISCUSSION
 
 
A SHORTWAVE TROUGH IS FORECAST TO MOVE FROM THE MID MS VALLEY ACROSS  
THE OH VALLEY ON FRI/D4, ALONG WITH AN ATTENDANT SURFACE LOW. WHILE  
AT LEAST A LOW-END SEVERE RISK MAY EXIST, PREDICTABILITY IS  
CURRENTLY LOW GIVEN EXPECTED WIDESPREAD CLOUDS AND PRECIPITATION. TO  
THE EAST, A FEW STRONG STORMS CANNOT BE RULED OUT ACROSS PARTS OF NC  
WHERE MID 70S F DEWPOINTS WILL EXIST SUPPORTING STRONG INSTABILITY  
NEAR A DEVELOPING WARM FRONT, BUT SHEAR PROFILES WILL BE WEAK.  
 
PREDICTABILITY ISSUES INCREASE FURTHER BEYOND D4, WITH GENERALLY  
WEAK NORTHWEST FLOW ALOFT ACROSS THE PLAINS INTO THE SOUTHEAST ALONG  
WITH EPISODES OF THUNDERSTORMS THROUGHOUT THE PERIOD.
