...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS NORTH-CENTRAL INTO  
EASTERN NEBRASKA...  
   
..SUMMARY
 
 
WIDELY SCATTERED SEVERE THUNDERSTORMS ARE POSSIBLE FRIDAY AFTERNOON  
THROUGH THE EVENING ACROSS PARTS OF NEBRASKA. SEVERE GUSTS AND  
LARGE HAIL ARE THE PRIMARY RISKS WITH THE STRONGER STORMS.  
   
..CENTRAL PLAINS/LOWER TO MID MISSOURI VALLEY
 
 
AN MCV/CONVECTIVELY MODULATED MID-LEVEL DISTURBANCE, EVIDENT ON  
SATELLITE IMAGERY THURSDAY MORNING OVER WY, IS FORECAST TO CREST A  
MID-LEVEL RIDGE AND MOVE SOUTHEAST ACROSS THE NORTH-CENTRAL GREAT  
PLAINS AND INTO THE CORNBELT BY FRIDAY NIGHT. A QUASI-STATIONARY  
FRONT WILL BE DRAPED FROM NEAR THE NE/SD BORDER SOUTHEASTWARD INTO  
MO. IT IS NEAR THIS BOUNDARY WHERE THE FOCUS FOR CONVECTIVE  
DEVELOPMENT IS EXPECTED DURING THE PERIOD. A MOIST TO VERY MOIST  
BOUNDARY LAYER AND STRONG HEATING WILL RESULT IN AMPLE BUOYANCY BY  
PEAK HEATING. VEERING FLOW WITH HEIGHT WILL RESULT IN A WIND  
PROFILE SUPPORTING ORGANIZED STORMS. A CLUSTER OF STORMS WILL  
PROBABLY DEVELOP DURING THE AFTERNOON AND MOVE SOUTHEAST ACROSS  
PARTS OF NE DURING THE EARLY EVENING. HAIL/WIND WILL BE THE PRIMARY  
THREATS WITH THE STRONGER STORMS.  
   
..CAROLINAS
 
 
A MID-LEVEL TROUGH WILL MOVE EAST INTO THE ATLANTIC FROM THE  
NORTHEAST U.S. AND NORTHWESTERLY FLOW WILL WEAKEN WITH SOUTHWARD  
EXTENT INTO THE SOUTHEAST STATES. A COLD FRONT WILL PUSH SOUTHWARD  
INTO THE CAROLINAS AND FOCUS SHOWER/STORM DEVELOPMENT MAINLY DURING  
THE EARLY AFTERNOON TO EARLY EVENING PERIOD. THE FORECAST WIND  
PROFILE WILL FAVOR RELATIVELY SLOW MOVING MULTICELLS WITHIN A  
MOIST/MODERATELY UNSTABLE ENVIRONMENT. A FEW STORMS MAY BE CAPABLE  
OF STRONG TO PERHAPS LOCALLY SEVERE GUSTS (45-60 MPH) BEFORE THIS  
ACTIVITY WEAKENS BY THE EARLY EVENING.
