..NO SEVERE THUNDERSTORM AREAS FORECAST
 
 
   
..SUMMARY
 
 
SEVERE THUNDERSTORMS ARE NOT EXPECTED ACROSS THE CONTIGUOUS UNITED  
STATES THURSDAY.  
   
..DISCUSSION
 
 
A CLOSED MID/UPPER LOW OFFSHORE THE PACIFIC NORTHWEST COAST WILL  
GRADUALLY OPEN AND MOVE ASHORE THROUGH THE PERIOD AS A BROAD TROUGH.  
TO ITS SOUTH, A STRONG WESTERLY JET OVER NORTHERN CALIFORNIA AND THE  
GREAT BASIN WILL FAVOR DOWNSTREAM DE-AMPLIFICATION OF A RIDGE OVER  
THE NORTHERN PLAINS. MEANWHILE, STRONG CYCLONIC FLOW WILL FURTHER  
OVERSPREAD THE GREAT LAKES AND NORTHEAST, BRINGING A VERY COLD AIR  
MASS TO THE REGION.  
 
A FEW THUNDERSTORMS WILL BE POSSIBLE NEAR THE SOUTHEAST COAST,  
GENERALLY ROOTED ABOVE A SURFACE STABLE LAYER NORTH OF A FRONT.  
ADDITIONALLY, AS TEMPERATURES COOL ALOFT ACROSS THE PACIFIC  
NORTHWEST, WEAK BUOYANCY MAY FOSTER ISOLATED THUNDERSTORMS OVER  
PARTS OF THE REGION THROUGH THE PERIOD. IN BOTH CASES, SEVERE  
WEATHER IS NOT CURRENTLY ANTICIPATED.
