DAY 2 CONVECTIVE OUTLOOK  
NWS STORM PREDICTION CENTER NORMAN OK  
1059 AM CST MON NOV 06 2017  
 
VALID 071200Z - 081200Z  
   
..NO SEVERE THUNDERSTORM AREAS FORECAST
 
 
   
..SUMMARY
 
 
THE THREAT OF SEVERE STORMS APPEARS LOW ACROSS THE CONTIGUOUS UNITED  
STATES ON TUESDAY.  
   
..SOUTHEAST
 
 
FAST, ZONAL MID/UPPER FLOW WILL PERSIST FROM THE DESERT SOUTHWEST TO  
THE EAST COAST TUESDAY. AS A COMPACT VORTICITY MAX DROPS SOUTHEAST  
FROM THE GREAT BASIN TOWARDS THE FOUR CORNERS, SEVERAL WEAK/SHEARED  
IMPULSES EMBEDDED IN FAST SOUTHERN STREAM FLOW WILL ADVANCE FROM THE  
LOWER/MID MISSISSIPPI VALLEY TOWARDS THE SOUTHEAST AND MID-ATLANTIC.  
 
AT THE SURFACE, HIGH PRESSURE WILL BUILD OVER THE PLAINS, PUSHING A  
COLD FRONT SOUTHEAST TOWARDS THE GULF COAST. MEANWHILE, A WEAK  
CYCLONE WILL EVOLVE OVER THE SOUTHERN APPALACHIANS THROUGH THE DAY,  
WITH THE AFOREMENTIONED COLD FRONT TRAILING TO ITS SOUTHWEST. STORMS  
WILL LIKELY BE ONGOING DURING THE MORNING, WITHIN A WARM-ADVECTION  
REGIME OVER THE CAROLINAS AND SOUTHERN MID-ATLANTIC. LATER IN THE  
DAY, ISOLATED STORMS MAY DEVELOP NEAR THE FRONT TO THE SOUTHWEST OF  
THE CYCLONE. EFFECTIVE SHEAR AND MODEST BUOYANCY COULD SUPPORT A  
STRONGER CORE OR TWO, WITH PERHAPS SOME HAIL/GUSTY WIND THREAT.  
HOWEVER, VEERED/WEAK LOW-LEVEL FLOW AND RELATED WEAK CONVERGENCE  
SHOULD KEEP COVERAGE RELATIVELY LOW, WITH MOST UPDRAFTS STRUGGLING  
TO DEEPEN SUFFICIENTLY FOR A GREATER THREAT. AS SUCH, NO SEVERE  
PROBABILITIES ARE INTRODUCED AT THIS TIME.
