..NO THUNDERSTORM AREAS FORECAST
 
 
   
..SUMMARY
 
 
THUNDERSTORMS ARE NOT EXPECTED THROUGH TONIGHT.  
   
..SYNOPSIS
 
 
AN AMPLIFIED PATTERN IS ESTABLISHED WITH A DEEP LOW OVER JAMES BAY,  
ATTENDANT CYCLONIC FLOW ACROSS MUCH OF THE EASTERN CONUS, AND AN  
UPSTREAM RIDGE OVER THE PACIFIC COAST. AN ASSOCIATED SURFACE COLD  
FRONT HAS MOVED ACROSS ALL BUT NORTH FL AND THE IMMEDIATE SOUTHEAST  
ATLANTIC COAST. SOME CONVECTION WILL BE POSSIBLE ALONG THIS  
BOUNDARY, THOUGH REGIONAL SOUNDINGS SUGGEST BUOYANCY WILL REMAIN TOO  
SHALLOW TO SUPPORT LIGHTNING PRODUCTION. LIKEWISE, THE THREAT FOR  
ANY LIGHTNING WITH WEAK MIDLEVEL CONVECTION ATOP THE COOL AIR MASS  
ALONG THE NORTH CENTRAL GULF COAST APPEARS NEGLIGIBLE.
