..NO SEVERE THUNDERSTORM AREAS FORECAST
 
 
   
..SUMMARY
 
 
SEVERE THUNDERSTORMS ARE NOT EXPECTED ACROSS THE U.S. ON SATURDAY.  
   
..SYNOPSIS
 
 
INITIALLY ZONAL FLOW ALOFT OVER THE U.S. WILL GRADUALLY AMPLIFY ON  
SATURDAY, AS AN UPPER TROUGH OFF THE WESTERN CANADA COAST MOVES  
SLOWLY SOUTH WHILE EVOLVING INTO A LARGE CLOSED LOW. AS THIS  
OCCURS, DOWNSTREAM RIDGING WILL INCREASE ACROSS THE ROCKIES IN THE  
WAKE OF AN ALSO-AMPLIFYING SHORT-WAVE TROUGH MOVING OUT OF THE  
ROCKIES AND INTO/ACROSS THE NORTH-CENTRAL STATES.  
 
AT THE SURFACE, HIGH PRESSURE WILL REMAIN PREDOMINANT ACROSS THE  
COUNTRY, WITH ONLY A WEAK SURFACE REFLECTION OF THE AFOREMENTIONED  
SHORT-WAVE TROUGH CROSSING THE CENTER OF THE COUNTRY.  
 
WHILE SHOWERS ARE EXPECTED OVER PARTS OF THE WEST, THE ONLY RISK FOR  
INLAND THUNDER SHOULD REMAIN CONFINED TO THE FLORIDA VICINITY.  
HERE, EASTERLY/ONSHORE LOW-LEVEL FLOW MAY RESULT IN A COUPLE OF  
THUNDERSTORMS EVOLVING -- PARTICULARLY DURING THE AFTERNOON NEAR AN  
EAST-COAST SEA-BREEZE BOUNDARY. SEVERE WEATHER IS NOT EXPECTED.
