..SUMMARY
 
 
LITTLE IF ANY THUNDERSTORMS ARE EXPECTED ACROSS THE USA ON SUNDAY.  
   
..SYNOPSIS
 
 
AN UPPER LOW WILL REMAIN OVER THE CANADIAN MARITIMES FOR MUCH OF THE  
DAY SUNDAY, AND WILL SHIFT EAST OVERNIGHT AS UPPER RIDGING OCCURS  
OVER THE MIDWEST AND LOWER GREAT LAKES. TO THE WEST, HEIGHT FALLS  
WILL SPREAD EAST ACROSS MUCH OF THE WEST DURING THE DAY AND INTO THE  
PLAINS OVERNIGHT, WITH A LEAD TROUGH EXTENDING FROM MANITOBA INTO  
THE NORTHERN AND CENTRAL PLAINS BY 12Z MONDAY.  
 
AT THE SURFACE, HIGH PRESSURE WILL REMAIN OVER THE SOUTHEAST, WITH A  
TROUGH DEVELOPING FROM THE UPPER MS VALLEY SOUTHWESTWARD TO THE  
SOUTHERN HIGH PLAINS 00Z. SOUTHERLY WINDS WILL INCREASE OVER THE  
WESTERN GULF OF MEXICO, WITH INCREASING SURFACE TO 850 MB  
SOUTHWESTERLIES AIDING LOW-LEVEL MOISTURE TRANSPORT.  
 
WHILE THE AIR MASS FROM EASTERN TX INTO THE LOWER MS VALLEY WILL  
CONTINUALLY MOISTEN, LAPSE RATES WILL REMAIN POOR, AND THEREFORE,  
THUNDERSTORMS ARE NOT FORECAST IN THIS REGION.  
 
ELSEWHERE, VERY WEAK INSTABILITY MAY AGAIN DEVELOP NEAR THE SHORES  
OF WA AND OR, BUT THE BULK OF ANY LOW-TOPPED THUNDERSTORMS ARE  
EXPECTED TO REMAIN OFFSHORE.
