..SUMMARY
 
 
ISOLATED THUNDERSTORMS ARE EXPECTED ACROSS THE SOUTHERN FLORIDA  
PENINSULA ON MONDAY.  
   
..SYNOPSIS
 
 
A MEAN UPPER TROUGH WILL PERSIST ACROSS THE EASTERN U.S. ON MONDAY  
WHILE AN UPPER RIDGE BUILDS ACROSS THE WESTERN HALF OF THE COUNTRY.  
WITHIN THE WESTERN UPPER RIDGE, AN UPPER LOW OVER SOUTHERN CA WILL  
BECOME CUT-OFF AND SHIFT SOUTHWEST OVER THE PACIFIC OFFSHORE FROM  
SOUTHERN CA/NORTHERN BAJA. AT THE SURFACE, HIGH PRESSURE WILL  
ENVELOP MUCH OF THE CONUS, BRINGING DRY AND STABLE CONDITIONS WITH  
LITTLE CHANCE OF THUNDERSTORM ACTIVITY. THE EXCEPTION WILL BE ACROSS  
THE SOUTHERN FLORIDA PENINSULA, MAINLY DURING THE MORNING HOURS. A  
WEAK SURFACE LOW OFFSHORE THE SOUTHWEST FL COAST WILL QUICKLY SHIFT  
EAST/NORTHEAST BY EARLY AFTERNOON, AND A COLD FRONT WILL SAG  
SOUTHWARD. WEAK INSTABILITY AND POOR LAPSE RATES SHOULD LIMIT SEVERE  
POTENTIAL, THOUGH STRONG SOUTHWESTERLY DEEP LAYER FLOW WILL PERSIST  
THROUGH AT LEAST MIDDAY. THIS COULD RESULT IN A BRIEFLY ORGANIZED  
STORM OR TWO, CAPABLE OF GUSTY WINDS.
