..NO SEVERE THUNDERSTORM AREAS FORECAST
 
 
   
..SUMMARY
 
 
ISOLATED THUNDERSTORMS WILL BE POSSIBLE ON SATURDAY OVER PORTIONS OF  
THE SOUTHEAST, AND NEAR THE NORTHERN CALIFORNIA COAST.  
   
..DISCUSSION
 
 
FAST/GENERALLY WESTERLY FLOW ALOFT IS EXPECTED ACROSS MOST OF THE  
U.S. ON SATURDAY, WITH A TIGHT HEIGHT GRADIENT BETWEEN RIDGING OVER  
THE GULF OF MEXICO, AND A POLAR TROUGH ACROSS CENTRAL AND EASTERN  
CANADA AND THE GREAT LAKES REGION. A SHORT-WAVE TROUGH, EMBEDDED IN  
THIS FAST FLOW FIELD, WILL SWEEP ACROSS THE NORTHEASTERN U.S.  
THROUGH THE PERIOD. FARTHER WEST, A LOW IS FORECAST TO LINGER JUST  
OFF THE OREGON/NORTHERN CALIFORNIA COASTAL AREA THROUGH THE PERIOD.  
 
AT THE SURFACE, A COLD FRONT SHOULD STRETCH FROM A JAMES BAY LOW  
SOUTHWARD TO LAKE ERIE AND THEN SOUTHWESTWARD INTO TEXAS AT THE  
START OF THE PERIOD. THIS FRONT WILL MOVE QUICKLY EASTWARD,  
CLEARING THE EASTERN SEABOARD BY EARLY EVENING, WHILE MOVING MORE  
SLOWLY SOUTHWARD ACROSS FLORIDA AND THE GULF OF MEXICO THROUGH EARLY  
SUNDAY. HIGH PRESSURE WILL PREVAIL ACROSS MOST OF THE COUNTRY, IN  
THE WAKE OF THIS FRONT.  
 
SHOWERS -- AND A FEW/EMBEDDED THUNDERSTORMS -- WILL LIKELY ACCOMPANY  
THE PASSAGE OF THIS FRONT ACROSS THE EAST COAST AND SOUTHEAST  
STATES. SHOWERS AND POSSIBLY A FEW LIGHTNING FLASHES WILL ALSO  
ACCOMPANY THE EASTERN PACIFIC LOW, POSSIBLY SPREADING INTO COASTAL  
AREAS OF NORTHERN CALIFORNIA AND OREGON, PARTICULARLY LATER IN THE  
PERIOD.
