NWS STORM PREDICTION CENTER NORMAN OK
1125 PM CST SAT DEC 02 2006

VALID 041200Z - 051200Z

...NO TSTM AREAS FORECAST...

MODELS INDICATE THAT THE LARGE-SCALE TROUGH IN THE POLAR WESTERLIES
...EAST OF THE ROCKIES...WILL PERSIST INTO THIS FORECAST PERIOD. 
SOME LOSS OF AMPLITUDE AND EASTWARD EXPANSION ACROSS THE WESTERN
ATLANTIC IS FORECAST TO OCCUR...AS A SIGNIFICANT SHORT WAVE TROUGH
RAPIDLY LIFTS NORTHEAST OF THE NORTH ATLANTIC COAST AND CANADIAN
MARITIMES BY 12Z TUESDAY.  THE LOW-LEVEL CYCLONE ACCOMPANYING THIS
SYSTEM WILL CONTINUE TO DEEPEN...AND A TRAILING COLD FRONT IS
PROGGED TO ADVANCE SOUTH OF THE REMAINDER OF THE FLORIDA PENINSULA
AND KEYS.  SHOWERS ARE POSSIBLE WITH THE FRONTAL PASSAGE
MONDAY...BUT ALL INDICATIONS ARE THAT A LINGERING WARM MID-LEVEL
ENVIRONMENT WILL INHIBIT DEEP CONVECTIVE DEVELOPMENT...MINIMIZING
RISK FOR THUNDERSTORMS.

IN THE WAKE OF THE FRONT...A LARGE COLD SURFACE RIDGE WILL ENCOMPASS
MUCH OF THE GULF OF MEXICO...THE SOUTH CENTRAL/SOUTHEASTERN
STATES...AND ADJACENT ATLANTIC WATERS. MID-LEVEL
MOISTENING...ASSOCIATED WITH AN IMPULSE EMANATING FROM THE
SUBTROPICAL PACIFIC...MAY OCCUR ACROSS THE NORTHERN MEXICAN PLATEAU
INTO PARTS OF TEXAS.  AND...A COLD MID-LEVEL SHORT WAVE TROUGH IN
THE SOUTHERN BRANCH OF THE POLAR WESTERLIES IS PROGGED TO PROGRESS
INLAND ACROSS VANCOUVER ISLAND AND SOUTHERN BRITISH COLUMBIA. 
HOWEVER...THERMODYNAMIC PROFILES APPEAR LIKELY TO REMAIN STABLY
STRATIFIED ACROSS THESE AREAS...AND MUCH OF THE REMAINDER OF THE
NATION...PRECLUDING ANY APPRECIABLE RISK OF THUNDERSTORM ACTIVITY.
