AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW ORLEANS/BATON ROUGE LA 
220 PM CST TUE NOV 12 2002

A WELL DESERVED PERIOD OF QUIET AND DRY WEATHER IS IN STORE FOR THE 
FORECAST AREA AS AN AMPLIFYING UPPER TROUGH SHIFTS EAST OF THE 
LOWER MISSISSIPPI VALLEY TO THE EAST COAST WHILE WEAK UPPER LEVEL 
RIDGING PREVAILS ACROSS THE CENTRAL GULF COAST AND LOWER MISSISSIPPI 
VALLEY REGION THROUGH THE MIDDLE OF THE WEEK. THE NEXT FORECAST 
PROBLEM WILL OCCUR AT THE END OF THE WEEK AS AN INITIALLY BROAD 
UPPER TROUGH DEVELOPS ACROSS MUCH OF THE CENTRAL AND EASTERN U.S. 
AND THEN AMPLIFIES SIGNIFICANTLY AS IT MOVES ACROSS THE EASTERN 
CONUS WITH THE POSSIBLE DEVELOPMENT OF AN UPPER LOW ACROSS THE 
SOUTHEAST STATES. THIS FEATURE WILL PUSH ANOTHER COLD FRONT ACROSS 
THE FORECAST AREA FRIDAY AND FRIDAY EVENING BRINGING A CHANCE OF 
SHOWERS FRIDAY THAT WILL LINGER INTO SATURDAY AS THE UPPER LEVEL 
SYSTEM TRAVERSES THE AREA. THIS SYSTEM WILL PULL MUCH COLDER AIR 
SOUTH TO THE GULF COAST WITH LOWS IN THE 30S EXPECTED ACROSS SOUTH 
MISSISSIPPI AND AREAS OF SOUTHEAST LOUISIANA NORTH AND NORTHWEST OF 
LAKE PONTCHARTRAIN OVER THE WEEKEND. TEMPERATURES WILL BEGIN TO 
MODERATE EARLY NEXT WORK WEEK.
