AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
230 PM CST FRI NOV 27 2009

.DISCUSSION...
HIGH PRESSURE HAS SHIFTED TO THE SOUTHEAST WHICH HAS ALLOWED FOR
SURFACE WINDS ACROSS THE AREA TO SWITCH AROUND TO THE SOUTHWEST. THIS
WILL ALLOW FOR A VERY SLOW MODERATION OF THE ATMOSPHERE OUT AHEAD
OF ANOTHER SYSTEM THAT WILL MOVE INTO THE FOUR STATE REGION LATE
SUNDAY. INSTABILITY WILL BE LACKING OUT AHEAD OF THE COLD FRONT
FOR MUCH OF THE AREA EXCEPT FOR SOME OF OUR EXTREME SOUTHERN
AREAS. THE MODELS ARE STILL SHOWING AN AVERAGE OF 1 TO 2 INCHES OF
QPF FOR THE AREA...AND THIS SEEMS TO BE THE MAJOR CONCERN WITH THE
SYSTEM. 

FOR THE EXTENDED...MODEL INCONSISTENCIES ARE INHIBITING ANY REAL
HANDLE ON TEMPERATURES LATE IN THE PERIOD.

.AVIATION...

VFR CONDITIONS WILL PREVAIL THROUGHOUT THE NIGHT INTO MUCH OF THE 
DAY SATURDAY. HIGH CLOUDS WILL CONTINUE TO INCREASE FROM THE SOUTH 
THROUGH THE NIGHT INTO THE DAY SATURDAY AS WELL. PRESSURE GRADIENT
