AREA FORECAST DISCUSSION

414 AM CST SAT FEB 1 2003

NOT MUCH TIME TO TALK AS I HAVE TO GO BACK AND MAKE NUMEROUS
CORRECTIONS TO THE GRIDDED DATABASE. BRIEFLY...RIDGE MOVES EAST OF
THE AREA TODAY ALLOWING THE START OF WAA TO OCCUR. VERY MOIST
BOUNDARY LAYER SHOULD RESULT IN CONSIDERABLE CLOUD COVER TODAY.
TONIGHT COLD/DAMP GROUND COMBINED WITH WAA...A SATURATED BOUNDARY
LAYER...AND WEAK SURFACE CONVERGENCE SHOULD RESULT IN ADVECTION FOG
DEVELOPMENT. FOG SHOULD BURN OFF IN MOST AREAS SUNDAY MORNING.
POSSIBILITY EXISTS FOR HEADLINES FOR FOG BUT WILL LET DAY SHIFT
DECIDE THIS.

LIKE THE NGM IDEA OF BRINGING THE WARM FRONT INTO THE FAR SOUTH
CWFA ON SUNDAY. THIS TIME OF YEAR THE WARM FRONT USUALLY DOES GET TO
AROUND KEOK OR JUST A LITTLE FURTHER NORTH. ALSO 06Z META IS NOW
FURTHER NORTH WITH WARM FRONT COMPARED TO 00Z RUN. ISENTROPIC LIFT
AND WAA SHOULD ALLOW PRECIP TO BREAK OUT DURING THE AFTERNOON AS WEAK
SHORTWAVE MOVES THROUGH. SUNDAY NIGHT MAIN EVENT STARTS AND CONTINUES
INTO MONDAY. PRECIP TO START OUT AS RAIN AND CHANGE OVER DURING THE
DAY MONDAY.

NO CHANGES TO EXTENDED ATTM.

.DVN...
IA...NONE.
IL...NONE.
MO...NONE.
