AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
1250 PM CDT FRI MAR 30 2012

.UPDATE...AVIATION DISCUSSION.

&&

.DISCUSSION...SHOWERS AND THUNDERSTORMS THIS MORNING HAVE BEEN
CONFINED TO AREAS MAINLY WEST OF ALABAMA. IMPRESSIVE MCV OVER
CENTRAL MISSISSIPPI WILL TRACK NORTHEAST TODAY AND PRODUCE
NUMEROUS SHOWERS AND THUNDERSTORMS ACROSS CENTRAL ALABAMA THIS
AFTERNOON. CONVECTION OVER NE MISSISSIPPI HAS PRODUCED AN OUTFLOW
BOUNDARY WHICH IS MOVING EASTWARD INTO LAMAR AND MARION COUNTIES.
THIS BOUNDARY WILL NEED TO BE MONITORED FOR DEVELOPMENT DURING THE
NEXT FEW HOURS. MAIN CHANGE TO FORECAST FOR TODAY WAS TO DIVIDE
THE WEATHER GROUPS TO SHOW BETTER RAIN CHANCES ACROSS THE CENTRAL
AND EASTERN COUNTIES THIS AFTERNOON. STRONGER CONVECTION THIS
AFTERNOON WILL LIKELY BE CONFINED TO SOUTHERN COUNTIES WHERE
STRONGER SOUTHERLY LOW LEVEL FLOW WILL EXIST ALONG WITH HIGHER
SURFACE DEWPOINTS...AND CANNOT RULE OUT AN ISOLATED SEVERE STORM
SOUTH OF A LIVINGSTON TO MONTGOMERY LINE.

.AVIATION...
18Z TAF DISCUSSION.

SHOWERS AND THUNDERSTORMS HAVE INCREASED IN COVERAGE CONSIDERABLY
SINCE ABOUT 11 AM...AND ALL CENTRAL ALABAMA TAF LOCATIONS WILL
LIKELY HAVE OCCASIONAL PERIODS OF REDUCED VISIBILITY AND LOWERED
CEILINGS DUE TO STORMS MOVING THROUGH THIS AFTERNOON. WHILE FAIRLY
WIDESPREAD...THE ACTIVITY IS STILL RELATIVELY DISORGANIZED. AS A
RESULT...IT REMAINS TOUGH TO PINPOINT PASSAGE OF RAIN CELLS AT
INDIVIDUAL AIRPORTS WITH ANY KIND OF SPECIFICITY OR LEAD TIME. THE
MAIN IMPACT WILL BE LOWERED VISIBILITY...AT TIMES AT OR BELOW ONE
MILE IN THE STRONGEST STORMS. AFTER ABOUT 00Z...MY CONFIDENCE DROPS
OFF SUBSTANTIALLY REGARDING WHETHER OR THE RAIN WILL SUBSIDE/MOVE
ONWARD (I'M LEANING TOWARD YES)...AND WHETHER OR NOT LOW CLOUDS AND
FOG WILL DEVELOP IN ITS WAKE (AGAIN LEANING TOWARD YES).
