AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
626 AM CDT SUN MAY 19 2013

.UPDATE...
FOR 12Z AVIATION.

&&

.DISCUSSION...

CALMER CONDITIONS ACROSS CENTRAL ALABAMA THIS MORNING ARE
WELCOMED AFTER FLOODING AFFECTED EASTERN LOCATIONS YESTERDAY...RESULTING
IN ELEVATED STREAM LEVELS AND SEVERAL RIVERS AT CAUTION OR FLOOD
STAGE. SEE THE LATEST RIVER FORECAST PRODUCTS FOR SPECIFICS. MOST
OF THE AREA SHOULD REMAIN DRY TODAY...EXPECT THE EAST WHERE
RAINFALL IS NOT NEEDED. THE SLOW MOVING PATTERN WILL SHIFT FAR
ENOUGH EAST TONIGHT BRINGING DRY CONDITIONS BACK TO THE AREA FOR
AT LEAST THE FIRST HALF OF THE WORK WEEK.

THIS MORNING...A SLOW MOVING MID LEVEL TROUGH IS LOCATED JUST TO
OUR NORTHEAST AND PROVIDING LIFT FOR A COMPLEX OF STORMS MOVING
SOUTHEASTWARD ACROSS CENTRAL GEORGIA. THE APPROACHING MID LEVEL
RIDGE AXIS THAT WILL FINALLY PUSH THIS TROUGH AWAY FROM THE AREA
STRETCHES NORTHWARD ALONG THE MISSISSIPPI RIVER. CIRRUS FROM A MCS
ROTATING AROUND THE EDGE OF THE RIDGE AXIS IN OK AND KS IS
SPREADING EASTWARD ACROSS THE AREA. ISOLATED CONVECTION THAT WAS
ONGOING EARLIER TONIGHT ACROSS CENTRAL ALABAMA HAS DISSIPATED.

MODELS CONTINUE TO SHOW REDEVELOPMENT TODAY...PARTICULARLY IN THE
FAR EAST...WHERE FORCING FROM THE NEARBY TROUGH WILL HELP SPARK
SHOWERS AND THUNDERSTORMS. AS THE MID LEVEL RIDGE BUILDS TOWARD
THE AREA...EXPECT ACTIVITY TO SHIFT EASTWARD AS A WHOLE THROUGH
THE DAY. PWS REMAIN OVER 1.5 INCHES...AND HEAVY RAINFALL WILL BE
THE PRIMARY CONCERN WITH ANY CONVECTION. CONDITIONS WILL NEED TO
BE MONITORED CLOSELY AS ANY RAINFALL COULD COMPLICATE FLOOD PROBLEMS.
WILL NOT CARRY ANY POPS OVERNIGHT TONIGHT AS ALL ACTIVITY SHOULD
BE TO THE EAST. GIVEN THE MOIST GROUND CONDITIONS...ADDED PATCHY
FOG TO THE FORECAST. BOUNDARY LAYER WINDS REMAIN ELEVATED AND DO
NOT ANTICIPATE ANY DENSE FOG PROBLEMS AT THIS POINT.

WITH THE RIDGE AXIS CROSSING THE SOUTHEASTERN CONUS THROUGH THE FIRST
HALF OF THE WORK WEEK...CONDITIONS WILL BE DRY. DEWPOINTS
WILL REMAIN IN THE 60S AND HIGHS AROUND 90. THE NEXT SYSTEM TO
AFFECT CENTRAL ALABAMA WILL COME FROM THE LONGWAVE TROUGH
CURRENTLY SITTING OVER THE WESTERN CONUS. AS THIS SYSTEM SHIFTS
ACROSS THE PLAINS AND INTO THE MIDWEST...A FRONT WILL MOVE THROUGH
THE AREA DURING THE WEDNESDAY/THURSDAY TIME FRAME. MOST OF THE FORCING
REMAINS NORTH OF THE AREA...CLOSER TO THE PARENT SURFACE LOW CROSSING
THE MIDWEST. WIND SHEAR AND INSTABILITIES ARE NOT IMPRESSIVE...AND
WILL MAINTAIN ONLY CHANCE POPS AND NO MENTION OF SEVERE IN THE
HWO.

MODEL SOLUTIONS DIFFER TOWARD THE END OF THE WEEK IN REGARDS TO
HOW QUICKLY MID LEVEL RIDGING BUILDS ACROSS THE SOUTHEAST. WILL
FAVOR THE DRIER AND MORE PROGRESSIVE ECMWF FOR NOW...WITH SLIGHTLY
COOLER AND DRIER CONDITIONS FOR NEXT WEEKEND.

.AVIATION...
12Z TAF DISCUSSION.

WIDESPREAD IFR CIGS WILL SLOWLY RISE THIS MORNING GIVING WAY TO
VFR CONDITIONS BY LATE MORNING/EARLY AFTERNOON. ISO/SCT CONVECTION
EXPECTED AGAIN TODAY MAINLY IN THE EAST. WINDS WILL BE OUT OF THE
SSW TODAY AT 5-10 KTS. PATCHY FOG IS POSSIBLE AFTER MIDNIGHT DUE
TO MOIST GROUND CONDITIONS COMBINED WITH LIGHT/CALM SFC WINDS.
