AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
1245 PM CDT SAT JUN 30 2012
.UPDATE...AVIATION DISCUSSION.
&&
.DISCUSSION...
THE HEAT IN ON ACROSS CENTRAL ALABAMA. TEMPERATURES ARE AVERAGING
ABOUT 2 DEGREES WARMER THAN YESTERDAY...AND AIR TEMPERATURES WILL
LIKELY REACH THE 106 DEGREE MARK IN SEVERAL LOCATIONS ACROSS THE
NORTH. FOR THE SOUTHERN COUNTIES...TEMPERATURES ARE COOLER BUT
DEWPOINTS ARE MUCH HIGHER...AND HEAT INDICES WILL MAX OUT NEAR 110
DEGREES THIS AFTERNOON. THESE FORECAST VALUES PUT MOST OF THE AREA
AT HEAT WARNING CRITERIA TODAY AND AGAIN ON SUNDAY. THE BEST
COURSE OF ACTION WAS TO UPGRADE ENTIRE AREA TO AN EXCESSIVE HEAT
WARNING THROUGH SUNDAY.
58/ROSE
&&
.AVIATION...
18Z TAF DISCUSSION.
HAZE LAYER ALOFT WILL RESTRICT VERTICAL AND HORIZONTAL FOR AIRCRAFT
LANDINGS. THE HAZE LAYER WILL SINK DOWNWARD OVERNIGHT AND PRODUCE
WIDESPREAD MVFR VSBYS IN HAZE...WITH LCL IFR VSBYS. SFC VSBYS WILL
BE LOWEST BETWEEN 10Z AND 14Z. HIGH PRESSURE RIDGE OVERHEAD WILL
PRODUCE LIGHT AND VRBL WINDS.
58/ROSE
&&
.PREV DISCUSSION... /ISSUED 715 AM CDT SAT JUN 30 2012/
TEMPERATURES EXPECTED TO BE AT LEAST AS HOT AS YESTERDAY AND
PERHAPS A DEGREE OR TWO WARMER. SUNDAY LOOKS JUST AS HOT AND WILL
EXTEND THE HEAT ADVISORY INTO SUNDAY EVENING. BEYOND
SUNDAY...LOOKS LIKE THERE WILL BE A SLIGHT UPTICK IN AVAILABLE
MOISTURE AND...FOLLOWING THE THICKNESS FORECAST...THERE IS REASON
TO BELIEVE THE EXTREME HEAT WILL BACK DOWN A FEW
DEGREES...ESPECIALLY BY THE MIDDLE OF NEXT WEEK.
CONSIDERING THE SUPPRESSING RIDGE WILL BE CENTERED VERY NEAR
CENTRAL ALABAMA TODAY...RAIN CHANCES LOOK ALMOST NIL. THE NAM AND
GFS CONTINUE WITH SOME OVERNIGHT CONVECTION BEGINNING SUNDAY NIGHT
AND STAY WITH THAT TREND THROUGH THE MODELS FORECAST PERIODS. WITH
THE INCREASE IN MOISTURE...I THINK ONE OF THINGS WE ARE SEEING
THERE IS A SLIGHTLY LOWER CONVECTIVE TEMPERATURE THAT IS REACHED
LATE IN THE AFTERNOON. WITH THESE KIND OF TEMPERATURES...ONCE A
STORM OR TWO GETS GOING IT COULD LAST FOR A WHILE INTO THE
EVENING. THE EURO AND CMC TO SOME DEGREE STAY WITH A MORE DIURNAL
LOOK...BUT REGARDLESS...THE TREND IS FOR MORE CONVECTIVE
INITIATION AS WE GET INTO THE WEEK. BY THE END OF THE WORK
WEEK...THE RIDGE RE-CENTERS TOWARDS THE MIDWEST AND CENTRAL PLAINS
LEAVING THE DEEP SOUTH IN A MORE CLIMATOLOGICAL RAINFALL SCENARIO.
ONCE WE DO START BREAKING THE AFFECTS OF THE RIDGE...ANY
THUNDERSTORMS THAT DEVELOP WILL HAVE THE POTENTIAL TO PRODUCE
DAMAGING MICROBURSTS.
