Area forecast discussion, Jul 3, 2:57 PM CDT, 43 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
257 PM CDT TUE JUL 3 2012

.SHORT TERM...TONIGHT THROUGH FRIDAY.

DIURNAL CONVECTION STARTED ACROSS AREAS SOUTH OF I-20 AS EXPECTED.
GOOD MIXING OF THE AIR MASS IN THE LOW LEVELS HAS BROUGHT SURFACE
DEWPOINTS DOWN INTO THE 50S ACROSS AREAS NORTH OF BIRMINGHAM. AREAS
NORTH OF I-20 HAVE VERY LITTLE CUMULUS DEVELOPMENT...AND REMOVED
RAIN CHANCES FOR NORTHWEST COUNTIES FOR THE REMAINDER OF THE
AFTERNOON. CONVECTION ACROSS THE SOUTH WILL DIMINISH AFTER SUNSET
AND SHOULD BE MOSTLY GONE BY 9 PM.

THE WEATHER ON THE FOURTH OF JULY SHOULD BE SIMILAR TO TODAY. MOS
GUIDANCE HAS BEEN UNDER-FORECASTING HIGH TEMPERATURES DURING THIS
HEAT WAVE AND WENT ABOVE MOS NUMBERS FOR WEDNESDAY. EVEN WITH
TEMPERATURES APPROACHING 100 IN SOME AREAS...HEAT INDICES WILL
LIKELY STAY BELOW 105 DEGREES...AND WILL NOT EXTEND THE HEAT
ADVISORY AT THIS TIME. THE NAM MODEL...WHICH HAS DONE FAIRLY
WELL FORECASTING LOW LEVEL THICKNESS VALUES...IS ALSO INDICATING
LOWER THICKNESS VALUES ON WEDNESDAY COMPARED TO TODAY. HIGH
PRESSURE CENTER TO THE NORTHWEST OF ALABAMA WILL PRODUCE MORE
SUBSIDENCE OVER NORTH ALABAMA THE NEXT FEW DAYS...AND BETTER RAIN
CHANCES WILL CONTINUE FOR AREAS SOUTH OF I-20.

.LONG TERM...SATURDAY THROUGH TUESDAY.

BY SATURDAY THE UPPER HIGH CENTERED OVER THE MIDWEST STATES WILL
EXPAND EASTWARD AND BECOME ELONGATED IN AN EAST-WEST DIRECTION.
CENTRAL ALABAMA WILL STAY SOUTH OF THE RIDGE AXIS AND THIS WILL
ALLOW FOR SCATTERED THUNDERSTORMS TO DEVELOP EACH DAY...AND
CONTINUED LOW END CHANCE POPS THROUGH EARLY NEXT WEEK. ALL THE
MODELS ARE FORECASTING A DIGGING UPPER TROF ALONG THE ATLANTIC
COAST EARLY NEXT WEEK. THE GFS IS THE MOST AGGRESSIVE WITH DIGGING
TROF AND PUSHES A SURFACE FRONT INTO NORTH ALABAMA ON TUESDAY.
THE MAIN IMPACT OF THIS CHANGE IN THE UPPER HEIGHT PATTERN IS THAT
IT SHOULD RESULT IN SLIGHTLY COOLER TEMPERATURES AND CONTINUED
CHANCES FOR RAIN.

58/ROSE

.AVIATION...
18Z TAF DISCUSSION.

MOSTLY VFR CONDITIONS FOR ALL SITES.  THE ONLY THING TO WATCH FOR
THIS AFTERNOON WILL BE A VCTS AT KANB KMGM AND KTOI.  ANY SITE THAT
SEES A TS OVERHEAD WILL LIKELY SEE A SHORT REDUCTION IN CIGS/VIS.
TONIGHT THESE SAME SITE WILL HAVE TO WATCH FOR REDUCED VIS AFTER
MIDNIGHT AS THE LOW LEVEL MOISTURE WILL HELP TO PRODUCE MVFR FOG.
WINDS WILL GENERALLY BE LIGHT AND OUT OF THE NORTHWEST.
