Area forecast discussion, Jul 1, 3:09 PM CDT, 59 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
309 PM CDT FRI JUL 1 2011

.DISCUSSION...

MAIN TRIGGERING MECHANISM OVER THE NEXT SEVERAL DAYS WILL BE A
VERY WEAK FRONTAL BOUNDARY. SHOWERS AND STORMS WILL DEVELOP ALONG
AND SOUTH OF THIS BOUNDARY DURING PEAK AFTERNOON HEATING AND
CONTINUING THROUGH THE EARLY EVENING HOURS. EVEN WITH LOW LEVEL
MOISTURE INCREASING THROUGH THE WEEKEND...STRONG HIGH PRESSURE
ALOFT WILL KEEP RAIN ACTIVITY FROM BECOMING MORE WIDESPREAD UNTIL
EARLY NEXT WEEK WHEN THE RIDGE BEGINS TO WEAKEN.

THE STRONG UPPER LEVEL HIGH WILL PRODUCE VERY HOT TEMPERATURES
THROUGH THE WEEKEND. SOME LOCATIONS WILL EITHER APPROACH OR HIT
TRIPLE DIGITS ON BOTH SATURDAY AND SUNDAY. AS PREVIOUSLY
MENTIONED...UPPER HIGH WILL BEGIN TO WEAKEN EARLY NEXT WEEK. THIS
WILL ALLOW TEMPERATURES TO RANGE IN THE MID 90S RATHER THAN UPPER
90S OVER MUCH OF THE AREA.

FOR THE 4TH OF JULY CELEBRATIONS...A WEAKENING UPPER HIGH WILL
ALLOW RAIN COVERAGE TO INCREASE. THIS ACTIVITY COULD LINGER INTO
THE EARLY EVENING HOURS.

FORECAST WISE...NAM12 CONTINUES TO DO THE BEST OF ALL THE MODELS
IN PICKING UP CONVECTIVE ACTIVITY AND DID NOT SEE A REASON TO
DEVIATE MUCH FROM IT. IT REMAINS THE MODEL OF CHOICE THROUGH THE
WEEKEND.

UPPER LEVEL PATTERN WILL SHIFT TO MORE OF A NORTHWEST FLOW BY THE
MIDDLE OF NEXT WEEK. THIS WILL PUT CENTRAL ALABAMA IN A MORE
FAVORABLE POSITION TO SEE A RETURN OF MESOSCALE CONVECTIVE
SYSTEMS...OR MCS.

10/ARM

&&

.AVIATION...18Z TAF DISCUSSION.

AVIATION CONCERNS WILL BE DIURNAL CONVECTION THAT WILL DEVELOP
ACROSS EAST ALABAMA.  DEEPER MOISTURE OVER EAST ALABAMA COMBINED
WITH THE PRESENCE OF A WEAK SURFACE LOW WILL COMBINE TO PRODUCE A
FAVORABLE AREA FOR AFTERNOON AND EARLY EVENING TSTM FORMATION.  THE
BEST CHANCE OF INITIAL DEVELOPMENT WILL BE BETWEEN KAUO AND KANB...
BETWEEN 19Z AND 21Z...BUT STORM FLOW FROM EAST TO WEST COULD PUSH
ANY STORMS CLOSER TO KEET AND KBHM...BY 22Z.  STORMS SHOULD DIMINISH
QUICKLY AFTER SUNSET.  LIGHT FOG COULD DEVELOP AFTER
08Z...ESPECIALLY FOR THOSE AREAS THAT EXPERIENCE RAINFALL.

NOTICE...KEET TAF WILL HAVE (AMD LTD TO VIS WIND AND WX) AMENDED TO
THE END OF THE FORECAST UNTIL FURTHER NOTICE. THE CEILOMETER DATA
WILL BE GOING THROUGH NUMEROUS TESTS AND MONITORED FOR ACCURACY.
