AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
1237 PM CDT TUE JUN 12 2007

.UPDATE...FOR AVIATION DISCUSSION.

&&

.DISCUSSION...DID SOME MINOR CHANGES TO SKY COVER AND TEMPERATURES
MAINLY ACROSS THE EASTERN SECTIONS.  AS WE MOVE INTO AND THROUGH
THE AFTERNOON...EXPECT ISOLATED TO SCATTERED THUNDERSTORMS TO
DEVELOP ACROSS THE EASTERN THIRD.  CURRENT FORECAST HANDLES THIS
JUST FINE.  UPDATE ALREADY OUT.

KSL

&&

.AVIATION...18Z TAF DISCUSSION.

NO WIDESPREAD AREAS OF IMPACT WEATHER EXPECTED OVER THE NEXT 24
HOURS...BUT THERE ARE A COUPLE SMALL ISSUES TO KEEP AN EYE ON.  HAZE
REMAINS A BIT OF A PROBLEM...ESPECIALLY AROUND ANB.  HAVE GONE WITH
A LARGELY PERSISTENCE BASED FORECAST FOR THE HAZE.  VISIBILITY
RESTRICTIONS SHOULD REACH THEIR PEAK AROUND 11-13Z...AND (EXCEPT FOR
PERHAPS ANB) SHOULD REMAIN IN THE MVFR CATEGORY AT WORST.

ISOLATED TO SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP THIS
AFTERNOON AND EVENING.  AT THIS TIME...I DONT SEE ANY ONE LOCATION
WITH ANY MORE THAN A 20-30 PERCENT CHANCE OF RAIN.  HAVE THEREFORE
LEFT THUNDERSTORMS OUT OF THE TAFS FOR NOW...BUT MAY NEED TO AMEND
THINGS ONCE STORMS DO DEVELOP.  SHORTWAVE ENERGY DROPPING SOUTHWARD
FROM THE VIRGINIAS INTO THE SOUTHEAST STATES COULD ACTUALLY CAUSE
THUNDERSTORMS TO DEVELOP/CONTINUE LONGER THAN TYPICAL INTO THE
EVENING AND OVERNIGHT HOURS.  LOCATIONS WITH THE BEST CHANCES STORMS
(AND POSSIBLE EVENTUAL AMENDMENTS) ARE ANB...MGM...AND TOI.
