AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE BIRMINGHAM AL
317 AM CDT TUE MAY 21 2013

.UPDATE...
FOR INCLUSION OF AMD NOT SKED TEMPORARILY FOR ALL TAFS.

&&

.AVIATION...
06Z TAF DISCUSSION.

DUE TO A LARGE SCALE COMMUNICATIONS FAILURE...OBSERVATIONS FOR
CENTRAL ALABAMA TERMINAL LOCATIONS ARE NOT ABLE TO BE RELIABLY
MONITORED AT THIS TIME. THE TIMETABLE FOR OBSERVATIONS TO RETURN IS
NOT KNOWN...AND THEREFORE WE HAVE INCLUDED AMD NOT SKED TEMPORARILY
INTO ALL TAFS. AS SOON AS OBSERVATIONS RETURN...WE WILL REMOVE THE
AMD NOT SKED WORDING AND CONFIDENCE IN ISSUING NORMAL AMENDMENTS
WILL RETURN. WE WILL KEEP YOU INFORMED WHEN NEW INFORMATION BECOMES
AVAILABLE.

LITTLE CHANGE FROM PREVIOUS TAFS. VFR CONDITIONS AT PRESENT.
BOUNDARY LAYER MOISTURE IS EXPECTED TO INCREASE AS WE MOVE THROUGH
THE OVERNIGHT HOURS WITH LIGHT SOUTHERLY FLOW JUST ALOFT ABOVE THE
SURFACE. FAIRLY CONFIDENT OF MVFR VISIBILITIES BUT CONTINUE TO NOT
BE QUITE AS CONFIDENT ON THE POSSIBILITY OF IFR VISIBILITIES...SO
ONLY A FEW TEMPOS FOR NOW. WINDS ALOFT NEAR SUNRISE MAY BE TOO MUCH
FOR THE LOWER RANGE. ALL LOCALES SHOULD GO BACK TO VFR BY 14/15Z
WITH MIXING EXPECTED.

.PREV DISCUSSION... /ISSUED 838 PM CDT MON MAY 20 2013/

UPDATE...
EVENING UPDATE.

DISCUSSION...

AFTER PREVIOUSLY REMOVING POPS FROM THE SMALL PART OF THE
SOUTHEAST THAT ORIGINALLY HAD THEM TONIGHT...THE FORECAST IS
LARGELY IN GOOD SHAPE. DEW POINTS ARE RUNNING A BIT HIGHER THAN
FORECAST (THIS SEEMS TO BE AN EMERGING TREND)...AND I`M GETTING
THE FEELING THAT CLOUDINESS WILL NOT BE AS WIDESPREAD TONIGHT AS
PREVIOUSLY THOUGHT. OTHERWISE...TEMPS ARE DOING FINE AND WINDS
WILL REMAIN LIGHT.
