Area forecast discussion, Jun 16, 1:05 PM CDT, 2 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
105 PM CDT THU JUN 16 2011

.UPDATE...
DISCUSSION.

&&

.DISCUSSION...

VERY WELL DEFINED PRECIP WATER AXIS ACROSS CENTRAL ALABAMA EARLY
THIS AFTERNOON. THE MOISTURE AXIS COMBINED WITH A SURFACE BOUNDARY
FROM LEFTOVER CONVECTION...SHOULD LIMIT COVERAGE THIS AFTERNOON.
THE BEST CHANCE FOR THUNDERSTORMS WILL BE ALONG AND SOUTH OF THIS
BOUNDARY WHERE THE BEST MOISTURE RESIDES. THIS APPEARS TO BE FROM
ALICEVILLE TO MARION TO MONTGOMERY TO PHENIX CITY. ISOLATED
DEVELOP IS POSSIBLE NORTH BUT WILL FEW AND FAR BETWEEN. MICROBURST
POTENTIAL SOUTH IS IN THE HIGH RANGE AND WITH THE INSTABILITY IN
PLACE...SOME STORMS MAY BE STRONG TO SEVERE. STRAIGHT LINE WIND
GUSTS AND HAIL WILL BE THE THREATS THROUGH AROUND 8 PM. TEMPS
SEVERAL DEGREES COOLER TODAY THAN YESTERDAY...ALTHOUGH HIGHS WILL
STILL TOP OUT IN THE 90S.

75

&&

.AVIATION...18Z TAF DISCUSSION.

ISOLATED TO SCATTERED THUNDERSTORMS WILL CONTINUE TO DEVELOP THIS
AFTERNOON...MAINLY ACROSS SOUTH CENTRAL ALABAMA WHERE MOISTURE IS
HIGHER AND LEFTOVER BOUNDARIES COULD PROVIDE A FOCUS FOR
DEVELOPMENT. STRONGER STORMS COULD PRODUCE GUSTY WINDS AND HAIL.
MOST LIKELY LOCATIONS FOR RAIN WILL BE MGM AND TOI. A CONVECTIVE
COMPLEX PUSHING TOWARDS THE MID MISSISSIPPI VALLEY WILL KEEP THE
POSSIBILITY OF THUNDERSTORMS IN THE FORECAST PAST SUNSET FOR SEVERAL
HOURS. WILL MAKE AMENDMENTS FOR TS THROUGH THE AFTERNOON AS NEEDED.

PATCHY FOG IS POSSIBLE OVERNIGHT PRIMARILY AT LOCATIONS THAT RECEIVE
RAIN THIS AFTERNOON. DO NOT EXPECT VISIBILITIES TO DROP BELOW MVFR.
WINDS THIS AFTERNOON...OUTSIDE OF CONVECTIVE DEVELOPMENT...WILL
PRIMARILY BE OUT OF THE SOUTHWEST AT BETWEEN 5 AND 10 KTS.

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.

.PREV DISCUSSION... /ISSUED 1242 PM CDT THU JUN 16 2011/

UPDATE...FOR AVIATION DISCUSSION.

DISCUSSION...

MOST OF LAST NIGHT'S ACTIVITY HAS DIED OFF...BUT STILL SEEING A
FEW STORMS TRYING TO DEVELOP ON OLD OUTFLOW BOUNDARIES ROAMING
AROUND ACROSS THE SOUTHERN PORTIONS OF THE AREA. A WEAK BOUNDARY
WILL CONTINUE TO PUSH SOUTHWARD ACROSS THE AREA TODAY..AND WITH
SUFFICIENT MOISTURE IN PLACE...COULD SEE SOME ISO TS ACROSS THE
SOUTHERN PORTIONS FOR THE AREA THIS AFTN. WILL KEEP SLIGHT CHANCE
POPS IN FOR THIS AREA THRU THE DAY. OTHERWISE...EXPECT PARTLY
CLOUDY SKIES AND TEMPERATURES RISING INTO THE 90S.

LOOKS LIKE A COUPLE OF WEAK UPPER LEVEL IMPULSES WILL SLIDE SEWD
TOWARD THE AREA IN THE THU NIGHT THRU FRI NIGHT TIME FRAME. DON'T
SEE ANY MAJOR IMPACTS WITH THESE FEATURES...BUT THEY COULD PROVIDE
JUST ENOUGH LIFT FOR THE DEVELOPMENT OF SOME ISO STORMS. TONIGHT
THERE WILL BE A SMALL CHANCE OF A SHOWER/STORM ACROSS THE ENTIRE
CWA...BUT THE FOCUS WILL SHIFT TO THE EASTERN HALF ON FRI AS THE
UPPER LEVEL RIDGE BEGINS TO BUILD BACK IN.

FOR THE WEEKEND AND INTO EARLY NEXT WEEK...DRY AND HOT CONDITIONS
WILL PREVAIL HAS THE UPPER RIDGE BECOMES THE DOMINANT WEATHER
FEATURE. TEMPERATURES WILL BE 5 TO 10 DEGREES ABOVE NORMAL THRU
THE PERIOD. AFTN HIGHS WILL BE IN THE MID TO UPPER 90S...WITH A
COUPLE 100 DEGREE READINGS POSSIBLE. RH VALUES WILL BE RATHER LOW,
BUT HEAT INDEX VALUES WILL STILL BE IN THE LOW 100S IN MANY
LOCATIONS. OVERNIGHT LOWS WILL GENERALLY BE IN THE UPPER 60S TO
LOW 70S.

LONG RANGE MODELS SHOW THE RIDGE BREAKING DOWN BY LATE NEXT WEEK
AND MOISTURE INCREASING. PW VALUES OFF FORECAST SOUNDINGS FOR BHM
INCREASE TO AROUND 2 INCHES ON FRI. HOPEFULLY THE MODELS ARE ON TO
SOMETHING AND WE WILL HAVE A DECENT SHOT AT SOME MUCH NEEDED
RAINFALL BY THE END OF NEXT WEEK.
