644 PM CDT THU JUN 9 2011

.UPDATE...AVIATION DISCUSSION.

&&

.PREV DISCUSSION... /ISSUED 310 PM CDT THU JUN 9 2011/

DISCUSSION...

NO SIGNIFICANT CHANGES FROM PREVIOUS FORECASTS AND DISCUSSIONS ARE
ANTICIPATED IN THIS FORECAST PACKAGE.  WE DID UPDATE THE POPS FOR
THE REMAINDER OF THE AFTERNOON AS A FEW CELLS HAVE POPPED UP RIGHT
IN THE MIDDLE OF AXIS OF MINIMUM PW'S.  ALTHOUGH THE UPPER-LEVEL
RIDGE IS NOT GOING COMPLETELY AWAY THROUGH THE UPCOMING WEEKEND...IT
DOES WEAKEN EVER SO SLIGHTLY.  THIS SUBTROPIC RIDGE IS SEPARATING
THE WESTERLIES TO OUR NORTH FROM THE UPPER-LEVEL LOW PRESSURE OVER
THE GULF OF MEXICO.  BOTH THE NAM AND SREF ARE FAIRLY WET OVER
ALABAMA FRIDAY AFTERNOON...WHILE GFS AND ECMWF STAY FAIRLY BONE
DRY.  THERE IS WIDESPREAD COVERAGE OVER GEORGIA TODAY...SO THE WET
WEATHER IS NOT THAT FAR AWAY.  EVEN THE DRY GFS INCREASES THE PW'S
OVER ALABAMA ON FRIDAY.  AM LEANING TOWARD AT LEAST CLIMO TYPE OF
POP'S FOR FRIDAY AND SATURDAY.

WITH THE RIDGE BEING CENTERED OVER NORTHERN MEXICO BY
MONDAY...NORTHWEST FLOW ALOFT BECOMES OUR MAIN FLOW PATTERN NEXT
WEEK.  SO...NOT ONLY IS THERE THE DAYTIME HEATING FACTOR...BUT
SHOWERS AND THUNDERSTORMS COULD ALSO PROPAGATE INTO THE FORECAST
AREA FROM THE NORTHWEST.

TEMPERATURE-WISE...GOING TO KEEP ROLLING OUT MAX TEMPERATURES
SLIGHTLY ABOVE GUIDANCE DUE TO DROUGHT CONDITIONS.

03

.AVIATION...00Z TAF DISCUSSION.

ISOLTED TO SCATTERED THUDNERSTORMS WILL CONTINUE ACROSS THE AREA FOR
THE NEXT COUPLE HOURS. MOST OF THE ACTIVITY IS CURRENTLY ACROSS THE
EASTERN PORTION OF THE AREA...AND WILL UPDATE TAFS IF AND WHEN
CONVECTION APPROACHES ANY TERMINALS. PATCHY FOG IS POSSIBLE
TONIGHT...ESP AT LOCATIONS WHICH RECEIVE RAINFALL. SCATTERED
THUNDERSTORMS ARE POSSIBLE FRIDAY AFTERNOON...AND WILL CARRY VCTS
FOR ALL TERMINALS.

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.
