AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
252 PM CDT TUE JUL 26 2011

.DISCUSSION...

AN UPPER LEVEL TROF IN THE UPPER LEVELS HAS BROUGHT IN A GOOD
AMOUNT OF DRY AIR ALOFT. IN ADDITION...A WEAK FRONTAL BOUNDARY
CONTINUES TO SLOWLY MAKES ITS WAY SOUTHWARD ACROSS CENTRAL
ALABAMA. THE COMBINATION OF THESE TWO FEATURES HAVE SUPPRESSED
CONVECTION ALONG THE NORTHERN HALF PORTION OF THE FORECAST AREA.
NEVER THE LESS...A GOOD AMOUNT OF LOW LEVEL MOISTURE STILL REMAINS
IN PLACE WHICH MEANS WE COULD STILL SEE ISOLATED TO SCATTERED
SHOWERS AND THUNDERSTORMS EARLY THIS EVENING.

PATTERN WILL BEGIN TO CHANGE AGAIN ON WEDNESDAY. EXPECT FOR DEEP
MOISTURE TO RETURN ACROSS THE AREA AND REMAIN IN PLACE AT LEAST
THROUGH THE WEEKEND.

LONG RANGE MODELS CONTINUE TO INDICATE THAT A STRONG HIGH PRESSURE
RIDGE WILL BE ESTABLISHING ITSELF ACROSS CENTRAL ALABAMA NEXT
WEEK. THIS IN TURN WILL BEGIN TO SUPPRESS RAIN CHANCES AND HELP
TEMPERATURES GO ABOVE NORMAL BY THE MIDDLE PART OF NEXT WEEK.

10/ARM

&&

.AVIATION...
18Z TAF DISCUSSION.

WEAK SURFACE BOUNDARY JUST SOUTH OF THE INTERSTATE 85 CORRIDOR...
WITH AMPLE LOW LEVEL MOISTURE TO THE SOUTH OF THIS AREA AND MAINLY
MID/UPPER LEVEL MOISTURE TO THE NORTH. SCATTERED SHOWERS AND A FEW
T-STORMS TO THE SOUTH OF THIS AREA...BUT THEY SHOULD NOT BE VERY
STRONG AND WOULD ONLY IMPACT TOI. SHOULD HAVE SOME PATCHY FOG ONCE
AGAIN LATE TONIGHT WITH ALL OF THE RAIN WE HAVE HAD ACROSS CENTRAL
ALABAMA. CEILINGS SHOULD NOT BE AS MUCH OF AN ISSUE
TONIGHT...ESPECIALLY ACROSS THE NORTHERN TERMINALS...ALTHOUGH TOI
COULD SEE SOME LOWER CLOUDS DEPENDING ON EXACTLY WHERE THE TROUGH IS
BY THE MORNING.

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.
