AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
1255 PM CDT SUN JUL 30 2006

.UPDATE...ADDED 18Z AVIATION DISCUSSION.

&&

.DISCUSSION...CURRENT RADAR AT 17Z STILL HAS A PERSISTENT AREA OF
RAIN ACROSS THE SOUTHEAST PART OF THE FORECAST AREA. RADAR IS
INDICATING 3+ INCHES OF RAIN ACROSS CHAMBERS AND LEE COUNTIES.

DID AN AFTERNOON UPDATE BASED ON CURRENT TRENDS AND LAPS DATA.
WILL HAVE CHANCE NORTH TO CATEGORICAL SOUTHEAST. DID NOT MAKE ANY
CHANGES TO HIGHS. BASED ON CLOUD COVER WOULD THINK HIGHS SHOULD BE
IN THE UPPER 80S NORTH TO LOWER 90S SOUTH...BUT THE 24 HOUR CHANGE
IS SHOWING WARMER TEMPS THAN YESTERDAY. SO...WILL NOT MAKE ANY
CHANGES TO HIGHS.

&&

.AVIATION...DISCUSSION FOR 18Z TAFS.

FIRST SIX HOURS OR SO OF THIS TAF CYCLE ARE LARGELY BASED ON RADAR
TRENDS...AND ALSO WHAT HAS BEEN THE NORM OVER THE LAST FEW DAYS.
INCLUDED THUNDERSTORMS...EITHER PREVAILING OR TEMPO AT EVERY TAF
SITE.  OF COURSE IFR CONDITIONS WILL OCCUR WHERE THUNDERSTORMS ARE
PRESENT...BUT OTHERWISE MVFR AND VFR CONDITIONS WILL DOMINATE.

CLOUD BASES SHOULD BE AROUND 3000 FEET AS THE CUMULUS FIELD
CONTINUES TO DEVELOP THIS AFTERNOON.  STORM HEIGHTS WILL AVERAGE
AROUND 30000 FEET BUT THE STRONGER STORMS MAY APPROACH 45000.

OVERNIGHT...RAIN AND THUNDERSTORMS SHOULD DISSIPATE SHORTLY AFTER
SUNSET.  PATCHY FOG LOOKS LIKE A GOOD BET ONCE AGAIN.  VISIBILITY
WILL LIKELY DROP TO BETWEEN 3 AND 5 MILES AREA WIDE BETWEEN 09 AND
13Z.

.BMX WATCHES/WARNINGS/ADVISORIES...
