Area forecast discussion, Aug 2, 3:07 PM CDT, 12 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
307 PM CDT THU AUG 2 2012

.DISCUSSION...

A GOOD COVERAGE OF THUNDERSTORMS THIS AFTERNOON ESPECIALLY ACROSS
THE WESTERN TWO-THIRDS OF THE AREA. POPS TONIGHT WILL BE A LAST
MINUTE CALL BUT WILL KEEP IN MIND THAT ANOTHER IMPULSE WILL BE
APPROACHING THE STATE OVERNIGHT. THESE WEAK IMPULSES WILL CONTINUE
TO ROTATE AROUND THE EAST SIDE OF THE UPPER RIDGE THROUGH
SATURDAY. LOOKS LIKE THE COVERAGE OF SHOWERS WILL BE SIMILAR TO
TODAY SO WILL GO AHEAD AND BUMP UP THE POPS ESPECIALLY DURING THE
DAYTIME HOURS WHEN DAYTIME HEATING CAN INTERACT WITH THE UPPER
SUPPORT. THE SEVERE THREAT APPEARS LIMITED TO PERHAPS LOCALIZED
FLOODING.

BY SUNDAY...AN UPPER TROUGH WILL PASS THROUGH THE OHIO VALLEY AND
RE-ENFORCE THE UPPER WEAKNESS OVER THE SOUTHEAST WHILE KEEPING THE
RIDGING SITUATED TO THE WEST. THE NET AFFECT THROUGH THE MIDDLE OF
NEXT WEEK WILL BE TO KEEP THE DEEP SOUTH IN A FAVORABLE POSITION
TO HAVE AT LEAST SCATTERED AFTERNOON SHOWERS/THUNDERSTORMS WHILE
KEEPING TEMPERATURES IN CHECK. WILL ALSO BE KEEPING AN EYE ON THE
TROPICS NEXT WEEK.

&&

.AVIATION...18Z TAF DISCUSSION.

SHOWERS AND THUNDERSTORMS ACROSS THE AREA WILL EXPAND IN COVERAGE
THIS AFTERNOON...AND ARE IMMINENT AT SEVERAL TERMINALS. HAVE TIMED
OUT PREVAILING CONDITIONS/TEMPOS. LOOKING UPSTREAM...EVEN AS THE
CURRENT CONVECTION MOVES ON...ADDITIONAL ACTIVITY WILL REMAIN
POSSIBLE THIS AFTERNOON. STORMS WILL REDUCE VIS SIGNIFICANTLY AS
RAINFALL WILL BE HEAVY. STORMS WILL PRODUCE GUSTY WINDS...WITH SOME
HIGHER THAN CURRENTLY FORECASTED. THE ISOLATED THREAT OF MICROBURSTS
BRINGS WITH IT THE POTENTIAL FOR 60MPH WINDS OR GREATER.

ACTIVITY SHOULD DIMINISH THIS EVENING. EXPECT PATCHY FOG THIS
AFTERNOON...WITH LOWEST VIS AT TERMINALS WHICH RECEIVE SUBSTANTIAL
RAINFALL TODAY. IN ADDITION...FOG/LOW CLOUD LAYER COULD SPREAD INTO
TOI AGAIN TONIGHT...AND HAVE ACCOUNTED FOR THAT POSSIBILITY AFTER
09Z.

ANOTHER ACTIVE DAY IS EXPECTED FRIDAY...WITH THUNDERSTORMS POSSIBLE
BEGINNING DURING THE MORNING.
