What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Birmingham, AL wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 30, 3:18 PM CDT, 2 hours 7 minutes earlier.

Area forecast discussion, Jul 30, 3:18 PM CDT, 2 hours 7 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
318 PM CDT THU JUL 30 2009

.DISCUSSION...AN ACTIVE NIGHT SETTING UP ACROSS ALABAMA AS AN
UNUSUALLY STRONG SHORT WAVE TROF OVER THE ARLATEX REGION LIFTS ENE
AND PUSHES A WEAK SURFACE FRONT INTO NORTH ALABAMA LATER TONIGHT.
NOT ONLY IS THERE SIGNIFICANT UPPER LEVEL LIFT ASSOCIATED WITH
THIS SYSTEM...A SURFACE LOW IS FORECAST TO MOVE ACROSS WESTERN
TENNESSEE AND DEEPEN. THE INCREASING LOW FLOW WILL CAUSE FAVORABLE
WIND PROFILES FOR ROTATING SUPERCELLS AND ISOLATED TORNADOES. ONCE
THE SURFACE BOUNDARY MOVES INTO NW ALABAMA AFTER MIDNIGHT...THERE
IS ALSO THE POSSIBILITY OF HEAVY RAINFALL NORTH OF I-20. THE
DECISION WAS MADE TO NOT ISSUE A FLASH FLOOD WATCH BASED ON THE
LACK OF ANY SIGNIFICANT RAINFALL ACROSS NW COUNTIES DURING THE
PAST FEW DAYS. HOWEVER...RAINFALL AMOUNTS COULD REACH 3 INCHES IN
SOME AREAS...SO LOCALIZED FLOODING A POSSIBILITY.

THE FRONT WILL STALL OUT ACROSS CENTRAL ALABAMA ON FRIDAY WHICH
MEANS HIGH RAIN CHANCES WILL CONTINUE FOR MOST AREAS. DUE TO
EXPECTED CLOUD COVER AND WEAKENING LOW LEVEL INFLOW SOUTH OF
BOUNDARY...THE PRIMARY THREAT ON FRIDAY WILL BE HEAVY RAINFALL..
BUT STRONG STORMS POSSIBLE IF ENOUGH SUNSHINE CAN BREAK OUT AND WARM
SURFACE TEMPERATURES.

MAIN UPPER TROF WILL PASS SOUTH OF AREA FRIDAY NIGHT WITH DRIER MID
LEVEL SPREADING ACROSS CENTRAL ALABAMA....AND LOWERED RAIN CHANCES
FRIDAY NIGHT AND SATURDAY. NEXT SHORT WAVE TROF WILL AFFECT AREA
SATURDAY NIGHT AND SUNDAY. KEPT RAIN CHANCES AT OR BELOW 50
PERCENT BOTH PERIODS...BUT MAY NEED TO BE RAISED IF MODELS
CONTINUE TO SHOW A STRONGER SYSTEM. NEXT WEEK...GFS AND ECMWF MODELS
INDICATE UPPER RIDGE OVER TEXAS COULD SHIFT JUST ENOUGH EASTWARD
TO BREAK CURRENT WET PATTERN...BUT A NORTHWEST FLOW PATTERN CAN
ALSO BE AN ACTIVE WEATHER MAKER FOR THE SOUTHEAST STATES.

58/ROSE

&&

.AVIATION...18Z TAF DISCUSSION.

CEILINGS SHOULD CONTINUE TO RISE TO VFR ACROSS THE AREA OVER THE
NEXT HOUR OR SO.  VFR CONDITIONS SHOULD CONTINUE THROUGH THE
AFTERNOON AND INTO THE EARLY EVENING. SCATTERED SHOWERS AND
THUNDERSTORMS HAVE ALREADY BEGUN TO SHOW UP ON RADAR EARLY THIS
AFTERNOON AND THEY WILL CONTINUE TO DEVELOP AND MOVE EASTWARD OVER
CENTRAL ALABAMA THROUGH THE REMAINDER OF THE AFTERNOON. MENTIONED
VCTS AT ALL SITES AS ACTIVITY WILL BE HIT OR MISS AT BEST.

AN UPPER LEVEL SHORT WAVE TROF WILL APPROACH THE AREA FROM THE WEST
LATE THIS EVENING...AND WILL PUSH EASTWARD ACROSS THE NORTHERN HALF
OF CENTRAL ALABAMA DURING THE OVERNIGHT HOURS. CIGS WILL LOWER TO
MVFR AS THIS SYSTEM MOVES THROUGH. CONFIDENCE IS PRETTY HIGH IN THE
AMOUNT OF RAIN COVERAGE WITH THIS SYSTEM SO KEPT TSRA WORDING IN ALL
NORTHERN TAFS. CONFIDENCE HOWEVER IS LESS IN HOW OR IF THIS SYSTEM
WILL AFFECT MGM AND TOI. AT THIS TIME IT LOOKS AS THOUGH THE
MAJORITY OF THE OVERNIGHT ACTIVITY WILL STAY TO THE NORTH OF THIS
AREA.
