The facts

Issued: Jul 28, 2009, 3:53 PM CDT (20:53 UTC)
Expired: Jul 28, 2009, 4:30 PM CDT
In force: 37 min

Counties Autauga County, AL, Elmore County, AL, Lowndes County, AL, Montgomery County, AL

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Birmingham, AL (KBMX), launched 12:00Z, 8.9 hours before the alert went out and 83 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

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 28, 3:06 PM CDT, 47 minutes earlier.

Area forecast discussion, Jul 28, 3:06 PM CDT, 47 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
306 PM CDT TUE JUL 28 2009

.DISCUSSION...SHORT WAVE TROF OVER ARKANSAS CONTINUES TO PLOD
EASTWARD AND WILL BRING NUMEROUS SHOWERS AND THUNDERSTORMS TO
CENTRAL ALABAMA THROUGH THE EVENING HOURS. THUNDERSTORMS HAVE BEEN
CONFINED TO AREAS ACROSS SOUTH ALABAMA WHERE LESS CLOUD COVER HAS
ALLOWED FOR MORE HEATING AND INSTABILITY. A NEW LINE OF STORMS HAS
DEVELOPED FROM TUPELO TO JACKSON MISSISSIPPI. THERE HAS BEEN
ENOUGH CLEARING ACROSS EAST MISSISSIPPI TO ALLOW TEMPERATURES TO
CLIMB INTO THE MIDDLE AND UPPER 80S...AND SURFACE BASED CAPE VALUES
ARE 2500-3000 J/KG. THERE IS STILL POTENTIAL FOR SEVERE THUNDERSTORMS
THROUGH THE EARLY EVENING HOURS...MAINLY WEST OF I-65. FORECAST
WILL CONTINUE WITH LIKELY POPS OVERNIGHT AS SHORT WAVE TROF
APPROACHES THE AREA.

EVEN THOUGH PRIMARY SHORT WAVE TROF WILL PUSH EAST OF AREA BY
WEDNESDAY MORNING...A MID LEVEL INSTABILITY WILL REMAIN ACROSS THE
AREA WITH PRECIPITABLE WATER VALUES HOLDING NEAR 2 INCHES. EXPECT
NUMEROUS SHOWERS AND THUNDERSTORMS ONCE AGAIN ON WEDNESDAY...BUT
WITH LESS UPPER LEVEL SUPPORT...STORMS SHOULD STAY BELOW SEVERE
LIMITS. ANOTHER SIGNIFICANT SHORT WAVE TROF WILL DROP INTO THE
PLAINS STATES WEDNESDAY NIGHT. BOTH NAM AND GFS MODELS KEEP
STRONGER AND MORE ORGANIZED CONVECTION TO THE NORTHWEST OF ALABAMA
WEDNESDAY NIGHT AND THURSDAY...EVEN THOUGH GFS DOES BRING A
BULLSEYE OF RAINFALL ACROSS EXTREME NORTH ALABAMA LATE WEDNESDAY
NIGHT...BUT THIS SEEMS A LITTLE TO FAR REMOVED FROM ADVANCING
SHORT WAVE TROF. THURSDAY NIGHT AND FRIDAY COULD BE ACTIVE ACROSS
AREA AS BOTH MODELS SHOW A SURFACE FRONT MOVING INTO NORTHWEST
ALABAMA ON FRIDAY. THE SURFACE BOUNDARY STALLS OUT ACROSS CENTRAL
ALABAMA BY SATURDAY...SO THERE MAY BE A DECREASE IN RAIN CHANCES
NORTH OF I-20...BUT CHANCES OF RAIN WILL STAY IN THE FORECAST
THROUGH THE FIRST PART OF NEXT WEEK.

58/ROSE

&&

.AVIATION...18Z TAF DISCUSSION.

SCATTERED SHOWERS WILL PLAGUE CENTRAL ALABAMA THIS AFTERNOON...AHEAD
OF A MUCH LARGER SHIELD OF RAIN AND THUNDER.  THESE WILL LIKELY LAST
THROUGH THE OVERNIGHT HOURS...AND INTO THE MORNING...DISSIPATING
FROM WEST TO EAST ON WEDNESDAY.

FOR NOW...HAVE PUT A PREVAILING MVFR AT ALL SITES THIS
AFTERNOON...BUT THERE WILL BE CHANCE FOR AN AMENDMENT LATER THIS
AFTERNOON AS THE MAIN SHIELD OF RAIN MOVES INTO THE AREA.  THERE IS
A THREAT OF STRONG GUSTY WINDS TOO...SO WILL HAVE TO WATCH THE
UPSTREAM OBS AS THESE STORMS MOVE THROUGH THE AREA.

KEET CEILOMETER IS STILL OUT OF COMMISSION...WAITING FOR THE
DELIVERY OF A PART.  SHOULD BE BACK UP THIS EVENING OR TOMORROW AT
THE LATEST...DEPENDING ON WHEN THE SHOWERS MOVE OUT OF THE AREA.
