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 Jun 28, 11:00 AM CDT, 1 hour 4 minutes earlier.

Area forecast discussion, Jun 28, 11:00 AM CDT, 1 hour 4 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
1100 AM CDT TUE JUN 28 2011

.UPDATE...MORNING WEATHER.

&&

.DISCUSSION...

OUTFLOW FROM FIRST MCS IS CURRENTLY PUSHING SSW ACROSS THE AREA
AND HAS JUST PASSED THRU BHM. THIS SYSTEM HAS WEAKENED SIGNIFICANTLY
BUT ADDITIONAL TSTM DEVELOPMENT IS LIKELY ALONG THE OUTLFOW BOUNDARY. THE
STRONGER SYSTEM WILL PUSH SE INTO THE NW COUNTIES WITHIN THE NEXT
HALF HOUR. THIS MCS IS MARKED BY AN ARC-SHAPED LINE OF STRONG TO
SEVERE TSTMS AND VERY HEAVY RAINFALL. HAVE INCREASED POPS TO DEF
IN THE NW AND KEPT CHNC IN THE SE. IF THIS SYSTEM HOLDS TOGETHER
THEN MAY HAVE TO INCREASE POPS IN THE SE AS WELL.

SPC HAS THE ENTIRE CWA IN A SLIGHT RISK FOR THE THREAT OF
DAMAGING WINDS AND MARGINAL SVR HAIL. A SVR TSTM WATCH HAS BEEN
ISSUED FOR GENERALLY THE SWRN HALF OF THE CWA THRU 6 PM. CAPES ARE
UPWARDS OF 4000 J/KG ACROSS THE CENTRAL PORTIONS OF THE AREA...JUST
AHEAD OF THE OUTFLOW BOUNDARY FROM THE FIRST MCS. LIFTED INDICES
ARE ALSO AT OR NEAR -8 IN THIS SAME CORRIDOR...WHICH STRETCHES
FROM PICKENS CO SEWD TOWARD MGM. THIS IS THE FAVORED TRACK OF THE
MCS IN NORTHERN MS...SO EXPECT SVR THREAT TO CONTINUE THRU THE
AFTN HRS. PW VALUES ARE BETWEEN 1.75 AND 2 INCHES...SO HEAVY
RAINFALL WILL CONTINUE TO BE A THREAT WITH TSTMS TODAY. WILL HAVE
TO CLOSELY MONITOR SPEED OF INDIVIDUAL TSTMS AND THE OVERALL
SYSTEM FOR POTENTIAL LOCALIZED FLASH FLOODING CONCERNS. THE NW
COUNTIES WILL BE AN AREA TO WATCH AS BOTH OUTFLOWS HAVE MERGED IN
THE VICINITY AND THE AREA WILL LIKELY SEE AN EXTENDED PERIOD OF
RAINFALL.

19

&&

.AVIATION...12Z TAF DISCUSSION.

SOME LOCALIZED PATCHY FOG ACROSS THE AREA THIS MORNING...BUT IT
SHOULD MIX OUT QUICKLY BY 14Z. OTHERWISE...CONVECTIVE COMPLEX IN
TENNESSEE IS APPROACHING NORTHERN BORDER OF ALABAMA...BUT SHOULD
LOSE SOME OF ITS PUNCH AS IT ENCOUNTERS SOMEWHAT DRIER AIR MASS.
SYNOPTIC LIFTING ASSOCIATED WITH FRONT TO OUR NORTH AND WEST WILL
COMBINE WITH MOIST UNSTABLE AIR MASS TO PRODUCE MORE SCATTERED
THUNDERSTORMS MAINLY FROM LATE MORNING THROUGH THE AFTERNOON AND
EVENING. WILL CARRY PREVAILING SHRA WITH VCTS AFTER 15Z. TIMING OF
TSRA AT THIS POINT STILL UNCERTAIN SO AM NOT INCLUDING TEMPO GROUPS
AT THIS TIME BUT IFR OR MVFR LIKELY TO OCCUR AT SOME TAF SITES IN
STRONGER STORMS. SOME OF THE STORMS TODAY COULD BE LOCALLY STRONG TO
SEVERE...WITH STRONG STRAIGHT LINE WINDS...HAIL AND LOCALIZED HEAVY
RAINFALL. STORMS SHOULD BE DIMINISHING BY 02Z NORTHERN SITES AND BY
04Z MGM AND TOI. SOUTHWEST WINDS TODAY WILL SHIFT TO NORTHWEST BY
EARLY TONIGHT AS BOUNDARY PUSHES SOUTH ACROSS THE AREA.

FINALLY HAVE ALSO INCLUDED BR IN TAFS AFTER 09Z SINCE MOST PLACES
WILL LIKELY SEE SOME RAIN TODAY...AND WITH MOIST GROUND SURFACE FOG
DEVELOPMENT WILL LIKELY OCCUR.

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.

41

&&

.PREV DISCUSSION... /ISSUED 615 AM CDT TUE JUN 28 2011/

THE PATTERN OVER CENTRAL ALABAMA WILL BE IN TRANSITION THROUGHOUT
THE DAY TODAY AS THE RIDGE OF HIGH PRESSURE RETREATS WESTWARD.
THIS WILL ALLOW A COLD FRONT...CURRENTLY DRAPED FROM MICHIGAN
SOUTH TO WESTERN KENTUCKY AND WESTWARD TOWARD THE TEXAS
PANHANDLE...TO SLIDE TOWARD CENTRAL ALABAMA BY THE AFTERNOON. THIS
FRONT EVENTUALLY CLEARS BY WEDNESDAY AFTERNOON...AND THE RIDGE
BUILDS BACK IN AND WILL BE IN PLACE ACROSS THE REGION BY THE END
OF THE WEEK...ALONG WITH A RETURN TO THE HOT CONDITIONS FOR THE
FOURTH OF JULY WEEKEND.

DISCUSSION...

AS FOR TODAY...CURRENTLY WATCHING YET ANOTHER MCS MOVING EAST
SOUTHEAST ACROSS TENNESSEE RIGHT NOW. IF FACT THE WESTERN TWO
THIRDS OF TENNESSEE AND EXTREME NORTHERN ALABAMA COUNTIES ARE
ALREADY IN A SEVERE THUNDERSTORM WATCH THIS MORNING. CURRENT
VECTORS ARE TAKING THIS MCS ACROSS NORTHEASTERN ALABAMA THIS
MORNING AND MAY IMPACT AREAS EAST OF I-65 AND NORTH OF I-20
THROUGH THE MORNING HOURS. THE MAIN THREAT WITH THESE STORMS WILL
BE WIND AND HAIL AS WELL AS HEAVY RAINFALL. THIS ACTIVITY IS
DEVELOPING ALONG A PRE-FRONTAL WEAKNESS. ANOTHER AREA OF SHOWERS
AND THUNDERSTORMS HAVE DEVELOPED CLOSER TO THE FRONT IN MISSOURI
AND WILL FOLLOW IN THE FOOTSTEPS OF THE FIRST MCS...JUST A TOUCH
FURTHER SOUTH. THIS WILL LIKELY BE THE MAIN WAVE EXPECTED TO MOVE
THROUGH THE AREA TODAY. WILL CONTINUE TO HIGHLIGHT SEVERE
THUNDERSTORMS WITH DAMAGING WINDS AND EVEN LARGE HAIL AS THE MAIN
THREATS FOR TODAY. HOWEVER...STILL EXPECTING A FAIRLY SLOW MOVING
FRONT...SO LOCALIZED FLOODING WILL ALSO NEED TO BE MONITORED
DURING THE DAY.

LOOKING FOR THE MAIN SEVERE ACTIVITY TO BEGIN TO DWINDLE DOWN
AFTER 9 PM TONIGHT WITH THE LOSS OF THE ADDITIONAL HEATING OF THE
DAY...ALTHOUGH ISOLATED STRONG STORMS WILL CONTINUE TO BE POSSIBLE
ALONG THE FRONT UNTIL IT CLEARS ON WEDNESDAY. AT THIS TIME IT DOES
APPEAR THE FRONT WILL CLEAR THE AREA. THE EURO WHICH WAS THE
STANDOUT YESTERDAY AND KEPT THE FRONT IN THROUGH THURSDAY NOW
AGREES WITH THE CLEARING BY WEDNESDAY NIGHT AND THE RIDGE BUILDING
IN THURSDAY AND LASTING THROUGH THE FOURTH OF JULY WEEKEND.
SPEAKING OF THE FOURTH OF JULY WEEKEND...HOT CONDITIONS WILL BE
BACK IN PLAY AND HEAT INDICES WILL RANGE FROM 100 TO 105 DEGREES
WITH TEMPERATURES IN THE UPPER 90S TO NEAR 100 DEGREES...SO PLAN
ON DRINKING PLENTY OF FLUIDS IF YOU HAVE OUTDOOR PLANS OVER THE
WEEKEND.

BY EARLY NEXT WEEK...THE BERMUDA HIGH TRIES TO BUILD IN FROM THE
SOUTH AND THE MAIN RIDGE RETREATS BACK TO THE WEST. THIS WILL PUT
CENTRAL ALABAMA IN A WEAKNESS AREA BETWEEN THE 2 RIDGES...ALONG
FOR A RETURN OF THE SOUTHERLY FLOW AND INCREASED RAIN CHANCES BY
SUNDAY NIGHT THROUGH THE FOURTH OF JULY ITSELF. AT THIS TIME IT
APPEARS AS THIS MAY JUST BE DIURNALLY DRIVEN STORMS WITH CLEARING
BY THE EVENING HOURS...BUT ALOT OF TIME FOR THIS TO BE LOOKED AT.
