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 4, 4:12 AM CDT, 48 minutes earlier.

Area forecast discussion, Jun 4, 4:12 AM CDT, 48 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
412 AM CDT MON JUN 4 2012

.DISCUSSION...
THE MODEL SUITE DISPLAYS GOOD SYNOPTIC PATTERN AGREEMENT THROUGH THE
WEEK...WHICH BECOMES MORE AMPLIFIED AND BLOCKY. STRONG UPPER LOW
SEEN ON LATEST WATER VAPOR NEARING THE WEST COAST WHILE ANOTHER LOW
WAS NEAR NEW ENGLAND. THE UPPER RIDGE BETWEEN THESE FEATURES WAS
CENTERED OVER THE INTERMOUNTAIN WEST AND WILL GRADUALLY SLIDE INTO
THE PLAINS. EVEN WITH THIS RELATIVE AGREEMENT...THAT IS REALLY ONLY
PART OF THE COMPLEX PICTURE CONCERNING SENSIBLE WEATHER.

MESOSCALE FEATURES AND BOUNDARIES ARE PRESENT SEEMINGLY ALL OVER
THE SOUTHEAST AND LOWER MISSISSIPPI VALLEY. THEREFORE...PLACEMENT
AND TIMING OF THUNDERSTORM ACTIVITY WILL BE PROBLEMATIC. SMALL
ORGANIZED LINE MOVED THROUGH THIS AFTERNOON PRODUCING DAMAGING
WINDS AND HAIL. THIS FEATURE LEFT A BOUNDARY ACROSS PARTS OF WEST
CENTRAL AND SOUTH CENTRAL ALABAMA. THE NEXT LARGER MCS OVERNIGHT
PRODUCED DAMAGING WINDS AND HAIL BUT GENERALLY REMAINED NORTH OF
CENTRAL ALABAMA...BUT PUSHED AN OUTFLOW INTO WEST CENTRAL AND SOUTH
CENTRAL AREAS. UPSTREAM MCS OVER OKLAHOMA WILL SLOWLY PROGRESS SOUTH
AND EAST BUT MAY NOT HAVE ANY DIRECT INFLUENCE HERE. THE
THUNDERSTORMS DEVELOPING BETWEEN THE MCS'S HAS PICKED UP IN COVERAGE
AND INTENSITY THE PAST HOUR OR SO...WITH THE COLD POOL SEEMINGLY
CONSOLIDATING AND ALLOWING STORMS T0 INTENSIFY. CORFIDI VECTORS WORK
THIS ACTIVITY SOUTHEASTWARD. THEREFORE...THERE WILL BE A CHANCE OF
SOME SEVERE THUNDERSTORMS TODAY GENERALLY FROM BOUNDARY
INTERACTION...DIFFERENTIAL HEATING AND ANY UPSTREAM COLD POOL
INFLUENCE THAT MOVES INTO THE AREA. ALL MODELS INDICATE AMPLE
INSTABILITY DEVELOPING BY THIS AFTERNOON. WILL ADJUST POPS A BIT
SOUTHWARD AND WILL CONTINUE THE THREAT OF DAMAGING WINDS AND LARGE
HAIL. ANOTHER MID/UPPER LEVEL TROUGH MOVES BY OVERNIGHT. THIS COULD
BRING ANOTHER ROUND OF THUNDERSTORMS BUT WILL BE HIGHLY DEPENDENT ON
WHAT HAPPENS BETWEEN NOW AND THEN. WILL GO WITH LIKELY POPS FOR A
BETTER PART OF THE NORTHERN TWO THIRDS OF THE AREA. THIS SECONDARY
TROUGH PUSHES A COLD FRONT INTO AND THROUGH THE AREA TUESDAY AND
TUESDAY EVENING. THEREFORE WILL KEEP POPS IN THE HIGH CHANCE VALUES
NEAR AND SOUTH OF THE FRONT. INSTABILITIES WILL REMAIN HIGH AND SOME
STRONG TO SEVERE STORMS MAY DEVELOP NEAR THE FRONT...WITH THE
THREAT OF DAMAGING WINDS AND LARGE HAIL.

MEDIUM RANGE MODELS ARE IN A BIT BETTER AGREEMENT THIS RUN AS TO
WHEN THE FRONT SINKS FAR ENOUGH SOUTHWARD TO REMOVE POPS. THE MODEL
SUITE CONSENSUS MATCHES THE CURRENT FORECAST AND WILL MAKE LITTLE
ADJUSTMENT WEDNESDAY AND BEYOND IN THE POP DEPARTMENT.

IN THE EXTENDED...THE ONLY TRICKY FEATURE WILL BE THE CUT-OFF
ENERGY THAT VERY SLOWLY DRIFTS TOWARD CENTRAL ALABAMA. IT APPEARS
IT WILL HOLD OFF UNTIL AFTER VERY LATE INTO THE WEEKEND OR EARLY
NEXT WEEK.  HIGH AND LOW TEMPERATURES COOL OFF SOMEWHAT AND DO NOT
REALLY REBOUND UNTIL THIS WEEKEND.

75

&&

.AVIATION...
VFR CONDITIONS WILL GENERALLY CONTINUE FOR THE NEXT 24 HRS.
COMPLEX OF STORMS OVER SOUTHERN TN AND NORTHERN AL WILL CONTINUE
TO DIVE SOUTHEAST THROUGHOUT THE OVERNIGHT HOURS AND EFFECT THE
NORTHERN TERMINALS (KBHM KEET KTCL AND KANB) AROUND 08-10Z. MVFR
TO IFR CONDITIONS WILL BE POSSIBLE WHEN TERMINALS ARE DIRECTLY
IMPACTED BY THUNDERSTORMS. INCLUDED TEMPO GROUP TO ACCOUNT FOR
THESE CONDITIONS. SOME MODELS ARE HINTING AT THUNDERSTORMS ENDED
TOMORROW AFTERNOON. HOWEVER...CONFIDENCE STILL REMAINS LOW ABOUT
THE EXACT END TIME FOR VCTS. LATER TAF ISSUANCES AND AMENDMENTS
WILL CONTINUE TO REFINE TIMING.
