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 Huntsville, AL wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 27, 3:49 PM CDT, 4 minutes earlier.

Area forecast discussion, Jul 27, 3:49 PM CDT, 4 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HUNTSVILLE AL
349 PM CDT FRI JUL 27 2012

.DISCUSSION...
ON THE SYNOPTIC SCALE...A POSITIVELY-SHEARED MID-LEVEL VORT MAX
CURRENTLY LOCATED OVER THE GREAT LAKES WILL ADVANCE EASTWARD INTO
WESTERN PORTIONS OF NEW ENGLAND BY TOMORROW MORNING. THE CENTRAL
TENNESSEE VALLEY REMAINS ON THE SOUTHERN EDGE OF THE STRONGER HEIGHT
FALLS ASSOCIATED WITH THIS FEATURE...AND WITHIN A COL REGION OF
RELATIVELY WEAK STEERING FLOW BETWEEN TWO STRENGTHENING SUBTROPICAL
HIGHS -- ONE ACROSS THE WESTERN NORTH ATLANTIC AND THE OTHER ACROSS
THE SOUTHERN PLAINS. REGARDLESS...NUMEROUS SHOWERS AND THUNDERSTORMS
HAVE DEVELOPED ACROSS THE AREA...AS A WEAK MID-LEVEL SHEAR AXIS
INTERACTED WITH THE WARM/MOIST AND UNSTABLE AIR MASS IN PLACE ACROSS
THE LOCAL AREA. THIS ACTIVITY WILL LIKELY DIMINISH WITHIN A COUPLE
HOURS OF SUNSET...BUT WILL CARRY SLIGHT CHANCE POPS INTO THE FIRST
PART OF THE EVENING HOURS TO ACCOUNT FOR LINGERING ACTIVITY. AS SKIES
BEGIN TO CLEAR LATE TONIGHT...PATCHY FOG WILL LIKELY DEVELOP --
PERHAPS BECOMING A BIT MORE WIDESPREAD IN AREAS THAT RECEIVE HEAVIER
PRECIPITATION TODAY.

MODELS AGREE THAT A STRONGER UPPER-LEVEL SPEED MAX WILL DIG
SOUTHEASTWARD ACROSS THE UPPER MISSISSIPPI VALLEY LATER TODAY...AND
INTO THE OHIO VALLEY BY SATURDAY MORNING. AS THIS FEATURE MOVES INTO
THE BASE OF THE NEW ENGLAND TROUGH...A WEAK ATTENDANT SURFACE COLD
FRONT WILL PUSH SOUTHWARD THROUGH THE FORECAST AREA ON SATURDAY
AFTERNOON. ALTHOUGH THE REGION OF STRONGEST LARGE SCALE ASCENT
ASSOCIATED WITH THE PREVIOUSLY MENTIONED SPEED MAX WILL LIKELY REMAIN
ACROSS THE SOUTHERN APPALACHIANS...A FEW SHOWERS AND STORMS MAY
DEVELOP ALONG THE COLD FRONT AS IT PUSHES INTO THE REGION AND
MAXIMIZES LOW-LEVEL CONVERGENCE. HOWEVER...IT DOES APPEAR THAT AN
INCREASINGLY SUBSIDENT AIR MASS ALOFT -- DUE TO THE EASTWARD
EXPANSION OF THE SOUTHERN PLAINS MID-LEVEL HIGH -- WILL THE LIMIT THE
COVERAGE OF SHOWERS/STORMS AND WILL KEEP POPS IN THE SLIGHT CHANCE
RANGE TO REFLECT THIS. THE SOUTHERN PLAINS RIDGE WILL BEGIN TO WEAKEN
SLIGHTLY AND RETREAT TO THE WEST ON SATURDAY NIGHT...AS THE FIRST IN
SERIES OF MID-LEVEL WAVES EMBEDDED IN NORTHWEST FLOW ALOFT TRACKS
SOUTHEASTWARD ACROSS WESTERN KENTUCKY AND MIDDLE/EASTERN TENNESSEE.
GIVEN THE INTRUSION OF DRY LOW-LEVEL AIR IN THE WAKE OF THE COLD
FRONT SATURDAY...LITTLE THREAT FOR PRECIPITATION WILL EXIST WITH THIS
FEATURE. WARM AND DRY CONDITIONS WILL LIKELY CONTINUE INTO
SUNDAY...BUT WITH THE MID-LEVEL HIGH CONTINUING TO WEAKEN AND
RETROGRADE ACROSS THE RED RIVER VALLEY OF NORTHERN TEXAS/SOUTHERN
OKLAHOMA...CONDITIONS WILL BECOME INCREASINGLY FAVORABLE FOR
DISTURBANCES IN THE NORTHWEST FLOW ALOFT TO BRING SHOWERS/STORMS TO
THE REGION AND HAVE INCLUDED SLIGHT CHANCE POPS ON SUNDAY NIGHT.

VERY LITTLE HAS CHANGED IN THE FORECAST REASONING DURING THE EXTENDED
PERIOD...WITH THE MID-TROPOSPHERIC HIGH FORECAST TO BECOME
ESTABLISHED ACROSS THE SOUTHERN ROCKIES. AS THIS OCCURS...SEVERAL
SHORTWAVE TROUGHS EMBEDDED IN NORTHWEST FLOW WILL TRACK SOUTHEASTWARD
ACROSS THE REGION AND INTO A BROAD LONG WAVE TROUGH SITUATED ACROSS
THE EASTERN CONUS. THESE DISTURBANCES WILL BRING A HEIGHTENED THREAT
FOR SHOWERS AND THUNDERSTORMS TO THE TENNESSEE VALLEY NEXT WEEK --
PARTICULARLY ON TUESDAY/WEDNESDAY AND PERHAPS THURSDAY. THE SOUTHERN
ROCKIES RIDGE MAY BEGIN TO BUILD EASTWARD BY THE END OF THE FORECAST
PERIOD AS A STRONGER UPSTREAM TROUGH DIGS SOUTHEASTWARD INTO THE
NORTHERN ROCKIES...AND THIS MAY RESULT IN A MORE DIURNALLY-DRIVEN
PRECIPITATION PATTERN DEVELOPING LATE NEXT WEEK. BOTH HIGH AND LOW
TEMPERATURES WILL BE 3-5 DEGREES ABOVE CLIMATOLOGICAL NORMAL
VALUES...WITH HIGHS IN THE LOWER/MID 90S AND LOWS IN THE LOWER/MID
70S.

70/DD

&&

.AVIATION...
/ISSUED 1242 PM CDT FRI JUL 27 2012/
FOR 18Z TAFS...THE APPROACHING FRONTAL BOUNDARY WILL BRING SHRA/TSRA
TO THE AREA TODAY...POSSIBLY IMPACTING EITHER TERMINAL THIS
AFTERNOON WITH BRIEF GUSTY WINDS AND REDUCED VIS/CIGS. AFTER THE
SHRA/TSRA DISSIPATE THIS EVENING...PATCHY FOG MAY DEVELOP...AND THIS
MAY ALSO IMPACT EITHER TERMINAL LATE TONIGHT/EARLY SATURDAY MORNING.
OUTSIDE OF THE TSRA/BR WINDOWS...VFR CONDITIONS ARE ANTICIPATED WITH
MOSTLY LIGHT SOUTHWEST WINDS.
