The radar

The Northeast Alabama radar (KHTX), 63 km from the middle of the area, began a volume at 02:44 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

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.

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 Mar 23, 6:45 PM CDT, 2 hours 58 minutes earlier.

Area forecast discussion, Mar 23, 6:45 PM CDT, 2 hours 58 minutes before

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE HUNTSVILLE AL
645 PM CDT WED MAR 23 2011

.UPDATE...FOR 00Z TAFS
&&

.AVIATION...SQUALL LINE IS CURRENTLY MOVING E THROUGH CNTRL TN. SRN
EXTENT OF THIS CONVECTIVE LINE MAY BUILD SWD ENOUGH TO AFFECT PARTS
OF NRN AL THROUGH 05Z. ANY THREAT TO THE TERMINALS LOOKS TO BE AOA
01-03Z FOR KMSL...AND 02-04Z FOR KHSV. STRONG/VRB GUSTY WINDS WITH
REDUCED VIS LOOK TO BE THE PRIMARY THREAT WITH THIS LINE OF TSTMS.
SFC WINDS WILL THEN BEGIN TO TURN TOWARD THE WNW FROM W TO E AFTER
03Z...AS A COLD FRONT BEGINS TO MOVE THROUGH THE CNTRL TN VALLEY.
VFR CONDITIONS ARE ALSO XPCTED TO PREVAIL THROUGH THE AFTERNOON
PERIOD BEGINNING LATE THIS EVENING...ALTHOUGH MID LEVEL CEILINGS
LOOK TO PREVAIL THROUGH THE FORECAST PERIOD.
&&

.DISCUSSION...THE PRIMARY WEATHER FEATURE OF INTEREST FOR THE
UPCOMING 24-HOUR PERIOD IS A BROAD UPPER LOW -- CURRENTLY LOCATED
OVER THE UPPER MISSISSIPPI VALLEY -- WHICH IS PROGGED TO DEVOLVE
INTO A POSITIVELY TILTED SHORTWAVE TROUGH AND SHIFT RAPIDLY
SOUTHEASTWARD ACROSS THE CENTRAL APPALACHIANS AND OFF THE
MID-ATLANTIC COAST BY THURSDAY MORNING. MEANWHILE...PARTLY TO MOSTLY
CLOUDY SKIES AND WARM TEMPERATURES PERSIST ACROSS THE TENNESSEE
VALLEY DOWNSTREAM FROM THE SURFACE COLD FRONT ACCOMPANYING THIS
SYSTEM...WITH GUSTY SOUTHWEST WINDS EXPECTED THROUGH EARLY EVENING.
SCATTERED SHOWERS/THUNDERSTORMS WILL EVENTUALLY IMPACT THE ENTIRE
FORECAST AREA...BEFORE PRECIPITATION COMES TO AN END THIS EVENING AS
THE COLD FRONT SWEEPS SOUTHEASTWARD. HOWEVER...WITH FRONTAL PASSAGE
EXPECTED IN THE 24/00-04Z TIME FRAME...WILL NEED TO MAINTAIN A
CHANCE OF SHOWERS AND STORMS THROUGH EARLY EVENING FOR MOST
LOCATIONS.

BEYOND TONIGHT...MODELS DEVELOP WEAK SHORTWAVE RIDGING ALOFT ACROSS
NORTHERN ALABAMA AND SOUTHERN MIDDLE TENNESSEE...BETWEEN THE FIRST
SHORTWAVE TROUGH EJECTING NORTHEASTWARD ACROSS THE WESTERN NORTH
ATLANTIC AND ANOTHER/WEAKER UPPER LOW SHIFTING EASTWARD ACROSS THE
FOUR CORNERS REGION AND THIS FEATURE WILL ENSURE DRY CONDITIONS FROM
LATE TONIGHT THROUGH AT LEAST THE FIRST HALF OF FRIDAY. MODERATE COLD
ADVECTION WILL BE IN PLACE THROUGH THE MAJORITY OF THE DAY ON
THURSDAY...AS A MODIFIED ARCTIC HIGH CENTERED NORTH OF HUDSON BAY
BUILDS INTO THE REGION. THIS...COUPLED WITH A BROKEN DECK OF LOW
STRATUS CLOUDS SHOULD LIMIT THE DIURNAL TEMPERATURE INCREASE
TOMORROW...WITH HIGHS EXPECTED TO ONLY REACH THE MID 50S. THE SURFACE
RIDGE WILL BE ALIGNED DIRECTLY ACROSS THE AREA ON THURSDAY NIGHT...
WITH LIGHT WINDS/CLEARING SKIES AND DEW POINTS IN THE 30-35F RANGE
LEADING TO A COLD MORNING ON FRIDAY...WITH FROST POSSIBLE ACROSS MOST
OF THE AREA. CONDITIONS WILL BEGIN TO CHANGE ONCE AGAIN ON FRIDAY...
AS ANOTHER STRONG UPPER LOW SHIFTS ONSHORE ALONG THE PACIFIC
NORTHWEST COAST. HEIGHT FALLS ASSOCIATED WITH THIS FEATURE WILL
INDUCE A BROAD REGION OF SURFACE CYCLOGENESIS IN THE LEE OF THE
CENTRAL/SOUTHERN ROCKIES...WHICH SHOULD ALLOW A WARM FRONT TO SLOWLY
LIFT NORTHWARD ACROSS CENTRAL MISSISSIPPI AND SOUTHERN ALABAMA
THROUGH THE DAY. THIS WARM FRONT WILL CONTINUE TO LIFT NORTHWARD ON
FRIDAY NIGHT/SATURDAY MORNING...WITH STRONG ELEVATED WARM ADVECTION
PROVIDING THE FORCING FOR WIDESPREAD SHOWER/THUNDERSTORM DEVELOPMENT
NEAR OR JUST NORTHWEST OF THE FORECAST AREA BY DAYBREAK SATURDAY.

THE EXTENDED FORECAST PERIOD WILL LIKELY BEGIN WITH SEVERAL EPISODES
OF SHOWERS AND THUNDERSTORMS FROM SATURDAY THROUGH SUNDAY...AS
GLOBAL MODELS ARE IN FAIRLY GOOD AGREEMENT THAT THE WARM FRONT WILL
REMAIN STALLED SOMEWHERE IN THE VICINITY OF THE TENNESSEE VALLEY...
AS A WEAKENING WAVE OF LOW PRESSURE TRANSLATES EASTWARD FROM THE
OZARKS/ARKLATEX AND ACROSS THE MID-SOUTH. ALTHOUGH IT IS A SAFE BET
TO SAY THAT THE POTENTIAL FOR LOCALLY HEAVY RAINFALL WILL BE HIGH
DURING THIS PERIOD...THE RISK OF SEVERE THUNDERSTORMS IS MUCH MORE
UNCERTAIN AND WILL BE HIGHLY DEPENDENT ON THE EXACT PLACEMENT OF THE
WARM FRONT -- AN IMPORTANT DETAIL WHICH SIMPLY CANNOT BE DETERMINED
AT THIS TIME RANGE. AS THE FRONTAL WAVE CONTINUES TO SHIFT EASTWARD
ACROSS THE SOUTHERN APPALACHIANS ON SUNDAY...INCREASING NORTHERLY
WINDS WILL ALLOW COOLER/DRIER AIR TO BE ADVECTED SOUTHWARD AND THIS
COUPLED WITH INCREASING MID-LEVEL SUBSIDENCE DOWNSTREAM FROM ANOTHER
UPPER LOW DIGGING SOUTHEASTWARD OVER THE FOUR CORNERS REGION SHOULD
LEAD TO DIMINISHING PRECIPITATION CHANCES LATE IN THE DAY. ALTHOUGH
THE ECMWF ENSEMBLE MEAN SOLUTION IS A BIT FASTER THAN THE GFS...BOTH
MODELS AGREE THAT THIS UPPER LOW WILL CROSS THE SOUTHERN ROCKIES ON
SUNDAY NIGHT AND DEEPEN CONSIDERABLY AS IT EMERGES ACROSS THE
SOUTHERN PLAINS ON MONDAY. IT APPEARS THAT A NEW SURFACE LOW WILL
DEVELOP ACROSS THE SOUTHERN PLAINS AS THIS OCCURS...WITH WARM FRONT
EXPECTED TO LIFT NORTHWARD ACROSS THE TENNESSEE VALLEY ONCE AGAIN ON
MONDAY. SHOWER/THUNDERSTORM CHANCES WILL INCREASE FROM THIS POINT
THROUGH TUESDAY...ALTHOUGH GIVEN UNCERTAINTIES ON TRACK OF SURFACE
LOW AND EXTENT OF WARM SECTOR AIR MASS ACROSS THE AREA...WILL ONLY
INCLUDE A SLIGHT CHANCE OF THUNDERSTORMS AT THIS TIME. SURFACE COLD
FRONT SHOULD CLEAR THE AREA AS THE LOW EJECTS NORTHEASTWARD ACROSS
THE OHIO VALLEY ON TUESDAY...WITH DRIER AND COOLER WEATHER
ANTICIPATED ON WEDNESDAY AS ANOTHER SHOT OF CANADIAN AIR COMES INTO
THE REGION.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH ALABAMA AND PORTIONS OF
SOUTHERN MIDDLE TENNESSEE.

.DAY ONE...TONIGHT...

THUNDERSTORMS ARE LIKELY THROUGH THE EVENING ACROSS SOUTHERN MIDDLE
TENNESSEE AND NORTHEAST ALABAMA...WITH A CHANCE OF THUNDERSTORMS
ELSEWHERE ACROSS THE TENNESSEE VALLEY. ISOLATED TORNADOES...DAMAGING
WINDS IN EXCESS OF 60 MPH...AND LARGE HAIL ARE POSSIBLE WITH THE
THUNDERSTORM ACTIVITY ACROSS SOUTHERN MIDDLE TENNESSEE AND EXTREME
NORTHERN ALABAMA...WHERE A TORNADO WATCH IS IN EFFECT UNTIL 10 PM
CDT. THUNDERSTORMS ACROSS THE REMAINDER OF THE AREA WILL BE CAPABLE
OF PRODUCING STRONG WIND GUSTS AND SMALL HAIL. THE THREAT FOR STRONG
TO SEVERE STORMS WILL DIMINISH AFTER 10 PM CDT...AS A COLD FRONT
USHERS A COOLER AND MORE STABLE AIR MASS INTO THE REGION.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY...

THE PROBABILITY FOR WIDESPREAD HAZARDOUS WEATHER IS LOW.

A WARM FRONT WILL MOVE NORTHWARD AND ESSENTIALLY STALL ACROSS THE
AREA EARLY THIS WEEKEND. A WAVE OF LOW PRESSURE WILL MOVE EASTWARD
ALONG THE WARM FRONT ON SATURDAY...BEFORE SHIFTING EAST OF THE REGION
ON SUNDAY...AND WILL GENERATE SEVERAL ROUNDS OF SHOWERS AND
THUNDERSTORMS DURING THE FIRST HALF OF THE WEEKEND. ALTHOUGH THE
PRIMARY THREAT DURING THIS PERIOD WILL BE LOCALLY HEAVY RAINFALL...
SOME THUNDERSTORMS MAY BE CAPABLE OF PRODUCING SEVERE WEATHER...
ESPECIALLY ON SATURDAY AFTERNOON. ANOTHER STORM SYSTEM WILL AFFECT
THE TENNESSEE VALLEY FROM MONDAY NIGHT INTO TUESDAY WITH INCREASING
CHANCES FOR THUNDERSTORMS.

.SPOTTER CALL TO ACTION STATEMENT...

ACTIVATION OF STORM SPOTTERS AND EMERGENCY MANAGEMENT PERSONNEL...IN
SUPPORT OF SEVERE WEATHER OPERATIONS...IS REQUESTED THIS EVENING
