The radar

The Maxwell AFB radar (KMXX), 78 km from the middle of the area, began a volume at 02:26 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.

The nearest sounding before it

Birmingham, AL (KBMX), launched 00:00Z, 2.4 hours before the alert went out and 101 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.

555 PM CST SAT JAN 3 2015

.UPDATE...
FOR 00Z AVIATION.

&&

.DISCUSSION...

SEVERAL STORMS CURRENTLY EXHIBITING ROTATING MOVING ACROSS THE
STATE LINE IN AN AREA OF STRONG LOW LEVEL SHEAR WITH 0-1 KM BULK
SHEAR VALES OVER 35 KTS AND 0-1 KM SRH VALUES IN EXCESS OF 300
M2/S2. THESE SHEAR VALUES HAVE INCREASED AS AN UPPER LEVEL TROUGH
IS TAKING ON A NEGATIVE TILT ACROSS THE CENTRAL AND SOUTHERN
PLAINS. MOISTURE HAS GREATLY INCREASED ACROSS THE AREA THIS
AFTERNOON WITH 60 DEGREE DEWPOINTS ALL THE WAY INTO SOUTHERN
TENNESSEE. THESE HIGHER MOISTURE VALUES HAVE PRODUCED SBCAPE
VALUES OF AROUND 250-750 J/KG ACROSS SOUTHERN PORTIONS OF CENTRAL
ALABAMA. THE QUESTION NOW IS HOW FAR ACROSS CENTRAL ALABAMA WILL
THIS AREA OF SEVERE STORMS MOVE. IT APPEARS THAT THE LOW LEVEL JET
WILL BEGIN TO LIFT OUT TO THE NORTHEAST AROUND 03-06Z. IN
ADDITION...THE LOW LEVEL WIND FIELDS WILL VEER TO MORE OF A
SOUTHWESTERLY DIRECTION AND THIS SHOULD LIMIT THE OVERALL LOW
LEVEL SHEAR. THERE IS ALSO A LINE OF SHOWERS AND STORMS STRETCHING
FROM NEAR PELL CITY SOUTHWARD TO NEAR SELMA. THIS AREA OF SHOWERS
AND STORMS COULD ALSO WORK OVER SOME OF THE UNSTABLE AIRMASS
CAUSING THE MAIN LINE OF STORMS TO WEAKEN AS IT MOVES TO THE EAST.
REGARDLESS...0-1 KM BULK SHEAR AND 0-1 KM SRH REMAIN ELEVATED OFF
THE LATEST RUN OF THE RUC AND EXPECT AT LEAST AN EXTENSION OF THE
WATCH EAST A ROW OF COUNTIES OR TWO IS NOT OUT OF THE QUESTION.

.AVIATION...
00Z TAF DISCUSSION.

SHOWERS AND THUNDERSTORMS AHEAD OF AN APPROACHING STORM SYSTEM
WILL AFFECT TCL AT 00Z...THEN THE OTHER TERMINALS WITH THE NEXT
SEVERAL HOURS. BROUGHT A MIX OF IFR CEILINGS....GUSTY
WINDS...THUNDER MENTION AND WIND SHEAR IN THE FORECAST FOR THE
NORTHERN TERMINALS UNTIL 02-04Z. SOUTHERN SITES I DID NOT MENTION
THE WIND SHEAR AS THE STRONGER WINDS LIFT NORTHWARD OVER THE NEXT
FEW HOURS. THE SURFACE WINDS WILL START WITH AN EASTERLY
COMPONENT AND SLOWLY SWING AROUND TO THE SOUTH AND THEN WEST AS
THE STORM SYSTEM MOVES BY.

CEILINGS GO UP AND DOWN AT ALL TERMINALS BETWEEN MVFR AND IFR
THROUGH AROUND 15Z BEFORE RISING INTO MVFR UNDER WESTERLY WINDS.

LOW LEVEL WIND SHEAR WAS ADDED DUE TO THE CHANGE IN WIND DIRECTION
INITIALLY BETWEEN THE SURFACE AND 020. THIS DIRECTIONAL CHANGE
DECREASES WITH TIME BUT THE WINDS SLOWLY INCREASE THE NEXT FEW
HOURS...BEFORE THE WINDS DECREASE AND MOVE OFF TO THE NORTH.

.PREV DISCUSSION...
/ISSUED 229 PM CST SAT JAN 3 2015/

THERE'S SEVERAL WEATHER IMPACTS TO DISCUSS OVER THE NEXT SEVEN
DAYS SO LET'S GET RIGHT TO IT. THE FIRST OF THESE IMPACTS IS
LITERALLY RIGHT ON OUR DOORSTEP. AN UPPER LOW IS SPINNING OVER THE
TEXAS PANHANDLE WITH THE ASSOCIATED SFC LOW TRACKING NORTHEAST
INTO ILLINOIS. THE TRAILING COLD FRONT CURRENTLY STRETCHES
SOUTHWARD FROM THE LOW CENTER INTO CENTRAL LA. THE WARM FRONT
CONTINUES TO PUSH NORTHWARD ACROSS AL WITH DEW POINTS ALREADY IN
THE LOW/MID 60S ACROSS THE SOUTHWESTERN HALF OF THE STATE AS
MOISTURE SURGES NORTHWARD FROM THE GULF. A LINE OF STORMS IS
ALREADY TAKING SHAPE JUST EAST OF THE MS RIVER WITH SCATTERED
THUNDERSTORMS DEVELOPING OUT AHEAD OF THE LINE ACROSS SOUTH MS
JUST TO EAST OF WHAT APPEARS TO BE A MESOLOW. THE SQUALL LINE
WILL CONTINUE TO TRACK EASTWARD ACROSS MS THIS AFTERNOON AND IS
SET TO ENTER OUR WESTERN COUNTIES AFTER 4PM...WITH SOME OF THE
INDIVIDUAL STORMS POSSIBLY ENTERING A BIT SOONER.

AS FOR THE IMPACTS EXPECTED HERE ACROSS CENTRAL ALABAMA WITH THIS
SYSTEM...THEY HAVEN'T CHANGED MUCH. SPC STILL HAS THE WESTERN HALF
OF AL OUTLOOKED IN A SLIGHT RISK AND THIS IS WHERE WE WILL
CONTINUE TO HIGHLIGHT THE THREAT FOR ISOLATED SEVERE STORMS. SHEAR
WILL BE SUFFICIENT FOR ORGANIZED THUNDERSTORMS AND ROTATING
UPDRAFTS...AND EVEN WITH CONTINUED CLOUD COVER INSTABILITIES
SHOULD BE IN THE 500-1000 J/KG RANGE AT LEAST IN THE SW PORTION OF
THE CWA. EXPECT THE SYSTEM TO MAINTAIN INTENSITY AS IT ENTERS
WESTERN AL LATE THIS AFTERNOON FOLLOWED BY A WEAKENING TREND AS IT
PROGRESSES EASTWARD ACROSS THE STATE...MAINLY DUE TO WANING
INSTABILITIES AND WEAKENING UPPER LEVEL FORCING. DAMAGING WIND
GUSTS WILL BE THE MAIN THREAT...BUT AN ISOLATED TORNADO WILL ALSO
BE POSSIBLE. THE MAIN TIME FRAME OF CONCERN REMAINS 4PM UNTIL
MIDNIGHT TONIGHT. BEYOND MIDNIGHT EXPECT THE SYSTEM TO WEAKEN WITH
A LINE IF SHOWERS AND SUB-SEVERE STORMS TO CONTINUE TO PUSH EAST
ACROSS EASTERN AL THRU SUNDAY MORNING.

ANOTHER POTENTIAL THREAT FROM THIS SYSTEM WILL BE LOCALIZED FLASH
FLOODING. GROUND CONDITIONS REMAIN FAIRLY SATURATED AFTER THE
HEAVY RAINS OF THE PAST TWO WEEKS...AND SEVERAL AREA RIVERS REMAIN
SLIGHTLY ELEVATED. WITH AN ADDITIONAL 1-2 INCHES OF RAIN FORECAST
FROM NOW THROUGH SUNDAY MORNING A FLASH FLOOD WATCH REMAINS IN
EFFECT FOR AREAS GENERALLY ALONG/NORTH OF A LINE FROM DEMOPOLIS TO
ANNISTON. MINOR RIVER FLOODING IS ALSO POSSIBLE...MOST NOTABLY
ALONG PORTIONS OF THE TOMBIGBEE AND BLACK WARRIOR RIVERS.

ONCE THIS SYSTEM FINALLY EXITS TO THE EAST BY SUNDAY AFTERNOON
WE'LL SEE A MUCH NEEDED PERIOD OF DRY WEATHER THAT WILL PERSIST
THRU NEXT WEEK. ALTHOUGH IT WILL BE DRY...IT WON'T BE WITHOUT
IMPACT. A DRY COLD FRONT WILL CROSS THE AREA ON TUESDAY WHICH WILL
BE FOLLOWED BY AN ARCTIC AIR MASS. THIS WILL BE THE COLDEST TEMPS
WE'VE SEEN THIS WINTER SEASON. TEMPS WEDNESDAY NIGHT WILL BOTTOM
OUT IN THE TEENS AND 20S...WITH A HARD FREEZE LIKELY ACROSS THE
NORTHERN PORTIONS OF CENTRAL ALABAMA. NORTHERLY WINDS OF AROUND 10
MPH WILL CREATE WIND CHILLS IN THE SINGLE DIGITS...OR PERHAPS EVEN
BELOW ZERO IN SOME LOCATIONS. HIGHS ON THU WILL STRUGGLE TO REACH
THE FREEZING MARK IN THE NORTH.
