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

Nashville Metro, TN (KBNA), launched 12:00Z, 3.2 hours before the alert went out and 144 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.

636 AM CST WED JAN 11 2012

.UPDATE...
FOR 12Z TAFS

&&

.DISCUSSION...
/ISSUED 431 AM CST WED JAN 11 2012/
EARLY MORNING ANALYSIS SHOWS A SFC LOW MOVING ACROSS THE SOUTHEAST
AND A VIGOROUS PARENT UPR LOW MOVING ACROSS THE SOUTHERN MISS
VALLEY. THE SFC PRESSURE PATTERN IS COMPLICATED AND INDICATES
PERHAPS A DOUBLE-LOW SITUATION STRETCHING FROM WEST CENTRAL AL INTO
WESTERN TN. MAINLY SHOWERS WITH A FEW EMBEDDED TSRA EXISTED THROUGH
MOST OF THE EVENING AND INTO THE EARLY MORNING HOURS. HOWEVER...THE
UPR LOW HAS GAINED AN INCREASINGLY NEGATIVE TILT AND WATER VAPOR
IMAGERY SHOWS A WELL DEFINED MID/UPR LVL DRY SLOT ROTATING AROUND
THE SOUTHERN/EASTERN PERIPHERY OF THE LOW INTO SOUTHERN AND CENTRAL
AL. STEEPENING LAPSE RATES AND STRENGTHENING UPR LVL DIFFLUENCE HAVE
LEAD TO THE RAPID DEVELOPMENT AND EXPANSION OF TSRA ACTIVITY EARLY
THIS MORNING. DEEP LAYER SHEAR IS REASONABLY IMPRESSIVE...BUT
EFFECTIVE SHEAR IS ESSENTIALLY ZERO WITH PARCELS STILL ELEVATED.
RECENT STORM ORGANIZATION HAS BEEN OBSERVED WITH A FEW EMBEDDED
CELLS...BUT WHILE STORMS REMAIN ELEVATED...THE PROSPECTS FOR SEVERE
WEATHER REMAIN SMALL. RADAR IMAGERY HAS INDICATED THE POSSIBILITY OF
BRIEF MAINLY SMALL HAIL IN A COUPLE OF THE CELLS. HOWEVER...THE MAIN
THREAT FROM THE RAIN AND STORMS THIS MORNING APPEARS TO BE LOCALLY
HEAVY RAINFALL LEADING TO FLASH FLOODING. WHILE NO REPORTS HAVE BEEN
RECEIVED THUS FAR...AND INDICATIONS ARE THAT RAINFALL HAS NOT
EXCEEDED THREAT VALUES...RAINFALL RATES AROUND ONE HALF TO ONE INCH
PER HOUR HAVE BEEN OBSERVED. WILL CONTINUE TO MONITOR FOR THIS AND
OTHER TYPICAL CONVECTIVE THREATS UNTIL THE STORMS PASS THROUGH THE
AREA THIS MORNING.

BASED ON THE LATEST TRENDS...THE MAIN SHIELD OF MDT/HVY RAIN MAY
EXIT CENTRAL AREAS AS EARLY AS 6 AM...AND EASTERN COUNTIES AS EARLY
AS 9 AM. POPS (ALTHOUGH STILL HIGH FOR TODAY) HAVE BEEN TAILORED TO
SHOW LOWER VALUES WEST/HIGHER EAST DURING THE 12Z-00Z
TIMEFRAME...BUT THIS IS MAINLY TO ACCOUNT FOR THE RAINFALL THIS
MORNING. AFTER THE FRONTAL PASSAGE...THE HEAVIER SHOWER ACTIVITY WILL
QUICKLY BEGIN TO WANE...BUT THE ADVANCE OF THE UPR LOW AND ASSOCIATED
LIFT WILL AID IN CONTINUED LGT SHRA AND LGT DRIZZLE THROUGH THE DAY.
BASICALLY...THIS IS SHAPING UP TO BE ANOTHER CLOUDY COOL DAY WITH LOW
CLOUDS...A FEW LGT SHOWERS AND DRIZZLE. THE INITIAL AIRMASS BEHIND
THE FRONT IS PACIFIC AND MODIFIED CONTINENTAL ORIGIN...AND THUS NOT
TOO COLD. TEMPS WILL INITIALLY FALL A LITTLE WITH THE PASSAGE OF THE
FRONT...BUT WILL BE NEARLY STATIONARY THROUGH THE REMAINDER OF THE
DAY WITH VALUES GENERALLY IN THE 50S.

A MUCH COLDER AIRMASS WILL ARRIVE IN THE TENNESSEE VALLEY TOMORROW
AS AN UPR TROUGH QUICKLY DEVELOPS IN THE CENTRAL/EASTERN CONUS. THE
LEADING EDGE OF THIS AIRMASS CAN ALREADY BE SEEN THIS MORNING MOVING
INTO THE NORTHERN PLAINS. TEMPERATURES TOMORROW MORNING WILL LIKELY
BE IN THE 40S AREAWIDE...BUT WILL FALL GRADUALLY THROUGH THE DAY AS
COLD ADVECTION CONTINUES. MOISTURE WITH THE COLD ARCTIC AIRMASS WILL
BE FOLLOWING THE FRONT ON THURSDAY...CHARACTERISTIC OF AN ANAFRONT
SITUATION. VERTICAL MOISTURE/THERMAL PROFILES HAVE BEEN INCREASINGLY
SUPPORTIVE OF DENDRITIC GROWTH AND THE 00Z AND EVEN LATEST 06Z
MODELS HAVE CONTINUES THIS TREND. EXPERIENCE ALSO SUGGESTS THAT THE
MOISTURE COLUMN WILL BE A LITTLE DEEPER THAN MODEL PROGS INDICATE.
AS A RESULT...MENTION OF FZN PRECIP HAS BEEN RETAINED IN THE FCST
PACKAGE FOR THIS MORNING. LIKEWISE...A CONTINUING TREND FOR STEEPER
LOW-LVL LAPSE RATES AND INCREASED FORCING FOR ASCENT WITH THE UPR
LOW HAVE LENT SUPPORT FOR INCREASED FORECAST CONFIDENCE. POPS WERE
RAISED ACCORDINGLY INTO THE CHANCE CATEGORY...BUT FURTHER INCREASES
MAY BE NECESSARY. QPF STILL LOOKS GENERALLY SMALL WITH THIS EVENT
AND WILL LIKELY BE GREATER ON THE HIGHER TERRAIN (AS WILL ANY
SNOWFALL ACCUMULATIONS). IN ADDITION TO THE FALLING TEMPS AND LGT
WINTRY MIX...WINDS WILL BE STRONG OUT OF THE NW ON THURSDAY...WITH
WIND CHILL PROBABLY IN THE 20S DURING THE DAY.

TEMPS WILL LIKELY FALL WELL BELOW FREEZING ON THURS NIGHT...BUT THE
COLDEST NIGHT OF THE PERIOD IS LIKELY TO BE ON SAT UNDER A CLEAR SKY
AND LGT WIND REGIME. LOWS IN THE UPR TEENS TO LOW 20S APPEAR
PROBABLE AT THIS TIME. A BRIEF WARMUP WILL OCCUR LATER ON SATURDAY
AHEAD OF ANOTHER QUICK BUT GLANCING BLOW OF COLD AIR. TEMPS MAY
BE SLIGHTLY COOLER ON SUNDAY BUT THEN ANOTHER REBOUND INTO WARMER
TEMPS IS IN STORE FOR EARLY NEXT WEEK.

MODEL CONSENSUS IS INCREASING FOR ANOTHER FRONT AND CHANCE FOR RAIN
FROM LATE MONDAY INTO TUESDAY. HOWEVER...THIS FRONT WILL BE THE
LEADING EDGE OF A PACIFIC AIRMASS UNDER A DEVELOPING ZONAL FLOW
REGIME AND THUS NOT LIKELY THAT STRONG. LONG WAVE TRENDS AND
TELECONNECTIONS SUGGEST TEMPS NEAR TO ABOVE NORMAL FOR MOST OF NEXT
WEEK.

KDW

&&

.AVIATION...
FOR 12Z TAFS...ALTHOUGH COLD FRONT IS STILL WEST OF BOTH HSV/MSL...
LATEST RADAR DATA SUGGESTS THAT THE THREAT FOR ORGANIZED TSRA
ACTIVITY HAS SHIFTED EASTWARD. WILL MAINTAIN VCTS/CB THRU 11/15Z AT
HSV...AND KEEP VCSH IN FORECAST FOR REMAINDER OF PERIOD -- AND FOR
ENTIRE PERIOD AT MSL -- AS THREAT FOR LIGHT SHRA WILL PERSIST WELL
AFTER FRONTAL PASSAGE. ERRATIC CIGS CURRENTLY REPORTED AT BOTH
AIRPORTS SHOULD EVOLVE INTO A UNIFORMLY BROKEN DECK OF MVFR STRATUS
AFTER FRONTAL PASSAGE...WITH PREVAILING CIGS AROUND 2500 FT AGL
BENEATH OVC050. SURFACE WINDS WILL INCREASE FROM THE SW AS FRONT
PUSHES THRU REGION...WITH 15G25 KNOTS EXPECTED THRU EARLY EVENING.
WINDS WILL DIMINISH SLIGHTLY AND BACK TO SSW LATER THIS EVENING...BUT
SHOULD REMAIN SUFFICIENTLY STRONG TO PREVENT CONCERN FOR REDUCED
VSBY. REGARDLESS...CIGS WILL BEGIN TO LOWER LATE TONIGHT...AND WILL
INDICATE THIS TREND BUT HOLD FORECAST IN THE MVFR RANGE OF 1500-2000
FT AGL.
