Tornado Observation and Research Crew

Tornado Outbreak, 5 years ago

Posted by: tornadodude, 11:30 PM GMT on November 15, 2010

5 years ago, on this date, an EF3 tornado tore through my county, causing major damage.

The tornado destroyed at least 64 homes and damaged at least 70 more along the US 150 corridor in Washington, Cannelburg and Loogootee. Up to 200 employees were trapped at K&K Industries in Montgomery, but they were all accounted for.

The path of the tornado was 12 miles long, and it was 3/4 mile wide in some spots. Surprisingly, no one was critically injured or killed from this tornado.

...THERE IS A HIGH RISK OF SVR TSTMS ACROSS PORTIONS OF ERN AR...NRN
MS...WRN TN...SERN MO...SRN IL...IN...SWRN OH AND WRN KY...

...THERE IS A MDT RISK OF SVR TSTMS FROM THE LOWER GREAT LAKES AREA
SWWD TO THE LOWER MS VALLEY...

...THERE IS A SLGT RISK OF SVR TSTMS FROM LOWER MI AND THE WRN
SLOPES OF THE APPALACHIANS TO THE WRN GULF COAST...

...E TX/LWR MS VLY NEWD INTO OH VLY/LWR GRT LKS...
SURFACE LOW WAS LOCATED NEAR STL AT 19Z AND MODELS ARE CONSISTENT IN
DEEPENING AND LIFTING THIS SYSTEM RAPIDLY NEWD TO NEAR CHI BY
00Z...AND THEN INTO SRN ONTARIO BY EARLY WEDNESDAY MORNING. A WARM
FRONT EXTENDS EWD FROM THE LOW ACROSS SRN IL/IN INTO OH AND WILL
LIFT NWD TONIGHT...WHILE A TRAILING COLD FRONT...FROM ERN MO SWWD
INTO ERN/SRN TX...RACES EWD THROUGH THE OHIO/TN AND LOWER MS
VALLEYS.

IN THE WARM SECTOR...A RELATIVELY WARM AND MOIST BOUNDARY LAYER IS
PRESENT WITH TEMPERATURES IN THE 70S AND DEWPOINTS IN THE UPPER 50S
TO MID 60S. AN INTENSE SHORTWAVE TROUGH NEAR THE KS/OK BORDER IS
FORECAST TO MOVE NEWD INTO MO THIS EVENING...ACCOMPANIED BY A 110
KT MID LEVEL JET MAX. THIS WILL RESULT IN THE UPPER TROUGH TO BECOME
NEGATIVELY TITLED AND STRENGTHEN THE UPPER LEVEL DIFFLUENCE ACROSS
THE MODERATE AND HIGH RISK AREAS. SCATTERED SEVERE STORMS...SOME
TORNADIC...WERE ONGOING FROM ERN MO/IL SWWD INTO THE LOWER MS VALLEY
AND SHOULD STRENGTHEN THROUGH THE AFTERNOON WITH ADDITIONAL DIABATIC
HEATING AND THE STRENGTHENING DIFFLUENCE ALOFT. VERY STRONG DEEP
LAYER SHEAR AND MLCAPES FROM 1000-1500 J/KG SHOULD FAVOR NUMEROUS
SUPERCELLS WELL INTO THE OVERNIGHT HOURS. THE MOIST BOUNDARY LAYER
AND 1KM SHEAR FROM 25-40 KT INDICATES TORNADOES ARE ALSO
LIKELY...ESPECIALLY FROM NERN AR/WRN TN NEWD INTO THE OH VALLEY THIS
AFTERNOON AND EVENING. THE STRENGTH OF THE FORCING/ENVIRONMENTAL
WINDS...THE QUALITY OF THE BOUNDARY AND VERY STRONG PRESSURE
FALLS...SUGGEST THAT LONG TRACK AND STRONG TORNADOES ARE ALSO LIKELY
THIS AFTERNOON AND EVENING...REFER TO TORNADO
WATCHES...864...865...866 AND 867.

AS THE LOW LIFTS NWD THIS EVENING...THE WARM SECTOR WILL SPREAD INTO
THE NRN HALF OF THE OH VALLEY AND LOWER GREAT LAKES AREA...WITH A
CONTINUED THREAT FOR TORNADIC SUPERCELLS.

OTHER POTENTIALLY TORNADIC SUPERCELLS ARE EXPECTED THIS AFTERNOON
AND TONIGHT ALONG PREFRONTAL CONFLUENCE BANDS AHEAD OF THE COLD
FRONT ACROSS SERN TX/LA/ERN AR AND MS. LONG AND SLIGHTLY CURVED
HODOGRAPHS PLUS LACK OF STRONG LINEAR ASCENT MAY ALSO RESULT IN
SUPERCELLS WITH LONG TRACK TORNADOES. ENVIRONMENT SHOULD ALSO
SUPPORT SMALL SCALE LEWPS/BOWS WITH DAMAGING WINDS AND HAIL.

WHILE THE MS/OH VLY STORMS SHOULD EVENTUALLY CONSOLIDATE INTO
SEVERAL BROKEN SEGMENTS/SQUALL LINES WITH EMBEDDED LEWPS/BOWS
TONIGHT...STRENGTH OF SHEAR AND FORCING SUGGEST THE STORMS MAY
REMAIN SOMEWHAT DISCRETE. AS A RESULT...DAMAGING WINDS ALONG WITH
ISOLATED TORNADOES WILL REACH AS FAR EAST AS THE UPR OH VLY AND THE
WRN SLOPES OF THE CNTRL APPALACHIANS BY 12Z WEDNESDAY.

AREAS AFFECTED...SRN IL...CNTRL/SRN IND...WCNTRL/SWRN OH...NWRN
KY...NWRN TN

CONCERNING...SEVERE THUNDERSTORM POTENTIAL

VALID 151932Z - 152100Z

THERE WILL BE A HIGH POTENTIAL FOR STRONG TORNADOES ACROSS THE OH
VLY REGION FROM SRN IL/NWRN TN EWD INTO CNTRL/SRN IND... WCNTRL/SWRN
OH AND NWRN KY. TORNADO WATCH WILL BE NEEDED DOWNSTREAM OF WWS
865/866 BY 21Z.

A 999 MB LOW WAS LOCATED JUST NE OF KSTL AT 19Z. THE WARM FRONT HAS
JUMPED TO THE I-70 CORRIDOR IN INDIANA AND IS MOVING INTO WCNTRL OH
ATTM. BOUNDARY LAYER HAS BECOME INCREASINGLY UNSTABLE ALONG/S OF
THE FRONT WITH MUCAPE OF 1000-2000 J/KG NOSING NWD INTO THE OH/TN
VLYS. PRESSURE FALLS HAVE ALSO BEEN INCREASING WITHIN THE WARM
SECTOR ACROSS THE OH VLY.

PRE-FRONTAL BAND OF TSTMS INTENSIFIED FROM SRN IL INTO WRN TN AS IT
MOVED INTO THE INSTABILITY AXIS WITH NUMEROUS DISCRETE SUPERCELLS
NOTED. OVERLAY OF 18Z RAOB DATA AND RUC ANALYSIS SHOWS THAT THE
STRONGEST CROSS-OVER BETWEEN SLY H85 WINDS AND THE WSWLY H5 WINDS
EXISTS ACROSS SRN IND/NWRN KY/SWRN OH AT MID-AFTN. LATEST VWP FROM
PAH/EVANSVILLE/WILMINGTON OHIO SHOWS IMPRESSIVE LOW-LEVEL SHEAR
PROFILES /0-1KM SHEAR 35+ KTS/ AS THE BOUNDARY LAYER FLOW BACKS
WITHIN SERN QUADRANT OF THE SFC LOW/PRESSURE FALL AXIS. DISCRETE
SUPERCELLS AND MIXED MODES OF LINE SEGMENTS/ DISCRETE CELLS WILL
REMAIN LIKELY DOWNSTREAM INTO SRN IND...NWRN KY...WRN TN AND
SWRN/WCNTRL OH WITH A HIGH PROBABILITY OF STRONG TORNADOES AND
DAMAGING WIND GUSTS.

URGENT - IMMEDIATE BROADCAST REQUESTED
TORNADO WATCH NUMBER 868...CORRECTED
NWS STORM PREDICTION CENTER NORMAN OK
315 PM EST TUE NOV 15 2005

CORRECTED FOR ADDITION OF PARTICULARLY DANGEROUS WORDING

TORNADO WATCH FOR PORTIONS OF

CENTRAL AND SOUTHERN INDIANA
CENTRAL KENTUCKY
WESTERN OHIO

EFFECTIVE THIS TUESDAY AFTERNOON AND EVENING FROM 315 PM UNTIL
1000 PM EST.

...THIS IS A PARTICULARLY DANGEROUS SITUATION...

DESTRUCTIVE TORNADOES...LARGE HAIL TO 1.5 INCHES IN DIAMETER...
THUNDERSTORM WIND GUSTS TO 80 MPH...AND DANGEROUS LIGHTNING ARE
POSSIBLE IN THESE AREAS.

THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 85 STATUTE MILES
EAST AND WEST OF A LINE FROM 50 MILES NORTH OF MUNCIE INDIANA TO
25 MILES SOUTH SOUTHEAST OF BOWLING GREEN KENTUCKY. FOR A
COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH OUTLINE
UPDATE (WOUS64 KWNS WOU8).

REMEMBER...A TORNADO WATCH MEANS CONDITIONS ARE FAVORABLE FOR
TORNADOES AND SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH AREA.
PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR THREATENING
WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS AND POSSIBLE
WARNINGS.

OTHER WATCH INFORMATION...CONTINUE...WW 864...WW 865...WW 866...WW
867...

DISCUSSION...LINE OF TORNADIC SUPERCELLS OVER WESTERN IND AND
WESTERN KY WILL TRACK EASTWARD THROUGH THE AFTERNOON AND EVENING
TOWARDS WESTERN OH. VERY STRONG LOW LEVEL AND DEEP LAYER SHEAR
PROFILES AND SUFFICIENT INSTABILITY WILL POSE A RISK OF SIGNIFICANT
TORNADOES AND DAMAGING WINDS ACROSS THIS REGION.

AVIATION...TORNADOES AND A FEW SEVERE THUNDERSTORMS WITH HAIL
SURFACE AND ALOFT TO 1.5 INCHES. EXTREME TURBULENCE AND SURFACE
WIND GUSTS TO 70 KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO
450. MEAN STORM MOTION VECTOR 24045.
