1248 PM CDT SUN APR 27 2014
AREAS AFFECTED...NERN CO...FAR SW NEB
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 271748Z - 272015Z
PROBABILITY OF WATCH ISSUANCE...5 PERCENT
SUMMARY...ISOLATED BRIEF TORNADOES WILL BE POSSIBLE WITH A BAND OF
CONVECTION ON THE CUSP OF THE LOW-LEVEL DRY SLOT. WW ISSUANCE IS NOT
ANTICIPATED.
DISCUSSION...CONVECTION HAS RECENTLY INCREASED IN A NARROW BAND
ALONG THE LEADING EDGE OF THE DRY SLOT ACROSS NERN CO...COINCIDENT
WITH A NARROW AXIS OF 500 J/KG SBCAPE NOTED BY RECENT OBJECTIVE
MESOANALYSIS. DEEP-LAYER WIND PROFILES WILL NOT FAVOR ORGANIZED
STORM STRUCTURES...BUT STEEP LOW-LEVEL LAPSE RATES COMBINED WITH
RICH SURFACE VORTICITY IN THE VICINITY OF THE SFC LOW WILL RESULT IN
A THREAT OF ISOLATED BRIEF TORNADOES THROUGH THE AFTERNOON.

1225 PM CDT SUN APR 27 2014
AREAS AFFECTED...ERN OK...NERN TX THROUGH WRN AND CNTRL ARKANSAS
CONCERNING...SEVERE POTENTIAL...WATCH LIKELY
VALID 271725Z - 271930Z
PROBABILITY OF WATCH ISSUANCE...95 PERCENT
SUMMARY...THE ATMOSPHERE IS EXPECTED TO BECOME INCREASINGLY
FAVORABLE FOR LONG TRACK SUPERCELLS CAPABLE OF TORNADOES...A FEW OF
WHICH COULD BE STRONG BY MID-LATE AFTERNOON. LARGE HAIL AND DAMAGING
WIND WILL ALSO BECOME LIKELY WITH THE STRONGER STORMS. MESOSCALE AND
CONVECTIVE TRENDS WILL CONTINUE TO BE MONITORED...AND A TORNADO
WATCH WILL LIKELY BE NEEDED BY 19Z-20Z.
DISCUSSION...EARLY THIS AFTERNOON A PACIFIC COLD FRONT EXTENDS FROM
ERN KS SWD THROUGH CNTRL OK INTO NCNTRL TX. A WARM FRONT WAS LOCATED
FROM NRN MS THROUGH CNTRL ARKANSAS. THE WARM SECTOR BETWEEN THESE
BOUNDARIES CONTINUES TO DESTABILIZE AS A STRONG LLJ ADVECTS UPPER
60S DEWPOINTS NWD BENEATH STEEP LAPSE RATES. HOWEVER...THE RATE OF
BOUNDARY LAYER DESTABILIZATION HAS BEEN SLOWED BY MULTILAYER CLOUDS
INCLUDING STRATUS AND CONVECTIVE DEBRIS. LATEST VISIBLE IMAGERY DOES
SHOW NUMEROUS CLOUD BREAKS...AND THE STRATUS DECK OVER CENTRAL
ARKANSAS MAY EVENTUALLY ERODE FROM THE SOUTH. AN AXIS OF 1500-2500
J/KG MLCAPE WILL DEVELOP ACROSS THIS REGION THIS AFTERNOON.
A PRE-FRONTAL BELT OF ASCENT WITH WHAT APPEARS TO BE AN EWD
PROPAGATING GRAVITY WAVE CONTINUES FROM WRN ARKANSAS THROUGH NWRN
TX. MEANWHILE AN UPPER JET STREAK ROTATING THROUGH BASE OF THE UPPER
TROUGH WILL SHIFT EWD THROUGH NRN TX INTO THE LOWER MS VALLEY.
FORCING FOR ASCENT ASSOCIATED WITH THESE FEATURES AS WELL AS
BOUNDARY LAYER WARMING SHOULD EVENTUALLY WEAKEN THE CAP SUFFICIENTLY
FOR SURFACE BASED THUNDERSTORM DEVELOPMENT WITHIN AXIS OF
PRE-FRONTAL CONFLUENCE IN WARM SECTOR...AS WELL AS ALONG THE PACIFIC
FRONT. STRENGTHENING WIND PROFILES ASSOCIATED WITH THE APPROACHING
UPPER JET AND FAVORABLE LOW-LEVEL HODOGRAPHS WILL SUPPORT SUPERCELLS
WITH LOW-LEVEL MESOCYCLONES CAPABLE OF PRODUCING TORNADOES AND LARGE
HAIL. THE 0-1 KM HODOGRAPHS APPEAR MAXIMIZED ACROSS CNTRL AR WHERE
LOW-LEVEL WINDS REMAIN BACKED IN VICINITY OF THE WARM FRONT THAT IS
CURRENTLY BEING REINFORCED BY ELEVATED CONVECTION.

URGENT - IMMEDIATE BROADCAST REQUESTED
TORNADO WATCH NUMBER 97
NWS STORM PREDICTION CENTER NORMAN OK
150 PM CDT SUN APR 27 2014
THE NWS STORM PREDICTION CENTER HAS ISSUED A
* TORNADO WATCH FOR PORTIONS OF
MUCH OF CENTRAL AND WESTERN ARKANSAS
EXTREME NORTHERN LOUISIANA
EASTERN OKLAHOMA
NORTHEAST TEXAS
* EFFECTIVE THIS SUNDAY AFTERNOON AND EVENING FROM 150 PM UNTIL
900 PM CDT.
* PRIMARY THREATS INCLUDE...
SEVERAL TORNADOES AND A COUPLE INTENSE TORNADOES LIKELY
WIDESPREAD LARGE HAIL AND ISOLATED VERY LARGE HAIL EVENTS TO 2.5
INCHES IN DIAMETER LIKELY
SCATTERED DAMAGING WINDS AND ISOLATED SIGNIFICANT GUSTS TO 80
MPH POSSIBLE
THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 105 STATUTE
MILES EAST AND WEST OF A LINE FROM 15 MILES NORTH OF HARRISON
ARKANSAS TO 60 MILES SOUTH SOUTHEAST OF TEXARKANA ARKANSAS. FOR
A COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH
OUTLINE UPDATE (WOUS64 KWNS WOU7).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
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 94...WW 95...WW 96...
DISCUSSION...COMPLICATED SCENARIO EARLY THIS AFTERNOON...BUT THREAT
FOR SURFACE-BASED STORM DEVELOPMENT WILL INCREASE IN THE NEXT FEW
HOURS LONG THE SURFACE WIND SHIFT IN ERN OK/NE TX...AND NEAR AN
OUTFLOW BOUNDARY ACROSS CENTRAL AR. THE STORM ENVIRONMENT WILL
BECOME MORE FAVORABLE FOR SUPERCELLS WITH TIME...AND WILL SUPPORT A
STRONG TORNADO RISK BY LATE AFTERNOON INTO THIS EVENING...ESPECIALLY
NEAR THE RESIDUAL OUTFLOW BOUNDARY IN AR. OTHERWISE...THE MORE
INTENSE SUPERCELLS WILL BE CAPABLE OF PRODUCING VERY LARGE HAIL AND
DAMAGING WINDS.
AVIATION...TORNADOES AND A FEW SEVERE THUNDERSTORMS WITH HAIL
SURFACE AND ALOFT TO 2.5 INCHES. EXTREME TURBULENCE AND SURFACE
WIND GUSTS TO 70 KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO

AREAS AFFECTED...MOST OF MO...CNTRL IA...FAR WRN IL
CONCERNING...TORNADO WATCH 95...
VALID 271859Z - 272000Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 95 CONTINUES.
SUMMARY...THE THREAT FOR DAMAGING WINDS AND ISOLATED TORNADOES
CONTINUES ACROSS TORNADO WATCH 95...ESPECIALLY ACROSS CNTRL/NRN MO
WHERE SOME HEATING HAS OCCURRED. DOWNSTREAM WATCH ISSUANCE WILL
LIKELY BE REQUIRED INTO ERN MO/WRN IL AND PERHAPS SERN IA BEFORE
20Z.
DISCUSSION...AS OF 1830Z...AN EXTENSIVE QLCS RUNS FROM WRN IA INTO
W-CNTRL MO...WITH DAMAGE AND A POSSIBLE TORNADO NOTED RECENTLY NEAR
ODESSA MISSOURI. SOME CLEARING AND DESTABILIZATION HAS OCCURRED
AHEAD OF THE LINE ACROSS ERN MO...ALLOWING MLCAPE TO RISE TO
1000-1500 J/KG PER RECENT OBJECTIVE MESOANALYSIS. WITH SUFFICIENT
EFFECTIVE SHEAR IN PLACE...THE SRN PART OF THE QLCS IS LIKELY TO
MAINTAIN ITSELF AS IT HEADS INTO ERN MO/WRN IL...WHERE ANOTHER WATCH
ISSUANCE MAY BECOME NECESSARY BY 20Z. GIVEN THE WELL-ESTABLISHED
LINEAR MODE...DAMAGING WINDS WILL BE THE PRIMARY THREAT...THOUGH
ISOLATED TORNADOES WILL REMAIN POSSIBLE THIS AFTERNOON GIVEN THAT
LOW-LEVEL WIND PROFILES MAY SLOWLY IMPROVE WITH TIME AHEAD OF THE
LINE.
IN THE NORTHERN PART OF WW 95 ACROSS CNTRL/ERN IA...CLOUDINESS AND
WIDESPREAD CONVECTION HAS LIMITED DESTABILIZATION...BUT SOME
CLEARING/WARMING ACROSS ERN IA MAY HELP TO SUSTAIN A DAMAGING WIND
RISK IN THIS AREA TO THE EAST OF THE CURRENT WATCH.
ACROSS WRN MO...COOL AND STABLE CONDITIONS ARE WIDESPREAD IN THE
WAKE OF THE QLCS. SOME REGENERATION OF CONVECTION HAS BEEN NOTED
ACROSS SWRN MO...WHERE STEEP UPSTREAM LAPSE RATES WILL SUPPORT A
LOCALLY SEVERE HAIL RISK IN THE NEAR TERM. WHILE THE MAIN PACIFIC
FRONT IS STILL WELL TO THE WEST...IT WILL LIKELY TAKE SEVERAL HOURS
FOR SIGNIFICANT AIRMASS RECOVERY TO OCCUR IN THE WAKE OF THE QLCS.

MESOSCALE DISCUSSION 0424
NWS STORM PREDICTION CENTER NORMAN OK
0401 PM CDT SUN APR 27 2014
AREAS AFFECTED...NCNTRL MS
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 272101Z - 272230Z
PROBABILITY OF WATCH ISSUANCE...40 PERCENT
SUMMARY...STORMS MAY DEVELOP ACROSS A PORTION OF NCNTRL MS THIS
AFTERNOON AND EARLY EVENING. PRIMARY THREATS WILL BE LARGE HAIL AND
PERHAPS A COUPLE TORNADOES. MESOSCALE AND CONVECTIVE TRENDS WILL
CONTINUE TO BE MONITORED FOR A POSSIBLE WW.
DISCUSSION...LATE THIS AFTERNOON A CONVECTIVELY REINFORCED
QUASISTATIONARY FRONT EXTENDS ACROSS NRN MS. THE WARM SECTOR SOUTH
OF THIS BOUNDARY HAS BECOME QUITE UNSTABLE WITH UPPER 60S DEWPOINTS
AND DIABATIC WARMING CONTRIBUTING TO 1500-2000 J/KG MLCAPE. A STORM
HAS INITIATED ALONG BOUNDARY NEAR THE NWRN MS AND ARKANSAS BORDER.
ENEWD STORM MOTION SUGGESTS IT SHOULD CROSS INTO THE COOL SECTOR.
HOWEVER...IF THE STORM BEGINS TO TURN MORE RIGHT IT MAY REMAIN
SURFACE BASED AS IT MOVES ALONG THE BOUNDARY WHERE LARGE LOW-LEVEL
HODOGRAPHS AND 50 KT EFFECTIVE SHEAR WOULD SUPPORT A CONDITIONAL
THREAT FOR ISOLATED TORNADOES. OTHERWISE LARGE HAIL AND DAMAGING
WIND WILL BE LIKELY.
