AREAS AFFECTED...PORTIONS OF AR...ERN OK...NRN LA...NERN TX

CONCERNING...TORNADO WATCH 100...97...

VALID 272311Z - 280015Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 100...97...CONTINUES.

SUMMARY...THE TORNADO RISK CONTINUES ACROSS TORNADO WATCHES 97 AND
100. THE GREATEST SHORT-TERM TORNADO THREAT EXISTS ACROSS W-CNTRL
AR...WHERE SIGNIFICANT TORNADOES WILL BE POSSIBLE.

DISCUSSION...DISCRETE/SEMI-DISCRETE SUPERCELLS DEVELOPING IN A ZONE
OF LOW-LEVEL CONFLUENCE FROM THE ARKLATEX NEWD WILL CONTINUE TO
MATURE AS MID-LEVEL FLOW STEERS THIS ACTIVITY NEWD...WHILE
ADDITIONAL CONVECTION SHIFTS E FROM SERN OK. THIS ACTIVITY WILL
INTERACT WITH A NWD-RETREATING WARM FRONTAL ZONE CURRENTLY ARCING
FROM E OF FSM TO S OF HOT AND S OF LIT. THIS FRONT WILL CONTINUE TO
BE DRIVEN NWD IN RESPONSE TO 2-HRLY PRESSURE FALLS OF 2.0-3.5 MB TO
ITS NORTH. NEAR THE FRONT...STRONG LOW-LEVEL SHEAR SAMPLED BY THE
LITTLE ROCK VWP SUPPORTING 0-1-KM SRH OF 400-500 M2/S2 WILL FOCUS
THE GREATEST SHORT-TERM RISK FOR TORNADOES -- SOME POSSIBLY
SIGNIFICANT -- ACROSS W-CNTRL AR. WHILE STORMS CROSSING THE WARM
FRONT WILL HAVE A TENDENCY OF INGESTING MORE STABLE INFLOW...THE
GRADUAL RETREAT OF THE FRONT ALLOW THIS RISK TO EXTEND NE WITH TIME.
ALSO...A LONE SUPERCELL STORM CROSSING VAN ZANDT COUNTY TX WILL
CONTINUE TO ADVANCE EWD WITHIN AN INCREASINGLY FAVORABLE VERTICAL
SHEAR PROFILE FOR TORNADOES IN NERN TX.

NWS STORM PREDICTION CENTER NORMAN OK
0610 PM CDT SUN APR 27 2014

AREAS AFFECTED...SW MO

CONCERNING...SEVERE POTENTIAL...TORNADO WATCH LIKELY

VALID 272310Z - 280045Z

PROBABILITY OF WATCH ISSUANCE...95 PERCENT

SUMMARY...SEVERAL SUPERCELL STORMS...SOME WITH A HISTORY OF
PRODUCING TORNADOES...WILL CONTINUE TO TRACK E/NE ACROSS SW MO. A
NEW TORNADO WATCH WILL BE NEEDED WITHIN THE NEXT HOUR.

DISCUSSION...A NARROW CORRIDOR ACROSS SW MO WILL CONTINUE TO SUPPORT
ONGOING SUPERCELL THUNDERSTORMS...SOME WITH A HISTORY OF PRODUCING
TORNADOES NEAR THE MO/KS STATE LINE. THE AXIS OF GREATEST TORNADO
POTENTIAL WILL EXTEND FROM NEAR THE KANSAS CITY METRO AREA SEWD TO
JUST EAST OF SPRINGFIELD MO. HERE...THE BOUNDARY LAYER HAS RECOVERED
ENOUGH TO SUPPORT MUCAPE VALUES APPROACHING 2000 J/KG. THE 88-D VAD
WIND PROFILE FROM KSFG SHOWED BACKED LOW LEVEL FLOW WITH A FAVORABLE
CYCLONICALLY CURVED HODOGRAPH WITH O-1 KM SRH APPROACHING 400 M2/S2.


FURTHER E TOWARD CENTRAL AND S-CENTRAL MO THE TORNADO THREAT WILL
NOT BE ZERO BUT WILL DECLINE DUE AS EARLIER CONVECTION HAS LEAD TO A
COOLER AND MORE STABLE BOUNDARY LAYER. HOWEVER...LOW LEVEL SHEAR
WILL REMAIN SUFFICIENT FOR ROTATING STORMS. FURTHERMORE...CONVECTION
MAY BEGIN TO GROW UPSCALE AS IT MOVES INTO THIS REGION.

Official: 2 dead after tornado hits Quapaw, Oklahoma; extent of damage still unknown http://www.wwltv.com/news/national/256914361.html …

[EF-5bigj]

I'll be watching the sky's on Mon but the threat seems father north. Prayers for those affected today

[Alyono]

no warning was issued for that deadly tornado

Wonder how that happens these days

[apocalypt-flyer]

I think a warning was issued for extreme SW Missouri for that cell but it obviously turned tornadic from the get-go.

Apparently the fire station was destroyed and the north-side of Quapaw suffered quite some damage.

[WeatherGuesser]

Looks like it's the same cell that triggered the warning for south of Joplin.
