Tornado Outbreak April 29-May 2, HIGH RISK AR, TN, MS

[Texas Snowman]

Looks like a hook echo (to my unofficial and untrained eye) developing on the storm entering Texarkana...

AREAS AFFECTED...MIDDLE/ERN TN

CONCERNING...TORNADO WATCH 126...

VALID 020007Z - 020100Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 126 CONTINUES.

THREAT OF DMGG WINDS AND ISOLD TORNADOES PERSISTS FOR PORTIONS OF
MIDDLE/ERN TN.

ANTICYCLONIC FLOW ALOFT NOTED ON WV IMAGERY IS INDICATIVE OF
SUBSIDENCE OVER THE WW AREA...WHICH SEEMS TO BE REFLECTED IN RECENT
DISORGANIZED STORM STRUCTURES ON RADAR IMAGERY. DESPITE
THIS...HIGHER THETA-E AIR MASS TO THE S WILL CONTINUE TO SUPPORT
STORM DEVELOPMENT...WITH WIND PROFILES FAVORING SMALL BOWING
SEGMENTS AND OCCASIONALLY ROTATING STORMS. NEARLY W-E ORIENTED
BOUNDARY EXTENDING THROUGH SRN TN WILL LIKELY REMAIN AREA OF FOCUS
FOR NEW STORM DEVELOPMENT OR INTENSIFICATION OF ANY STORMS THAT CAN
FORM...AS LOW LEVEL VORTICITY WILL BE ENHANCED ALONG THE BOUNDARY.

Thanks KWT. I'll check tomorrow morning. Back to the outbreak.

[CrazyC83]

Pine Bluff - a fairly large community - is in the DIRECT line of a tornado right now.

AREAS AFFECTED...PARTS OF CENTRAL AND SRN AR/NRN LA/NERN TX

CONCERNING...TORNADO WATCH 125...

VALID 020011Z - 020115Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 125 CONTINUES.

WW 125 HAS BEEN LOCALLY EXTENDED IN AREA /ONE TIER OF COUNTIES/ FROM
WEST CENTRAL-NRN AR.

TRENDS IN OBJECTIVE ANALYSES INDICATED THE AIR MASS FROM E TX/LOWER
MS VALLEY INTO AR/WRN TN HAS CONTINUED TO DESTABILIZE WITH MLCAPE
2000-2500 J/KG ACROSS NERN TX TO SRN AR...WHILE DESTABILIZATION IS
ALSO OCCURRING WITH NWD EXTENT ALONG AND JUST N OF THIS WATCH.
EFFECTIVE BULK SHEAR REMAINS MORE THAN SUFFICIENT FOR ORGANIZED
STORMS WITH MOST ACTIVITY TENDING TO TRACK NWD...WHILE A FEW STORMS
HAVE BEEN ABLE TO TRACK NEWD RESULTING IN A GREATER TORNADO THREAT.

FARTHER SSW INTO EAST CENTRAL-SERN TX...LARGE SCALE ASCENT SPREADING
INTO THIS REGION WITH AN INCREASE IN LOW LEVEL CONVERGENCE ALONG THE
SSWWD TRAILING COLD FRONT SHOULD SUPPORT ADDITIONAL TSTM
DEVELOPMENT. LIMITED AREAL COVERAGE OF STRONGER ACTIVITY JUST TO
THE SSW OF WW 125 SHOULD PRECLUDE THE NEED FOR A NEW WATCH OVER
PARTS OF EAST CENTRAL-SERN TX.

Very well defined radar hook echo is moving towards SW edge of Pine Bluff...

[Bunkertor]

Jefferson County debris ball ? Anyone an idea ?

[wx247]

I hope that storm near Pine Bluff doesn't produce a tornado... that is heading right toward town.

[brunota2003]

I'm going to be honest...I am not too impressed with the SRV images for these tornado warnings (except the Pine Bluff one, and the one well south of Pine Bluff). Granted, I have to look at the NWS radar, instead of my GRLevel2Analyst (due to dial up like internet).

[CrazyC83]

KARK calling Pine Bluff a "tornado emergency", totally unofficial at this point though since NWS Little Rock hasn't said that yet.

[KWT]

Yeah it does look decent, another one that has caught my eye is heading close to Conway again....

[btangy]

The most dangerous storm is passing very near Warren, AR. Very tight couplet. Far from the KLZK radar so hard to tell if this strong circulation is extended to the ground. I think this storm has potential to be a long tracker since it's on the S end of the line, in the most unstable airmass and beginning to tap into some very high helicity (spin in the lower atmosphere). The helicity shoots up sharply during the next couple hours over SE AR, so the tornado potential (especially strong ones) will continue to increase.

[Texas Snowman]

THV2.com reporting ham radio ops indicating a tornado on the ground near Warren I think (?)

[MGC]

Things are not looking good for the people in Ark. Must have half a dozen tornado warning last I looked. The cell near Pine Bluff looks like business.....MGC

I'm glad I'm not the only one who noticed that storm. That one looks best to me, with Pine Bluff being second. The rest I could not really see any rotation in on the NWS radar page showing the SRV winds. The radar images I can see hooks on though.

[wx247]

Funnel cloud 3 miles SE of Pine Bluff per law enforcement.

[KWT]

Interesting spot on the Warren storm, the hook is certainly evident though it looks anti-cyclonic, at least it seems that way??

[Texas Snowman]

Humnoke in path of a hook echo...spotter indicating a funnel cloud alternately lowering and rising (according to KARK).
