Helicity in the RUC is forecasted to increase to 300-400 as the low level jet strengthens. Continue to watch this storm as it tracks to the NE. It has the potential to produce a strong to violent tornado at any time.
It looks very good right now, I'm thinking your right about that one being the one to watch, it really stands out on the radar at the moment.
Currently some friends of mine are on the Des Arc system, will report if anything comes through on the stream.
Best of luck to your friends KWT!

SEL7
URGENT - IMMEDIATE BROADCAST REQUESTED
TORNADO WATCH NUMBER 127
NWS STORM PREDICTION CENTER NORMAN OK
805 PM CDT SAT MAY 1 2010
THE NWS STORM PREDICTION CENTER HAS ISSUED A
TORNADO WATCH FOR PORTIONS OF
EAST CENTRAL AND NORTHEAST ARKANSAS
THE MISSOURI BOOTHEEL
NORTHERN MISSISSIPPI
WESTERN TENNESSEE
EFFECTIVE THIS SATURDAY NIGHT AND SUNDAY MORNING FROM 805 PM
UNTIL 400 AM CDT.
...THIS IS A PARTICULARLY DANGEROUS SITUATION...
DESTRUCTIVE TORNADOES...LARGE HAIL TO 2.5 INCHES IN DIAMETER...
THUNDERSTORM WIND GUSTS TO 70 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 30 MILES NORTH OF DYERSBURG
TENNESSEE TO 35 MILES SOUTHWEST OF OXFORD MISSISSIPPI. FOR A
COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH OUTLINE
UPDATE (WOUS64 KWNS WOU7).
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 125...WW 126...
DISCUSSION...DISCRETE SUPERCELLS NOW MOVING INTO ERN AR WILL PERSIST
OVERNIGHT WHILE MOVING NEWD TOWARD NE AR...WRN TN...AND NW MS...IN
ADVANCE OF AN EJECTING MIDLEVEL TROUGH AND SURFACE LOW. THE
SUPERCELLS WILL MOVE INTO AN ENVIRONMENT OF STRONGER LOW-LEVEL SHEAR
COMPARED TO FARTHER W IN AR...AND VERTICAL SHEAR WILL FURTHER
INCREASE TONIGHT WITH A STRENGTHENING LLJ. MEANWHILE...THE LOW
LEVELS ARE DESTABILIZING ACROSS MS/WRN TN IN THE WAKE OF EARLIER
CONVECTION...SETTING THE STAGE FOR SURFACE-BASED STORMS WELL INTO
THE NIGHT WITHIN A VERY MOIST AND STRONGLY SHEARED ENVIRONMENT. THE
NET RESULT WILL BE THE POTENTIAL FOR SEVERAL LONG-TRACK SUPERCELLS
CAPABLE OF PRODUCING STRONG TORNADOES. FARTHER E/SE INTO TN/NE
MS...THE TORNADO THREAT WILL BE SOMEWHAT LESS THAN AREAS NEAR THE MS
RIVER...THOUGH SUPERCELLS AND COUPLE OF TORNADOES WILL BE POSSIBLE
AS CONVECTION FORMS ALONG THE RETREATING OUTFLOW BOUNDARY.
AVIATION...TORNADOES AND A FEW SEVERE THUNDERSTORMS WITH HAIL
SURFACE AND ALOFT TO 2.5 INCHES. EXTREME TURBULENCE AND SURFACE
WIND GUSTS TO 60 KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO
500. MEAN STORM MOTION VECTOR 24040.

I think they won't be spending too much longer out there now its getting dark, esp given the chances of a rain-wrapped night-time tornado are as relativly high as they are, no point in taking any big risks really....though from what I can tell they are going to head south and try to intercept the cell near Star City, the bigg'un lol....or possibly line up for the cell heading towards Stuttgart.

Thus far the tornadic threat hasn't been quite as bad as was feared, the LLJ that was progged to give 60-80kts of shear thus far seems to be that high...
That being said still some real nice hooks out there, but overall not quite as severe as yesterday upto this point...

Will be interesting to see how this continues in the next few hours, but I'm not sure I'll be around to witness given its already 2.30am here in the Uk!
Still low level shear should build and as you say the best instablity is probably close to the state boundary.

Yep, given the poor season the pool have had, gotta favour Chelsea but we shall see, doesn't always work like that!
The chase team from the UK I'm watching currently heading southwards to intercept the system over De Witt...thus far still seem to have been rather lucky with regards to what could have happened.

Also worth noting a new wave of cells heading into E.AR now which are going to need very close watching over the next 2-3hrs, esp if the low level shear increases...

Yep I think thats quite likely to occur actually.
Also the Star City cell now heading on a track that will take it rather close to Memphis.
