AREAS AFFECTED...PARTS OF ERN OK/WRN-SWRN AR/NERN TX/NRN AND ERN
LA/CENTRAL AND SRN MS

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 222218Z - 222315Z

WW MAY BE NEEDED ACROSS EAST CENTRAL/SERN OK INTO SWRN AR AND SWD TO
NERN TX/NWRN LA. FARTHER SE...ONGOING LARGE CONVECTIVE CLUSTER
ACROSS ERN LA INTO SRN MS WILL CONTINUE TO POSE A THREAT FOR
ISOLATED DAMAGING WET MICROBURST WINDS...BUT GIVEN WEAKER
INSTABILITY...WW FOR THIS REGION IS NOT ANTICIPATED.

...ARKLATEX REGION...
WATER VAPOR IMAGERY SHOWED A WELL DEFINED SRN STREAM SHORT WAVE
TROUGH...CURRENTLY CENTERED OVER FAR E TX/WRN LA...AND EXPECTED TO
TRACK NEWD INTO AR AND WRN LA BY LATE THIS EVENING. ASCENT WITH
THIS FEATURE AND -10 C H5 TEMPERATURES CONTRIBUTING TO STEEP MID
LEVEL LAPSE RATES ACROSS THE ARKLATEX REGION WILL CONTINUE TO
SUPPORT ADDITIONAL TSTM DEVELOPMENT. DEEP SLY WIND FIELDS WILL
RESULT IN STORM MOTION TOWARD THE N...WITH STEEP LOW LEVEL LAPSE
RATES LOCATED INTO SERN OK/SWRN AR WHERE AIR MASS HAS YET TO BE
CONVECTIVELY OVERTURNED SHOULD SUPPORT A THREAT FOR AT LEAST
ISOLATED DAMAGING WINDS. SOME LOW LEVEL HODOGRAPH CURVATURE PER
LATEST WSR-88D VWP DATA AT FORT SMITH AR WOULD ALSO SUPPORT A
POTENTIAL FOR AN ISOLATED TORNADO.

...ERN LA/CENTRAL AND SRN MS...
ONGOING CONVECTIVE CLUSTER ATTENDANT TO MID LEVEL SHORT WAVE TROUGH
APPEARS...PER RADAR IMAGERY...TO HAVE BECOME BETTER ORGANIZED INTO A
EWD MOVING BOW STRUCTURE. DOWNSTREAM AIR MASS ACROSS SERN LA/SRN MS
HAS ALREADY BEEN CONVECTIVE OVERTURNED WHICH SHOULD LIMIT OVERALL
SEVERE WEATHER THREAT TO MAINLY ISOLATED DAMAGING WET MICROBURSTS
AND HEAVY RAINFALL RATES GIVEN PRECIPITABLE WATER VALUES AROUND 1.5
INCHES. FOR ADDITIONAL HEAVY RAINFALL INFORMATION...REFER TO NESDIS
SATELLITE PRECIPITATION ESTIMATE STATEMENTS.

Cell south of McCook, Nebraska showing huge TVS now.

Steve Miller is on the track

[wbug1]

TVS ESE (25 km) of Ogallala, Nebraska.

[CrazyC83]

The tornado reports is up to 27, but we haven't heard much since the area is sparsely populated - most will be in open country.

[wbug1]

Crazy signature or false reading near Ogallala, Nebraska and approaching it. Probably a derecho type event.

[Bunkertor]

After a look at the satlellite i wouldn´t be surprised when thread for severe events would dimish rapidly.
