Thats an unbelievable sounding.

[cheezyWXguy]

Could someone interpret that sounding for me?

[RL3AO]

Look at the direction of the wind barbs in the center of the image. Surface winds start from the southeast and veers towards the west in height. Its very strong directional wind shear.

lol.

Its now dark and impossible to see any tornadoes in the area. Someone talking about a tornado impact from this monster said before the tornado came, the rain got hotter and hotter...never heard that one. Any explanation?

[CrazyC83]

Indeed, damage looks like EF-4. Hopefully there won't be any fatalities at least...

Note=If anyone has videos or photos,they can be posted at the Sticky 2014 U.S severe season mother thread.

And there is a learning page at NOAA. You have to type "soundings" there

There is already 1 death confirmed from a highway. There was a video shown on the highway I talked about that was very surreal, loud noises and chaos everywhere. Don't know the context but should pop up somewhere.


EDIT: Reports of the tornado still on the ground near Denmark!!

VALID 280143Z - 280245Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH
100...102...103...CONTINUES.

SUMMARY...THE RISK FOR SEVERE THUNDERSTORMS INCLUDING TORNADOES
CONTINUES ACROSS TORNADO WATCHES 100...102...AND 103.

DISCUSSION...THE ONGOING SEVERE THUNDERSTORM AND TORNADO POTENTIAL
ACROSS TORNADO WATCHES 100...102...AND 103 IS EVOLVING IN TWO
REGIMES:

/1/ PRE-FRONTAL SEMI-DISCRETE/DISCRETE SUPERCELLS ARE ADVANCING NEWD
FROM CNTRL AR INTO NERN AR AIDED BY A STRENGTHENING LLJ. UPPER
60S/LOWER 70S SFC-DEWPOINT AIR IS RETREATING NEWD TO SUPPORT
LOWERING OF EFFECTIVE INFLOW LAYERS FOR THE ONGOING CONVECTION.
AND...WITH AROUND 450-600 M2/S2 OF 0-1-KM SRH INDICATED BY RECENT
LZK VWP DATA THAT DEPICT A LONG...LOOPING LOW-LEVEL
HODOGRAPH...TORNADOES -- SOME POSSIBLY SIGNIFICANT -- MAY ACCOMPANY
THIS ACTIVITY. LARGE HAIL AND DAMAGING WINDS WILL ALSO BE POSSIBLE.

/2/ WATER VAPOR LOOPS IMPLY AN ARCING BAND OF ENHANCED MID-LEVEL
ASCENT/MOISTURE OVERTAKING A STALLED BOUNDARY OVER SERN
OK...SUPPORTING THE INITIATION OF CONVECTION. THIS ACTIVITY WILL
LIKELY EXHIBIT QUASI-LINEAR MODES AS IT DEVELOPS ALONG THE FRONT AND
WILL POSE THE RISK FOR DMGG WINDS AND LARGE HAIL. SRX VWP DATA
INDICATE AROUND 25-30 KT OF 0-1-KM BULK SHEAR SUGGESTING SOME
TORNADO THREAT WILL EXIST AS WELL...AS THIS ACTIVITY SPREADS EWD
ACROSS SERN/E-CNTRL OK AND EVENTUALLY INTO PARTS OF WRN AR.

Also, a media report showed a pic of a house that was destroyed in the Vilonia tornado in 2011 that had been re-built, now destroyed once again!!! Insanity.

[cycloneye]

Here is how the Vilonia tornado looked at radar just before it hit.
