Texas Spring-2014

[JDawg512]

I remember that day quite clearly. Was 17 at the time, the school year had ended and I was as Garrison Pool when I began watching the massive cloud billowing up to the north. Even then I knew a pretty good amount about the weather and thought it was strange judging by where the storm was located, generally storms to the north and east do not move towards Austin yet the cloud got larger and larger and it began to form an anvil and darken the sky. I had a strange feeling about it and after noticing some lightning bolts litterally creating a lattice like structure along the outside of the cloud wall which in itself was freaky cause it was a bright sunny day with no clouds overhead and I could still see the lightning. After that I took off walking home and when I got back the tv was already on with live coverage of the tornado right before it moved into Williamson County.

Storms starting to go north and west of DFW. Heck of a time for the KFWS radar to be down

[dhweather]

Heck of a time for the KFWS doppler site to be out of service.

Haha, just said the same thing. Pretty strong wording in the Short Term Forecast just issued at 2:19

SCATTERED THUNDERSTORMS...SOME OF WHICH WILL BE SEVERE...WILL MOVE
EAST AND NORTHEAST AT 20 TO 30 MPH ACROSS PARTS OF NORTH TEXAS
THIS AFTERNOON. THROUGH 430 PM...THE STORMS WILL BE CONCENTRATED
ACROSS COOKE...DENTON...WISE...PARKER AND NORTHERN TARRANT
COUNTIES. HAIL UP TO THE SIZE OF TENNIS BALLS AND WIND GUSTS UP TO
70 MPH CAN BE EXPECTED WITH SOME OF THE SEVERE STORMS THROUGH LATE
AFTERNOON. THE THREAT OF AN ISOLATED TORNADO ALSO EXISTS AND A
TORNADO WATCH HAS BEEN ISSUED FOR MOST OF NORTH AND CENTRAL TEXAS
THROUGH 9 PM.

[TheProfessor]

Wait so they think extreme south central Denton northern Tarrant will be hit? I'm not seeing that on radar.

MESOSCALE DISCUSSION 0262
NWS STORM PREDICTION CENTER NORMAN OK
0146 PM CDT THU APR 03 2014

AREAS AFFECTED...SE OK...NE TX...SW AR

CONCERNING...SEVERE POTENTIAL...WATCH LIKELY

VALID 031846Z - 032015Z

PROBABILITY OF WATCH ISSUANCE...95 PERCENT

SUMMARY...THUNDERSTORMS WERE BEGINNING TO INITIATE TO THE NW OF THE
DALLAS-FT. WORTH METROPLEX AS OF 1830Z. STORMS ARE EXPECTED TO
DEVELOP SOUTHWARD NEAR THE EWD ADVANCING DRYLINE AND MOVE TO THE
E/NE THROUGH THE AFTERNOON. LARGE...DAMAGING HAIL AND STRONG WIND
GUSTS WILL BE THE MAIN THREAT. HOWEVER...A TORNADO OR TWO CAN NOT BE
RULED OUT.

DISCUSSION...CONVECTIVE INITIATION APPEARS TO HAVE OCCURRED JUST TO
THE NW OF DFW NEAR THE DRYLINE. TCU WAS EVIDENT ALONG THE LENGTH OF
THE DRYLINE FROM NEAR ADM IN OKLAHOMA SWD TOWARD SEP. STRONG SFC
HEATING HAS LEAD TO TEMPERATURES IN THE UPPER 70S TO LOW 80S WITH
MID 60S DEWPOINTS...ALLOWING FOR THE WEAKENING OF THE CAP FURTHER TO
THE E ACROSS NE TX AND SE OK. HERE...SBCAPE VALUES APPROACHING 2000
J/KG OR HIGHER COMBINED WITH STEEP MIDLEVEL LAPSE RATES WILL RESULT
IN VIGOROUS THUNDERSTORM DEVELOPMENT WITH AN ATTENDANT THREAT FOR
VERY LARGE...DAMAGING HAIL INTO THE LATE AFTERNOON. DEEP LAYER SHEAR
WILL FAVOR DISCRETE ROTATING SUPERCELL STRUCTURES. LOW LEVEL SHEAR
WILL SUPPORT AT LEAST A LOW-END TORNADO THREAT AS WELL...ESPECIALLY
GIVEN MOIST LOW LEVELS AND DEGREE OF INSTABILITY. AS STORMS MOVE
E/NE UPSCALE GROWTH INTO A QLCS STRUCTURE IS POSSIBLE TOWARD
EVENING.

I'm noticing some winds around the metro are starting to back to a slightly more easterly component. This should contribute to some extra convergence along the dryline to aid in additional development

Don't use the NWS radar. It's stuck at 12:40pm. I'm using WFAA.

[Texas Snowman]

Baseball sized hail on north side of Denton.

[Texas Snowman]

Numerous broken car windows around Denton. Prosper and MCKinney need to look out.

[Texas Snowman]

@TxStormChasers: Multiple car windows destroyed at Texas Woman's University in Denton by massive hail. #txwx #dfwwx

[Texas Snowman]

I saw one photo on Twitter where a hailstone appeared to be softball size.

[Texas Snowman]

Massive hail storm in Denton, many cars with windows blown out. Storm is drawing a bullseye on Prosper and Celina. Haven't seen velocity scans but there appears to be a hook trying to develop near Prosper.

[TheProfessor]

My mom was taking my sister and me back from school. We were driving on 114 and I noticed there were thunder heads building out to my west. Then bam! Some random hail stone fell from the sky. There weren't any cars ahead of us so it wasn't a rock. I wonder what it really was.

[Texas Snowman]

Looks like the Denton Walmart got pounded by the hailstorm.

[Texas Snowman]

@TxStormChasers: 433PM: Supercell with baseball size hail will impact Melissa and Anna along Highway 75 shortly. Weak low level rotation noted. #dfwwx #txwx

I noticed that. I'm surprised the storm isn't Tornado Warned.

[Texas Snowman]

Dr. Forbes also noted the hook "appendage" on the storm now NW of McKinney.

[Texas Snowman]

@TxStormChasers: RT @NWSFortWorth: Large hail core with hail larger than 3" in diameter will pass between Celina and Melissa next few minutes. #txwx #dfwwx

[Ellsey]

I just went outside, and I think this is going to miss me to the north. It looks like it has some good updraft going on though. I'm not in a position where I can see much else though with regards to the possible hook. Twitter has a report of someone at 380 and Custer seeing a lowering though.
