AREAS AFFECTED...ERN OK THROUGH WRN AR AND NERN TX

CONCERNING...SEVERE POTENTIAL...WATCH LIKELY

VALID 250042Z - 250145Z

SEVERE THREAT IS EXPECTED TO DEVELOP TOWARD WRN AR AND NERN TX
DURING THE EVENING. A NEW TORNADO WATCH WILL LIKELY BE NEEDED FOR
ERN OK...WRN AR AND NERN TX WITHIN THE HOUR.

LATEST OBJECTIVE ANALYSIS INDICATES THE ATMOSPHERE REMAINS
MODERATELY UNSTABLE FROM ERN OK INTO WRN AR AND NERN TX. ONSET OF
NOCTURNAL COOLING WILL CONTRIBUTE TO AT LEAST MODEST BOUNDARY LAYER
STABILIZATION AND INCREASING CONVECTIVE INHIBITION. HOWEVER...LLJ
WILL SHIFT EWD WITH TIME...AND DEEPER LAYER FORCING ASSOCIATED WITH
EJECTING VORT MAX SHOULD HELP TO SUSTAIN STORMS WELL INTO THE
EVENING. LARGE HODOGRAPHS AND EFFECTIVE SHEAR AND 2000 J/KG MLCAPE
WILL CONTINUE TO SUPPORT SUPERCELLS AND BOWING SEGMENTS WITH A
THREAT FOR ISOLATED TORNADOES...LARGE HAIL AND DAMAGING WIND. THE
MORE DISCRETE STORMS ARE EXPECTED TO PERSIST ACROSS SERN OK INTO
NERN TX WITH MIXED MODES LIKELY TO PERSIST FARTHER NORTH.

Nasty hook echo or tornado looks to be taking direct aim on Dallas as it drops ESE. Let's hope there is no tornado on the ground.

[CrazyC83]

Not sure I agree with this. I would have kept NE Texas and SE Oklahoma at a high risk.
