If i'm reading this correctly, has the CAP broken?

[Weatherdude20*]

If i'm reading this correctly, has the CAP broken?

From about Fort Worth westward.

[CrazyC83]

Why isn't anything developing though if the cap has broken and the instability is that great?

[mcallum177]

The NAM and RUC 12 hour precipitation say that TX isn't going to get anything.

[CrazyC83]

Cell now trying to develop near Wichita Falls just as soon as I say that. The cap is slowly trying to break...

[RL3AO]

21z RUC still showing a bit of a cap.

[CrazyC83]

If the models are right I would have at least increased the tornado risk to 10-hatched.

[RL3AO]

Lawton, OK RUC sounding 23z



Impressive veering winds, but thankfully the shear is low.

[mcallum177]

I was just checking through the models...DFW seems to be stuck under this sticky/hot bubble until thursday night.

I've heard 37 tornadoes were produced by the May 10, 2010 Oklahoma outbreak.

I'm sure that figure will fluctuate until all damage surveys are complete.

Nasty, nasty outbreak...sure glad there was no May 3, 1999 style EF-5 that ripped through any areas.
