They're lowering tornado chances in this round because in all likelihood it'd be a fast-moving and thing squall line. Hail and wind are the main components of this prediction.
The cap is strong over this area, and yesterday it held, which is why storms didn't flare up, not a lot of lift. Today the cap is still strong, but a little distrubance is going to move up along the dry line and if it's strong enough, will provide the lift to break the cap. If it does, storms will fire up quickly.
If current cloud cover holds longer through the day, it'll help, but that's not a guarantee.
My guess again is that most of the severe weather will be Belton and up into Oklahoma.
With that statement, I just put Austin in the bullseye, but I'm stickin' to my story. Little if any rain/storms for us. Whatever happens will happen mid afternoon into about 6-7 p.m.
