I live in north Texas...I am as nervous as you are.
I'm sure you are with all of the 'fun' that's been had in and around the DFW area this last week. Our forecast for the weekend is more favorable for fires than the previous weeks. We've been under burn bans before but it's not been this dry here since the '50's according to our local weather.
Both Governors' Perry and Henry have made statements about not shooting off fireworks while we're under the ban burn but here in Ok. they haven't closed down the firework stands just have said you can't shoot them off. I would have liked for them to have closed the stands down because you know people are going to buy them and shoot them off.
I know how quickly roofs can catch on fire due to fireworks because the house in Houston I was raised in caught on fire one July 4th.
