Although you want to get her out tonight or tomorrow...
It really all depends on how often she checks her texts.
My current girlfriend texts me about two times a day, shuts her phone off/leaves it somewhere random for the rest of the day, then replies in the morning. So not all women are text Nazi's.
Another thing I noticed was...
"what're you girls up to this weekend?"
That's an AFC way to open a text conversation/conversation in general.
Your an alpha-male of top class, so why would you care they're up to? 
I would just text her with "Hey, let's do something tomorrow
"
Leave it at that, and see what she replies with. Alpha-Males take control of situations.
Remember to never instantly reply back. When you reply quickly all the time/if you're easy to get a hold of, then you appear as an AFC with no life.
IF YOU FIND SHE IS JUST IGNORING YOU, PLEASE READ BELOW:
I once used that exact quote some time ago...
"Hey, let's do something tomorrow
"
I addressed it as an alpha male...
Me: Hey, let's do something tomorrow 
Her: that won't really work (for some unspecified reason she wouldn't really say)
Me: Lame
I then stopped texting her, and waited. Received a text at the very end of the day which was about a paragraph long. She told me she was sorry she could do anything tomorrow, but had time on this day, and that day to do whatever.
If you display yourself as alpha, fun, and attractive. HB 8/9/10's like to play mind games or sh1t tests to see if you're AFC, or the real deal.
If you have the mindset of "fark your ignorance, I know tons of women that are as attractive as you". Women feel that. In my scenario, she felt that when I said "Lame", and didn't reply with anything afterward. Remember, we're not chasing her... We're making her chase you.
Just that fact that I said "Lame", and left it at that for hours on end made her feel as though she was loosing an opportunity, and that I wasn't another AFC that views her as if she sits on some towering untouchable attraction pedestal.
You say she's an HB9, so REMEMBER to neg her quite a bit!!
I find the more attractive women have to be taken care of in the same sort of way you would a girl in her early 20's or fresh out of high school.
