Rain overnight- what does it mean for fishing tomorrow ?

[Orey10m]

With the weather being in the 60s tomorrow I am planning on getting out. I was thinking LP or somewhere on the Meramec. But I see now that it's going to be raining some overnight through the region. I have read that you gotta be careful with the Ozark streams because they can rise quickly without warning. 

Well...how do I prepare for that? Do you just adjust which spot you're looking to go to in the first place? Is there anything else you can do?

As in, if the rain/higher water will be coming downstream tomorrow, should I avoid a bigger drainage like the Meramec (around Maramec spring park, cardiac hill etc.)?

And instead go to LP? Or is LP so small that it will be washed out? What are the types of things you guys think about as you plan to fish during and after a little rain?

Thanks for helping me learn!
