I'd start with Lost Mines and then move counterclockwise around the park hitting KILLarny and then Nevermore. All three of those are indoors but Nevermore is historically far more impacted by light than the other two.
Definitely wait until dark to hit Witch and Death Water. Both will be severely impacted by daylight. Do also note that both outdoor houses will close for weather so, if it looks like storms could be rolling in later, it may be wise to cut your losses and do the outdoor houses before the sun sets just so you don't miss them if storms do arrive.
Crowds will likely be moderate to heavy assuming good weather. Given the current forecast (much worse Saturday) and the fact that tomorrow is opening night, Howl-O-Scream crowds could possibly be heavier tomorrow vs Saturday. Just a weird possible anomaly to keep in mind. Also note that operations may be abysmal since it's opening weekend.
