Sorry for not responding earlier. It has continued to be wet in the park for sure, and more on the way today and tomorrow. The creek drainages have recharged some and are flowing pretty well again. Daily high temps are still low (high 40s, then 50s later in the week), so I imagine cliffs will stay pretty wet for awhile.
As JC detailed, the main Pinnacles weather station is on the east side of the park, after the campground turnoff and before the road junction for Bear Gulch / Old Pinnacles trailhead. It is just before a fire road gate along the paved park road.
