It's gonna rain in a few days, and I'm gonna watch the pot plants to see if they respond to the rain outside the same way the outside plants respond. When rain approaches, the foliage will slightly spread out and somewhat droop. The limbs will also lay lower and slump a bit. Not the same kinda droop and slumping that you see in a dying wilting plant. Poor things. Then once the rain is done, the trees and plants all look towards the sky and revel in the freshness. That's how I know when it's gonna rain. The weather forecast is always so bipolar.
