I noticed an unusual phenomenon late today: trees dripping with moisture. I sort of half noticed this afternoon, but it really really came to my attention on a walk this evening. Some trees where absolutely dripping, some were unaffected, and the rest occupied the full spectrum in between. At first I thought it was just maples, but then I saw, birch, oak, and Tulip Trees doing it too. It never rained, but the ground under some trees was all wet.
Does anyone have an idea what causes this? Warming up too quickly?
