★★ An indecisive follow-up to the sweeping storms of the night before. Morning was humid gray. A couple crowded into the niche between the turnstile fence and the MetroCard machines to kiss. The air was close and still. Paulownia leaves sprouting from a traffic-calming planting bed found enough breeze to wiggle on, and then a puff of wind delivered a raindrop just below the corner of the mouth. That was all the rain, for a while. The gray became glaring, up on the roof. White edging showed, and a little blue, until it was too bright to read in. Then it darkened and dimmed again. A shower passed, carrying a harbor smell to the Upper West Side, and another arrived. Both were unspectacular.
