Light rain is falling before dawn; it should give way to a mostly cloudy, cool day around 65°F, then 53°F tonight. Northeast gusts may reach 23 mph, so the useful combination is a light jacket and a compact umbrella. It is also a UN General Assembly gridlock day: for Midtown, the subway has the stronger thesis.
