Despite the heat and humidity, subway platforms haven't had quite enough time to transform into microwave ovens, meaning this weekend will be one of the few this season in which you can wait for a train without turning into a puddle. And you'll actually be able to take advantage of that to some extent, as the MTA has announced just 11 changes on subway lines this weekend (and yes, that's fewer than normal). Plus, if you're headed out of town, the LIRR and Metro North are running extra trains out of Penn Station starting this afternoon, so you can (maybe) beat the Montauk rush.

Enjoy, and take note of the changes that are in effect through Tuesday morning:
