If you are an early bird and a space enthusiast, you've got a great chance to view the International Space Station before dawn tomorrow! The ISS will cross the sky from WSW to NE at 4:46 AM EDT. In the middle of its 4 minute trek, it will be almost directly overhead. You'll have to crane your head back about as far as it can go to see this one. Laying down might even be your best option. 

Skies will clear out significantly after midnight, but a few clouds may linger into the early morning hours. Considering the ISS will be moving, you'll catch a glimpse of it over the 4 minute period even if it goes behind a cloud at some point. Temperatures in the middle 60s to low 70s will be ideal for viewing!
