The biggest full Moon of the summer rises Sunday evening, August 10th around 7:30 PM and will appear 14% brighter and 30% larger. A supermoon happens once or twice a year when the full moon is closer to Earth than during other full moons.
On average, the distance from the Earth to the moon is about 238,000 miles. When the moon is further away from the Earth it's called apogee and when it's closest it's called perigee. The next supermoon is on Sunday, September 27, 2015.
I think there will be enough breaks in the clouds on Sunday night to at least see the moon through them or fully in some spots. If you get a good picture of it then please share with us at email@example.com.
The moon, not full but still very large is going to rise each evening over the next few nights which is when the Perseid Meteor Shower peaks (August 11-13th). You'll have a difficult time seeing the meteors, which could be up to 100 per hour due to the brightness of the moon.
If you wish to attempt to see the meteors then be sure to look up during the pre-dawn hours either on Monday, Tuesday or Wednesday morning and be away from city lights. You may get lucky enough during that time frame because the moon will be in the process of setting so it won't be as high in the sky.
