2017 Supermoon: Will Weather Allow Viewing In Mercer Island?

MERCER ISLAND, WA - The only supermoon of 2017 will happen Sunday night, but us Pacific Northwest residents might never know it. A supermoon is the closest the moon gets to Earth, making our planet's satellite appear huge in the sky and nearly 17 percent brighter.

We can always hope for a weather miracle, but our viewing chances aren't looking so great, or at least not totally clear. Here's the weekend forecast from the National Weather Service:

Friday night: Rain. Low around 41. South wind 5 to 13 mph. Chance of precipitation is 80%. New precipitation amounts between a tenth and quarter of an inch possible.

Saturday: Showers, mainly after 10am. High near 45. South southeast wind 5 to 7 mph. Chance of precipitation is 80%. New precipitation amounts between a tenth and quarter of an inch possible.

Saturday Night: Showers likely, mainly before 10pm. Cloudy, with a low around 38. South wind around 7 mph becoming west in the evening. Chance of precipitation is 70%. New precipitation amounts between a tenth and quarter of an inch possible.

Sunday: A 20 percent chance of showers before 10am. Mostly cloudy, with a high near 43. Northwest wind around 7 mph.

Sunday Night: Mostly cloudy, with a low around 35.

The supermoon phenomenon which occurs when the moon reaches a point closer than usual, shone brightly Tuesday night in Beijing, as the smog that often blankets China's capital city and most of the industrial north in winter subsided for the evening.
