The annual performance of the Perseid meteor shower is due to reach its peak late on Sunday night (Aug. 12) into the predawn hours of Monday morning. This is the most famous of all meteor showers, and the Perseids never fail to provide an impressive display.
In the Astronomical League guidebook "Observe Meteors," astronomers David Levy and Stephen Edberg wrote, "We have seen Perseids coming in such rapid succession that counting and recording were difficult, followed by slack periods with little activity." This year is an excellent one for the Perseids, because they will reach their maximum on a new moon weekend; without any bright moonlight, skywatchers will be able to see many fainter streaks.
But in order to enjoy the sight of "shooting stars," clear skies are necessary. And unfortunately for parts of the United States, widespread cloud cover as well as airborne smoke from wildfire activity out west will hinder the view. If bad weather does spoil your view, you can also watch the Perseid meteor shower live here on Sunday (Aug. 12) starting at 5 p.m. EDT (2100 GMT), courtesy of the online observatory Slooh.com. The Slooh.com webcast, which you can also follow here at the Slooh website, will offer live commentary and views of the annual meteor shower. [Perseid Meteor Shower 2018: When, Where & How to See It]
Latest weather outlook
The best viewing conditions this weekend will likely be over the northern and central Great Plains as well as parts of the Midwest, where skies are expected to be generally clear. In contrast, clouds, showers and scattered thunderstorms will thwart prospective meteor watchers in a swath extending from the southern Great Plains northeast through the Carolinas, the Middle Atlantic states and on up into the so-called "Northeast Corridor," running from Washington and Baltimore to Philadelphia, New York and Boston.
And in some places, a sky free from clouds will not automatically mean a good view for the meteors. Smoke from the California wildfires that now covers parts of the western U.S. may create hazy sky conditions capable of significantly dimming bright stars — and bright meteors. This is especially true for areas that are located immediately downwind of the wildfire zone. In many western locations, the word "smoke" has been appearing in recent forecasts issued by the National Weather Service.

Are meteors related to meteorology?
By profession, I'm a television meteorologist, and many people think that all meteorologists know a lot about meteors. That's not true, though, despite the similar names. The word "meteor" comes from the ancient Greeks and means "in the air." Until the 18th century, this term was also used to describe other natural phenomena, such as auroras, lightning, rain, hail, snow and clouds, which are now studied in meteorology.
Meteors on the other hand originate in space, where there is virtually no air. They begin as particles that have been shed from a comet's nucleus. When these particles ram through our atmosphere at very high speeds, atmospheric friction causes them to blaze up within the space of a heartbeat. And they leave behind a very hot trail of gas, which creates the effect of a "shooting star."
This all happens some 50 or 60 miles (80 or 100 kilometers) above our heads. So, while meteors are indeed "in the air," they are totally different from what your local weather forecaster looks at to put together a daily forecast!
