On Sunday, Environment Canada forecast partly cloudy skies for Monday night with a 30 per cent chance of showers early in the evening with the risk of a thunderstorm. Boer said some folks near the Maple Fire in the Olympic National Forest or in the Cascades might still be dealing with smoke and haze and that could reduce visibility. However the peak was occurring between Sunday and Monday.
Of course, the one other thing you need to view the meteors is clear skies, and, as usual in the Northwest, it will be a challenge. "It is really cool when you think about this as you see the these meteors falling from the sky", remarks Dr Quanzhi Ye, a planetary scientist based at California Institute of Technology, USA.
The shower peaks on tonight, 12 August, but will be visible for a day or two either side.
The Perseid meteor shower peaks this weekend and viewing conditions should be spectacular in mid-Missouri.
As the night nears dawn, Cooke says viewers can expect to see a meteor every minute or so, which is about standard for the Perseids.More news: As Turkey's Economy and Lira Dive, Erdogan 'Pleads' for Relief
The meteors are called Perseids because they seem to dart out of the constellation Perseus.
Most of the meteors are no bigger a grain of sand - but as they burn up they produce a bright stream of light which is visible to the naked eye.

This is typically one of the best meteor showers viewable from Missouri. Scientists from NASA also said that camping out in the country can triple the amount of visible meteors.
Here are some facts about the Perseid meteor shower.
