In an impressive display of nature's raw power and beauty, 15 to 20 meteors per hour will slam into the atmosphere at nearly 110,000 miles per hour.
The ancient phenomenon - which has been happening for the last 2,600 years - is caused by Earth's annual crossing of the path of Comet Thatcher, more formally known as C/1861 G1.
At the shower's most intense, up to 200 meteors per hour will enter our atmosphere.
The best thing to do in the meteor shower is to go out there, lie on your back and look straight up
Nasa spokesman Tony Phillips said: "A typical Lyrid shower produces 10 to 20 meteors per hour over the northern hemisphere.
"But occasionally, Earth will pass through a dense region of the comet's tail and the rates will increase five to ten-fold.
"Flakes of comet dust will strike Earth's atmosphere and disintegrate as fast streaks of light."
The brightest meteors will leave a train of fading light that will be visible for several seconds.
The best place to see the meteor shower will be deep in the countryside, where light pollution is at its lowest, between 1 and 2am on Tuesday morning.
No special equipment is needed, but experts recommend lying down and looking directly upwards to maximise your field of vision.
"The last thing you want to do is look at Lyra, which is the direction of the radiant, because the meteors in that direction have very short tails and will appear as a dot to you.
"The best thing to do with any meteor shower is to go out there, lie on your back and look straight up."
As for Comet Thatcher, she was last seen in 1861 and won't be visiting the Earth's section of the Solar System again for another 300 years.
Major Lyrid outbursts - spectacular displays of light caused by huge numbers of meteors entering the atmosphere - have been recorded in 1803, 1922, and 1982.
Many minor Lyrid outbursts have also occurred in recent years.
