The lights are seen above the magnetic poles of the northern and southern hemispheres.
It often takes a few days for powerful flares from the sun, known as Coronal Mass Ejections (CMEs), to hit Earth and stoke a space storm.
If you're lucky enough to view the lights and are able to grab photos, we'd love to see them. You'll need to find an area away from the bright lights of the city-and make sure you're pointed north.
In the past, the lights have actually been seen throughout the United Kingdom - even as far south as Kent and Cornwall.
Canada's Northern Lights Centre says the northern lights are "the result of collisions between gaseous particles in the Earth's atmosphere with charged particles released from the sun's atmosphere".
However, as various weather conditions have to align perfectly for the phenomenon to appear, a sighting is far from guaranteed. If the storm is significantly stronger than forecast, reaching the extreme end on a scale of geomagnetic intensity, it could be visible across Maryland, but that is not expected.
Aurora Borealis, or the Northern Lights, may be visible in the skies over Ireland this weekend.
Variable amounts of cloud will build through the day but should break up after dark so there should be good clearer spells developing.
