Pennsylvania
Can you see the northern lights in Pennsylvania tonight?
Not tonight.
Kp is 2.7. Pittsburgh needs Kp 9+ for the oval overhead — right now it’s not reaching Pittsburgh.
Tonight's peak is forecast around Kp 5.0 (Minor storm). The forecast still depends on darkness, cloud and the moon at your exact spot.

What Kp does Pennsylvania need?
Pittsburgh is the one place we cover in Pennsylvania — it needs Kp 9 or above before the oval climbs into view, which happens only a few times a solar cycle, in the very biggest storms. A high Kp is never the whole story though: you also need darkness, clear sky and little moonlight.
