Look toward the northern horizon. Cloud cover is 45% right now.
There is a real chance of aurora tonight. If you go outside, find a dark spot away from city lights and look north.
Some cloud cover is present but viewing is still workable.
The strongest window in the next 72 hours looks to be around Fri, May 1 · 00:00 UTC, at about 89% cloud-adjusted visibility.
We combine three inputs to produce a single cloud-adjusted visibility probability:
NOAA SWPC's 3-hour geomagnetic activity forecast — how strong the aurora-driving storms are.
The boundary 66.5° − 2.5 · Kp — the lowest latitude where aurora is normally visible.
Open-Meteo's hourly cloud cover for your location. Heavy clouds reduce visibility proportionally.
