Will it be clear enough to image tonight? Radar, hourly forecast, and a full astrophotography conditions assessment for your location.

Current temperature, wind, cloud cover, and other conditions at your location. Hover any label for an explanation of how it affects astrophotography.
Official National Weather Service alerts for your area. Watches mean hazardous weather is possible in the next 24–48 hours. Warnings mean it's happening now or imminent.
Scroll right to see the next 24 hours. Look for the clear-sky windows — these are your best imaging opportunities. A run of clear hours after midnight is often the sweet spot.
Plan upcoming imaging sessions. Look for nights with low cloud cover (bottom chart), low dew spread (temperature close to dew point = dew risk), and low precipitation. New Moon nights with clear forecasts are golden.
Each row is one day, broken into hourly colour-coded segments. Blue/teal = clear, dark grey = overcast, lighter shades = partial cloud. The darker the night hours, the better the imaging conditions.
These scores are calculated specifically for astrophotographers. A high Imaging Score with good Seeing and Transparency means tonight could produce excellent results.
