Philadelphia is currently experiencing high humidity levels, which are significantly impacting the visibility of the night sky. The city is enveloped in moisture-laden air, leading to reduced clarity for stargazers and astronomers. High humidity creates a hazy atmosphere, obscuring stars and planets. This occurs during periods of elevated moisture, scattering light and reducing contrast needed for astronomical observations. The weather pattern is expected to persist, affecting visibility for those hoping to enjoy clear night skies. Meteorologists advise checking detailed weather forecasts before stargazing.
