Reading KSTL's weather

KSTL — St. Louis Lambert International — sits at 618 ft MSL in St. Louis, MO. It is a towered field and issues its own TAF, so you get both an observation and a forecast on this page.

Start with the flight category, then verify it yourself: the ceiling is the lowest broken (BKN) or overcast (OVC) layer — scattered clouds never count. On hot days, a wide temperature/dewpoint spread means high density altitude rather than fog risk; a narrow spread is the classic fog setup. Learn how to read every group →
