Duncan, Oklahoma sits on open, gently rolling land in south-central Oklahoma, with no nearby mountain wall to block moving air. Gulf moisture often flows north across the plains, while drier air arrives from the west and colder air drops from the north. Their clashes bring changeable skies.
High pressure often brings calmer, clearer stretches, especially after a cold front passes. When pressure falls as a low moves in from the west or southwest, winds strengthen and clouds build. Springtime clashes can produce thunderstorms, sometimes with heavy rain or hail.
Summers are long, hot, and often humid, with afternoon storms. Spring shifts quickly between warm, stormy days and sharp cool fronts. Winters are milder than farther north, though cold snaps can bring freezing rain or occasional snow. Fall cools gradually, often bringing dry, mild days.
