ST. LOUIS, MO–IL – A crisp dawn breaks over the Mississippi River, mist rising off the water as Missouri eases into Halloween morning under clear, star-strewn skies. The air feels still and cool — a true fall morning, where lawns glisten faintly with dew and porch lights cut through the chill.
The National Weather Service in St. Louis reports a quiet, comfortable stretch ahead. After a chilly start in the low 40s, sunshine takes control by midday with highs near 60°F. Light westerly breezes linger through the afternoon, creating ideal conditions for outdoor errands, early trick-or-treat setups, or evening events.
Saturday brings partly sunny skies and highs in the mid-50s, with clouds brushing through the metro but little chance of rain. Sunday turns slightly warmer as calm southerly winds return, pushing afternoon readings into the upper 50s to near 60°F. Nights will still dip into the upper 30s and low 40s, cool enough for a jacket but far from winter’s bite.
The extended outlook shows no major weather threats, but longer-range models hint at a pattern shift by mid-November, possibly introducing a colder push from the Plains. For now, the St. Louis region enjoys a picture-perfect early November — blue skies, mild sunshine, and crisp, breathable air, the kind that reminds residents to rake leaves, savor the weekend, and soak up fall before winter begins to whisper.
