St. Louis experienced pockets of dense fog early Monday, mainly south and southeast of the city along with western river valleys, before clearing for a spell of unseasonably mild weather.

Monday’s Transition from Mist to Mild

Dense fog reduced visibility in targeted areas during the morning hours. Conditions improved rapidly as sunlight penetrated, lifting the haze across the region. Afternoon skies turned sunny, allowing temperatures to climb into the mid-60s.

Evening brought partly cloudy skies. Overnight lows dipped into the 40s, setting comfortable out-the-door temperatures for Tuesday morning commutes.[1]

Breezy Tuesday with Increasing Clouds

Winds picked up on Tuesday, delivering another warm day with highs reaching the mid-60s once more. Cloud cover built throughout the day, hinting at shifting patterns aloft. Breezes contributed to a lively feel outdoors.

A slight chance of showers emerged Tuesday evening into the night. Most areas likely stayed dry, though scattered precipitation remained possible. Lows held steady in the 40s overnight.[1]

Wednesday’s Record-Challenging Warmth

Sunny skies dominated Wednesday, paired with persistent breezes. Highs pushed into the 70s, approaching the daily record of 74 degrees. Such warmth marked a notable departure from recent cooler trends.

The comfortable conditions encouraged outdoor activities. Winds kept the air moving, preventing stagnant humidity buildup. Another mild night followed, though specifics on lows were not highlighted.[1]

Thursday’s Shift Toward Storms

Warmth lingered into Thursday, but attention turned to incoming moisture. A chance of rain and thunderstorms developed, potentially disrupting the dry streak. Highs remained above average despite the weather shift.

Forecasters noted the setup for active weather late in the week. Rainfall amounts stayed uncertain, with isolated storms most probable. Cooling arrived promptly afterward.[1]
