St. Louis will start Sunday with a chilly 28-degree low, but sunshine will quickly take over as temperatures climb toward 55 degrees. A brief patch of morning fog could slow visibility around 8 to 9 a.m., giving the day one last bit of November drama before the skies clear.

Sunny Sunday Sets Up A Gradual Warmup

Winds will stay light from the east at around 2 mph, and no rain is expected Sunday. The National Weather Service in St. Louis is also calling for another mostly clear night, with temperatures dipping to about 32 degrees by Monday morning.

Monday will remain sunny with a high near 57, followed by another cool night near 34. The warming trend becomes more noticeable Tuesday, when St. Louis could reach 59 degrees, then Wednesday, when mostly sunny skies and a high near 63 are expected, according to the National Weather Service.

Upper 60s Arrive Before A Weekend Rain Chance

Temperatures could reach 67 degrees Thursday and 69 degrees Friday under mostly sunny skies, with only a small chance of precipitation during that stretch. Saturday looks warmer still, with a high near 71 and a 30% chance of rain.

The updated outlook pushes the warmup higher than the forecast published Saturday in Hoodline's earlier St. Louis forecast, which had Sunday topping out closer to 52 degrees. For now, the local game plan is simple: coat in the morning, sunglasses by afternoon, and maybe a lighter jacket waiting in the car later this week.
