Missouri — A soft glow spills across the Mississippi River this early morning, reflecting off damp sidewalks and drifting through pockets of thin clouds over St. Louis.

The calm scene masks a subtle but important weather shift building for the second half of the weekend. Warm, steady breezes sweep through the metro, hinting at a short-lived stretch of late-fall comfort before Monday’s rain chance disrupts the pattern.

Residents should use the mild conditions today and Saturday to prepare for next week’s early holiday travel—roads dry quickly this morning, but gusty southwest winds may push vehicles on elevated stretches of I-55 and I-64 later in the day. Outdoor chores, early decorating, and yard cleanup all benefit from the warm air ahead of cooler changes on the way.

Skies trend partly to mostly sunny through Saturday, with highs climbing into the upper 70s and even touching 80 in a few southern suburbs. It’s a classic mid-November warm snap—pleasant, but usually a hint of something different lurking upstream. Models now signal an early sign of a Winter Tease, not with snow, but with a cooler, unsettled push that arrives Monday.

Clouds thicken by Sunday night as moisture lifts north. Monday brings a slight to moderate rain chance, most likely after midday. The warm-to-cool shift could tighten quickly, although temperatures stay too high for any ice or snow. Still, a brief drop into the 40s Monday night signals the broader transition toward colder Thanksgiving-week patterns across the Midwest.

Early indications show multiple disturbances next week, including a stronger system that could affect pre-holiday travel regionally. For now, expect a mild weekend, a wet Monday, and a steady cool-down after that.
