Saint Louis, MO – Commuters across the Saint Louis metro area can expect a beautiful, summer-like stretch of weather before a significant storm system arrives to end the work week. Tuesday is starting with a mild 58 degrees at Lambert International Airport, and with mostly sunny skies, temperatures are set to climb to a warm high near 81 degrees. While the drive on I-64 and I-44 should be clear today, drivers should be aware of southwesterly gusts hitting 25 mph, which could create a slight challenge for high-profile vehicles on open overpasses.
According to the National Weather Service, the dry conditions will persist through Wednesday and most of Thursday as the region remains under a ridge of high pressure. Thursday afternoon looks particularly warm with a high of 83 degrees, though wind speeds will increase, gusting up to 28 mph. The primary weather concern arrives late Thursday night, as a 70 percent chance of showers and thunderstorms develops after 1 a.m., potentially leading to a wet and slow-moving Friday morning commute.
The moisture is expected to be widespread on Friday, with an 80 percent chance of precipitation and embedded thunderstorms. While severe weather isn’t currently the main headline, the volume of rain could lead to localized ponding and reduced visibility across the metro. The front will also bring a slight cooling trend, with highs dropping back into the mid-70s as the rain tapers off toward Friday night.
Conditions should start to stabilize by Saturday afternoon, though a 20 percent chance of showers lingers. For now, the best strategy is to enjoy the unseasonably warm midweek sun but ensure your umbrella is ready for the messy weather moving in for Friday.
