St. Louis, Missouri – Relief from early-week storms arrives Friday, August 1st, as the St. Louis metro area enters a stretch of dry, sunny weather along the Missouri-Illinois border.

According to the National Weather Service in St. Louis, skies will clear throughout the day Friday with a high near 82°F and a light northeast breeze between 6 to 10 mph. Friday night will be mostly clear and cooler with a low around 61°F, offering a refreshing change from recent muggy nights across the Metro East and downtown corridor.

This calm, pleasant pattern will continue through Sunday. Areas from Soulard to Brooklyn, IL, including key routes like I-64 and I-55, can expect minimal travel disruptions and ideal conditions for outdoor plans. No hazardous weather is expected through the weekend, making it a perfect window for festivals, park outings, and errands.

Thunderstorm chances return briefly Monday afternoon and continue into Tuesday evening, with increased cloud cover and highs in the mid-to-upper 80s. Spotter activation is not expected at this time.

Residents should take advantage of the dry spell to prepare for the next round of summer storms, especially if power backups or roof maintenance are needed after this week’s rainfall.
