St. Louis wakes up to lingering drizzle this morning, but skies clear out through the day for a partly sunny Sunday with a high near 82°F — about 10 degrees warmer than yesterday, though the National Weather Service notes we’re still nearly 10 degrees below normal for early August. Once that morning drizzle wraps up, it’s a solid day to get outside around Forest Park, the riverfront, or your own backyard grill.

Today’s Setup

A slow-moving low pressure system near Indianapolis is weakening and pulling away, letting clouds decrease from west to east today. That means the western suburbs see sun first and warm the fastest, while areas closer to the Mississippi River hang onto clouds a bit longer and stay cooler. North wind runs around 13 mph with gusts as high as 22 mph, easing down tonight as high pressure settles in — setting up what’s likely the coolest night of this stretch, with lows near 66.

Best Window To Be Outside

Afternoon into evening is your sweet spot, once the morning drizzle clears and clouds thin out. It’s a good window for bank fishing along area lakes and the Mississippi River, or a Sunday round of golf — the light wind and comfortable low-80s temps make for easy walking conditions. If you’re headed out on the water, a pair of West Marine ski vests is worth checking for the family boat, and golfers might want to look at Pinemeadow Golf wedges before tee time.

Rain, Wind, Or Storm Risk

Rain chances stay low today (near 13%) and drop to essentially nothing Monday, when NWS calls for sunny skies and a high in the low-to-mid 80s. The bigger story: after a dry start to the week, shower and thunderstorm chances build back in for the middle-to-later part of the week as the pattern turns more humid.

What To Wear Or Bring

Breezy, cooler-than-average air makes a light layer smart for morning errands. Anglers and anyone spending hours in the sun should grab a UPF 50+ sun hoodie — there’s a $5 deal on one right now worth grabbing before the humidity returns.

Tonight’s Events & Upcoming Games

Busch Stadium hosts the Noah Kahan concert tonight, and with clear skies and a mild mid-60s evening, conditions look great for an outdoor show — grab tickets on SeatGeek or find tickets on StubHub, plus a Noah Kahan t-shirt or Noah Kahan hoodie if you’re heading down. Delmar Hall also has ALL’s Summer Tour stop tonight. Looking ahead, the Cardinals host the Rockies on August 9 at Busch Stadium for Kids Build-A-Bear Fredbird night — stock up on official team gear on Fanatics before first pitch.

Dinner Tonight

With calm evening wind and dry skies, tonight is perfect grilling weather — burgers, steaks, or grilled chicken with corn on the cob all work well. An instant-read meat thermometer and a grill brush and scraper set make cleanup and doneness a lot easier. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.

Next Few Days

Monday brings more sunshine with a high in the low-to-mid 80s, though patchy morning fog is possible after tonight’s calm, clear conditions. Warming continues through the week, and confidence is growing for shower and thunderstorm chances returning by midweek — check back for updates as that system takes shape.
