The National Weather Service in St. Louis forecasts a typical summer week, with temperatures nearing 100°F. There’s also a slight chance of thunderstorms — a reminder of how quickly Midwest weather can change.
Today, be on the lookout after 2pm for a 20 percent chance of rain and thunderstorms, the NWS advises. Things should remain mostly sunny otherwise, with highs pushing a punishing 94°F, and heat index values cranking as high as 100. Tonight, that 20 percent chance of showers and thunderstorms lurks before 8pm, with partly cloudy skies holding lows at around 75°F.
The weekend is expected to bring intense heat, with little to no precipitation likely until Sunday night. Highs from Friday through Sunday are forecast to hover around 95 to 96 degrees, with the National Weather Service describing conditions as sunny with a high near 96. Don’t count on much wind for relief either, as southerly breezes of around 5 to 11 mph will offer only minimal respite from the heat.
Looking ahead to next week, there's a continuation of chances for showers, though it's all rather slight. Monday through Wednesday all carry a 20-30 percent chance of storms according to the latest outlook from the NWS. Temperatures will start to simmer just a tad lower, with Tuesday's high predicted at near 92.
For those planning outdoor activities or just looking to survive the urban sauna without melting into the pavement, it might be a good idea to keep an umbrella handy. However, the NWS Hazardous Weather Outlook doesn't call for spotter activation, so at least there's no need to brace for severe weather.
