As St. Louis residents soak up a partly cloudy morning with temperatures nestling at a comfortable 61°F, the National Weather Service (NWS) provides a glimpse into what the upcoming week has in store, with a forecast that promises an escalation in the midwest mercury and an eventual stormy intervention. The current humidity holds at 72%, with a westward wind breezy enough to rustle through at 7 mph.
Today’s generous share of sunshine is expected to push the thermostat to a high near 84, while a confident northwest wind gusts through, adding movement to an otherwise serene day; this evening's shift towards partly cloudy skies will accompany a low around 62. Looking ahead, Sunday maintains the mostly sunny status with the mercury climbing slightly higher to an anticipated 85 degrees, as detailed by the National Weather Service.
As forecasted by NWS, Monday will continue the trend with sunny skies and a more pronounced high near 88, but by Tuesday, you’ll notice a shift toward a partly sunny tapestry and an uptick to near 90 degrees; Tuesday night teases the possibility of showers and thunderstorms after 1 a.m., standing at a squally 40% chance. Wednesday daytime steps it up, declaring a 70% likelihood for showers and potential thunderstorms in an otherwise mostly cloudy sky.
The week’s weather narrative peaks on Thursday as showers and the possible thunderstorm are slated to become the primary characters, with an 80% probability, while Friday dials back slightly to a 40% chance of rainfall amidst mostly sunny skies—a high near 81 marks a temperate end to the week’s roller coaster conditions. The NWS has also issued a Hazardous Weather Outlook encompassing eastern and central Missouri as well as west central and southwest Illinois, forewarning that "There is a chance of thunderstorms today across Illinois and tonight across central and southeast Missouri."
