Residents of St. Louis and surrounding areas are bracing themselves for a wet Wednesday, with the National Weather Service in St. Louis forecasting a 60% chance of showers and possible thunderstorms later in the day. Humidity lingers at a sticky 97%, making the overcast skies feel even more oppressive. It's a dreary morning in the city with temperatures hovering at around 67°F, as reported by the NWS early today.

According to the NWS detailed forecast, we should be ready to quickly bring to use our umbrellas before 1pm, and then again keep an eye out for showers and thunderstorms that might hit between 1pm and 5pm. The chances of precipitation will not start to diminish until after 5pm. If you're hoping for a glimpse of the sun today, you might want to wish on something stronger than a four-leaf clover, as patchy fog will hold the city in its grasp before 10am.

Tonight, the gloom continues with more showers and potentially a thunderstorm before midnight, tapering off with just a slight chance of showers between midnight and 2am. But there might be some respite in sight—forecasts predict cloudy skies will begin to clear, with lows dropping to around 60°F. Thanks to a north wind blowing at 5 to 7 mph, tomorrow promises clearer skies.

Looking ahead at the rest of the week, the NWS anticipates notably sunnier days with highs in the upper 70s to upper 80s. Thursday should rise to near 78°F, while Friday promises a warmer high of around 81°F. The good weather is here to remain consistently through the weekend, offering up a sunny Saturday with highs pushing into the lower 80s, and a clear nighttime sky as the temperature dips near 60°F.

The Hazardous Weather Outlook, also released by the National Weather Service St. Louis MO, has not signaled any severe weather alerts for the coming days, post-storm. From Thursday through Tuesday, no hazardous conditions are anticipated, providing a much-needed break from today's tempestuous weather.
