St. Louis, MO – The National Weather Service (NWS) in St. Louis has issued a warning for heavy rain and potential flash flooding across parts of Missouri tonight into early Wednesday morning. Residents are urged to stay alert as the location of the heaviest rainfall remains uncertain. However, there is potential for more than 4 inches of rain where the most intense downpours occur.
According to the NWS, the risk of excessive rainfall leading to flash flooding is significant in the highlighted areas, including parts of St. Louis and surrounding regions. The rainfall is expected to begin late Tuesday and continue into early Wednesday morning, with the heaviest rain likely to fall overnight. This could result in rapid water accumulation, particularly in low-lying and poorly drained areas.

Rain chances increase significantly overnight, with a 50% chance of showers and thunderstorms continuing into Wednesday. Temperatures on Wednesday will peak at 81°F, with a lingering threat of rain.
As the week progresses, the weather will warm up, with temperatures reaching the low 90s by Thursday. The region will see clearer skies and reduced rain chances from Friday through the weekend, offering a brief respite before rain potentially returns early next week.
Residents are advised to monitor local weather reports and be prepared for potential flooding, especially in areas prone to rapid water accumulation. The NWS emphasizes the importance of staying informed and taking necessary precautions as conditions develop.
