The National Weather Service in St. Louis has reported, as of 5:51 am CST this morning, a mostly cloudy sky with temperatures sitting at 40°F and a humidity level at 86%. The city is expecting a day of overcast conditions, where the temperature will barely climb to a high near 40 degrees, accompanied by light winds that will shift to the north and could gust as high as 21 mph. Residents might feel a chill as the wind increases, despite a relatively stable 39-degree temperature.

Looking ahead into the evening, the forecast anticipates temperatures will drop to a low around 23 degrees with a persistent north wind blowing between 6 to 11 mph. To wrap up the weekend, Monday should expect mostly cloudy skies which will gradually clear up to become sunny, with a high approaching 34 degrees. Gentle winds from the north are set to become calm, according to the detailed forecast by the NWS St. Louis.

As the week progresses, Tuesday is predicted to bring mostly sunny skies with temperatures making a more comfortable climb to around 53 degrees. However, a southwest wind will persist, potentially gusting to around 21 mph. This trend will shift slightly by midweek with a partly sunny Wednesday, leading to a night that presents a 20% chance of rain and snow after midnight—though precipitation during the day remains unlikely.

The latter part of the week presents a mix of rain and snow chances, particularly on Thursday with a 30% chance before noon, followed by a slight possibility of rain through the afternoon. Daytime highs will likely hover near 38 degrees. As the week closes, St. Louisans can expect temperatures to drop significantly, with Friday's high forecasted to reach a mere 26 degrees and a frigid low around 8 degrees come Friday night. The weekend remains cold, with Saturday's daytime temperatures only expected to top out near 22 degrees, as per the NWS forecast.
