As St. Louis residents wake up to a chilly morning with temperatures plunging into the teens, the National Weather Service urges the public to brace for cold snaps and potential hazardous weather conditions. According to the latest NWS forecast, a mostly cloudy sky is soon to give way to sun, with the high inching towards 30 degrees. But it's not the calm before the storm—quite literally—as wind speeds are expected to remain calm, later becoming a subdued west wind between 5 and 9 mph as we progress through the morning.
The NWS alert details a "Cold Weather Advisory" in south central Illinois, where the wind chill readings could harshly drop to 10 to 15 degrees below zero. "Dangerous wind chill readings between 10 to 15 degrees below zero are expected this morning across parts of south central Illinois," the Hazardous Weather Outlook by the NWS cautions, emphasizing the urgency of such a warning in effect until 9 AM. Tonight's forecast further predicts an overcast sky with the low temperature hovering around 10 degrees, while a timid northeast breeze is set to slowly become noticeable post-midnight.
Looking ahead, Thursday seems bleak with an overcast palette presenting a high near 24 degrees. A gentle northeast wind will persist, maintaining its presence at a mild 3 to 6 mph. As the weekend approaches, frigid conditions seem to stubbornly linger, with Friday's high struggling to reach 18 degrees amidst uniformly north winds pressing at 5 to 9 mph. That particular evening forecasts an even lower plunge, betting on a low circling near 1 degree.
Saturday’s outlook remains steadfast in the cold, promising mostly sunny skies yet capped with a high still stuck at 18 degrees. As night descends, the region can expect mostly clear conditions, with the thermometer dropping to approximately 3 degrees. It is not until Sunday afternoon that residents might see a slight shift, as there is a slight chance of snowflakes gracing the city, with a 20 percent likelihood after noon. Despite this, the high is predicted to climb—slightly more generous—near 27 degrees. "No hazardous weather is expected at this time," writes the Hazardous Weather Outlook regarding the days following Sunday, indicating a fleeting respite from the biting cold as temperatures possibly reach the mid-30s at the start of the new week.
The current weather patterns suggest residents should continue to remain cautious and appropriately layered in the face of persisting winter temperatures and potential brief snowfalls. The NWS advises to keep tuned to weather updates as St. Louis grapples with this cold stretch.
