Significant weather changes are on the horizon for St. Louis as precipitation clears up, making way for fog, clouds, and chilly temperatures. According to reports, varying amounts of precipitation, ranging from a dusting to over 2.5 inches, were recorded. The highest accumulations were observed in St. Louis County and the neighboring metro east region.

Today, the city can expect a continuation of dreary conditions, with the possibility of spotty sprinkles or flurries in the afternoon. However, there are no additional accumulations expected, and temperatures will remain in the 30s.

As nightfall approaches, patchy fog may develop, with temperatures dropping to near freezing. The following day, St. Louis residents can anticipate a dry but cloudy Sunday, with the possibility of sunshine breaking through the clouds in the afternoon. Although temperatures will inch upward into the 40s, the prevailing coolness will persist.

Looking ahead, Monday promises to bring an intriguing weather pattern to the area. The day will begin with dry conditions and temperatures climbing to the mid-40s. However, in the afternoon, rain and a potential rain/snow mix will make its way into St. Louis and surrounding areas.

For commuters on Monday evening, mainly rain is anticipated in the metro area, while a wintry mix is expected to the west. The rain will continue overnight and into Tuesday morning. Current projections indicate no significant accumulations until Tuesday morning, but a transition from rain to a mix and eventually to all snow is predicted for the afternoon and evening hours, moving from west to east.

Snowfall during this event is expected to be significant, with the highest amounts centered on a line from west of Columbia to Quincy. Snowfall totals will decrease further east. St. Louis is likely to be on the southeastern edge of the higher accumulation potential, with a roughly 30% chance of exceeding 5 inches. However, it should be noted that the storm is still a considerable distance away, having just moved onshore over the Pacific Northwest.

The storm's exact track remains uncertain, which means the swath of significant snowfall could shift north or south. Furthermore, gusty winds accompanying the snowfall may cause blowing snow, leading to limited visibility at times. St. Louis residents are advised to stay informed about the developing weather conditions and take necessary precautions as the winter storm approaches.

As always, meteorologists will continue to monitor the storm's progress and provide timely updates to keep the public well-informed.
