As Saint Louis residents may have noticed upon stepping outdoors this brisk morning, the clouds overhead promised a continuation of winter's chill, bearing down on the city with a near-freezing hug. The National Weather Service in St. Louis reports current conditions as mostly cloudy, with the temperature standing at 37°F and a wind chill making it feel more like 29°F. The humidity is low at 46%, while the wind speeds hover around the southwest at 12 mph.

For those looking to plan ahead, the NWS forecasts a shift in the weather pattern throughout the day. We're expected to see a gradual clearing of today's overcast skies, leading to a high near 46. However, those winds aren't going anywhere fast, with gusts that might surge as high as 25 mph. Come tonight, the skies should remain mostly clear, but temperatures are set to dip to around 24 with a chilly breeze shifting from southwest to northwest after midnight.

Peering further into the week's forecast, tomorrow offers a partly sunny respite, sporting a more moderate high near 39. Winds are anticipated to remain calm. By tomorrow night, however, prepare to bundle up; temperatures are forecasted to plummet to a low of about 9 degrees, accompanied by northeast winds turning north that could reach up to 14 mph, according to NWS's latest update. This stark drop signals a colder stretch ahead, with mostly cloudy skies and a strikingly frosty high of 15 degrees on Friday.

The below-freezing trend is set to continue into the weekend, with Friday night teasing the possibility of snow after midnight. Forecasters are calling for a 20 percent chance of these flurries turning into a more significant snowfall by Saturday, which holds a 50 percent likelihood. Anyone daring enough to venture out on Saturday will face cloudy and cold conditions with a high near 13, so it might be a good time to find ways to enjoy the indoors.

Snow chances linger into Saturday night and early Sunday, with Sunday afternoon finally breaking into partly sunny weather, albeit cold with a high around 20. Looking ahead to the start of the next work week, Saint Louisans can expect gradual warming. NWS predicts a sunny Monday with a high nearing 23 degrees, leading up to a somewhat more comfortable Tuesday with a high near 36.
