Chilly Skies and Light Flurries: A Frigid Start to February in St. Louis

Winter’s Grip Tightens Across the Gateway City

St. Louis residents are waking up to a stark reminder that winter is far from over. As we move into Sunday, February 1, 2026, the region is experiencing a significant cold snap that is expected to persist throughout the day. After a relatively mild end to January, an Arctic air mass has settled over the Mississippi Valley, bringing sub-freezing temperatures and the potential for the first snowfall of the month.

Morning Forecast: Frosty Beginnings

Early risers can expect a biting start to their Sunday. Temperatures in the early morning hours have dipped into the single digits, with a recorded low of approximately 7°F. Combined with a light breeze from the northwest at about 8 mph, the wind chill is making it feel closer to -2°F. Visibility may be an issue for those on the roads early, as some forecast models indicate the presence of freezing fog across the metro area. This can create slick spots on overpasses and bridges, so commuters and churchgoers are advised to exercise caution.

Afternoon Outlook: Cloud Cover and Snow Chances

As we move into the afternoon, the mercury is expected to climb slowly, reaching a projected high of 28°F. While the sun may attempt to peek through early on, cloud cover will thicken significantly by midday. St. Louis remains under an unsettled weather pattern, with a 20% chance of light snow showers or flurries throughout the afternoon hours. While major accumulations are not anticipated today, the light dusting could contribute to a festive but freezing atmosphere across the city. The humidity is expected to hover around 70%, adding a damp chill to the air.

Evening and Overnight: The Deep Freeze Returns

The mercury will begin another steady descent once the sun sets around 5:22 PM. Evening temperatures will quickly drop back into the teens, eventually bottoming out near 6°F overnight. The sky will remain mostly cloudy, which may trap some residual heat, but it will not be enough to ward off the frigid conditions. There are no active wind or rain warnings at this time, but the extreme cold poses a risk for those spending extended periods outdoors.

Stay Safe and Warm

Given the single-digit lows and the potential for freezing fog, the editorial team at stlouis.news recommends the following precautions for today:

• Wear multiple layers, including a moisture-wicking base layer and a wind-resistant outer shell.
• Check on elderly neighbors and ensure pets are kept indoors during the overnight freeze.
• Be mindful of black ice if traveling on secondary roads where freezing fog may have settled.

Looking ahead, the cold is expected to linger into the work week, though temperatures may see a slight recovery by Tuesday. For now, keep the heavy coats and ice scrapers handy as St. Louis braves this frosty February opening.
