St. Louis Braces for Coldest Air Yet This Winter

Saint Louis residents are preparing for what’s expected to be the coldest air mass of the season, arriving significantly by Thursday. Forecasts indicate a dangerous drop in temperatures, with actual air temperatures plummeting into the single digits and wind chills making it feel well below zero. This arctic intrusion will demand diligent preparation and caution from everyone across the metro area.

The Arctic Blast Arrives

A formidable cold front is set to sweep through the St. Louis metropolitan area, ushering in an Arctic air mass that will grip the region with unprecedented cold for this winter season. This profound drop in temperature marks a significant shift, demanding immediate attention to safety and preparedness from all residents. The deep freeze will not only bring frigid air but also sustained, biting winds, amplifying the perceived cold to life-threatening levels and dramatically increasing the risk of cold-related injuries.

Key Forecast Details for Thursday

• Actual Air Temperatures: Expect single-digit lows, potentially dipping near 0°F in some areas by early Thursday morning. Daytime highs will struggle to reach the teens, ensuring a persistently cold environment.
• Dangerous Wind Chills: The most significant concern will be the wind chill values, which are projected to fall between -10°F and -20°F. These extreme values can cause frostbite in as little as 30 minutes to exposed skin.
• Bitter Winds: Sustained winds will contribute significantly to the wind chill, making it feel much colder than the actual air temperature. Gusts will exacerbate these conditions.
• Duration: While the coldest snap is concentrated on Thursday, very cold conditions are expected to linger into Friday morning, albeit with a slight moderation as the weekend approaches.

Impact and Safety Precautions

The severity of this incoming cold snap cannot be overstated, as extreme conditions pose serious health risks for people and pets alike. Beyond the immediate dangers of hypothermia and frostbite, the intense cold also puts significant strain on residential infrastructure, leading to potential issues like burst pipes. Moreover, it’s a critical time to extend care and check on vulnerable populations who may be more susceptible to the impacts of such weather.

Protecting Yourself and Your Loved Ones

• Limit Outdoor Exposure: Reduce time spent outdoors as much as possible. If you must go outside, minimize exposed skin.
• Dress in Layers: Wear multiple layers of loose-fitting, lightweight, warm clothing. A warm hat, scarf or balaclava, gloves or mittens, and waterproof boots are essential.
• Check on Vulnerable Individuals: Reach out to elderly neighbors, those with disabilities, or anyone who might be vulnerable to the cold. Ensure they have adequate heat and supplies.
• Safe Heating Practices: If using supplemental heating like space heaters, keep them at least three feet away from flammable materials and never leave them unattended. Verify that carbon monoxide detectors are functioning correctly.

Safeguarding Your Home

• Prevent Frozen Pipes: Open cabinet doors under sinks and in areas where pipes are located on exterior walls to allow warmer indoor air to circulate. Consider letting a small trickle of cold water run from faucets, especially overnight, to prevent freezing.
• Disconnect Hoses: Remove and drain outdoor garden hoses. Insulate or cover outdoor spigots to protect them from freezing and bursting.
• Seal Drafts: Inspect windows and doors for drafts. Apply weatherstripping or caulk where needed to prevent heat loss and keep your home warmer.
• Maintain Heating Systems: Ensure your furnace or heating system is in good working order. Change air filters as recommended to maintain efficiency.

Care for Your Pets

Pets are highly susceptible to the effects of extreme cold. Bring all indoor pets inside to protect them from the elements. If outdoor pets cannot come inside, ensure they have well-insulated, dry shelters, protected from wind and snow, along with plenty of fresh, unfrozen water and extra food to help them maintain body heat. Limit their time outdoors to only what is necessary for their well-being.
