Indianapolis, IN – A sharp and early-season plunge in temperatures is expected across Indiana heading into Thanksgiving week, raising concerns about frostbite, hypothermia, and dangerous wind chills. Updated projections from the National Oceanic and Atmospheric Administration (NOAA) indicate a major pattern shift beginning November 25, bringing colder-than-normal air across much of the Midwest and potentially lasting into early December.
The developing situation has prompted weather officials and health experts to caution holiday travelers, outdoor workers, and families attending football games or holiday markets to prepare for conditions that could turn hazardous within minutes.
Weather Pattern Driving the Temperature Drop
NOAA’s Nov. 19 outlook highlights several overlapping atmospheric forces contributing to the expected cold surge. According to the agency, the ongoing La Niña, a strengthening Madden–Julian Oscillation, and even the possibility of a rare late-November sudden stratospheric warming event may work together to pull Arctic air deeper into the North-Central and Eastern United States. This combination places Indiana directly in the path of below-normal temperatures that could feel much colder once winds pick up.
Meteorologists explained through NOAA’s latest climate discussion that these overlapping patterns often lead to prolonged cold outbreaks, and residents should anticipate the potential for multiple days of subfreezing air.
Frostbite Symptoms Every Hoosier Should Know
As the holiday approaches, health experts are reminding residents that frostbite can occur faster than many expect, especially when wind chills fall below freezing for extended periods. Frostbite is most likely to strike the fingers, toes, nose, cheeks, and ears.
Key symptoms include:
• Numbness or reduced sensation
• Tingling or prickling feelings
• Skin turning cold, hard, or waxy
• Visible colour changes such as white, red, blue, grey, or purple
• Blisters that appear after rewarming
Medical professionals emphasise that early frostbite may feel deceptively mild, making it easy to overlook until deeper damage has occurred.
Signs of Hypothermia That Require Immediate Attention
Hypothermia is another threat during sharp temperature drops. It occurs when the body loses heat faster than it can produce it. NOAA and health departments warn that seniors, infants, and people spending extended time outdoors face the highest risk.
Common indicators include:
• Shivering
• Slurred or slowed speech
• Shallow breathing
• Weak pulse
• Confusion or memory loss
• Severe fatigue
• Stumbling or clumsiness
• Drowsiness
• In severe cases, unconsciousness
Infants may present differently, often showing bright red, cold skin and unusually low energy.
Safety Guidance for Thanksgiving Week
NOAA advises Indiana residents to prepare for a colder holiday season by dressing in warm layers, covering extremities, and limiting time outdoors during the coldest periods. Windproof outer layers and insulated gloves, hats, and scarves can significantly reduce heat loss. Anyone who begins to experience symptoms of frostbite or hypothermia should move indoors immediately and warm affected areas gradually using warm — not hot — water or gentle body heat.
With many residents planning to travel, watch local football games, or attend community events, officials also emphasise the importance of checking on vulnerable neighbours, ensuring pets are brought indoors, and keeping emergency kits in vehicles.
Extra Caution for Travellers Across the Midwest
Indiana’s expected temperature drop aligns with a broader cold wave projected to affect several Midwestern states. Meteorologists note that pre-Thanksgiving travel is already one of the busiest periods of the year, and cold snaps can increase the likelihood of stranded motorists, icy roads, and vehicle malfunctions. Checking tyres, keeping fuel tanks above half, and packing blankets and water are recommended steps for safer travel.
Preparing for the Weeks Ahead
While forecasts can shift as the holiday approaches, NOAA’s early guidance suggests this could be the first significant cold spell of the season. Residents are encouraged to monitor updated forecasts and stay aware of changing wind chill advisories as the week progresses.
Conclusion
Indiana is bracing for a colder-than-usual Thanksgiving week, and residents are urged to take frostbite and hypothermia risks seriously. Staying warm, staying alert, and preparing vehicles and homes now can make a major difference as Arctic air settles across the region.
