Manchester, NH – A sharp blast of unusually cold air may sweep across New Hampshire during the Thanksgiving week, raising the risk of frostbite and hypothermia for residents and travelers, according to newly updated projections from the National Oceanic and Atmospheric Administration (NOAA). The agency’s 8–14 day climate outlook released on Nov. 19 indicates a major pattern shift beginning November 25 that will usher colder-than-normal conditions into the Northeast through early December.
Colder Air on the Way for the Northeast
NOAA’s latest analysis suggests that several atmospheric drivers are working together to create this early-season cold spell. Meteorologists point to the ongoing La Niña pattern, the influence of the Madden–Julian Oscillation, and the potential for a rare November sudden stratospheric warming event. These combined forces may allow Arctic air to spill into the North-Central and Eastern United States, placing New Hampshire directly in the below-normal temperature zone. The agency noted in its update that this shift could bring weather conditions more typical of mid-winter than late November.
Why the Timing Raises Safety Concerns
With Thanksgiving approaching, many residents and visitors traditionally spend more time outside attending parades, community tree lightings, football games, and early-morning shopping lines. This year, the dramatic temperature drop increases the likelihood of cold-weather injuries. Even brief exposure to frigid air can lead to frostbite or hypothermia if people aren’t properly prepared.
Health officials across New England consistently warn that frostbite can set in when wind chills fall near or below freezing, especially on exposed skin. Hypothermia risk increases even faster when people are outdoors for long periods, wear inadequate clothing, or get wet from snow or cold rain. As holiday travel begins, these risks become more significant for anyone stranded, delayed, or spending extended time outdoors.
Recognizing Early Frostbite Symptoms
Understanding the body’s warning signs is essential. Frostbite symptoms often begin subtly before becoming severe. Common signs include:
• Numbness or loss of feeling
• Tingling or prickling sensations
• Cold, hard, or waxy-looking skin
• Noticeable changes in skin tone, including red, white, blue, gray, or purple
• Blisters that may appear hours after rewarming
Medical experts stress that frostbite is most likely to affect the ears, nose, fingers, toes, and cheeks. Ignoring the early symptoms can lead to long-term tissue damage.
Ten Key Indicators of Hypothermia
Hypothermia poses an even greater threat because it affects the body’s core temperature. NOAA emphasizes awareness of the top signs:
Shivering, slurred speech, shallow breathing, weak pulse, fatigue, confusion, memory loss, drowsiness, stumbling, and—at its most dangerous point—loss of consciousness. Infants may present with bright red, cold skin and low energy, which can be mistaken for normal tiredness during holiday activities.
How Residents Can Stay Safe This Week
NOAA advises the public to take extra precautions as the cold pattern develops. Dressing in multiple warm layers, covering exposed skin, and wearing insulated gloves and hats can reduce frostbite risk. Warm, waterproof footwear is also important during outdoor events or travel.
The agency also recommends limiting time outside during early morning or evening hours when temperatures dip the most. Those who must be outdoors should take frequent breaks indoors to rewarm. If frostbite or hypothermia symptoms appear, immediate medical care is essential; affected areas should be warmed with comfortable, warm water rather than hot water to prevent further damage.
Why This Cold Pattern Matters for Holiday Travel
Thanksgiving is one of the busiest travel periods of the year, and cold air outbreaks can create added complications. Delays, vehicle breakdowns, or slippery conditions may leave drivers exposed to dangerous wind chills. Emergency officials encourage travelers to pack blankets, gloves, snacks, and a charged phone in case of roadside emergencies. Bringing spare winter gear for children and older adults is especially important, as both groups face higher risks from extreme cold.
Conclusion
The upcoming temperature drop could create dangerous conditions across New Hampshire as Thanksgiving approaches. With NOAA highlighting a significant shift toward colder-than-normal weather, residents and travelers are urged to stay prepared, dress appropriately, and recognize early signs of frostbite and hypothermia. Staying alert and cautious this week will help ensure a safer holiday season for everyone.
