No white Christmas for Nome and the region

Nome experienced an unusual snowless Christmas despite not having a dry December, with rain replacing snow and creating icy conditions that hinder traditional winter activities and local events.

Comment from Gemini:

The attached articles document unusual weather events in Nome, Alaska, over several years, offering context for the current snowless conditions. Several articles highlight the impacts of fluctuating weather patterns, including unusual warmth, high winds, and heavy precipitation in various forms.

• 2024: Deep snow and high winds caused disruptions, contrasting sharply with the current lack of snow. This highlights the year-to-year variability in winter weather.
• 2023: A mix of snow, wind, and rain caused significant disruptions, emphasizing the region's vulnerability to extreme weather events and the potential for unusual precipitation patterns. This observation also cites climate change as a contributing factor to these unusual weather patterns, potentially linking this year's low snow to the larger trend. [Source: KNOM Radio.

• 2022: Unusually warm weather and freeze-thaw cycles created hazardous conditions, similar to the current situation but occurring earlier in the winter season. This suggests a pattern of unseasonable warmth impacting Nome.
• 2021: High winds, heavy snow, and rain, driven by an atmospheric river event ("Pineapple Express"), resulted in the wettest December since 1931. This contrasts with the current dry conditions but demonstrates the region's susceptibility to extreme precipitation events originating from the south.
• 2016: An early spring and lack of stable sea ice caused safety concerns and loss of life and equipment. While this observation focuses on spring conditions, it highlights the potential consequences of unstable ice conditions, which may become relevant in Nome if the current lack of snow leads to unsafe ice formation later in the season.

The current lack of snow in Nome, following a December with near-average precipitation, suggests a shift in temperature profiles contributing to rain rather than snow. This aligns with broader climate change trends in the Arctic, which is warming at a rate several times faster than the global average [Source: Arctic Report Card: Update for 2022 | NOAA Climate.gov. (n.d.). https://www.climate.gov/news-features/featured-images/arctic-report-card-update-2022 ]. The warm temperatures and low sea ice extent described in the article likely contributed to the unusual warmth in December, creating a positive feedback loop that further inhibited snowfall. The long-duration windstorms mentioned, while not unprecedented, further complicate the situation by potentially exacerbating ice instability and hindering snow accumulation.
