Every 10 years, our weather team updates the climate stats of the Utica/Rome region. Climate stats include things like the average high and low temperature of a particular day to the average snowfall in the winter season. These new values supercede the previous values. Much can be learned from each update. Let's take a look at the most recent changes.
The 10 year period of 2011-2020 was warmer than the previous decades. The overall warming trend was 0.2°F, but that doesn't tell the story. February, March, and April were cooler than the previous decades, from -0.3 in February to -0.6 in April. From May through the remainder of the year, all other months with the exception of November (-0.2) were warmer than the previous decades.
Temperature trends of 2010s
What can we learn from this trend? It seems to fit the narrative that seasons are, indeed, delayed here in Central New York. It takes longer for spring to arrive, with a clear cooling trend in March and April. It also takes longer for fall to arrive in September and October, with a strong warming signal both months. It also takes longer for winter to settle in, with a strong warming signal in December.
How does this trend fit with the larger picture? The decade of the 2010s saw two record warm years - 2012 and 2020, the 2nd and 5th warmest years on record. Local records go back to the 1880s. Here's the list of top 10 warmest.
Snowfall trends of the 2010s
Snowfall seasons in the 2010s tended to be either a boom or a bust. There were several robust snowfall seasons in the 2010s as well as seasons that significantly underperformed. Large snowfall events helped bring many season averages over 100". The overall snowfall average in the 2010s was 92". Despite being below the previous 1981-2010 average of 95.6”, the new season total will increase to 98.8". This is because the 1980s were significantly less snowy compared to 2010s (74") and this decade is now being removed from the average. Here’s how the trends break down month by month.
Snowfall averages continue to decrease on the fringes of the season (October, April). This is due to warmer overalltemperatures. The largest increase insnowfall takes place in February and March. This is most likely related to an increasing trend in snowier winter storms.
