Extreme temperatures come more often in the winter in Southern Tier
Scientific studies continue to document more extreme climate conditions ranging from droughts, heat waves and flooding around the globe. But what’s happening locally?
If it seems like temperatures in the Southern Tier of New York are more extreme than a few years ago, there’s some supporting evidence in local weather statistics, especially in the winter.
The chart above compares the daily average temperature with the normal average for that date based on readings at the Elmira-Corning Regional Airport. The wider the band for a year, the greater the deviation from normal.
In 2018, the coldest departure from normal was on Jan. 6, when the average temperature for the day was 4 degrees. That was about 20 degrees colder than the norm. The next month saw the warmest departure, with an average of 54 degrees on Feb. 21. That was 24 degrees warmer than normal.
When compared to 2010’s extremes, 2018 had extremes about five degrees hotter and colder.
When the same data is sorted by month, the visualization shows that extreme readings are occurring much more often in the winter than the summer.
A Penn State University study cited by National Geographic found that deadly weather extremes may rise 50 percent by 2100.
