This data was prepared by GLISA in 2020 as part of the 2019 mini-grant competition. Click on each tab to learn more about each category and to access downscaled climate data and information for Erie. 


Erie is ranked among the fastest-warming cities in the nation according to Climate Central. In recent decades, temperatures have increased between 1.6 and 4.06 degrees. As higher temperatures reduce winter ice coverage on the Great Lakes, more moisture is available to feed lake-effect snowstorms like the one that dumped more than 156 inches of snow on Erie from December 2017 through February 2018.  Click here to learn more.

Water Levels 

Since the last glaciers retreated more than 10,000 years ago, Great Lakes water levels have varied dramatically. The difference between the amount of water coming into a lake and the amount going out is the determining factor in whether the water level will rise, fall, or remain stable.  When several months of above-average precipitation occur with cooler, cloudy conditions that cause less evaporation, the levels gradually rise. Likewise, prolonged periods of lower-than-average precipitation and warmer temperatures typically result in lowering of water levels. Click here to learn more.
