• Actuarial Weather Extremes: Snowfall and Precipitation Analysis for Nov 2022 to Feb 2023
• March 2023
• During the period from November 2022 through February 2023, the United States (U.S.) experienced numerous major winter storms, affecting much of the Midwest and Northeast. In California and Nevada, a series of atmospheric rivers in late December and January led to unusually heavy rainfall and, in some locations, heavy snowfall. This analysis examines precipitation and snowfall totals across the entire November-to-February period which, in this report, we refer to as the “2022/2023 winter season”. Data for this period was ranked against data from prior winters, focusing solely on weather stations with at least 50 years of historical data. The results were plotted on maps, revealing that much of the Western U.S. and parts of the Midwest experienced relatively high snowfall and/or precipitation across winter 2022/2023, with some locations experiencing record highs. Conversely, much of the mid-Atlantic and the Southeast experienced relatively low precipitation or snowfall, with some locations experiencing record lows.
