chescowxman Posted November 22, 2022 Report Share Posted November 22, 2022 Below is my attempt at a Winter Forecast for Chester County PA. I identified 12 analog years that had similar average temperature departures for October (~2 degrees below normal) and November (~2 degrees above normal). Ten (10) of the twelve (12) featured below normal temperatures - with 8 of the 12 years having above normal snowfall. The coldest analog season was 1977-78, the snowiest was the winter of 2009-10 when we were buried under 86.7" of snow. The warmest was 1948-49, the least snowiest 1930-31. Overall, I predict below normal temperatures for December, January and February, but above normal March temperatures. Seasonal snowfall will be above average at 47" vs our 36" of average snowfall featuring above average snowfall for all winter months with the exception of March Below is the chart with the actual readings for the analog years. Let me know your thoughts and if any questions let me know. Wish me luck and get those snowblowers ready!! 2 Quote DISCLAMER: All historical weather data analytics posted here is specifically for the climate of Chester County PA. We continually analyze the actual raw non-adjusted NWS certified Coop and spotter observed climate data for the county. We make no post observation adjustments to any of the detailed analytics. Unlike NOAA, we do not apply any post observation adjustments to the historical raw data from the NWS observers. Climate change is natural and is not leading to future calamity. The only true “Climate Deniers” are people who think the climate should be unchanging. Specifically the Chester County PA analysis has only yielded normal and expected cyclical warming and cooling trends since the 1880's. Any model predictions of catastrophic climate change are not science. Pay little attention to data derived from climate models. To date we have yet to validate even one predicted climate or weather event attributable to climate change. Climate science is only advanced by continually questioning it and challenging it based on the actual climate data.
