In order to create and maintain as long and reliable record of winter storms as possible in North and South Carolina, the following list of winter storm and seasonal snow/sleet maps for the states of North and South Carolina were created from data and analyses provided by the Southeast Regional Climate Center (SERCC), National Centers for Environmental Information (NCEI), Midwestern Regional Climate Center (MRCC), local National Weather Service (NWS) Weather Forecast Offices (WFOs), NC & SC State Climate Offices, local media, as well as friends, colleagues, and acquaintances. All of the data was stringently checked and quality controlled to ensure accuracy, reliability, and consistency. In addition, some of the data provided here may be missing in some or all of the aforementioned sources, and were thus in some cases "derived". For example, analysis of snow-liquid ratios (or the amount of liquid water per amount of snow) from available nearby stations and voluntary observers was often used, provided that the QPF (i.e. quantitative precipitation forecast, or rainfall equivalent) was known, snow presumably fell but was not reported at a particular location, and the reported snow-liquid ratios were at least somewhat "realistic". The following data, website, and methodology for obtaining the data are preliminary, subject to change, and users are urged to proceed with caution while the data is further refined and more products are added to the website.
Although some stations have record spanning deep into the mid 19th century, the period of record of the maps will not begin until 1895, wherein the Weather Bureau, primarily through the aid of voluntary observers, began in earnest keeping a continuous, large-scale, quasi-consistent record of snow and sleet in NC & SC, and much of the rest of the US for that matter.
Please note that users can not only click on hyperlinks to individual storm dates but also each decade (except the 1890s), and all yearly titles are yet another hyperlink to a seasonal statewide snow and sleet accumulation map, estimated from the storms analyzed in each season. This site will be periodically updated as more winter storms are added to the archive
Any questions, comments, concerns, and/or feedback are strongly encouraged.
