CIPS Winter Storm
This Period In CIPS
The above figures represent a 30 year climatology of snow to liquid ratios that was compiled using NWS Cooperative Observer Summary of the Day data. Only snowfalls greater than 2" and liquid equivalents greater than 0.11" were included. Events estimated by NCDC were discarded. A station must have recorded at least 15 observations over the 30 year period to be included. The total number of stations included was 7760. Portions of the maps with no analysis contain no data for that grid point.
Further research in the coming months will involve an examination of individual storm systems in the NWS central region. The storms will be analyzed in order to determine the physical processes that create varying snow to liquid ratios.
