TP = Total Precipitation
AVG SWE = Average Snow Water Equivalent for date listed above
AVG TP = Average Total Precipitation for date listed above
PCT SWE AVG = SWE as a Percent of Average SWE for that date
PCT TP AVG = TP as a Percent of Average TP for that date
Percent of Average Numbers are calculated only for those stations that report for a given date
A non-reporting station is eliminated from the calculation of overall averages, not treated as a 0
