Definitions:

Water Year: October 1 to September 30
Normal: The 1981-2010 average.
Percentile: Ranking with respect to data on the same day of the year for other years in the period of record. The ranking percentile is equal to the fraction of available years whose value is less than the current year's value. 100% means that all other years are less than the present value. 0% means that all other years are greater than or equal to the present value.
Record: Is the current value a record or near record for the date? For example, a "new record high" means that the current value is now the highest value on record. A "near record high" means that the current value is exceeded or tied by only one other value on record. This is not necessarily an all-season record.
Anomaly: For temperature, the departure of the current value from the median of data on the same day of the year for other years in the period of record.
SNOTEL (SNOwpack TELemetry):  An automated near real-time data collection network that provides mid to high elevation hydroclimatic data from mountainous regions of the western United States.  A standard SNOTEL station provides snow water equivalent, snow depth, precipitation, and temperature data.  The SNOTEL network is maintained by the USDA Natural Resources Conservation Service Snow Survey and Water Supply Forecasting Program.
ACIS: Data served by the Regional Climate Centers and the NOAA National Climate Data Center's "Applied Climate Information System". This includes the Cooperative Observer Network, the Hourly Surface Airways Network and the Historical Climatology Network and other regional networks.
