Public Reports
When we obtain reports from across the region - whether from spotters, the general public, or solicited information from people like PennDOT or Emergency Personnel - we quality-check the data.  We then try to issue Public Information Statements that summarize this information. Latest 24-hr Snowfall Report Map MapOfReports example
Co-Operative (CoOp) Station Observations
  Once per day (usually around 7 am) more than 100 people across Central Pennsylvania send the NWS an observation covering the past 24 hours.  Most report rain and snow totals. See the daily data from the CoOperative Observers Map representing CoOp station locations

Departure from Normal Maps

(from the MARFC)

Drought declarations/cancellations are made at the State level (the Governor/DEP Secretary) through guidance provided by the State Department of Environmental Protection (DEP) using data, analyses, and forecasts from the National Weather Service (NWS), the Susquehanna River Basin Commission (SRBC), and the United States Geological Survey (USGS). It should also be noted that local municipalities and water authorities can ask for voluntary water conservation by their customers, and even impose mandatory restrictions, outside of Drought Declarations.
