Public Reports (as appropriate)
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

Co-Operative (CoOp) Station Observations (Daily)
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
