New Snowfall/Winter Weather Reporting Criteria for NWS State College SkywarnTM Spotters
In order to obtain more frequent, more detailed, and more complete snowfall (and winter precipitation) information, the NWS in State College is asking our SkyWarnTM Spotter Network to report using new criteria starting this winter season.

These new criteria will help us keep the best information flowing to the rest of the world. This should allow everyone to make better-informed decisions during these critical weather events.

In addition to the new criteria, we will also try to include a statement in our daily Hazardous Weather Outlook (HWO) when we request the spotters to report. The statement will be something like "Spotters...please report snowfall information."
The HWO is played on NOAA Weather Radio, and is accessible from the left-hand menu (near the top) of all of our web pages as "Hazardous Outlook."

Starting immediately, we are asking that our spotters report during winter weather events using the following criteria:

- When snow accumulation reaches 3 inches
- When snow accumulation reaches 6 inches
- Storm total after the snow ends (also water equivalent if possible)
- If snow is falling at the rate of more than 1 inch per hour

- Any occurrence of or accumulation of freezing rain
- Accumulation of ice of 1/4 (one-quarter) inch or more on trees or wires

- When forecast winter precipitation differs significantly from observed (i.e. snowing with no snow in forecast, sleet...when only snow is forecast...)
- Any other significant weather occurrence/oddity (i.e. flooding due to snow melt/ice jam, damage from strong winds not associated with a thunderstorm)

These new criteria are reflected in our What to Report page, as well.

We thank all of our volunteer SkyWarnTM Spotters for their diligence and willingness to help us, and to help their neighbors. If you have questions about the SkyWarnTM Program, or would like to become a Spotter, see the information on our SkyWarnTM Page(s).

Remember that our Snowfall Information page will contain links to all the current forecasts, and real-time information, past event and seasonal totals, and climatology (what is normal).
