Hilberg's Tips -- Snow - Trace, Zero or NA?
Here are a couple of things to keep in mind about snow measurements the next time you see flakes fly.
If you observe flurries at your location, but nothing accumulates on the ground or ends up in the gauge, you should report a Trace for precipitation AND a Trace for new snowfall. Remember, if you observe it's a trace - it doesn't have to fall in the gauge. If there is any snow showing on the ground at observation time but it is not measurable, then also report a Trace for Total Snow and Ice on the Ground.
If you are measuring snow during the winter, it is a good habit to enter a zero for new snowfall each day when you do not have snow and if you did have precipitation. In fact, it's a good idea to do this year 'round. (If your precipitation is zero, snowfall is automatically set to zero.) Total Snow and Ice on the Ground should also be a daily observation, whether or not it has snowed in the past 24 hrs. This is the total amount on the ground at your observation time. If there is no snow on the ground, enter zero. If there is less than one half inch or coverage is less than 50 percent, then enter a Trace for Total Snow and Ice on the Ground.
Some observers choose to not measure the depth of new snow during the winter. If you are not measuring snow, then leave the New Snowfall field as NA. A zero in any field implies a measurement.

REGISTRATION INFOTitle: Special Webinar - CoCoRaHS WxTalk: A Review of Significant Weather Events Occurring in 2020
Date: Thursday, January 28, 2021
Time: 1:00 PM Eastern, Noon Central, 11:00 AM Mountain, 10:00 AM Pacific
Greg will present an overview of hazardous weather episodes impacting life and property within the United States during 2020 (and the top 10 events in the past decade ending in 2019). Selected events will be presented in quasi-chronological order and described with photos, maps, and loops of satellite and radar data. While many of the events selected for this talk captured the attention of the media and public, some of these "meteorological memories" may have been forgotten as more substantial weather events occurred throughout the year. This review will highlight some of the "big stories", as well as smaller short-term events. The presentation will include descriptions of significant and deadly weather events of the past year including winter storms, tornadoes and floods. Along with the meteorological set-up for each event, an impact summary will also be provided.
