The "Total SWE Monday" Habit . . . Please give it a try!

The National Operational Hydrologic Remote Sensing Center utilizes CoCoRaHS reports of precipitation, snowfall, snow depth and the water equivalent of the snow on the ground every day. CoCoRaHS data provide critical "Ground Truth" information that can improve the skill of their products and models. This will improve the accuracy of flood forecasts in the weeks and months ahead. Click here to see how your CoCoRaHS SWE Reports are used by NOHRSC

Their guidance to us has been that if you can only report one day a week it’s best to all report on the same day. Monday was chosen:

"The analysts at NOHRSC prefer a Total Snow Water Equivalent (SWE) observation taken once a week on Monday. The simple reason is that digging cores every day ruins your sample snowfield area (unless you have a big yard or open fields nearby).

A flood of Monday morning SWE reports gives us a better picture of the overall snowpack instead of a few scattered results trickling in throughout the week. Daily total SWE would be great, but let's make "Total SWE Monday" a habit.

(Note: If you have the room, more frequent observations are appreciated, especially when conditions are changing. For areas that only infrequently get snow, there is no need to wait for Monday -- report SWE whenever you have the chance). For instructions on how to take core samples and report the snowpack SWE, please view our on-line training materials on snow: Training Slide Shows or watch the YouTube short animation on: SWE.



SPECIAL WEBINAR: A Review of Significant Weather Events Occurring in 2022


Significant Weather Events of 2022 will be the subject of our special "WxTalk Webinar” on Thursday, February 2nd. Join us as A Review of Significant Weather Events Occurring in 2022 is presented by Greg Carbin of NOAA’s Weather Prediction Center. 

Space is limited to the first 500 registrants, so register today! We will notify the first 500 who register of their acceptance to the Webinar. Those who aren't able to attend will be able to watch this episode on-line the following day.


Title: Special Webinar - CoCoRaHS WxTalk: A Review of Significant Weather Events Occurring in 2022 
Date: Thursday, February 2, 2023
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 2022.  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.
