Nerd alert. My wife and I renewed our Skywarn Storm Spotter Training certification this evening.
The NWS relies on spotters to provide “ground truth” for some severe weather events, by reporting and confirming wind speeds, size of hail, amount of rain, size of downed trees, etc.
Spotters help “fill in the blanks” for the National Weather Service, to help them paint a fuller picture of weather events.
If you want to know more about shelf clouds, wall clouds, or how a Severe Thunderstorm Watch differs from a Severe Thunderstorm Warning, consider volunteering.
