Here is more in depth information on these graphics. If you have any questions, hopefully the video will help answer them. Thanks for watching! #ilwx pic.twitter.com/Gseq5gmZnm
Do you know how the @NWS defines thunderstorm strength? The NWS will issue warnings only when a thunderstorm is severe. The @NWSSPC issues severe weather outlooks to highlight the thunderstorm & severe weather potential across the country. #ilwx pic.twitter.com/hsojSDzVBF
