From 2000 through 2021, the SPC issued a Level 5 high-risk forecast an average of two to three days each year. The last two high-risk forecasts were issued on March 17 and March 25, 2021, in the Deep South. Both 2003 and 2010 had the most in any year – six – while a few recent years didn't have a single high risk, including 2020. From June 2014 unt...
April and May combined to account for nearly two-thirds of all high-risk days from 2000 through 2021, with 21 and 19, respectively. These months frequently have the right volatile mix of enough warm, humid air overlaid by a still-active spring jet stream. There have been high-risk outlooks issued in the fall and winter months, including a first-eve...
This century, all high risks have covered either parts of the Midwest (Mississippi Valley, Ohio Valley, Great Lakes), Plains (Dakotas to Texas) or South (Arkansas and Louisiana to Virginia and the Carolinas). Here is the breakdown of regions covered by each of the 63 high risks from 2000 through 2021 (some high risks covered multiple regions, so th...
We examined each of the 63 high-risk outlooks from 2000 through 2021 to determine how many of those forecasts rang true to the dire nature of the outlooks. Almost three-quarters (46) of the high-risk forecasts were solid. These not only included obvious cases, like the late-April 2011 Super Outbreak, but also some tougher, more out-of-season foreca...

"On the worst days we want people to take unprecedented action to protect themselves," Bentley wrote. If your area is in a high risk of severe thunderstorms, the government's most experience...
