I’ve now uploaded the animations of estimates climatological probabilities of F/EF-1 or greater tornadoes, Hail 1″ or greater, and significant severe weather. The probabilities are estimated from the 30 year period of 1982-2011. Probability animations exist for tornadoes, hail, wind, and any severe. For more information check out the original post or the post on the “non-significant” severe! The raw images should become available on the Storm Prediction Center’s website in the coming weeks.
Because the image quality is a bit degraded in the animations, the color scales for each animation are listed below.
Any Significant Severe: 0.10%, 0.25%, 0.50%, 0.75%, 1.00%, 1.25%, 1.50%, 1.75+%
F/EF-1+ Tornado: 0.02%, 0.10%, 0.20%, 0.30%, 0.40%, 0.50%, 0.60%, 0.70+%
Significant (F/EF-2+) Tornado: 0.01%, 0.05%, 0.10%, 0.15%, 0.20%, 0.25%, 0.30%, 0.35+%
Significant (64kt+) Wind: 0.05%, 0.10%, 0.20%, 0.30%, 0.40%, 0.50%, 0.60%, 0.70+%
1″+ Hail: 0.10%, 0.50%, 0.75%, 1.00%, 2.00%, 3.00%, 4.00%, 5.00+%
Significant (2″+) Hail: 0.05%, 0.10%, 0.20%, 0.40%, 0.60%, 0.80%, 1.00%, 1.20+%
