Major Tornado Outbreak Forecast Today and Tonight
On the 40th anniversary of one of the worst tornado outbreaks in history, a tornado outbreak is forecast today and tonight.
Things have already started with this image, via Twitter, of the tornado damage in University City, MO, a suburb of St. Louis.
Needless to say, if you live in the threat areas below, keep up on the weather today!
Tornado Threat
You'll recall yesterday's probabilities were 5% (brown) which is the threshold of a significant tornado threat. There were tornadoes but they were weaker than I though they would be. That said, today has triple the threat and the hatching means that major tornadoes (equal or stronger than F-2 intensity) are possible.
Damaging Thunderstorm Wind Threat
This evening or tonight, the storms may congeal into a line near the Mississippi River. If so, damaging thunderstorm winds become quite possible. The significant threshold is 15% (yellow).
Large Hail Threat
Again, the significant threat for large (1" or larger) hail is 15% (yellow). The hatched area is where hail 2" or larger is forecast.
Friday and Friday Night
This the combined threat graphic (tornadoes, large hail, damaging winds). The yellow (15%) is the significant threshold.
