To be precise, in 1999 there actually was only a slight risk that morning, it was upgraded to Moderate at 11:15AM.
For today there was a moderate, I believe, beginning yesterday or the day before. But that's fairly routine 9 times out of 10 you get a few tornadoes out in some field somewhere.
I disagree. I vividly remember a High risk in 1999.
The NWS upgrade the severe risk to High at 4 pm. So there was some warning that things were going downhill in the forecast department.
