This one sort of came out of left field. The euro was showing it about 8 days ago and then it came out and the gfs never looked impressive. But times, as they say, are changing. SPC now feels confident of what looks to possibly be a significant severe weather event Wednesday as they have released a say four enhanced risk. They are also mentioning discrete supercells being possible along with a squall line. The supercells will have a risk for all severe weather modes including tornadoes. Early this afternoon after we get the 12z model runs in I'll take a look and see what they say.
