Sunday has looked ugly for a while, and for a time, it looked like the more sure fire day of the two this weekend. Sunday's outcome will be determined by what happens Saturday overnight into Sunday morning and just how organized the low-level jet is. But if things cooperate, there could very well be a MDT+ type tornado event on Sunday as well as a ceiling for that day.Not to derail from what we’re talking about now, but doesn’t Sunday also have nasty potential too? These two days look like they have the chance to be historic.
