Monday's setup looks pretty decent on the new GFS over the south half of Missouri and the southern third of Illinois. Already cleared my schedule for Monday, so I'll be heading south if things continue to look this good. GFS sounding near the St. Louis area late Monday...

Just now starting to take a real good look at this setup. The latest GFS shows sort of an elongated surface low from northern Missouri down into Oklahoma. Mid and upper winds are fairly backed over the northern portion of the warm sector, so unless we get a stronger northern (closed) low it doesn't look too good further north. As it stands now the best shot for supercell action will be further south where mid and upper winds are more veered. If the mid and upper level jet structure changes, or if the northern low becomes more dominant then this will all change. Still time for some tweaks. Edited: for my first grade punctuation
