The idea seems to be firmly entrenched that things are going to become quite noisy, and violent in the mid-section of the country during this time period.

lot depends if this comes out as one piece of energy or impulses... fairly broad base trough coming which has been know for some significant tornado outbreaks... areas frist to get in on the action appear east texas east central ok into northern louisiana , western ark... the threat looks to slide over the midsouth to include eastern ark, west tn. northern ms... late friday... interesting see what happens further east... system has one large nice warm sector with dps nearing 70 to lower ohio valley... this one needs to be closely watched folks.

Right in the heart of tornado alley.



SPC Day 4-8 Convective Outlook

...Friday/Day 8...
The ECMWF and GFS are in better agreement in the western U.S.,
developing a vigorous upper-level trough in the Four Corners region.
This coincides with strong moisture advection across the Great
Plains. The synoptic setup which the medium-range models have been
forecasting for a couple days, could result in a significant severe
weather event on Friday into Friday night across parts of the
southern and central Plains with tornadoes, large hail and wind
damage possible. Due to the potential for a higher-end event on
Friday, have added a 15 percent contour where model consensus places
the greatest chance of severe weather.

06z GFS suggests a threat even further south than that 15% area, all the way down into south-central TX.

Pretty strong wording in the Day 8 discussion, already talking about this as a potentially higher-end event.

The 12z EURO was an outlier of several of its previous runs, and of the GFS. But, if we start to see a trend in that direction, which is possible. I'd be really worried. Not that this threat doesn't already look quite bad without that run, but a setup like that shown on the 12z EURO could extend the seriousness of this threat over a much larger area.
