Saturday is currently looking like the first major tornado threat of the year. Still tough to lock down the details, due to timing differences between the models, but it looks like the target area is centered over eastern IA/western IL/northern MO attm.
Storm motions are currently holding at 30 kts. CAPE is forecast to be over 3000 j/kg. EHI at the surface is over 4, with over 7 aloft. Shear may be veered from the SE, and is running at 60 kts. Hodographs are showing large, clockwise curvatures. Capping doesn't look to be an issue...it could be a huge day.
I'll be out in the field with Mike Brady...stay tuned for what could be a historic day!
