In an environment with little convection but quite a bit of shear, this can happen. CAPE values are low to non-existent in that region right now, but wind shear is quite high.
And since these are likely not elevated storms, I'm guessing strength is about EF0 to EF1....doesn't diminish the fact they are tornadoes, but everything they're saying about yesterday's Oklahoma outbreak is that a lot of the reported storms here were in the EF3 to EF4 category.
Batten 'em down.
