Woodward is about 50 miles from the Vance AFB -88D. That is prime coverage (i.e., close but outside the clutter).
Except due to terrain much of NW Oklahoma is not covered well by Vance. That area along with the extreme NE panhandle are at the limits of KAMA and KDDC so we dont see much in the way of lower level shear etc.. Same as with the far NW panhandle into NE New Mexico and SE colorado.
