SGP/MFRSR/E31 - Shadowband bent by severe storm

Severe storms and a tornado passed very near the E31 facility on 4/15.  Something happened 
that caused the data covered by this DQR to look very strange.  The instrument must have 
physically shifted.  Standard alignment procedures on 4/24 resolved the issue.  The site 
ops technician found the shadowband was bent out of shape by the storm.
