Is the misalignment of the Local Group velocity and the dipole generated by the 2MASS Redshift Survey typical in Λ cold dark matter and the halo model of galaxies?

We predict the acceleration of the Local Group generated by the 2MASS Redshift Survey within the framework of Lambda cold dark matter and the halo model of galaxies. We show that as the galaxy fluctuations derived from the halo model have more power on small scales compared with the mass fluctuations, the misalignment angle between the CMB velocity vector and the 2MASS Redshift Survey dipole is in reasonable agreement with the observed 21 degrees. This statistical analysis suggests that it is not necessary to invoke a hypothetical nearby galaxy or a distant cluster to explain this misalignment.
