  Using the quasi-classical formalism we provide the description of the
temperature and field-direction dependence of the in-plane upper critical field
in layered superconductors, taking into account the interlayer Josephson
coupling and the paramagnetic spin splitting. We generalize the
Lawrence-Doniach model for the case of high magnetic fields and show that the
re-entrant superconductivity is naturally described by our formalism when
neglecting the Pauli pair breaking effect. We demonstrate that in layered
superconductors the in-plane anisotropy of the onset of superconductivity
exhibits four different\ temperature regimes: from the Ginzburg-Landau type in
the vicinity of the critical temperature $T_{c0}$ with anisotropies of
coherence lengths, up to the FFLO type induced by the strong interference
between the modulation vector and the orbital effect. Our results are in
agreement with the experimental measurements of the field-angle dependence of
the superconducting onset temperature of the organic compound (TMTSF)$_{2}
$ClO$_{4}$.
