We analyze temporal and spatial meson correlators in quenched lattice QCD at $T>~0.$ Below Tc we observe little change in the meson properties as compared with $T=0.$ Above Tc we observe new features: chiral symmetry restoration and signals of plasma formation, but also an indication of persisting ``mesonic'' (metastable) states and different temporal and spatial ``masses'' in the mesonic channels. This suggests a complex picture of QGP in the region (1--1.5)Tc.
